Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to a Chinese patent application bearing application number 202210041854.9, filed with the China Patent Office on January 14, 2022, and entitled "Aerosol-generating product and manufacturing method thereof," the entire contents of which are incorporated herein by reference. The present invention relates to tobacco products and methods of making the same, and in particular to heat-non-combustion aerosol-generating substrates and products and methods of making the same. [Background technology]

[0002] With the increasing health consciousness of people, the changing concept of consumption, the advancement of science and technology, and the accelerating upgrading of products, the needs and interests of tobacco consumers are constantly changing. At the same time, influenced by factors such as tobacco regulations, the development of traditional cigarettes is restricted, and the emergence and development of new types of tobacco is inevitable, including heated non-combustion aerosol generating products.

[0003] The basic principle of a non-combustion aerosol generating product is to volatilize the low boiling point components of the aerosol generating base material in the aerosol generating product by heating the non-combustion aerosol generating product. The heating temperature of a non-combustion aerosol generating product is 500℃ or less, which is much lower than the combustion temperature of conventional cigarettes, 800℃, and it is possible to significantly reduce various harmful components generated by combustion at high temperatures.

[0004] The conventional typical technical forms of heated non-combustion aerosol-generating products mainly include sheet type and granule type. For the sheet type technology, as shown in FIG. 1, a Chinese patent application with publication number CN113163863A discloses an aerosol-generating product that can contain up to 200 aerosol-generating strips 2. If there are too many aerosol-generating strips, there will be more gaps in the aerosol-generating product. When the aerosol-generating product is inserted into a heating tool and heated, the presence of the excess gaps will cause poor thermal conductivity between the sheets. When a user inhales the sheet-type aerosol-generating product, the amount of aerosol generated in the first few inhalations is small, so a long period of preheating is required to continuously release a large amount of uniform aerosol. And since the aerosol-generating product obtained using the sheet production process has a high moisture content and a high temperature of the aerosol gas generated in the heating process, some aerosol-generating products also require an additional structural design including a cooling segment. In addition, since the combination of sheets has a directionality, a certain directional requirement must be met when the aerosol-generating product is inserted into the flat heating sheet of the heating tool, and if the direction of the flat heating sheet and the combination direction of the sheets are 90°, it is relatively difficult to insert the aerosol-generating product into the flat heating sheet. In addition, in terms of the manufacturing process, the sheet-type aerosol-generating product needs to be produced by crushing the aerosol-generating raw material, mixing the aerosol generating agent, the aerosol stabilizer, etc., and forming a sheet, and then processing the sheet into the aerosol-generating product, which is complicated in production process and expensive.

[0005] As for the granular type technology, as shown in FIG. 2, a Chinese patent application with publication number CN109512022A discloses a method for manufacturing an empty tube-filled heating non-combustion smoking product with a sealing film, in which a granular, filamentary, mixed filamentary and granular, or honeycomb-shaped smoking material 4 is packaged in a circular empty tube using a sealing film and a barrier sheet. Granular aerosol-generating products have poor thermal conductivity due to large gaps between the granules. In addition, the heating parts of currently available heating appliances are sheet-shaped or needle-shaped, and when a granular aerosol-generating product is inserted into the heating parts of the sheet-shaped or needle-shaped heating appliances and heated, the thermal conduction effect between the heating parts and the heated granular aerosol-generating product is poor. In addition, since the granular aerosol-generating product is in a granular state, it is necessary to perform a sealing process on the ends, while its granular nature makes it difficult to package, and a support or other method is required inside the product to barrier the granules and prevent them from loosening.

The porous and loose structure of the aerosol generating substrate has good heat conduction effect during heating and suction, which results in uniform heating and short preheating time. 2. When a porous and loose aerosol-generating substrate is inserted into the heating part of a heating appliance for heating, the insertion force into the heating part is small and the insertion direction does not matter. 3. When a gel substance is added to the aerosol-generating base material, the sealing properties of the gel substance can prevent volatile substances such as essence fragrances in the aerosol-generating base material from affecting the taste, and can also prevent the aerosol-generating base material from absorbing moisture and becoming damp. 4. After the aerosol-generating product undergoes high-frequency induction aging, the polymers in the plant raw materials of the aerosol-generating substrate absorb the high-frequency energy and are decomposed into low-molecular structures, causing the flavor of the raw materials themselves to disappear or be reduced. This not only achieves the purpose of aging the cigarette aroma, but also serves the role of insecticide and sterilization through high frequency. 5. The moisture content of the aerosol-generating base material is low, and the moisture content of the aerosol generated by heating is also low, so the temperature of the aerosol is low. Even if the smoker does not cool the aerosol when inhaling, the phenomenon of the mouth becoming hot to the point of being painful does not occur. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

However, the present invention may be embodied in many different forms and is not limited to the embodiments set forth below. Rather, these embodiments are provided in order to provide a more thorough and complete understanding of the present disclosure.

[0048] 3 and 4, which are schematic cross-sectional views in different directions of an aerosol-generating substrate 30 according to an embodiment of the present invention. Fig. 3 is a schematic cross-sectional view of the internal structure of the aerosol-generating substrate 30, and Fig. 4 is a schematic longitudinal-sectional view of the internal structure of the aerosol-generating substrate 30. In this embodiment, the aerosol-generating substrate 30 is a round rod-shaped body having a porous and loose structure inside, and the porous and loose structure is composed of a crystal block and plant The aerosol-generating substrate 30 of the present embodiment is a substrate in which the crystal blocks and the fiber filaments coexist, and gaps exist between the crystal blocks, and the gaps are arranged in a spatially non-uniform and irregular manner. When the aerosol-generating substrate 30 of the present embodiment is heated, it generates an aerosol, and the generated aerosol can pass through the internal irregular gaps so as to be inhaled by the smoker. Naturally, the aerosol-generating substrate 30 is not limited to a rod-shaped body, and any substrate having the above-mentioned internal structural characteristics is within the scope of protection of the present invention.

[0049] The aerosol-generating substrate 30 described in this embodiment has a porous and loose structure inside, and in the drying process step during the production of the aerosol-generating substrate 30, the swelling agent component in the raw material is heated to generate gas, causing the aerosol-generating substrate 30 to expand, and the water contained in the aerosol-generating substrate 30, which contains a large amount of moisture before drying, is evaporated by heating. In this embodiment, the gaps in the porous and loose structure formed by the swelling technology are arranged in a spatially non-uniform and irregular state, and compared with the sheet type and granule type of the conventional technology, the porosity in this embodiment is small, and the internal gaps can pass the aerosol generated by heating, while there is no through hole from one end to the other end of the aerosol-generating substrate 30, so that the aerosol-generating substrate 30 according to this embodiment has a larger inhalation resistance when not heated, compared with the conventional heat-not-burn cigarette.

[0050] 5 and 6, which are schematic cross-sectional views of the aerosol-generating substrate 30 according to the present embodiment after heating, in different directions. FIG. 5 is a schematic cross-sectional view of the internal structure of the aerosol-generating substrate 30 after heating, and FIG. 6 is a schematic cross-sectional view of the internal structure of the aerosol-generating substrate 30 after heating. When the aerosol-generating substrate 30 is heated, the internal voids gradually become larger, and the porosity also increases to a certain extent with the volatilization of substances such as aerosol and essence flavoring, and the suction resistance gradually decreases. When the aerosol-generating substrate 30 is heated and inhaled, the suction resistance is large the first time, and may exceed 1.5 KPa, 2.0 KPa, or 3.0 KPa. When inhalation is continued after the first time, the suction resistance gradually decreases, and after the third or fourth time, the suction resistance decreases to about 1.0 KPa, and further becomes less than 1.0 KPa, which is relatively suitable for inhalation by smokers. The aerosol-generating substrate 30 according to the present embodiment has the following characteristics. 1. Different heating times result in different suction resistances; 2. The suction resistance gradually decreases with heating time; 3. When not heated, the suction resistance is larger than that of conventional sheet types and granule types; 4. As heating time passes, the suction resistance becomes greater than or equal to that of conventional sheet types and granule types.

[0051] In this embodiment, the aerosol-generating substrate 30 may have a porous and loose structure in which the crystal blocks are bonded together, with small internal voids, good thermal conductivity, and uniform heating. Compared with the sheet-type and granule-type aerosol-generating substrates of the prior art, which have large voids and poor thermal conductivity, the aerosol-generating substrate 30 of the present invention has the advantages of being porous and loose inside, having small voids, good thermal conductivity, and uniform heating.

[0052] In the above embodiment, the aerosol-generating substrate 30 contains an aerosol-generating agent, which generates an aerosol when heated. When the aerosol-generating substrate 30 is heated by a heating component of a heating appliance, the aerosol-generating agent in the aerosol-generating substrate 30 reaches its boiling point and evaporates into an aerosol, which is inhaled by the smoker.

[0053] A method for producing the aerosol-generating substrate 30 according to the present invention will be disclosed below. The method for producing the aerosol-generating substrate 30 according to the present invention is realized in terms of the raw material components, molding and drying processes, etc. of the aerosol-generating substrate 30.

[0054] In terms of the raw material composition, the raw material components for producing the aerosol-generating substrate 30 include a leavening agent, a large amount of water, and a plant raw material. The leavening agent component in the raw material is heated during the drying process to generate gas (carbon dioxide, CO2), and the raw material expands due to the gas formed inside, and after the gas is released, the inside of the aerosol-generating substrate 30 becomes porous and loose. The aerosol-generating substrate 30 also contains a large amount of water, which evaporates during the drying process, causing the inside of the aerosol-generating substrate 30 to become porous and loose.

[0055] In the forming process of the aerosol-generating substrate 30 according to the present invention, first, the plant raw materials are pulverized, and then various essential flavors, tobacco extract, aerosol generating agent, aerosol base forming agent, aerosol base swelling agent, aerosol sustained-release agent, water, etc. are mixed to produce a paste-like material, which is then formed into the aerosol-generating substrate 30 before drying in a forming process. Among them, various plant raw materials are the main carriers of the aerosol-generating substrate 30, various essential flavors and tobacco extract provide various different flavors to the generated aerosol, the aerosol generating agent generates the aerosol when the aerosol-generating substrate 30 is heated, and the aerosol base forming agent forms the paste-like material into the required shape of the aerosol-generating substrate 30 to form the crystal block and the plantThe swelling agent can be permeated into the inside of the fiber filaments, and the swelling agent generates gas when heated in the baking or drying process of the aerosol-generating substrate 30, forming the inside of the paste-like material porous, and further making the aerosol-generating substrate 30 with the formed porous structure passable by aerosol. Since a large amount of moisture is added to the raw material blend of the aerosol-generating substrate 30, the weight ratio of moisture in the total raw material can reach 30 to 60%, and when a large amount of moisture is removed in the baking or drying process, the aerosol-generating substrate 30 is formed into a porous and loose structure. In the embodiment of the drying process of the present invention, the drying process used includes a microwave swelling drying process, a vacuum drying drying process, a vacuum freeze drying process, and a high frequency induction drying process, and the aerosol-generating substrate 30 can be swollen during the drying process to form a porous and loose structure.

[0056] According to the above disclosure, in the manufacturing embodiment of the aerosol-generating substrate 30 of the present invention, first, the plant raw material of the aerosol-generating substrate 30 is pretreated. The pretreatment of the plant raw material is mainly performed through natural fermentation or fermentation by fermentation enzymes to reduce unpleasant flavors in the plant raw material and improve the aftertaste. Next, in preparation for the subsequent molding of the aerosol-generating substrate 30, various raw materials for the manufacture of the aerosol-generating substrate 30 are mixed into a paste-like material. Then, the paste-like material is manufactured into a rod-shaped aerosol-generating substrate 30 by a tool. Finally, the paste-like aerosol-generating substrate 30 is baked and expanded by a drying process, and a large amount of water in the aerosol-generating substrate 30 is evaporated to obtain a loose aerosol-generating substrate 30.

[0057] In the drying process, the baking parameters need to be suitably controlled so that the aerosol-generating substrate 30 has a suitable hardness and a suitable porosity. The baking temperature should not be too high, because a baking temperature that is too high will cause the aerosol-generating substrate 30 to have too much hardness, making it difficult to insert the aerosol-generating substrate 30 into a heating tool for inhalation, and the tobacco extract and various essential flavors in the aerosol-generating substrate 30 will volatilize in large amounts, resulting in a poor taste. Only by selecting a suitable drying process can the aerosol-generating substrate 30 be guaranteed to have a certain porosity, and the aerosol can smoothly pass through the inside of the aerosol-generating substrate 30 during the heating and inhalation process.

[0058] The raw material composition of the aerosol-generating substrate 30 according to the present invention will be disclosed below.

[0059] The raw materials of the aerosol-generating substrate 30 include plant raw materials, tobacco extracts, essential flavors, aerosol generating agents, aerosol substrate forming agents, aerosol substrate expanding agents, aerosol sustained-release agents, and water.

[0070] The water is potable water that meets sanitary standards.

[0071] In another embodiment, when the heating tool has a component without a heating sheet, a metal material or a magnetic material can be added to the raw material composition of the aerosol-generating substrate 30, and the aerosol-generating substrate can be baked during the drying process using the high-frequency reaction principle. Since the aerosol-generating substrate 30 according to this embodiment has a metal material or a magnetic material inside, when the aerosol-generating substrate 30 is inserted into a heating tool without a heating sheet and heated, the aerosol-generating substrate 30 is heated by the Hall effect and can be further inhaled by the smoker.

[0072] In this embodiment, the metal material may be at least one of the metal elements such as iron, copper, aluminum, chromium, magnesium, zinc, titanium, cobalt, nickel, etc., but is not limited thereto, and the shape of the metal material may be granular, sheet-like, strip-like, rod-like, etc.

[0073] In this embodiment, the magnetic material may be at least one of magnetic materials such as iron, cobalt, nickel and their alloy particles, aluminum nickel (cobalt) alloy, iron chromium (cobalt) alloy, iron chromium (cobalt) alloy, iron chromium (cobalt) alloy, iron chromium molybdenum, iron aluminum carbon alloy, etc., but is not limited to these, and the shape of the magnetic material may be granular, sheet-like, strip-like, rod-like, etc.

[0074] The plant raw materials of this embodiment are rich in starch, protein, organic acids, flavoring substances, etc. when harvested, and have various degrees of defects in their inherent quality, such as a strong grassy off-flavor or high irritability. Various plant raw materials in an unprocessed state have a relatively large molecular structure, and the taste of the polymer structure itself is relatively strong, so it is difficult for the essence flavor to hide the taste of the polymer itself. For example, the protein content in tea leaves is 21 to 28%, and during the heating process, a pungent taste is generated, the irritation becomes stronger, the bitterness increases, and an unpleasant protein odor is generated.

[0075] Therefore, before producing the paste-like material, in the first step, the various plant raw materials of the aerosol-generating substrate 30 must be pretreated to reduce various unpleasant flavors of the plant raw materials.

[0076] The pretreatment of the plant material may be a natural fermentation of the plant material and a fermentation with a fermentation enzyme.

[0077] In this embodiment, natural fermentation is used to pre-treat the plant material of the aerosol-generating substrate 30 .

[0078] The natural fermentation of the plant raw materials involves storing at least one of herbal plants, Chinese medicinal plants, or tobacco raw materials in a warehouse at a certain temperature and humidity for a certain period of time to allow natural aging, where the selectable temperature is 18-25°C, the relative humidity is 60%-65%, and the storage period is 1-3 years. The natural aging of the plant raw materials can promote the conversion of the inherent chemical components of the plant raw materials, thereby reducing the unpleasant taste of the plant raw materials, reducing irritation, improving the aftertaste, and further making the smoke generated from the aerosol-generating substrate 30 during the heating process more mellow and delicate.

[0079] However, the aging process using natural fermentation of plant raw materials has a relatively long cycle and requires a large amount of warehouse space. Therefore, in order to shorten the aging time of plant raw materials, a fermentation method using fermentation enzymes can be used with biotechnology, which can significantly reduce the aging time.

[0080] As shown by many studies, by utilizing the individual or comprehensive effects of various enzymes, some proteins in the raw material can be hydrolyzed into a series of low molecular weight nitrogen-containing compounds, and these conversion products undergo Maillard reaction with reducing sugars, alcohol, etc. to produce edible or tobacco flavors, and the products have a rich nutty aroma, sauce aroma, roasted aroma, roasted aroma, fruity aroma, tobacco aroma and Chinese herbal aroma, which can effectively enrich the aroma of cigarettes and improve the smoking experience, thereby reducing the burnt odor and unpleasant taste in the raw material, improving the penetration of the aroma, harmonizing the smoke smell, reducing the burnt odor, etc., and making the ratio of the inherent chemical components of cigarettes more harmonious. In addition, short peptides and amino acids can also chemically react with phenolic compounds, pigment decomposition products, lipid molecules, etc., and the products can also improve the smoking quality of cigarettes.

[0081] In another embodiment, fermentation with fermenting enzymes is used to pre-treat the plant material of the aerosol-generating substrate 30 .

[0082] The method for fermenting the plant raw material with a fermentation enzyme involves mixing the fermentation enzyme and the plant raw material under an environment of constant temperature, humidity and pH and fermenting them, the fermentation enzyme is added at a rate of 0.001% to 1%, the fermentation temperature is 30 to 65°C, preferably 40 to 50°C, the fermentation pH value is 5.5 to 10, preferably 6.5 to 8.5, and the fermentation time is 10 to 30 days, and the type of fermentation enzyme used may be at least one of protease, pectinase, cellulase, lipase, etc.

[0083] After fermentation with the fermentation enzymes, proteins and other substances in the plant raw materials are broken down into other low molecular weight substances; for example, proteins can be broken down to produce short peptides, free amino acids, etc.; the burnt odor and unpleasant flavors that are generated from the high molecular weight substances in the plant raw materials during the heating process are reduced; the various chemical components in the plant raw materials are harmonised, and the aroma of the smoke is improved, thereby improving the smoking quality.

[0084] In the second step, various raw materials for the aerosol-generating substrate 30 are mixed into a paste in preparation for the molding of the aerosol-generating substrate 30 in the next step.

[0085] The present invention provides an embodiment of a method for producing a paste-like material for the aerosol-generating substrate 30. After the plant raw material is fermented by the fermentation enzyme, the preparation of the paste-like material for the aerosol-generating substrate 30 is started. The herbal plants, Chinese medicinal plants, tobacco raw materials or wood fibers after fermentation by the fermentation enzyme are pulverized in a grinder to a pulverized particle size of 10 μm to 500 μm, and one or a combination of the pulverized herbal plants, Chinese medicinal plants, tobacco raw materials or wood fibers is taken in a certain ratio and mixed uniformly to obtain a pulverized and uniformly mixed plant raw material. The above-mentioned crushed and uniformly mixed plant raw material is mixed in an amount of 40-80 parts, tobacco extract in an amount of 10-20 parts, aerosol generating agent in an amount of 30-60 parts, essence flavoring in an amount of 10-30 parts, aerosol base forming agent in an amount of 1-5 parts, aerosol base swelling agent in an amount of 1-3 parts, aerosol sustained-release agent in an amount of 1-10 parts, and water in an amount of 30-50 parts, and then mixed and stirred, and further stirred uniformly with a stirrer, to form the above-mentioned paste-like material, which may also be called a paste.

[0086] In this embodiment, when the herbal plant, the herbal medicine plant, the tobacco raw material or the wood fiber is crushed by a crusher, the crushed plant raw material powder contains granular matter and plant The fiber filaments are included, and the particle size of the granules is 10 μm to 500 μm. plant The outer diameter of the fiber filaments is between 5 μm and 30 μm, and the granules have an irregular shape.

[0087] In this example, in the prepared paste, the aerosol generating agent (e.g., glycerin), the essential fragrance, and water are mixed with the above granules and plant It penetrates into the interior of the fiber filaments.

[0088] In this embodiment, the paste prepared from the various raw materials of the aerosol-generating substrate 30 may be referred to as a slurry, a fluid slurry, a mixture, a wet material, a gel, a gum, or a paste, but it will be appreciated that the names may be replaced with other terms to achieve the same efficacy or effect as the paste of the present invention, without departing from the scope of the paste of the present invention in any case.

[0089] As can be seen from the above examples, the aerosol-generating substrate 30 according to the present invention has a relatively large water content, and the prepared paste-like material has appropriate humidity and hardness, and the water content is not too low. One of its main functions is to facilitate the formation of various raw materials into a paste-like material, and to facilitate the loading operation of the next step. That is, it allows the paste-like material to be extruded by an extruder, and at the same time, after a large amount of water in the raw materials is evaporated during the drying process, the micropores formed inside the aerosol-generating substrate 30 allow the aerosol generated from the aerosol-generating substrate 30 by heating with a heating tool to pass through smoothly, and an appropriate suction resistance is achieved. If the water content of the prepared paste-like material is too low, the extrusion difficulty of the extrusion device increases, while the density of the aerosol-generating substrate 30 increases, making it difficult for the aerosol to pass through. If the water content of the prepared paste-like material is too high, it is disadvantageous to the formation of the aerosol-generating substrate 30. Therefore, it is relatively appropriate that the prepared paste-like material has a moisture content of 30 to 60% by weight.

[0090] The third step involves loading and shaping the paste material of the aerosol-generating substrate 30 .

[0091] The aerosol-generating substrate 30 according to the present invention is extruded by a strip extruder, in which the driving device drives the material supplying device to extrude the paste-like material through the material outlet, and the extruded strip is then cut, or the extruded strip is then wrapped in a sheet wrapping material and then cut, or the extruded strip is directly pressed into a tubular wrapping material to obtain the unbaked aerosol-generating substrate 30.

[0092] The substrate extruded from the strip extruder may have a longitudinal cross-section that is circular, triangular, square, polygonal or irregular.

[0097] In this embodiment, the density of the extruded aerosol-generating substrate 30 can be controlled by controlling the extrusion speed and pressure of the material supply device 202; the higher the extrusion speed and the higher the pressure, the denser the extruded aerosol-generating substrate 30 will be, and conversely, the sparser the extruded aerosol-generating substrate 30 will be.

[0098] Preferably, the driving device 200 may be an electric drive, a hydraulic drive, an air pressure drive, or the like, and optionally, the material supply device 202 may be a piston device, a screw device, a pusher device, a pump device, or the like, and the pump device may be a gear pump, a centrifugal pump, a piston pump, an eccentric type pump, or the like.

Compared with the above embodiment, in this molding embodiment, the molding operation is not temporarily stopped due to the input of the material.

[0102] In this embodiment, the density of the extruded aerosol-generating substrate 30 can be controlled by controlling the extrusion speed and pressure of the material supply device 222; the higher the extrusion speed and the higher the pressure, the denser the extruded aerosol-generating substrate 30 will be, and conversely, the sparser the extruded aerosol-generating substrate will be.

[0104] Furthermore, a new aerosol-generating substrate forming apparatus can be obtained by adding a roll sheet packaging material 44 and a wrapping assembly to the material discharge port 232 of the aerosol-generating substrate forming apparatus 802, wrapping the aerosol-generating substrate extruded from the aerosol-generating substrate forming apparatus 802 in the roll sheet packaging material 44 by the wrapping assembly, and then cutting the aerosol-generating substrate with the wrapping material 32. The roll sheet packaging material 44 is shown in Fig. 9. Fig. 9 is a structural schematic diagram of the roll sheet packaging material 44.

[0105] Referring to FIG. 10, FIG. 10 is a structural schematic diagram of an aerosol-generating substrate-forming apparatus 804 in a further embodiment, and the aerosol-generating substrate 30 in this embodiment is produced by the aerosol-generating substrate-forming apparatus 804.

[0107] In this embodiment, the paste-like material is input from the material input port 248, and the material input device 244, driven by the driving device 246, feeds the paste-like material into the material cavity 262, and the material supply device 242, driven by the driving device 240, extrudes the paste-like material that has entered the material cavity 262 into a strip-shaped substrate through the material discharge port 252. The forming device 260 forms the roll sheet packaging material 44, and the forming device 260 also has a function of conveying the roll sheet packaging material 44, and matches the conveying speed of the roll packaging material 44 to the extrusion speed of the strip-shaped substrate.

[0108] In this embodiment, the density of the extruded aerosol-generating substrate can be controlled by controlling the extrusion speed and pressure of the material supply device 242; the higher the extrusion speed and the higher the pressure, the denser the extruded aerosol-generating substrate will be, and conversely, the sparser the extruded aerosol-generating substrate will be.

[0110] Referring to Figure 11, Figure 11 is a structural schematic diagram of an aerosol-generating substrate forming apparatus 806 in another embodiment, and the aerosol-generating substrate forming apparatus 806 includes a lower mold 270, a material passage 272, a material cavity 274, an upper mold 280, a mold cavity 282 jointly formed by the upper mold 280 and the lower mold 270, an exhaust port 284, a material discharge ejector pin 286, a driving device 288 for the material discharge ejector pin 286, a material supplying device 278 for feeding the paste-like material into the material cavity 282, and a driving device 276 for driving the material supplying device 278.

The mold cavity 282 is filled with the paste-like material and a certain pressure is maintained for a certain time so that the paste-like material is molded within the mold cavity 282, the maintained pressure being 3 to 20 kgf and the maintained time being 1 to 60 seconds, after which the operation of the driving device 276 is stopped, the supply of material by the material supplying device 278 is stopped, the upper mold 280 is removed, and the unbaked aerosol-generating substrate 116 molded within the mold cavity 282 is ejected by the material ejection ejector pin 286 under the drive of the driving device 288.

[0113] By adjusting the pressure and time of the material supply device 278, the paste-like material filled in the mold cavity 282 can be controlled; the higher the pressure and the longer the time, the more paste-like material is filled, and the denser the aerosol-generating substrate formed in the mold cavity 282 will be; or, conversely, the paste-like material may become sparse, even resulting in incomplete filling.

[0114] Preferably, the shape of the mold cavity 282 may be cylindrical, rectangular, oval, triangular, or the like.

[0115] Referring to Figure 12, Figure 12 is a structural schematic diagram of an aerosol-generating substrate forming apparatus 808 in another embodiment, and the aerosol-generating substrate 30 in this embodiment is manufactured by directly loading the paste-like material into a tubular packaging material 40 by the aerosol-generating substrate forming apparatus 808, and the paste-like material can be filled into a part of the tubular packaging material 40 to obtain an unbaked aerosol-generating substrate 118.

[0120] When the paste-like material is fed into the material cavity 300, the further the material supply device 292 is controlled to move away from the material discharge port 296, the more paste-like material is filled between the material supply device 292 and the material discharge port 296, and the more paste-like material is pushed into the tubular packaging material 40, making the paste-like material dense, or conversely, the paste-like material may become sparse and even cause incomplete filling.

That is, when the aerosol-generating substrate 124 is obtained and the ejector pin 320 has a certain length within the tubular packaging material 40, the aerosol-generating substrate 122 is obtained, and the length of the tubular packaging material 40 minus the length of the ejector pin 320 within the tubular packaging material 40 becomes the length of the aerosol-generating substrate 30 within the tubular packaging material 40.

[0127] After the position of the ejector pin 320 in the tubular packaging material 40 is determined, the amount of the paste-like material extruded can be controlled by controlling the position of the material supply device 308 in the material cavity when the paste-like material is fed into the material cavity 322, and the density of the paste-like material filled in the tubular packaging material 40 can be controlled. When the paste-like material is fed into the material cavity 322, the more the material supply device 308 is away from the material discharge port 318, the more the paste-like material filled between the material supply device 308 and the material discharge port 318 becomes, and the more the paste-like material is pushed into the tubular packaging material 40, and the paste-like material becomes dense, or conversely, the paste-like material becomes sparse, and even a phenomenon of incomplete filling may occur.

[0128] Referring to Figure 16, Figure 16 is a structural schematic diagram of an aerosol-generating substrate forming apparatus 812 in another embodiment, and the aerosol-generating substrate 30 in this embodiment is manufactured by loading the paste-like material into a tubular packaging material 40 by the aerosol-generating substrate forming apparatus 812.

[0129] The aerosol-generating substrate forming device 812 includes a material tube 326, a material pressing piston 328 attached inside the material tube 326, a lid 332 screwed onto one end of the material tube 326, a material outlet 330 at the other end of the material tube 326, a gas tube 334, a controller 336, and an ejector pin 338. The controller 336 can control the pressure and time of the output air pressure, the lid 332 is provided with a gas tube joint, the gas tube joint is connected to the gas tube 334, the other end of the gas tube 334 is connected to a gas tube joint of the controller 336, the gas tube 334, the lid 332, and the material tube 326 are in communication with each other, and the gas output from the controller 336 can enter the material tube 326 through the gas tube 334 and act on the material pressing piston 328.

[0130] In this embodiment, the paste-like material is loaded into the material tube 326, the material pressing piston 328 is inserted, the lid 332 is screwed on, the gas tube 334 is connected to the controller 336 and the lid 332, the tubular packaging material 40 is placed to the right of the material outlet 330, the tube outlet of the tubular packaging material 40 is aligned with the material outlet 330, and the ejector pin 338 is inserted into the tubular packaging material 40 to form a material filling cavity in the tubular packaging material 40. When the airflow pressure is adjusted to 4 to 10 kgf and the airflow output time to 1 to 60 s and the controller 336 is started, the airflow passes from the controller 336 through the gas pipe 334 and the lid 332, enters the material pipe 326 and pushes the material pressing piston 328 forward, so that the paste-like material in the material pipe 326 is loaded into the tubular packaging material 40 through the material discharge outlet 330, and when the ejector pin 338 is removed, the unbaked aerosol-generating substrate 30 is obtained.

[0131] Here, the length of the ejector pin 338 within the tubular packaging material 40 can occupy 0-100% of the tubular packaging material, and when the length of the ejector pin 338 within the tubular packaging material 40 becomes 0, the entire tubular packaging material 40 can be filled with the paste-like material. That is, when an unbaked aerosol-generating substrate 128 is obtained as shown in Fig. 17 and the ejector pin 338 has a certain length within the tubular packaging material 40, an unbaked aerosol-generating substrate 126 is obtained, and the length of the tubular packaging material 40 minus the length of the ejector pin 338 within the tubular packaging material 40 is the length of the aerosol-generating substrate 30 within the tubular packaging material 40.

[0132] After the position of the ejector pin in the tubular packaging material 40 is determined, the density of the paste-like material forced into the tubular packaging material 40 can be controlled by adjusting the magnitude and time of the output air pressure by the controller 336. The higher the pressure and the longer the time, the more paste-like material will be forced into the tubular packaging material 40 and the denser the filling will be, or conversely, the less the filling amount will be, and even the situation may occur where the filling is incomplete.

[0133] In the above-mentioned filling method, the paste-like material can only be loaded at one end of the tubular packaging material or loaded throughout the entire tubular packaging material, and the paste-like material cannot be loaded in the middle of the interior of the tubular packaging material.

[0134] Referring to Figure 18, Figure 18 is a structural schematic diagram of an aerosol-generating substrate forming apparatus 814 in another embodiment, and the aerosol-generating substrate 30 in this embodiment is manufactured by loading the paste-like material into a tubular packaging material 40 by the aerosol-generating substrate forming apparatus 814.

[0135] The aerosol-generating substrate forming device 814 includes a drive unit 348, a material supply unit 344 connected to the drive unit 348, a main body 340, a material inlet 341 on the main body 340, a material cavity 346 in the main body 340, a material outlet 342 on the main body 340, and an ejector pin 350.

[0136] In this embodiment, the paste-like material is fed into the material cavity 346 through the material feed port 341, the tubular packaging material 40 is placed on the right side of the material discharge port 342, and its tube port is aligned with the material discharge port 342, the ejector pin 350 is inserted into the tubular packaging material 40, and the driving device 348 drives the material supply device 344 to move to the right, so that the paste-like material in the material cavity 346 is pushed into the tubular packaging material 40 through the material discharge port 342, and the material supply device 344 drives the tubular packaging material 40 to move to the right. The paste-like material is pushed forward to the end opening of the tubular packaging material 40, and the paste-like material is fed into the tubular packaging material 40, and the paste-like material is filled into the space between the ejector pin 350 and the material supply device 344 in the tubular packaging material 40. When the material supply device 344 is driven by the drive device 348 to remove it from the tubular packaging material 40, and at the same time the ejector pin is pulled out from within the tubular packaging material 40, an unbaked aerosol-generating substrate 130 is obtained in which the paste-like material is loaded in the middle of the tubular packaging material 40.

[0137] The length and position of the paste-like material in the tubular packaging material 40 are determined by the positions of the material supply device 344 and the ejector pin 350 in the tubular packaging material 40, and the length and position of the paste-like material in the tubular packaging material 40 can be adjusted by adjusting the positions of the material supply device 344 and the ejector pin 350 in the tubular packaging material 40 to various positions. Of course, the premise is that a certain distance is maintained between the material supply device 344 and the ejector pin 350 so that the material supply device 344 and the ejector pin 350 do not collide with each other.

[0138] When the paste-like material is fed into the material cavity 346, the position of the material supply device 344 in the material cavity 346 can be adjusted to control the extrusion amount of the paste-like material. After the positions of the material supply device 344 and the ejector pin 350 in the tubular packaging material 40 are set, when the paste-like material is filled and entered into the material cavity 346, the further the material supply device 344 is from the material outlet 342, the more the paste-like material filled between the material supply device 344 and the material outlet 342, the more the extruded paste material, and the more the paste-like material filled in the tubular packaging material; and the closer the material supply device 344 is to the material outlet 342, the less the paste-like material filled between the material supply device 344 and the material outlet 342, the less the extruded paste material, and the less the paste-like material filled in the tubular packaging material. By controlling the extrusion amount of the paste-like material, the density of the paste-like material in the tubular packaging material 40 can be controlled.

[0139] The drive device 348 may be an electric drive device, a hydraulic drive device, a pneumatic drive device, or a screw drive device, and the material supply device 344 may be a piston device, a screw device, a pusher device, a pump device, etc., and the pump device may be a gear pump, a centrifugal pump, a piston pump, an eccentric type pump, etc.

[0140] In this molding embodiment, a material supply port may be opened on the side wall of the main body 340 in order to continuously fill the paste-like material into the material cavity 346, and the paste-like material enters through the material supply port on the side wall, and does not need to be charged through the material input port 341 at the rear end, which affects efficiency. The material supply port may further be provided with an automatic material supply mechanism, and the automatic material feed mechanism continuously fills the paste-like material into the material cavity 346 and provides it for the material feed device 344 to feed into the packaging material. The automatic material feed mechanism may include a drive device and a material feed device, and the drive device may be an electric drive device, a hydraulic drive device, a pneumatic drive device, and a spiral drive device, and the material feed device may be a piston device, a spiral device, a pusher device, a pump device, etc., and the pump device may be a gear pump, a centrifugal pump, a piston pump, an eccentric pump, etc.

[0141] As mentioned above, Fig. 18 Aerosol generating substrate molding device 800~ 814 Next, in order to solve the problem that the aerosol-generating substrate becomes wet due to absorption of moisture in the air, the present invention provides an aerosol-generating substrate forming apparatus 800 to 814 A separate aerogel generating device may be provided after the material discharge port and before the paste-like material is sent to the tubular packaging material 40. Hereinafter, the aerosol generating device will be described using the aerosol-generating base material forming device 800 shown in FIG. 7 as an example, but FIG. 8 to FIG. 18 Aerosol generating substrate forming device 802~ 814 The explanation of this will be omitted.

[0142] 19A, which is a structural schematic diagram of another embodiment of the aerosol-generating substrate-forming apparatus 800 of FIG 7, and the difference between this embodiment and the aerosol-generating substrate-forming apparatus 800 of FIG 7 is that a separate aerogel generator is provided at the material discharge port 208 of the aerosol-generating substrate-forming apparatus 800. The aerosol-generating substrate 30 of this embodiment is manufactured by injecting aerogel into the paste-like aerosol-generating substrate by the aerogel generator after the paste-like material passes through the aerosol-generating substrate-forming apparatus 80, and finally loading the paste into a tubular packaging material.

[0143] In this embodiment, the aerogel generating apparatus includes a container 203, a pump 205, a pipeline 207, and a pipeline 209, of which the container 203 is used to store a solution, and the pump 205 is used to pump the solution in the container 203 through the pipeline 207 and transport it to the material outlet 208 of the aerosol-generating substrate forming apparatus 800 through the pipeline 209.

[0144] In this embodiment, a first solution and a second solution are mixed in the container 203. The first solution is a bio-based polysaccharide or polyamino acid solution containing carboxylate groups, and the second solution is a divalent / trivalent metal ion solution. After mixing the first solution and the second solution, a gel is formed by ionic cross-linking due to the coordination effect between the metal ion and the carboxylate. The formed gel has a hermetic sealing effect.

[0145] In another embodiment, the first solution may be added when preparing the paste-like material to prepare a paste-like material containing the first solution. In the preparation process of the paste-like material, since the added first solution contains water, the water added when preparing the paste-like material may be appropriately reduced. In this way, it is possible to avoid the prepared paste-like material being too thin and difficult to mold. In the aerosol-generating substrate molding device 800, when the paste-like aerosol-generating substrate containing the first solution is extruded, the second solution in the container 203 is injected by the pump 205 at the material discharge port 208 of the aerosol-generating substrate molding device 800, and a crosslinking reaction occurs between the second solution and the first solution in the extruded paste-like aerosol-generating substrate, generating a gel-like paste-like aerosol-generating substrate.

[0146] Since the gel has a sealing effect, the gel substance in the aerosol-generating base material can confine the aerosol generating agent and the essential fragrance in the aerosol-generating base material at room temperature, making it difficult for the essential fragrance to volatilize. At the same time, since the aerosol generating agent has water absorption properties, the gel substance can also absorb moisture in the air and prevent the aerosol-generating base material from becoming damp.

[0147] When the aerosol-generating base material is heated, the aerosol generating agent in the aerosol-generating base material vaporizes to form an aerosol, and at the same time, the essence flavoring is mixed with the aerosol generating agent during paste preparation, and is also extracted when the aerosol generating agent vaporizes to form an aerosol.

[0148] In this embodiment, the first solvent of the gelling agent is rich in carboxylate ions and may be sodium alginate, sodium hyaluronate, propylene glycol alginate, polyaspartic acid, polylysine, polyglutamic acid, etc., and the concentration of the first solvent is 1% to 30%, and the second solvent is a food-grade high-value metal ion and may be calcium chloride solution, calcium lactate solution, magnesium chloride solution, zinc chloride solution, ferrous chloride solution, ferric chloride solution, etc., and the concentration of the second solvent is 1% to 30%.

[0149] In another embodiment, the first solvent of the gel is rich in phenolic hydroxy groups and may be tannic acid, geniposide, the first solvent is 1%-40%, and the second solvent of the gel is food grade valuable metal ion and may be calcium chloride solution, calcium lactate solution, magnesium chloride solution, zinc chloride solution, ferrous chloride solution, ferric chloride solution, etc., the concentration of the second solvent is 1%-30%.

[0150] In another embodiment, the first solvent of the gel is rich in aldehyde-based materials, such as oxidized sodium alginate, oxidized sodium hyaluronate, oxidized starch and its derivatives, oxidized guar gum and its derivatives, oxidized cellulose and its derivatives, oxidized xanthan gum and its derivatives, oxidized konjac gum and its derivatives, etc., and the concentration of the first solvent is 2% to 30%, and the second solvent is rich in amino-based materials, such as chitosan and its derivatives, polylysine, polyglutamic acid, polyaspartic acid, polyarginine, etc., and the concentration of the second solvent is 1 to 30%.

[0151] In another embodiment, the first solvent of the gelling agent is a dextrin-rich material, such as β-cyclodextrin, hydroxypropyl-β-cyclodextrin, methyl-β-dextrin, and the concentration of the first solvent is 5% to 30%, and the second solvent is adamantane-rich, such as adamantane graft, and the concentration of the second solvent is 5% to 30%.

[0152] In this embodiment, the first solution and the second solution are interchangeable, and this does not affect the effect of the aerosol-generating substrate according to the present invention. In other words, when preparing a paste-like material, if the second solution is added to prepare a paste-like material containing the second solution, the container 203 will contain the first solution.

[0153] The unbaked aerosol-generating substrate obtained in the above embodiments of the present invention has a relatively high moisture content and must undergo a subsequent baking step to obtain a porous, loose aerosol-generating substrate 30 suitable for insertion into and heating in a heating apparatus.

[0154] The aerosol-generating substrate 30 according to the present invention is in the form of a one-piece rod. The advantage of the one-piece aerosol-generating substrate 30 is that the thermal conduction effect is relatively good when the substrate is heated by the heating part of the heating appliance, and thus a better suction effect can be obtained.

[0155] In the fourth step, the shaped paste-like material substrate is dried and expanded through a drying process, thereby obtaining a loose aerosol-generating substrate 30.

[0156] In the drying process of the present invention, the drying process has a plurality of modes, and the baking mode is one of the drying modes of the drying process. The drying process is a critical step in the manufacturing process of the aerosol-generating substrate 30, and the porous, loose structure of the aerosol-generating substrate 30 is created during the drying process.

[0157] As shown in FIG. 20, FIG. 20 is a structural schematic diagram of an aerosol-generating substrate baking device 820 used in the baking embodiment, and low-temperature baking is performed using the aerosol-generating substrate baking device 820.

[0158] The aerosol-generating substrate baking apparatus 820 includes a box 406, a temperature sensor 404, and a heat source 402, and the heat source 402 may be of a heating type such as electric heating, air compressor heating, thermocouple heating, infrared heating, ultraviolet heating, magnetic induction heating, etc.

[0159] In this baking embodiment, at least one of the shaped, unbaked aerosol-producing substrates 110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 130, 134 obtained in the previous step is placed into box 406, the temperature is set to 30-80°C, preferably 45-65°C, the baking time is set to 60-400 minutes, and the aerosol-producing substrate is baked until the moisture content is 5-15% of the weight of the aerosol-producing substrate, and then removed, to obtain the baked aerosol-producing substrate 30 which is heated and can be inhaled.

[0160] The leavening agent may include sodium bicarbonate (NaHCO3), which undergoes a chemical reaction when heated and decomposes into sodium carbonate, carbon dioxide and water, according to the chemical equation: The aerosol-generating base leavening agent may include disodium dihydrogen pyrophosphate (Na2H2P2O7) and sodium bicarbonate, which undergo a chemical reaction when heated and decompose into sodium pyrophosphate (Na4P2O7), carbon dioxide and water. The chemical reaction formula is as follows: JPEG2025502238000065.jpg10170

[0161] During the baking process, the leavening agent in the raw material of the aerosol-generating base material 30 is thermally decomposed to generate gas, causing the base material of the paste-like material to expand and increase in volume, forming a loose, porous, paste-like structure with uniform pores inside.

[0162] During the baking process, a large amount of water contained in the paste-like material base material evaporates, reducing the density and hardness of the aerosol-generating base material 30 and making it suitable for insertion into and heating in a heating device.

[0163] Here, if the baking temperature of the aerosol-generating substrate baking device 820 is set to a low baking temperature of 30 to 80°C, the action of the leavening agent in the base material of the paste-like material can be fully exerted, and a porous and bulky structure can be generated inside the aerosol-generating substrate 30, which is favorable for the passage of the aerosol. If the baking temperature is set too high, the evaporation rate of water is fast, the leavening agent in the base material of the paste-like material is insufficient, and a dense and hardened base material is likely to be formed, which is unfavorable for the passage of the aerosol and for insertion of the heating device into the heating assembly.

[0164] The raw material for the aerosol-generating substrate 30 contains substances such as essential flavorings and tobacco extracts, and at high temperatures these substances are prone to volatilization, and flavor changes and losses occur, so the baking temperature in the baking process must not be too high.

[0165] Referring to FIG. 21, FIG. 21 is a structural schematic diagram of an aerosol-generating substrate baking apparatus 822 in another baking embodiment, and the aerosol-generating substrate 30 is baked and produced using the aerosol-generating substrate baking apparatus 822.

[0166] Aerosol-generating substrate baking apparatus 822 adds a thermal convection approach to aerosol-generating substrate baking apparatus 820, resulting in a more uniform overall temperature within the baking apparatus and improved consistency.

[0167] The aerosol-generating substrate baking apparatus 822 includes a box 410, a baking area 412, a moisture removal window 414, a return area 416, a partition plate 418, a temperature and humidity sensor 420, a heat source 422 and a fan 424. The partition plate 418 divides the inside of the box 410 into the baking area 412 and the return area 416. The moisture removal window 414 is provided near the airflow inlet of the return area 416. The temperature and humidity sensor 420 is provided at the return port of the return area 416. The fan 424 is provided near the heat source 422.

[0168] In this baking embodiment, the unbaked aerosol-generating substrate to be baked is placed in the baking area 412 of the aerosol-generating substrate baking device 822, and the heat generated from the heat source 422 is blown by the fan 424 onto the unbaked aerosol-generating substrate to be baked in the baking area 412, the unbaked aerosol-generating substrate is heated by the hot air flow and heat-exchanged with the unbaked aerosol-generating substrate, the moisture in the unbaked aerosol-generating substrate evaporates and mixes with the hot air flow, the hot air flow becomes a low-temperature air flow and a large amount of moisture is mixed in, the humidity becomes relatively high, and the low-temperature air flow the low-temperature air flows through the inlet of the reflux area into the reflux area 416, and is then refluxed through the reflux port to the heat source 422, where it is further heated and then sprayed again onto the aerosol-generating substrates 30 to be baked in the baking area 412, thereby making the overall temperature in the baking apparatus more uniform and improving consistency; when the low-temperature air flows through the temperature and humidity sensor 420 at the reflux port, the temperature and humidity sensor 420 detects the humidity in the low-temperature airflow; if the humidity is higher than a set value, the moisture removal window 414 is opened and the low-temperature airflow containing a large amount of moisture is discharged outside the box 410, thereby accelerating the baking of the unbaked aerosol-generating substrates.

[0169] Here, the baking temperature of the aerosol-generating substrate baking device 822 is set to 30 to 80°C, preferably 45 to 65°C, the baking time is set to 60 to 400 minutes, and the aerosol-generating substrate is baked until the moisture content is 5 to 15% of the weight of the aerosol-generating substrate, and then removed, to obtain the baked aerosol-producing substrate 30 which is heated and can be inhaled.

[0170] Similar to the principle of the baking embodiment of the aerosol-generating substrate 30 described above, since the paste-like material substrate contains a leavening agent and a large amount of moisture, the aerosol-generating substrate 30 can be sufficiently expanded during the baking process to produce a substrate with a porous and loose structure.

[0171] Referring to FIG. 22, FIG. 22 is a structural schematic diagram of an aerosol-generating substrate baking apparatus 824 in another baking embodiment, in which the aerosol-generating substrate baking apparatus 824 is used to bake the aerosol-generating substrate 30.

[0172] The aerosol-generating substrate baking device 824 bakes the unbaked aerosol-generating substrate in a microwave baking manner according to the principle of microwave expansion, so that the aerosol-generating substrate 30 has the characteristics of a porous structure.

[0173] The aerosol-generating substrate baking apparatus 824 includes a microwave box 430, a microwave generator 432, and a baking area 434, and is further equipped with a vacuum system 436 to reduce the air pressure in the oven, lower the evaporation temperature of the water, and accelerate the baking process.

[0174] The microwave frequency band selected by the aerosol-generating substrate baking apparatus 824 is the commonly used industrial microwave frequency band of 915 MHz±5 MHz or 2450 MHz±5 MHz, the temperature adjustable range of the oven cavity of the microwave box 430 is 10-100°C, and the vacuum exhaust range of the baking area 434 is 0-101 KPa.

[0175] In this baking embodiment, the paste-like material substrate to be baked is placed in the baking area 434 of the aerosol-generating substrate baking device 824, the baking temperature is set to 30 to 80°C, preferably 45 to 65°C, the vacuum degree is set to 0 to 101 KPa, preferably 30 to 60 KPa, the microwave power is adjusted according to the amount of material put in to be 0.8 to 4.0 KW, preferably 1.0 to 2.5 KW per kilogram of material, the baking time is set to 10 to 60 minutes, and the aerosol-generating substrate is removed at the point where the moisture content is 5 to 15% of the weight of the aerosol-generating substrate, thereby obtaining a baked aerosol-producing substrate 30 that can be heated and inhaled.

[0176] To further optimize the microwave baking procedure, the baking step may cycle the baking procedure by performing microwave baking for a certain time, then turning the microwave off for a certain time, then restarting microwave baking, and then turning it off again, preferably with a microwave baking time of 1-5 minutes and a microwave off time of 1-3 minutes. After the aerosol-generating substrate 30 has been baked, the aerosol-generating substrate baking apparatus 824 is turned off and the aerosol-generating substrate 30 is removed.

[0177] Generally, a substance is composed of polar and non-polar molecules. Under the action of a microwave electromagnetic field, the polar molecules in the medium change from their original thermal motion state to an arrangement and orientation that follows the alternation of the microwave electromagnetic field. When microwave radiation is performed on the paste-like aerosol-generating substrate 30 using a microwave frequency of 2450 MHz, the polar molecules in the paste-like aerosol-generating substrate 30 are arranged 2.45 billion times per second, and intense friction occurs between the molecules, so that heat is generated inside the paste-like aerosol-generating substrate 30, and a direct conversion from electrical energy to thermal energy in the medium is achieved.

[0178] In this baking embodiment, the microwave energy is converted into heat energy when it reaches the inside of the paste-like unbaked aerosol-generating substrate by radiation conduction of electromagnetic energy, so that the water molecules inside the paste-like unbaked aerosol-generating substrate absorb the microwave energy, and the moisture from deep inside the paste-like unbaked aerosol-generating substrate rapidly evaporates to form a high internal vapor pressure. Because the heating rate of microwaves is very fast, the vapor formation rate inside the paste-like unbaked aerosol-generating substrate is higher than the vapor transfer rate, and a vapor pressure gradient is generated inside the paste-like unbaked aerosol-generating substrate. When the pressure exceeds the allowable capacity of the structural strength of the material structure of the paste-like unbaked aerosol-generating substrate, the material of the paste-like unbaked aerosol-generating substrate expands, and the expansion force of gas causes structural denaturation of the polymeric substance in the material of the paste-like unbaked aerosol-generating substrate, so that the inside of the paste-like unbaked aerosol-generating substrate has the characteristics of a porous structure.

[0179] The moisture content has an important effect on the microwave energy absorption ability of the raw material in the paste-like unbaked aerosol base material. The higher the moisture content in the paste-like unbaked aerosol base material, the longer the evaporation time during swelling, which affects the swelling effect and productivity. The lower the moisture content, the less the internal pressure required for swelling can be generated during swelling, and the lower the swelling rate of the paste-like aerosol base material. In the embodiment of the present invention, the moisture content of the paste-like unbaked aerosol-generating base material is 30-60% of the weight of the paste-like unbaked aerosol-generating base material, and a good swelling effect is achieved.

[0180] The boiling point of water is related to atmospheric pressure. The boiling point of water varies depending on the atmospheric pressure. At a standard atmospheric pressure of 101 KPa, the boiling point of water is 100°C. As the atmospheric pressure decreases, the boiling point of water decreases. Under pressure conditions where the atmospheric pressure is reduced to 30-60 KPa, the boiling point of water drops to 40-60°C.

[0181] In this baking embodiment, when the inside of the microwave box 430 is evacuated, the evaporation temperature of the water in the paste-like unbaked aerosol-generating substrate can be reduced; when the inside of the microwave box 430 is evacuated to 30-60 KPa, the water in the paste-like unbaked aerosol-generating substrate will reach the evaporation temperature at 40-60°C, which further accelerates the formation rate of steam inside the paste-like unbaked aerosol-generating substrate, which is beneficial to the swelling effect of the material of the paste-like unbaked aerosol-generating substrate.

[0182] Furthermore, in this embodiment, the microwave baking may be performed using a method in which vacuum microwave baking and normal pressure microwave baking are combined. In the microwave baking step, first, the aerosol-generating substrate baking device 824 is subjected to vacuum microwave baking for 1 to 5 minutes, then the inside of the aerosol-generating substrate baking device 824 is released to 1 atmospheric pressure and normal pressure microwave baking is performed for 1 to 5 minutes, and again the aerosol-generating substrate baking device 824 is subjected to vacuum microwave baking for 1 to 5 minutes, and further normal pressure microwave baking is performed for 1 to 5 minutes, and so on, until the aerosol-generating substrate 30 is baked.

[0183] Furthermore, in this embodiment, the microwave device may further include a rotating mechanism, and the rotating mechanism may further include a loading tray, and the unbaked aerosol-generating substrate is placed on the loading tray in the rotating mechanism, and during baking by microwaves, the tray is rotated within the microwave device by the rotating mechanism, so that the aerosol-generating substrate can be heated uniformly within the microwave device.

[0184] By baking using a microwave method, the moisture in the unbaked aerosol-generating substrate can be quickly evaporated and the paste-like material can be quickly expanded to form an integrated porous and loose structure that adheres closely to the inner wall of the packaging material 32. Since the paste-like material contains a large amount of moisture, after the material expands and the moisture evaporates, a large number of micropores are generated inside the aerosol-generating substrate 30, and the porosity of the micropores reaches 40 to 75%.

[0185] In the baking process, the leavening agent in the raw material of the aerosol-generating substrate 30 is thermally decomposed to generate gas, so that the paste-like unbaked aerosol-generating substrate is expanded, the volume increases, and a loose structure with a porous and uniform pores is formed. The principle by which the leavening agent in the aerosol-generating substrate 30 is thermally decomposed to generate gas has been explained in the above embodiment, so it will not be repeated here.

[0186] In the baking process, a large amount of water contained in the raw materials of the aerosol-generating substrate 30 evaporates, reducing the density and hardness of the aerosol-generating substrate 30 and making it suitable for insertion into and heating in a heating device.

[0187] In this baking embodiment, by fully utilizing the microwave expansion technology, the principle that the boiling point of water decreases under reduced pressure, and the expansion effect of the expander in the raw materials of the aerosol-generating substrate 30, the voids in the internal structure of the aerosol-generating substrate 30 become more uniform, the structure is porous and loose, the hardness of the aerosol-generating substrate 30 after baking is in the range of 0.5 to 2.5 kgf, the strength of the force for insertion into the heating tool is relatively appropriate, and the aerosol-generating substrate 30 does not harden during the baking process and become unable to be inserted into the heating part of the heating tool.

[0188] In this baking embodiment, the microwave baking temperature is also set to a baking temperature of 30 to 80°C, preferably 45 to 65°C, so that the ingredients such as the essence flavoring, tobacco extract, etc. in the raw materials of the aerosol-generating substrate 30 are effectively preserved, and there is no large-scale volatilization, flavor change, or loss of the ingredients such as the essence flavoring, tobacco extract, etc. in the raw materials of the aerosol-generating substrate 30, so that the inhalation flavor of the aerosol-generating substrate 30 is guaranteed.

[0189] In the embodiment of baking the aerosol-generating substrate 30, both the microwave baking and the heat convection baking may be used. First, the unbaked aerosol-generating substrate 30 is preliminarily baked by the microwave baking device 824 in the manner described in the above embodiment, and the aerosol-generating substrate 30 is expanded under the action of microwaves while removing 10-60% of the moisture content in the unbaked aerosol-generating substrate. The semi-baked aerosol-generating substrate 30 is then taken out, and after waiting until the temperature drops to 20-25°C, the semi-baked aerosol-generating substrate 30 is placed in the aerosol-generating substrate baking device 822, and the semi-baked aerosol-generating substrate 30 is baked in the manner described in the above embodiment until the moisture content is 5-15% of the weight of the aerosol-generating substrate, and then taken out to obtain the baked aerosol-producing substrate.

[0190] The combination of microwave baking by the aerosol-generating substrate baking device 824 and thermal convection baking by the aerosol-generating substrate baking device 822 can fully bring into play the advantages of both baking methods. Microwave baking has high baking efficiency and microwave puffing effect, and can quickly remove the moisture in the unbaked aerosol-generating substrate 30 to achieve the purpose of puffing; at the same time, the thermal convection baking method is used to further bake the semi-baked aerosol-generating substrate 30, so that the internal texture of the baked aerosol-generating substrate 30 can be made more uniform, and the drying process is more stable and controllable.

[0191] In this embodiment of the baking of the aerosol-generating substrate 30, the microwave baking step may be performed by combining the vacuum microwave baking and atmospheric microwave baking in the above embodiment, and the unbaked aerosol-generating substrate 30 is baked by a thermal convection baking method after 10-60% of the moisture content is removed by microwave expansion.

[0192] Referring to FIG. 23, FIG. 23 is a structural schematic diagram of an aerosol-generating substrate baking apparatus 826 in another baking embodiment, in which the aerosol-generating substrate baking apparatus 826 is used to bake the aerosol-generating substrate 30.

[0193] In this embodiment, the aerosol-generating substrate baking device 826 uses a vacuum drying method to heat the unbaked aerosol-generating substrate 30 under vacuum exhaust, thereby lowering the boiling point of water in the unbaked aerosol-generating substrate 30 and increasing the baking speed of the unbaked aerosol-generating substrate 30.

[0194] The aerosol-generating substrate baking apparatus 826 includes a box 440 , a baking area 442 , a heat source 444 , and a vacuum pumping system 446 .

[0195] In this baking example, the unbaked aerosol-generating substrate 30 is placed in the baking area 442, the baking temperature is set to 30 to 80° C., preferably 45 to 65° C., the degree of vacuum is set to 10 to 90 KPa, preferably 30 to 60 KPa, the time is set to 30 to 900 minutes, and the device is started to vacuum-dry the unbaked aerosol-generating substrate 30. Here, the evacuation may be performed by starting a vacuum pump to dehumidify the substrate, and the aerosol-generating substrate is dried until the moisture content of the substrate is 5 to 15% of the weight of the substrate, and the baked aerosol-generating substrate 30 is taken out to obtain a baked aerosol-generating substrate 30 that can be heated and sucked.

[0196] Since the vacuum drying is static vacuum drying, the shape of the aerosol-generating substrate 30 is not destroyed, and at the same time, since the drying temperature is relatively low, within the range of 30 to 80°C, the aerosol-generating substrate 30 does not harden after drying.

[0197] In the baking process, the leavening agent in the raw material of the aerosol-generating substrate 30 is thermally decomposed to generate gas, so that the paste-like aerosol-generating substrate 30 expands, increases in volume, softens in volumetric structure, and forms a loose structure that is porous and has uniform pores. The principle by which the leavening agent in the aerosol-generating substrate 30 is thermally decomposed to generate gas has been explained in the above embodiment, so it will not be described again here.

[0198] During the baking process, a large amount of water contained in the raw materials of the aerosol-generating substrate 30 evaporates, reducing the density and hardness of the aerosol-generating substrate 30 and making it suitable for insertion into and heating in a heating device.

[0199] In the embodiment of baking the aerosol-generating substrate 30, both the microwave baking and the vacuum dry baking may be used. First, the aerosol-generating substrate baking device 824 is used to perform preliminary microwave baking on the unbaked aerosol-generating substrate 30 in the manner described in the above embodiment, the unbaked aerosol-generating substrate 30 is expanded under the action of microwaves, and 10-60% of the moisture content in the unbaked aerosol-generating substrate 30 is removed, the semi-baked aerosol-generating substrate 30 is taken out, and after waiting until the temperature drops to 20-25°C, the semi-baked aerosol-generating substrate 30 is put into the aerosol-generating substrate baking device 826, and the semi-baked aerosol-generating substrate 30 is baked in the manner described in the above embodiment until the moisture content is 5-15% of the weight of the aerosol-generating substrate 30, and the aerosol-producing substrate 30 is taken out, whereby the baked aerosol-producing substrate 30 is obtained.

[0200] The combination of the microwave baking by the aerosol-generating substrate baking device 824 and the vacuum drying baking by the aerosol-generating substrate baking device 826 can fully bring into play the advantages of both baking methods. Microwave baking has high baking efficiency and good microwave puffing effect, and can quickly remove the moisture in the unbaked aerosol-generating substrate 30 to achieve the purpose of puffing; at the same time, by further baking the semi-baked aerosol-generating substrate 30 using the vacuum drying method, the shape of the aerosol-generating substrate 30 is not destroyed because the vacuum drying is static vacuum drying, and the internal tissue structure of the aerosol-generating substrate 30 can be made more uniform, the drying process is more stable and controllable, and the function of insecticide and sterilization by microwave is achieved.

[0201] In this embodiment of baking the aerosol-generating substrate 30, the microwave baking step can be performed by combining the vacuum microwave baking and normal pressure microwave baking in the above embodiment, and the unbaked aerosol-generating substrate 30 is dried by a vacuum drying method after 10-60% of the moisture content is removed by microwave expansion.

[0202] Referring to FIG. 24, FIG. 24 is a structural schematic diagram of a baking apparatus 828 for the aerosol-generating substrate 30. In another embodiment, the aerosol-generating substrate 30 is dried using the baking apparatus 828 for the aerosol-generating substrate 30.

[0203] The aerosol-generating substrate baking device 828 uses a freeze-drying method. The freeze-drying method is a drying technique that utilizes the principle of sublimation, in which the material to be dried is quickly frozen at a low temperature, and then the frozen water is directly sublimated into water vapor under an appropriate vacuum environment and released. The product obtained by freeze-drying is called a freeze-dried product, and the process is called freeze-drying. The material is always at a low temperature (frozen state) before drying, and the ice crystals are uniformly distributed within the material. In the sublimation process, there is no concentration phenomenon due to dehydration, and side effects such as the generation of bubbles due to water vapor and oxidation are avoided. The dried material is porous like a dry sponge, and the volume basically does not change, and physical, chemical, and biological denaturation of the dried material is prevented to the maximum extent possible.

[0204] The aerosol-generating substrate baking apparatus 828 includes a vacuum drying box 450, a drying area 452 within the vacuum drying box 450, a heat source 454 within the vacuum drying box 450, a vacuum system 456 for applying a vacuum to the vacuum drying box 450, a freezing box 458, a freezing area 460 within the freezing box 458, and a cooling system 462 for freezing the materials within the freezing box 458.

[0205] In this embodiment, the unbaked aerosol-generating substrate 30 is placed in the freezing area 460 in the freezing box 458, and then the cooling system 462 is started to freeze the unbaked aerosol-generating substrate 30 to −55° C. to 0° C., and the unbaked aerosol-generating substrate 30 is completely crystallized and then taken out to obtain the crystallized aerosol-generating substrate 30. At this time, the moisture in the crystallized aerosol-generating substrate 30 turns into ice crystals and is uniformly distributed inside the crystallized aerosol-generating substrate 30, and then the crystallized aerosol-generating substrate 30 is placed in the drying area 452 in the vacuum drying box 450 and vacuum dried.

[0206] The drying temperature of the vacuum drying box 450 is set to 30 to 80°C, preferably 45 to 65°C, the degree of vacuum is set to 10 to 90 KPa, preferably 30 to 60 KPa, the time is set to 30 to 900 minutes, and the device is started to vacuum-dry the crystallized aerosol-generating substrate 30. The crystallized aerosol-generating substrate 30 is always at a low temperature (frozen state) before drying, and the ice crystals are uniformly distributed inside the crystallized aerosol-generating substrate 30, and the ice crystals are heated and sublimated. In the drying and sublimation process, there is no concentration phenomenon due to dehydration, and side effects such as the generation of bubbles due to water vapor and oxidation are avoided. The aerosol-generating substrate 30 after drying is sponge-like, and the volume basically does not change, and physical, chemical and biological denaturation of the aerosol-generating substrate 30 is prevented to the maximum extent. When the aerosol-producing substrate 30 is dried until the moisture content in the aerosol-producing substrate 30 becomes 5 to 15% of the weight of the aerosol-producing substrate 30, a dried aerosol-producing substrate 30 that can be heated and inhaled is obtained.

[0207] If the aerosol production substrate is dried using freeze-drying technology, the aerosol production substrate does not experience contraction or expansion phenomena, the inside of the aerosol production substrate is sponge-like, allowing the aerosol generated by heating the aerosol production substrate to pass through smoothly, and since the aerosol production substrate is dried at a low temperature, the aerosol production substrate does not become hardened and cannot be inserted into the heating part of a heating tool, and the aerosol production substrate obtained using the freeze-drying method has a hardness of 0.5 to 2.5 kgf and is easy to insert into the heating part of a heating tool.

[0208] In the drying process, the leavening agent in the raw material of the aerosol-generating substrate 30 is thermally decomposed to generate gas, so that the paste-like aerosol-generating substrate 30 expands, increases in volume, softens in volumetric structure, and forms a loose structure that is porous and has uniform pores. The principle by which the leavening agent in the aerosol-generating substrate 30 is thermally decomposed to generate gas has been explained in the above embodiment, so it will not be described again here.

[0209] In the drying step, a large amount of water contained in the aerosol-generating substrate 30 evaporates, reducing the density and hardness of the aerosol-generating substrate 30 and making it suitable for insertion into and heating in a heating device.

[0210] In an embodiment of drying the aerosol-generating substrate 30, both the microwave baking and freeze-drying baking methods may be used. First, the unbaked aerosol-generating substrate 30 is preliminarily baked by the microwave baking device 824 in the manner described in the above embodiment, the unbaked aerosol-generating substrate 30 is expanded under the action of microwaves, and 10-60% of the moisture content in the aerosol-generating substrate 30 is removed, and the half-baked aerosol-generating substrate 30 is then taken out and placed in the freezing area 460 in the freezing box 458 of the baking device 828. and then the cooling system 462 is started to freeze the semi-baked aerosol-generating substrate 30 to -55°C to 0°C, and the water in the semi-baked aerosol-generating substrate 30 is completely crystallized before being taken out to obtain a crystallized aerosol-generating substrate 30. Thereafter, the crystallized aerosol-generating substrate 30 is placed in the drying area 452 of the vacuum drying box 450 and dried in the manner of the above embodiment until the water content of the crystallized aerosol-generating substrate 30 becomes 5 to 15% of the weight of the aerosol-generating substrate 30, thereby obtaining a dried aerosol-producing substrate 30.

[0211] The combination of microwave baking by the aerosol-generating substrate baking device 824 and freeze-drying and baking by the aerosol-generating substrate baking device 828 can fully utilize the advantages of both baking methods. Microwave baking has high baking efficiency and good microwave swelling effect, and can quickly remove the moisture in the unbaked aerosol-generating substrate 30 to achieve the purpose of swelling. At the same time, by further baking the crystallized aerosol-generating substrate 30 using the freeze-drying baking method, the moisture in the crystallized aerosol-generating substrate 30 is always at a low temperature (frozen state) before drying, and the ice crystals are uniformly distributed in the crystallized aerosol-generating substrate 30. In the sublimation process, there is no concentration phenomenon due to dehydration, and side effects such as the generation of bubbles due to water vapor and oxidation are avoided. After baking, the aerosol-generating substrate 30 is a dry sponge-like porous substrate, and the volume basically does not change, and the physical, chemical and biological degeneration of the aerosol-generating substrate 30 is prevented to the maximum extent.

[0212] In an embodiment of drying the aerosol-generating substrate 30, first, the unbaked aerosol-generating substrate 30 is placed in the freezing area 460 in the freezing box 458 of the baking device 828 to freeze the unbaked aerosol-generating substrate 30 to −55° C. to 0° C., and the moisture in the unbaked aerosol-generating substrate 30 is completely crystallized, and then the unbaked aerosol-generating substrate 30 is taken out to obtain a completely crystallized aerosol-generating substrate 30, which is then placed in the baking device 824, and the crystallized aerosol-generating substrate 30 may be microwave baked by the method of the above embodiment, and the microwave baking process may be performed using a vacuum method. The aerosol-generating substrate 30 is baked until the moisture content is 5 to 15% of the weight of the aerosol-generating substrate 30, to obtain the baked aerosol-producing substrate.

[0213] In this drying embodiment, before microwave baking, the unbaked aerosol-generating substrate 30 is first frozen, and then baked using a vacuum microwave baking method, so that the aerosol-generating substrate 30 is always at a low temperature (frozen state) before drying, and the ice crystals are uniformly distributed within the material, so that in the sublimation process, there is no condensation phenomenon caused by dehydration, and side effects such as the generation of bubbles due to water vapor and oxidation are avoided. At the same time, because the baking efficiency of microwaves is high, the moisture in the aerosol-generating substrate 30 can be quickly removed, and the baking and insecticidal sterilization can be accelerated.

[0214] In an embodiment of drying the aerosol-generating substrate 30, first, the unbaked aerosol-generating substrate 30 is placed in the freezing area 460 in the freezing box 458 of the baking device 828, and the aerosol-generating substrate 30 is frozen to −55° C. to 0° C., and the aerosol-generating substrate 30 is completely crystallized and then taken out to obtain a crystallized aerosol-generating substrate 30. The aerosol-generating substrate 30 is then placed in the baking device 824, and the crystallized aerosol-generating substrate 30 is subjected to preliminary microwave baking by the method of the above embodiment, and the crystallized aerosol-generating substrate 30 is then dried. The aerosol-generating substrate 30 may be expanded under the action of microwaves and 10-60% of the moisture content in the crystallized aerosol-generating substrate 30 may be removed to obtain a semi-baked aerosol-generating substrate 30, and then the semi-baked aerosol-generating substrate 30 may be taken out and placed in the drying area 452 in the vacuum drying box 450 of the baking device 828 to bake the aerosol-generating substrate 30 according to the method of the above embodiment until the moisture content is 5-15% of the weight of the aerosol-generating substrate 30. In this way, a baked aerosol-generating substrate 30 may be obtained.

[0215] In this drying embodiment, before microwave baking, the aerosol-generating substrate 30 is first frozen, and then baked using a vacuum microwave baking method to remove a large amount of moisture from the aerosol-generating substrate 30, and then placed in a vacuum drying box for drying, which can greatly shorten the vacuum drying time and make the internal loose structure of the aerosol-generating substrate 30 more uniform, while simultaneously achieving the effect of insecticidal sterilization.

[0216] In the above embodiment, in the microwave baking process, violent movement of polar molecules occurs, so that heat is instantly generated inside the aerosol-generating substrate. Furthermore, vapor pressure is generated inside the aerosol-generating substrate, which creates a vapor pressure gradient inside the paste-like aerosol-generating substrate, causing the material of the paste-like aerosol-generating substrate to expand, and the expansion force of the gas causes structural denaturation of the polymeric substance in the paste-like aerosol-generating substrate 30 material.

[0217] The aerosol-generating substrate 30 obtained in the above-mentioned examples of drying the aerosol-generating substrate 30 has a soft structure and is porous and loose inside, so that its density is low, and the density distribution range is 0.10 to 0.90 g / cm. 3 It is.

[0218] There are many methods for baking materials, but the conventional heating methods (thermal conduction, convection, radiation) all start from the surface of the material and heat and bake the material from the outside to the inside. The present invention provides an embodiment of a method for manufacturing another aerosol-generating substrate. According to this manufacturing method, a metal material is added in the raw material mixing, and in the baking process of the aerosol-producing substrate, high-frequency induction technology is used to heat the metal material inside the aerosol-producing substrate, so that the aerosol-producing substrate is heated uniformly from the inside, and the baking process can be accelerated.

[0219] In this embodiment, a metal material is added to the raw material of the aerosol-generating substrate 30. In this way, when subjected to the action of high frequency in the subsequent high-frequency induction baking device, an induced current of the same frequency is formed on the surface of the metal material, and then heat is rapidly generated, so that the aerosol-generating substrate 30 is heated by the metal material inside, thereby achieving the baking effect.

[0220] In this embodiment, the method for producing the aerosol-generating substrate includes three steps: producing a paste-like material for the aerosol-generating substrate, producing the paste-like material into the shape of the aerosol-generating substrate, and baking the aerosol-generating substrate. Furthermore, in this embodiment, the method for producing the aerosol-generating product includes three steps: producing a paste-like material for the aerosol-generating substrate, a molding process for producing the paste-like material into the shape of the aerosol-generating substrate, and baking the semi-finished product of the aerosol-generating product. In the baking step of the semi-finished product of the aerosol-generating product, the unbaked aerosol-generating substrates 114, 120, 124, 128 may be placed in a baking device and baked before being placed in the packaging material 40. The unbaked aerosol-generating substrates 118, 112, 126, 130, 134 may be placed in a baking device and baked. Since the unbaked aerosol-generating substrates 118, 112, 126, 130, 134 are already wrapped in the tubular wrapping material 40, the space of the tubular wrapping material 40 that is not filled with the paste-like material may be filled with other assemblies, such as a filter assembly, a flavor assembly, a cooling assembly, or a susceptor assembly. After the aerosol-generating substrates 118, 112, 126, 130, and 134 are dried, It may be selectively loaded.

[0221] In this embodiment, the method for producing the paste material of the aerosol production base material is as follows. In the first step, 40-80 parts of the ground and mixed raw material, 10-20 parts of tobacco extract, 30-60 parts of aerosol generating agent, 10-30 parts of essence flavor, 1-5 parts of aerosol base forming agent, 1-3 parts of aerosol base swelling agent, 1-10 parts of aerosol sustained release agent, 30-50 parts of water, and 1-10 parts of metal material are mixed and stirred. When further stirred uniformly with a stirrer, the above-mentioned paste wet material is formed.

[0222] In the second step, after the preparation of the paste-like material for the aerosol-generating substrate 30 is completed, the paste-like material is molded into the aerosol-generating substrate 30. The molding method for the aerosol-generating substrate 30 of the present invention is the same as the molding method for the aerosol-generating substrate 30 in the above embodiment, and the aerosol-generating substrate 30 with a metal material is obtained. The molding method will be described with reference to the drawings in the above embodiment.

[0223] Please refer to Fig. 7. The paste-like material with the metal material is put into an aerosol-generating substrate forming device 800, and the aerosol-generating substrate containing the metal material is obtained in the same manner as in the above embodiment.

[0224] Please refer to Figure 8. The paste-like material with the metal material is put into an aerosol-generating substrate forming device 802, and an aerosol-generating substrate containing the metal material is obtained in the same manner as in the above embodiment.

[0225] See Figure 10. The paste-like material with the metal material is put into an aerosol-generating substrate forming device 804, and an aerosol-generating substrate containing the metal material is obtained in the same manner as in the above embodiment.

[0226] See Figure 11. The paste-like material with the metal material is put into an aerosol-generating substrate forming device 806, and an aerosol-generating substrate containing the metal material is obtained in the same manner as in the above embodiment.

[0227] See Figure 12. The paste-like material with the metal material is put into an aerosol-generating substrate forming device 808, and an aerosol-generating substrate containing the metal material is obtained in the same manner as in the above embodiment.

[0228] See Figure 14. The paste-like material with the metal material is fed into an aerosol-generating substrate forming device 810, and an aerosol-generating substrate containing the metal material is obtained in the same manner as in the above embodiment.

[0229] See Figure 16. The paste-like material with the metal material is put into an aerosol-generating substrate forming device 812, and an aerosol-generating substrate containing the metal material is obtained in the same manner as in the above embodiment.

[0230] See Figure 18. The paste-like material with the metal material is put into an aerosol-generating substrate forming device 814, and an aerosol-generating substrate containing the metal material is obtained in the same manner as in the above embodiment.

[0231] In the third step, after the paste-like material with metal material is manufactured into the aerosol-producing substrate 30, the corresponding baked aerosol-generating substrate can be obtained by using the same baking method as in the above embodiment of drying the aerosol-generating substrate 30.

[0232] Referring to Figure 25, Figure 25 is a structural schematic diagram of an aerosol-generating substrate baking apparatus 830. The present invention provides an embodiment of drying an aerosol-generating substrate 30, and the aerosol-generating substrate 30 with a metal material is baked using the aerosol-generating substrate baking apparatus 830.

[0233] The aerosol-generating substrate baking device 830 includes an inductor oven 468 and a high-frequency power supply 466. The high-frequency power supply 466 supplies high-frequency power to the inductor oven 468, and the power supply frequency is 100-500KHZ. The inductor oven 468 is an inductor wound with a hollow copper tube. When the high-frequency power supply is turned on, a high-frequency wave is generated from the inductor oven 466. Under the action of the high-frequency wave, an induced current of the same frequency is formed on the surface of the metal material inside the aerosol-generating substrate with the metal material, and heat is rapidly generated. Since the metal material is uniformly distributed inside the material, the material is uniformly heated inside, and a rapid baking effect is achieved.

[0234] The aerosol-generating substrate with the metal material to be baked is placed in inductor oven 468, the temperature of inductor oven 468 is set to 30 to 80°C, preferably 45 to 65°C, the power output from high frequency power supply 466 to inductor oven 468 is set to 0.8 to 4.0KW, preferably 1.0 to 2.5KW per kilogram of material, the baking time is set to 100 to 600 minutes, and when high frequency power supply 466 with a power frequency of 100 to 500KHZ is conducted to inductor oven 468, high frequency is generated from inductor oven 468, and under the action of the high frequency, an induced current of the same frequency is formed on the surface of the metal material in the aerosol-generating substrate with the metal material, and heat is rapidly generated.

[0235] In the baking process, the metal material in the aerosol-generating substrate is subjected to the action of high frequency waves in the inductor oven 468 to generate heat, which heats the aerosol-generating substrate internally, causing the leavening agent in the raw material of the aerosol-generating substrate to pyrolyze and generate gas, causing the paste-like aerosol-generating substrate to puff up, increase in volume, soften the volumetric structure, and form a porous, loose structure with uniform pores. The principle by which the leavening agent in the aerosol-generating substrate pyrolyzes and generates gas has been described in the above examples, and will not be repeated here.

[0236] During the baking process, a large amount of water contained in the raw materials of the aerosol-generating substrate evaporates, reducing the density and hardness of the aerosol-generating substrate and making it suitable for insertion into and heating in a heating device.

[0237] Finally, the aerosol producing substrate is baked until the moisture content is 5-15% of the weight of the aerosol producing substrate, thereby obtaining a baked aerosol producing substrate that can be heated and inhaled.

[0238] Furthermore, utilizing the principle that the boiling point of a liquid decreases under low pressure, the inductor oven 468 of the aerosol-generating substrate baking apparatus 830 may be evacuated to accelerate the baking process of the aerosol-generating substrate 30 with the metal material.

[0239] As can be seen from the above, by baking the aerosol-generating substrate 30 with the metal material using the high-frequency induction baking method by the aerosol-generating substrate baking device 830, the inside of the aerosol-producing substrate with the metal material can be uniformly heated, the baking efficiency is fast, the heating effect is improved, the material consistency is improved, and the porosity distribution is more uniform.

[0240] As shown in Fig. 26, the unbaked aerosol-generating substrate 130 is cut into aerosol-generating substrates 132 with tubular wrapping materials after baking. The tubular wrapping material of the aerosol-generating substrate 132 with tubular wrapping material has some empty tubes in which other assemblies can be inserted.

[0241] As shown in Fig. 27, the unbaked aerosol-generating substrate 134 is cut into aerosol-generating substrates 136 with tubular wrapping materials after baking. The tubular wrapping material of the aerosol-generating substrate 136 with tubular wrapping material has some empty tubes in which other assemblies can be inserted.

[0242] The aerosol-generating substrate after baking obtained in the above examples has the characteristics of low hardness, a porous sponge-like interior, low moisture content, and being a columnar integrated substrate. Therefore, the aerosol-generating substrate 30, the aerosol-generating substrate 132 with a tubular wrapping material, and the aerosol-generating substrate 136 with a tubular wrapping material can be inserted into the heating part of a heating appliance. The heat generated by heating with the heating part of the heating appliance has good heat transfer effect in the aerosol-generating substrate 30, the aerosol-generating substrate 132 with a tubular wrapping material, and the aerosol-generating substrate 136 with a tubular wrapping material, and is heated uniformly. The aerosol generated by heating the aerosol-generating substrate 30, the aerosol-generating substrate 132 with a tubular wrapping material, and the aerosol-generating substrate 136 with a tubular wrapping material by the heating appliance can pass through the internal porous voids and has an appropriate suction resistance, so that the temperature of the aerosol inhaled into a person's mouth is moderate, making it suitable for inhalation into the mouth by consumers.

[0243] The aerosol-generating substrate 30, the aerosol-generating substrate 132 with a tubular wrapping material, and the aerosol-generating substrate 136 with a tubular wrapping material obtained by the above-mentioned baking methods have a soft structure, a porous and loose interior, and contain metal materials in their raw materials, which makes the aerosol-generating substrate heavy. However, excluding the metal material components, the density distribution range of the aerosol-generating substrate is 0.10 to 0.90 g / cm. 3 It is.

[0244] The metal material added to the aerosol-generating substrate 30, the aerosol-generating substrate 132 with a tubular wrapping material, and the aerosol-generating substrate 136 with a tubular wrapping material may be a magnetic material, or may be a metal material and a magnetic material. The paste-like molding method, baking method, baking principle, and the effects thereof, as well as the structure and suction effect of the formed aerosol-generating substrate 30, the aerosol-generating substrate 132 with a tubular wrapping material, and the aerosol-generating substrate 136 with a tubular wrapping material, etc., are described in detail below. The aerosol-generating substrate obtained by the above-mentioned embodiment, the aerosol-generating substrate with the tubular wrapping material, It's the same.

[0245] The aerosol-generating product containing a metal material, the aerosol-generating product containing a magnetic material, and the aerosol-generating product containing a metal material and a magnetic material can generate heat by themselves under the action of a changing magnetic field, so that the aerosol-generating substrate 30, the aerosol-generating substrate 132 with a tubular wrapping material, and the aerosol-generating substrate 136 with a tubular wrapping material are heated to generate aerosol. The aerosol-generating product may be heated and sucked using an electromagnetic heating device, which eliminates the need to insert the aerosol-generating product into the heating part of the heating device to be heated, and the aerosol-generating substrate 30 is not left on the heating part when the aerosol-generating product is removed, making it easy to clean the heating device. At the same time, when the aerosol-generating product uses electromagnetic induction heating, the electromagnetic susceptor generates heat uniformly, so that the aerosol-generating substrate 30, the aerosol-generating substrate 132 with a tubular wrapping material, and the aerosol-generating substrate 136 with a tubular wrapping material are heated uniformly, achieving a good suction effect.

[0246] As a method for baking the aerosol-generating substrate, in addition to the above-mentioned drying examples, other baking machines such as a rotary baking machine, a drum dryer, a tunnel microwave dryer, a tunnel baking machine, a mesh belt tunnel furnace, a vacuum rake dryer, a double cone vacuum dryer, and a low-temperature single cone vacuum dryer may be used for baking, and the aerosol substrate 30 can be expanded to have a loose structure by adding a vacuum or the like at an appropriate temperature and time. There are various types of baking methods, and not all of them are listed here, but any baking method that can achieve the required baking purpose can be used.

[0247] The aerosol-generating substrate obtained in the above example has a crystal block and plant The fiber filaments include plant The fiber filaments are distributed non-uniformly among the crystal blocks. The crystal blocks include a plant raw material powder and an aerosol substrate forming agent, and are formed during a molding and baking process of the aerosol-generating substrate. The crystal blocks have irregular shapes and sizes, and the crystal blocks are bonded to each other to form the integral aerosol-generating substrate. When a packaging material is further included during the molding process of the aerosol-generating substrate, the crystal blocks and / or vegetable fiber filaments The portion of the aerosol-generating base material that comes into contact with the packaging material also adheres to the packaging material. Between the crystal blocks, there are voids that are arranged unevenly and have irregular sizes, and the porosity between the crystal blocks is 45% to 70%, so that a porous and loose structure is formed. The liquid raw materials in the aerosol-generating base material, such as the aerosol-generating agent, tobacco extract, essence flavor, and water, are absorbed into the crystal blocks and the plant Glycerin is a commonly used aerosol generating agent, and when glycerin is used as an aerosol generating agent, it penetrates into the interior of the fiber filaments. plant It penetrates into the interior of the fiber filaments.

[0248] The inside of the aerosol-generating substrate contains the crystal block and the plantThe crystal blocks contain fiber filaments and, after baking, have a moisture content of 3% to 15%. The total weight of the crystal blocks accounts for at least 10% of the total weight of the aerosol-generating substrate.

[0249] When the aerosol-generating substrate is baked, the water evaporates and the paste in the aerosol-generating substrate expands during the drying process, resulting in an aerosol-generating substrate with a low density, the density range of which, excluding the packaging material and metal material, is 0.1 g / ml to 0.9 g / ml.

[0250] The aerosol-generating substrate after baking obtained in the above examples has a porous and loose interior, and the internal voids allow the aerosol generated by heating to pass through, but in the end, the voids are relatively small, and the aerosol-generating substrate does not have a through hole from one end to the other, and when not heated, the aerosol-generating substrate has a large resistance to inhalation, which is larger than that of a conventional heated non-combustion cigarette. Also, in the aerosol-generating substrate after baking obtained in the above examples, the aerosol generating agent in the aerosol-generating substrate accounts for 1% to 12% of the weight of the aerosol-generating substrate.

[0251] The draw resistance test was carried out using a smoking machine according to the conventional analysis device-definition and standard conditions for e-cigarette aerosol generation and collection No. 81 recommended by the International Cooperation Centre for Scientific Research Relative to Tobacco (CORESTA). The test conditions were: draw environment temperature 22°C ± 2°C, relative humidity 60% ± 5%, maximum draw speed 18.5ml / s ± 1ml / s, draw frequency 30s ± 0.5s, draw volume 55ml ± 0.3ml, draw duration 3s ± 0.1s, draw waveform square wave, and smoke machine pressure drop 300Pa or less. When the draw resistance of conventional cigarettes and e-cigarettes was tested under the above conditions, the majority of the draw resistances were less than 1.0Kpa, even less than 0.8KPa or less than 0.5KPa, and draw resistances of 2.0KPa or more were extremely rare. When a packaging material is added to the aerosol-generating substrate obtained in the above examples, and then the substrate is heated and inhaled directly, the inhalation resistance is generally greater than that of conventional cigarettes and electronic cigarettes, of which 50% or more have an inhalation resistance exceeding 2.0 kpa, and 70% or more have an inhalation resistance exceeding 1.0 kpa, and may exceed 2.5 KPa, may exceed 3.0 KPa, or may exceed 4.0 KPa, with the inhalation resistance ranging from 1.0 KPa to 5.0 KPa.

[0252] When the aerosol-generating substrate is heated and inhaled, the inhalation resistance is large the first time and may exceed 1.5 KPa, 2.0 KPa, or 3.0 KPa. If inhalation is continued after the first time, the inhalation resistance gradually decreases, and after the third or fourth inhalation, the inhalation resistance decreases to about 1.0 KPa, which is relatively suitable for inhalation by a smoker.

The aerosol-generating product 100 includes an aerosol-generating substrate 30 and a wrapping material 32 that wraps the aerosol-generating substrate 30. When the aerosol-generating substrate 30 is heated, an aerosol is generated and is inhaled by a smoker.

The same assemblies as those in the above embodiment will be described briefly, and only the filter assembly 34 will be described in detail in this embodiment. The filter assembly 34 is a porous sponge-like tissue that serves to filter the aerosol generated from the aerosol-generating substrate 30 and filter out the microparticles contained in the aerosol. At the same time, the filter assembly 34 can be embedded with flavor elements, such as flavor balls or flavor strips. In this way, when the aerosol passes through the filter assembly 34, the flavor elements embedded in the filter assembly 34 can also be mixed, thereby increasing the flavor of the aerosol.

[0255] The filter assembly 34 may be a porous sponge-like rod that functions to filter aerosols, and the inside of the filter assembly 34 may be hollow. The porous sponge-like rod may be a foamed material obtained by a chemical reaction, and the foamed material may be polyethylene terephthalate (PET), polylactide, polyhydroxyalkanoate, acetate fiber, etc., and the filter assembly 34 may be a porous sponge-like rod with a hollow inside.

[0256] The filter assembly 34 may also be formed from one or more hollow porous sponge rods and porous sponge rods wrapped in a sheet material.

[0257] In addition, a flavoring assembly may be embedded inside the filter assembly 34, the flavoring assembly being in the form of a flavoring ball or a flavoring strip, the flavoring ball may be a porous ceramic ball having a flavoring adsorbed thereon, and when the aerosol-generating product is inserted into the heating part of a heating appliance and heated to inhale the aerosol, the flavoring is inhaled into the smoker's mouth together with the aerosol, the flavoring ball may be a capsule having a flavoring encapsulated inside the capsule, and when the aerosol-generating product is inserted into the heating part of a heating appliance and heated to inhale the aerosol, when the capsule is broken, the flavoring inside the capsule can be inhaled into the smoker's mouth together with the aerosol, and by sealing the flavoring in the capsule, the flavoring does not become diluted due to evaporation, making the flavoring ball suitable for long-term storage.

When an aerosol-generating product is inserted into a heating part of a heating appliance and heated to inhale the aerosol, when the capsule is broken, the flavor in the capsule can be inhaled into the smoker's mouth together with the aerosol. A flavor is generally volatile, and the advantage of using a capsule to enclose the flavor in the flavor spheres 142 is that the outer capsule is a sealed body, and the flavor can be stored for a long time without becoming diluted due to volatilization.

[0261] Of course, in the present embodiment of the filter assembly, more than one scented sphere may be embedded within the filter material 140, and the scented spheres may be connected within the filter material 140 or spaced apart.

[0331] Referring to Fig. 54, Fig. 54 is a structural schematic diagram of an aerosol-generating product 108 according to another embodiment of the present invention, the aerosol-generating product 108 including an aerosol-generating substrate 30 and a packaging material 32 that encases the aerosol-generating substrate 30, the aerosol-generating substrate 30 including a susceptor assembly 39. The susceptor assembly 39 includes a susceptor 162 and a base 160, the susceptor 162 being attached to the base 160. The susceptor 162 of the susceptor assembly 39 is enclosed inside the aerosol-generating substrate 30, and the base 160 has one end surface that contacts the end surface of the aerosol-generating substrate 30 and the other end surface that is the outer end surface of the aerosol-generating product 108. The susceptor assembly 39 and the aerosol-generating substrate 30 are enclosed inside by the packaging material 32. The base 160 has a ventilation function, and gas can pass from the base 160 to the end face of the aerosol substrate 30 and then flow through the internal gap of the aerosol-generating substrate 30 .

[0332] The base 160 may have a triangular, polygonal, circular or irregular cross section along the longitudinal direction of the aerosol-generating product 108, and the base 160 may have a through hole through which air can pass, and the through hole may be provided on the inside or outer circumferential surface of the base, and the shape of the through hole may be any shape such as a circle, an ellipse, a square, a triangle, a diamond, a circular arc, etc. In this embodiment, the material of the base 160 may be a material that can withstand a high temperature of 80° C. or more, and the material of the base 160 may be a ceramic material, a silica gel material, a glass, a plastic, a wood fiber, a gypsum, a gel, a silicon carbide, a high-temperature rubber, an acetate fiber, a polyethylene terephthalate, a polylactide, a polyhydroxyalkanoate, a metal material, a paper, a tin foil, an aluminum foil, etc.

[0333] The longitudinal direction of the aerosol-generating product 108 is the A-A' direction in the figure, and the direction perpendicular to the longitudinal direction is the transverse direction of the aerosol-generating product 108. In this embodiment, in order to meet different usage needs, one or more susceptors 162 made of the same or different materials are arranged in the aerosol-generating substrate 30 in a longitudinal direction. The susceptors 162 are wrapped by the aerosol-generating substrate 30 and are in thermal contact with it. The susceptors 162 sense the occurrence of hysteresis loss and / or eddy current in the changing electromagnetic field in the corresponding induction heating device, and further generate heat, and convert the electromagnetic energy into thermal energy, so that the aerosol-generating substrate 30 is heated to generate aerosol. Of course, in other embodiments, one or more susceptors 162 made of the same or different materials may be arranged in the aerosol-generating substrate 30 in a transverse direction or other directions, and all are within the scope of the present invention of arranging susceptors in the aerosol-generating substrate 30, as long as the same thermal energy conversion effect can be achieved.

[0334] The susceptor 162 is any material that generates heat by itself under the action of a changing magnetic field to generate an aerosol on the aerosol-generating substrate 30, and preferred materials include metal, carbon, or silicon. The metal material may be iron, aluminum, copper, nickel, cobalt, titanium, and alloy materials thereof, one application of the carbon induction heating material may be carbon fiber reinforced composite material, graphite, and one application of the silicon induction heating material may be a fully dielectric silicon metamaterial.

[0335] One preferred metallic material for the susceptor 162 is a ferromagnetic material, such as a ferromagnetic alloy, an iron-nickel alloy, an iron-nickel fixed expansion alloy, ferritic iron, or ferromagnetic steel or stainless steel, or other ferromagnetic material.

[0336] One of the preferred metallic materials for the susceptor 162 is a soft magnetic alloy, such as magnetic pure iron, iron silicon alloy, iron aluminum alloy, iron silicon aluminum alloy, iron nickel alloy, iron cobalt alloy, ultrafine crystalline soft magnetic alloy.

[0337] One of the preferred series of iron-nickel alloys is the iron-nickel fixed expansion alloy, which is a series of fixed expansion alloys obtained by adjusting the nickel content, which are compatible with soft glasses and ceramics having different expansion coefficients within a certain temperature range, and whose expansion coefficients and Curie points increase with increasing nickel content.

[0338] One of the preferred alloys of the iron-nickel alloy is one of the nickel-iron mu-metal or permalloys.

[0339] One of the preferred metal materials of the susceptor 162 is nickel alloy, especially Fe-Ni-Cr alloy. Fe-Ni-Cr alloy has good corrosion prevention performance. One of the preferred materials of nickel-based alloy is Phytherm 30, Phytherm 50, Phytherm 120, Phytherm 230, Phytherm 260, etc.

[0340] One preferred metallic material for the susceptor 162 is an Fe-Ni-Cu-X alloy, where X is one or more elements selected from Cr, Mo, Mn, Si, Al, W, Nb, V, and Ti.

[0341] Another preferred metal material for the susceptor 162 may be an aluminum or aluminum alloy material.

[0342] The material of the susceptor 162 may further include a suitable non-magnetic, particularly paramagnetic, conductive material, such as aluminum (Al) or an aluminum alloy material, in which the induction heating occurs only by electrical resistance heating due to eddy currents.

[0343] The material of the susceptor 162 may include, for example, a non-conductive ferrimagnetic material, such as a non-conductive ferrimagnetic ceramic. Under these circumstances, heat is generated only by hysteresis losses.

[0344] The susceptor 162 may be heated to a temperature of about 100°C to about 500°C, particularly about 150°C to about 400°C, and preferably about 250°C to about 350°C.

[0345] The Curie temperature of the susceptor 162 is less than 500°C, preferably less than 400°C, and more preferably about 150 to 380°C.

[0346] Preferred susceptors 162 are strip-shaped, lever-shaped, pin-shaped, cone-shaped, granular, rod-shaped, hollow tube-shaped, sheet-shaped, blade-shaped, spiral-shaped, spherical, T-shaped, cross-shaped, triangular, elliptical, conical, square, pentagonal, hexagonal, polygonal, and irregular contour shapes. The material of the susceptor 162 may have a length dimension of 3 mm to 18 mm and a width dimension of 1 mm to 7 mm. When the material of the susceptor 162 is sheet-shaped, the thickness of the susceptor material may be 0.01 mm to 3 mm, when the material of the susceptor 162 is rod-shaped, the outer diameter dimension of s may be 1 mm to 3 mm, when the material of the susceptor 162 is granular, the outer diameter dimension may be 0.01 mm to 3.0 mm. The surface area of ​​the susceptor material may be 0.1 mm 2 ~150mm 2 It is.

[0347] It will be appreciated that there may be one or more susceptors within the aerosol-generating substrate 30, and that they may be of the same or different materials. The susceptors may be in contact with one another, e.g., pressed together, one susceptor may be covered by an outer layer of another susceptor, or the susceptors may be spaced apart, and the outer shapes of the different susceptors may be the same or different shapes, e.g., one susceptor may be in sheet form and another susceptor may be in granular, lever, or sheet form of different sizes or shapes, etc.

[0348] The surface of the susceptor 162 may further include an additional protective material, such as a protective ceramic layer, a protective Teflon coating, a protective glass layer, or may be electroplated with an inert metal protective layer, such as, for example, a nickel layer electroplated onto the surface of the ferrite.

[0349] The susceptor 162 may have different Curie temperatures if it is made of a number of different materials. The susceptors with different Curie temperatures are called heating susceptors and temperature-control susceptors, respectively. The heating susceptor has a heating Curie temperature that heats the susceptor to a certain temperature, and the temperature-control susceptor has a temperature-control Curie temperature that controls the susceptor to a certain temperature range. When the temperature-control susceptor is heated to the temperature-control Curie temperature, its magnetic performance changes and the material of the susceptor reversibly changes from a ferromagnetic phase to a paramagnetic phase. In the induction heating process of the aerosol-generating substrate, the phase change of the material of the temperature-control susceptor can be detected online, so that the induction heating is automatically stopped. Therefore, even if the heating Curie temperature of the heating susceptor is higher than the temperature-control Curie temperature, the device automatically stops the induction heating, so that the heating by the heating susceptor is also stopped, and local overheating and burning of the aerosol-generating substrate is prevented. After induction heating is stopped, when the temperature-controlled susceptor cools down to a temperature lower than the temperature-controlled Curie temperature, the temperature-controlled susceptor regains its strong magnetic performance, and such phase change is detected online to activate induction heating again.

[0350] Naturally, when there is only one type of susceptor, the heating Curie temperature becomes the temperature control Curie temperature, and the susceptor has both a heating function and a temperature control function. Naturally, when the heating susceptor and the temperature control susceptor are separate, and there is a sufficient temperature difference between the heating Curie temperature and the temperature control Curie temperature, the heating temperature can be effectively controlled to prevent the aerosol-generating substrate from being locally overheated or scorched.

[0351] During the heating process of the susceptor 162, the electrical resistance of the susceptor increases or decreases. When selecting different material susceptors, materials with the same electrical resistance temperature coefficient may be selected, or materials with different electrical resistance temperature coefficients may be selected, both of which can achieve the same effect.

[0352] The susceptor 162 may be disposed near the aerosol-generating substrate, may be disposed around the aerosol-generating substrate 30, or may be disposed inside the aerosol-generating substrate 30. When the susceptor is at least partially in contact with the aerosol-generating substrate, and the susceptor is completely surrounded by and in contact with the aerosol-generating substrate, heat transfer is optimal and the heating effect is best.

[0353] In one embodiment of the present invention, the inside of the aerosol-generating substrate 30 is porous and loose, and the internal voids are small, which has a good thermal conductivity effect and allows for uniform heating. When combined with the susceptor assembly 39, the effects of faster and more uniform heating can be achieved.

[0354] 55, which is an assembly schematic diagram of an aerosol-generating product 194, the present invention provides another embodiment of an assembly of an aerosol-generating product, and the aerosol-generating product 194 includes a baked aerosol-generating substrate 130, a filter assembly 34, and a susceptor assembly 80.

[0357] In this assembly embodiment, the filter assembly 34 may be any of the filter assembly embodiments described above, the flavor assembly 36 may be any of the flavor assembly embodiments described above, and the cooling assembly 38 may be any of the cooling assembly embodiments described above.

[0358] 56, which is an assembly schematic diagram of an aerosol-generating product 196, the present invention provides another embodiment of an assembly of an aerosol-generating product, the aerosol-generating product 196 including a baked aerosol-generating substrate 110, a tubular wrapping material 40, a filter assembly 34 and a susceptor assembly 80. The susceptor assembly 80 is inserted into the inside of the aerosol-generating substrate 110, and then the aerosol-generating substrate 110 with the susceptor assembly 80 attached thereto is inserted into the left side of the tubular wrapping material 40, the outer end surface of the base of the susceptor assembly 80 is made flush with the end surface of the tubular wrapping material 40, and the filter assembly 34 is inserted into the right side of the tubular wrapping material 40, thereby obtaining the aerosol-generating product 196.

[0359] In this assembled embodiment, the baked aerosol-generating substrate 110 can be replaced with any of the other baked aerosol-generating substrates 30 described above, such as, for example, aerosol-generating substrate 112, aerosol-generating substrate 114, aerosol-generating substrate 116, aerosol-generating substrate 120, aerosol-generating substrate 124 or aerosol-generating substrate 128, to achieve a similar smoking effect using the aerosol-generating substrates described above.

[0360] In this assembly embodiment, the aerosol-generating product may be loaded into the flavor assembly 36 and / or the cooling assembly 38 before being loaded into the filter assembly 34 .

[0361] In this assembly embodiment, the filter assembly 34 may be any of the filter assembly embodiments described above, the flavor assembly 36 may be any of the flavor assembly embodiments described above, and the cooling assembly 38 may be any of the cooling assembly embodiments described above.

[0362] 57, which is a schematic assembly diagram of an aerosol-generating product 198, the present invention provides another embodiment of an aerosol-generating product, in which the aerosol-generating product 198 includes a baked aerosol-generating substrate 110, a sheet wrapping material 42, a filter assembly 34, and a susceptor assembly 80. The susceptor assembly 80 is inserted into the aerosol-generating substrate 110, and then the aerosol-generating substrate 110, the susceptor assembly 80, and the filter assembly 34 are wrapped in a rod shape with the sheet wrapping material 42 to obtain the aerosol-generating product 198.

[0363] In this assembled embodiment, the baked aerosol-generating substrate 110 can be replaced with any of the other baked aerosol-generating substrates 30 described above, such as aerosol-generating substrate 112, aerosol-generating substrate 114, aerosol-generating substrate 116, aerosol-generating substrate 120, aerosol-generating substrate 124 or aerosol-generating substrate 128, to achieve a similar smoking effect using the aerosol-generating substrates described above.

[0364] In this assembly embodiment, the aerosol-generating product may be loaded into the flavor assembly 36 and / or the cooling assembly 38 before being loaded into the filter assembly 34 .

[0365] In this assembly embodiment, the filter assembly 34 may be any of the filter assembly embodiments described above, the flavor assembly 36 may be any of the flavor assembly embodiments described above, and the cooling assembly 38 may be any of the cooling assembly embodiments described above.

[0366] As shown in Figure 58, in the above embodiment, the susceptor assembly includes only a susceptor 162, and the length of the susceptor 162 is shorter than that of the aerosol-generating substrate 30. When the susceptor 162 is inserted into the inside of the aerosol-generating substrate 30 from the end opening of the aerosol-generating substrate 30, a notch 164 is left at the position where the susceptor 162 passes through the end opening of the aerosol-generating substrate 30, and the shape of the notch 164 is the same as the maximum cross-section of the susceptor 162 in the same direction. The cross-section of the notch 164 may have a different shape, and may be a square, rectangular, quadrilateral, polygonal, circular, elliptical, diamond, triangular or irregular shape, and in this embodiment, a rectangle is taken as an example. The depth of the notch 164 occupies 10% to 70% of the length of the aerosol-generating substrate 30, the cross-sectional surface area of ​​the notch 164 occupies 1% to 20% of the cross-sectional surface area of ​​the aerosol-generating substrate 30 and the maximum dimension of the notch 164 is equal to or smaller than the outer diameter of the aerosol-generating substrate. Preferably, when the length of the aerosol-generating substrate 30 is 12 to 15 mm, the depth of the notch 164 is 1.2 mm to 10.5 mm. The notch 164 can increase the fluidity of air and reduce the resistance during suction when the aerosol-generating substrate 30 is heated and suctioned.

[0367] In practical applications, at least one or more notches 164 may be formed by disposing one or more of the susceptors 162 inside the aerosol-generating substrate 30 at the same or different positions along the edge surface of the aerosol-generating substrate 30.

[0368] In order to make the aerosol generated during the process of being heated and inhaled by the heating assembly of the heater more pleasant to taste and to reduce its unpleasant taste, the aerosol-generating product after assembly can also be aged using high-frequency induction.

[0369] The plant raw material of the aerosol-generating substrate 30 undergoes natural fermentation or fermentation by fermentation enzymes, through which the polymer structure inside the plant raw material is decomposed into low molecular structures, but it is not possible to completely decompose all of the polymer structures inside the plant raw material into low molecular structures. In order to further decompose the polymer structures inside the plant raw material, the aerosol-generating product can be subjected to high-frequency induction aging after assembly is completed, so that the polymer structures inside the aerosol-generating product are further decomposed and the purpose of aging the aerosol-generating product is achieved.

[0370] The plant raw material of the aerosol-generating substrate 30 is composed of groups with large molecular structures, and the taste of the polymer structure itself is relatively strong. It is difficult for the essence flavoring to mask the taste of the polymer itself. For example, the protein content in tea leaves reaches 21-28%, which causes a pungent taste during the heating process, a strong irritation, an increased bitterness, and an unpleasant protein odor.

[0371] By using high frequency radiation, it is possible to break down proteins and other substances in the raw materials into other low molecular weight substances. For example, tea leaves contain tea polyphenols, tea pigments, tea polysaccharides, tea saponins, proteins, amino acids, alkaloids, minerals, catechins, caffeine, minerals and other substances which have large molecular structures and the inherent flavor of the plant raw materials is affected by these polymer structural groups. During the seasoning process of the raw materials, it becomes difficult for the flavoring agent to mask the flavor formed by extracting the polymer structure of the raw materials themselves.

[0372] 59, which is a structural schematic diagram of high-frequency induction aging device 840, includes inductor 470 and high-frequency power supply 472. Inductor 470 is a high-frequency inductor wound with a hollow copper tube, and when high-frequency power output from high-frequency power supply 472 is conducted, it becomes possible to generate high frequency, and high-frequency power supply 472 supplies high-frequency power of a frequency of 500 KHz to 10 MHz to inductor 470.

[0373] When the aerosol-generating product is placed in inductor 470 and high-frequency power output from high-frequency power source 472 is conducted to inductor 470, high-frequency power is generated from inductor 470, and the induction time is set to 10 to 180 s.

[0374] Under the action of the high frequency generated by the inductor 470, the polymers in the plant raw materials of the aerosol-generating substrate 30 of the aerosol-generating product absorb the high frequency energy and then decompose into low molecular structures, so that the flavor of the raw materials themselves disappears or is reduced, and the purpose of aging the aroma of the cigarettes is achieved.

[0375] The use of radio frequency baking in the drying embodiment of the aerosol-generating substrate 30 according to the present invention has many advantages.

[0376] First, the heating is rapid and efficient: when the aerosol-generating substrate 30 with the metal material is placed in the inductor oven 468 and the high frequency power is turned on to start baking, the metal material inside the aerosol-generating substrate 30 is subjected to the action of the high frequency and immediately generates heat, so that the inside and outside of the aerosol-generating substrate 30 instantly reach the heating temperature.

[0377] Second, the heating is uniform. The uniform distribution of the metal material inside the aerosol-generating substrate 30 prevents the simultaneous generation of heat energy on the surface and inside of the aerosol-generating substrate 30, which results in the phenomenon that the outside is burnt while the inside is raw. As the moisture on the surface of the aerosol-generating substrate 30 continues to evaporate, the temperature of the surface of the aerosol-generating substrate 30 becomes slightly lower than the temperature of the inner layer, forming a temperature gradient from the inside to the outside, the direction of which coincides with both the direction of vapor pressure transfer and the direction of heat transfer generated during the heating process. According to the theory of drying of materials, such a heating state is extremely favorable for drying the material.

[0378] Thirdly, the thermal inertia is small, the heating is timely, and it is easy to control. The energy output from the high frequency is immediately absorbed by the metal material in the aerosol-generating substrate 30 to heat it, and by controlling the power of the high frequency power source, it is possible to realize immediate heating or immediate stopping, and there is no preheating process.

[0379] Fourth, the high frequency has the effect of killing insects and sterilizing. Under the action of the high frequency microwave in the inductor oven 468 of the aerosol-generating substrate baking device 830, the aerosol-producing substrate 30 can kill the pests and bacteria in the aerosol-producing substrate, thereby achieving the effect of killing insects and sterilizing.

[0380] If the aerosol-generating product with the electromagnetic susceptor is heated using an electromagnetic heating device, the aerosol-generating product does not need to be inserted into the heating part of the heating device for heating, so that when the aerosol-generating product is removed, the aerosol-generating substrate 30 does not remain on the heating part, making it easy to clean the heating device. At the same time, when heating is performed using the electromagnetic induction method, the electromagnetic susceptor generates heat uniformly, so that the aerosol-generating substrate 30 is heated uniformly, thereby achieving a good smoking effect.

[0381] In summary, the aerosol-generating product of the present invention is an integrated porous and loose aerosol-generating substrate, in which crystal block material and fiber filaments coexist, and between the crystal blocks there are gaps through which the aerosol generated by heating can pass, and the gaps between the crystal blocks are arranged in a spatially non-uniform state, the moisture content of the aerosol-generating substrate is low, the moisture content of the aerosol generated by heating is low, the temperature of the aerosol is low, and the phenomenon of the mouth becoming hot enough to hurt when inhaled by a smoker does not occur even without cooling. When the aerosol-generating product is heated by inserting the heating part of a heating tool, the insertion force is small and the heat conduction effect is good regardless of the insertion direction, the temperature of the generated aerosol is suitable for inhalation into the mouth of a smoker, the inhalation resistance is good, and a good smoking effect can be achieved, and the product can also be adapted to heating and inhalation by an induction heating device.

[0382] The present invention has been disclosed above, but the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so the protection scope of the present invention should be in accordance with the scope defined in the claims.
