[0002] The present disclosure relates to the technical field of aerosol-generating substrates, and in particular to a method and equipment for manufacturing an aerosol-generating product. Background Art

[0003] The aerosol-generating substrate can form an aerosol by ignition or by heating without combustion. In the heat-without-combustion aerosol-generating substrate, the aerosol-generating substrate is heated by an external heat source to a degree sufficient to emit an aerosol, but does not burn. The aerosol-generating substrate is loaded with a smoke agent, and upon use, the smoke agent is released by heating the aerosol-generating substrate to form an aerosol.

[0024] In some embodiments, the material includes a solid raw material and a liquid raw material, and the feeding of the material includes:

On the one hand, by controlling the moisture content of the mixture and the moisture content of the extruded matrix formed by extrusion, the extruded matrix can be dried without additional drying equipment, thereby allowing the extruded matrix to be shaped and have a certain hardness for subsequent steps. This shortens the process flow for preparing the aerosol-generating product, solves the problems of long drying time and high energy consumption, thereby improving production efficiency and reducing production costs. On the other hand, the extruded matrix formed by extrusion does not need to be dried at high temperatures, which improves the loss of effective substances caused by the extruded matrix during the drying process, improves the quality of the extruded matrix, and improves the uniformity and stability of the extruded matrix.

[0058] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of the present disclosure can be combined with each other, and the detailed description in the specific implementation methods should be understood as an explanation of the purpose of the present disclosure and should not be regarded as an improper limitation on the present disclosure.

[0059] In this disclosure, the temperature unit "°C" stands for degrees Celsius. The pressure unit "bar" stands for bar. The unit "μm" stands for micrometer. The viscosity unit "pa.s" stands for Pascal-second. The unit "pa" stands for Pascal.

[0060] It should be noted that the aerosol-generating article includes an aerosol-generating substrate, may include a functional segment, or may not include a functional segment.

[0061] The aerosol-generating substrate is used to generate an aerosol upon heating. For example, the aerosol-generating substrate can be used to generate aerosols by heating and combustion. Alternatively, the aerosol-generating substrate can be used to generate aerosols by heating without combustion. That is, the aerosol-generating substrate is heated to a temperature below its ignition point to generate the aerosol. The aerosol-generating substrate does not burn during the aerosol generation process.

[0062] The functional section is arranged at one end of the aerosol generating substrate in the longitudinal direction, and includes a filter section for filtering aerosol. The filter section is used to filter aerosol generated by the aerosol generating substrate.

[0063] Of course, in some embodiments, the aerosol-generating article may not include a functional segment.

[0064] Aerosol-generating articles are designed to allow users to inhale aerosols generated by an aerosol-generating substrate. For example, users can hold a filter segment in their mouth and inhale the filtered aerosol. The aerosol generated by the aerosol-generating substrate is transported to the filter segment under the influence of negative pressure.

[0065] The aerosol-generating article is used in conjunction with an aerosol-generating device having a heating component. Specifically, the heating component heats and atomizes an aerosol-generating substrate to generate an aerosol.

[0066] There are various heating methods for the heating assembly, including, for example, central heating, peripheral heating, and / or bottom heating. Central heating involves inserting the heating assembly into the aerosol-generating article to heat it from the inside out. Peripheral heating involves placing the heating assembly around the periphery of the aerosol-generating article to heat it from the outside in. Bottom heating involves placing the heating assembly at the bottom of the aerosol-generating article, heating the air first, and then heating the aerosol-generating article from the bottom up.

[0067] It should be noted that the bottom of the aerosol-generating article is the end thereof that is away from the functional section in the longitudinal direction.

[0068] The heating methods of the heating component include but are not limited to resistance heating, electromagnetic heating, infrared heating, microwave heating or laser heating.

[0069] In some embodiments, the functional segment may only be provided with a filtering segment.

[0070] In other embodiments, the functional section further includes a cooling section, located between the filtration section and the aerosol-generating matrix. The cooling section is used to cool the aerosol before filtering it by the filtration section. The cooling section can reduce the "burning mouth" phenomenon when the user inhales the aerosol.

[0071] The cooling materials used in the cooling section include but are not limited to one or more combinations of PE (polyethylene), PLA (Polylactic Acid), PBAT (Polybutylene Adipate Terephthalate), PP (Polypropylene), acetate fiber, acrylic fiber and the like.

[0072] The filter material used in the filter section includes but is not limited to one or more combinations of PE (polyethylene), PLA (Polylactic Acid), PBAT (Polybutylene Adipate Terephthalate), PP (Polypropylene), acetate fiber, acrylic fiber and the like.

[0073] The materials of the cooling section and the filtering section can be the same or different.

[0074] In the related art, in the aerosol generation matrix production process, the slurry moisture content is relatively high (papermaking method>90%, thick pulp method>70%, roller pressing method>20%), and there is a high-intensity drying link in the subsequent process, which is not conducive to the retention of aroma components and effective substances in the extruded matrix 200. In addition, the aerosol generation matrix in the related art is a sheet structure, and there are problems such as uneven drying, large losses, and high processing costs during the processing. There are long processes, many intermediate products from raw materials to finished products, low production efficiency, high production costs, and the loss of effective substances is easy to cause during the manufacturing process. In addition, the sheet aerosol matrix also needs secondary processing such as winding, unwinding, shredding or embossing, which has high losses, complex process technology, and high equipment investment. In particular, the papermaking method consumes a lot of energy during the processing and pollutes the environment.

[0075] To address the above-mentioned issues, the present disclosure provides a method for manufacturing an aerosol-generating product. FIG1 is a flow chart of a method for manufacturing an aerosol-generating product according to an embodiment of the present disclosure. As shown in the figure, the method for manufacturing an aerosol-generating product includes the following steps S101 to S104:

[0076] S101, feeding the materials to form a mixed material with a water content of 2-20%.

[0077] The water content of the mixture 200' is, for example, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 13%, 14%, 15%, 16%, 17%, 18%, 19% or 20%, etc.

[0078] Here, the mixed material 200 ′ having a water content of 2 to 20% means that the water content in the mixed material 200 ′ is 2 to 20% of the total weight of the mixed material 200 ′.

[0079] The moisture in the mixed material 200 ′ is mainly composed of the moisture in the solid module raw materials, and no water is added or a small amount of water is added as needed.

[0080] By controlling the water content of the mixed material 200 ′ to be 2-20%, that is, by controlling the mixed material 200 ′ to be at a lower water content, it is advantageous to form the extruded matrix 200 with a lower water content by extruding the mixed material 200 ′.

[0081] In some embodiments, the water content of the mixed material 200 ′ is 4-14%.

[0082] Preferably, the water content of the mixed material 200' is 6-12%.

[0083] S102, extruding the mixed material to form an extrusion matrix with a water content of 2-12%.

[0084] Here, the extruded matrix 200 having a water content of 2 to 12% means that the water content in the extruded matrix 200 is 2 to 12% of the total weight of the extruded matrix 200 .

[0085] The moisture content of the extruded matrix 200 is, for example, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11% or 12%, etc.

[0086] Mixed material 200' is a component of the aerosol-generating matrix. Extrusion molding is used to shape mixed material 200' into an extruded matrix 200, which has the same cross-sectional shape as the aerosol-generating matrix. In other words, the cross-sectional shape of extruded matrix 200 is the same as the cross-sectional shape of the aerosol-generating matrix. The extrusion process is used to shape mixed material 200' without changing the chemical properties of mixed material 200'.

[0087] It should be noted that the longitudinal direction refers to the direction in which the aerosol-generating substrate extends. For example, if the aerosol-generating substrate is formed by extrusion, the longitudinal direction is the direction in which the extruded substrate 200 extends. The cross-sectional shape refers to the shape of the extruded substrate 200 when taken along a plane perpendicular to the longitudinal direction.

[0088] 2 to 4 , extrusion molding refers to a processing method in which a mixed material 200′ is pushed forward by the screw 112 through the action between the barrel 111 and the extrusion screw 112 of the extruder 110 and formed into an extruded matrix 200 of various cross-sectional shapes through the die 1132 of the discharge port.

[0089] When the water content of the extruded matrix 200 is less than 2%, the impurities generated by the aerosol-generating matrix during the user's puffing process are high, reducing the user's puffing experience. Furthermore, if the extruded matrix 200 undergoes other subsequent processing, the extruded matrix 200 with a water content of less than 2% will be easily broken during the subsequent processing, resulting in a high defect rate in subsequent production and increased production costs. When the water content of the extruded matrix 200 is greater than 12%, the aerosol water content of the aerosol-generating matrix during the heated puffing process is high, and the aerosol temperature is difficult to reduce, which can easily cause the user to experience a "burned mouth" phenomenon during the puffing process, reducing the user's puffing experience. Therefore, without requiring high-temperature drying, that is, without requiring additional drying equipment to dry the extruded matrix 200, by controlling the water content of the extruded matrix 200 formed by extrusion molding within a range of 2 to 12%, the user's puffing experience can be effectively improved. Furthermore, for the extruded matrix 200 that undergoes other processing after drying, the defect rate in subsequent production can also be reduced.

[0090] The manufacturing method of the aerosol generating product provided by the embodiment of the present disclosure includes: feeding the material to form a mixed material 200' with a water content of 2 to 20%; extruding the mixed material 200' to form an extruded matrix 200 with a water content of 2 to 12%. It can be understood that the extruded matrix 200 with a water content of 2 to 12% can effectively improve the user's puffing experience. On the one hand, by controlling the water content of the mixed material 200' and the water content of the extruded matrix 200 formed by extrusion, it is possible to choose not to dry the extruded matrix 200 through additional drying equipment, so that the extruded matrix 200 can be shaped and have a certain hardness for subsequent steps, shortening the process of preparing the aerosol generating product, solving the problems of long drying time and high energy consumption, thereby improving production efficiency and reducing production costs. On the other hand, the extruded matrix 200 does not need to be dried at high temperature, which improves the loss of effective substances in the extruded matrix 200 during the drying process, improves the quality of the extruded matrix 200, and improves the uniformity and stability of the extruded matrix 200.

[0091] In some embodiments, the manufacturing method further includes step S703.

[0092] Step S703: the extruded matrix is ​​shaped by natural cooling.

[0093] Here, during the natural cooling and shaping process of the extruded matrix 200, while the hardness of the extruded matrix 200 is increased, at least part of the components (such as the adhesive) in the extruded matrix 200 is converted from a viscous fluid state to a solid state, and the surface is solidified into a film, which also has the effect of physically isolating the extruded matrix 200 from absorbing water, which is beneficial to moisture-proofing.

[0094] If the extruded matrix 200 is to undergo other subsequent processing, the extruded matrix 200 can be shaped by natural cooling so that the hardness of the extruded matrix 200 after natural cooling and shaping can meet the requirements of other subsequent processing (such as slitting).

[0095] In the above-described embodiment, the extruded matrix 200 is shaped by natural cooling. On the one hand, the extruded matrix 200 does not need to be dried using additional drying equipment to achieve the desired shape. This shortens the manufacturing process for the aerosol-generating product, solves the problems of long drying times and high energy consumption, and thus improves production efficiency and reduces production costs. Furthermore, the elimination of the need for high-temperature drying mitigates the loss of active ingredients during the drying process, improves the quality of the extruded matrix 200, and enhances the uniformity and stability of the extruded matrix 200.

[0096] Another embodiment of the present disclosure provides an aerosol-generating substrate manufacturing apparatus 100, as shown in Figures 2 to 4. The aerosol-generating substrate manufacturing apparatus 100 primarily includes an extruder 110. The extruder 110 is configured to extrude a mixed material 200' to form an extruded matrix 200; at least a portion of the mixed material 200' is fed in solid form.

[0097] The extruder 110 is used to extrude the mixed material 200' to form the mixed material 200' into an extruded matrix 200. At least a portion of the mixed material 200' is fed in a solid form.

[0098] The extruder 110 can be a single-screw 112 extruder 110 or a twin-screw 112 extruder 110. A twin-screw 112 extruder 110 is preferably used because, compared with a single-screw 112 extruder 110, the twin-screw 112 extruder 110 can mix and homogenize the mixed material 200′ during the conveying process of the mixed material 200′, thereby improving product stability, and the extrusion efficiency of the twin-screw 112 extruder 110 is higher than that of the single-screw 112 extruder 110.

[0099] For example, referring to Figures 2 to 4, the extruder 110 includes a barrel 111 and a feeding port 114 connected to the barrel 111. The number of the feeding ports 114 can be one or more. For example, the extruder 110 shown in Figures 2 to 4 has two feeding ports 114. In other embodiments, the number of the feeding ports 114 can be greater than two.

[0100] When there are multiple feeding ports 114, for solid mixed materials 200', mixed materials 200' can be added from different feeding ports 114 to increase the feeding speed. Especially for paste-like mixed materials 200' with high viscosity, adding paste-like mixed materials 200' from different feeding ports 114 can significantly increase the feeding speed.

[0101] Regarding the method of feeding the mixed material 200′ separately as solid raw materials and liquid raw materials, the solid raw materials and liquid raw materials can be added to the barrel 111 of the extruder 110 from the same feeding port 114 respectively. When there are multiple feeding ports 114, at least one feeding port 114 can be a solid raw material feeding port 114, and at least one feeding port 114 can be a liquid raw material feeding port 114. The solid raw material is added to the barrel 111 of the extruder 110 from the solid raw material feeding port 114, and the liquid raw material is added to the barrel 111 of the extruder 110 from the liquid raw material feeding port 114.

[0102] When a plurality of solid raw material feeding ports 114 are provided, each solid raw material feeding port 114 can be used to add the same solid raw material or different solid raw materials.

[0103] Likewise, when a plurality of liquid raw material feeding ports 114 are provided, each liquid raw material feeding port 114 may be used to add the same liquid raw material or may be used to add different liquid raw materials.

[0104] 3 and 4 , a screw 112 may be provided at the feed port 114 as needed to further homogenize the mixed material 200 ′.

[0105] In addition, the feeding port 114 may also be configured as a detachable structure so as to facilitate assembly of the feeding port 114 according to the required quantity.

[0106] Referring to Figures 3 and 4, the extruder 110 may also be provided with a vacuum interface 115 connected to the barrel 111. Before feeding, the barrel 111 of the extruder 110 may be vacuumed to form a negative pressure in the barrel 111. This can defoam the mixed material 200' in the barrel 111, and is conducive to the full mixing of the raw materials in the mixed material 200'.

[0107] It should be noted that the extrusion temperature (ie, the temperature inside the cavity of the extruder 110 ) of the embodiment of the present disclosure is not limited herein. For example, the extrusion temperature of the extrusion molding is 90° C. to 300° C. (inclusive).

[0108] For example, the extrusion temperature of extrusion molding is 90℃, 100℃, 200℃, 210℃, 220℃, 230℃, 240℃, 250℃, 255℃, 260℃, 265℃, 270℃, 275℃, 280℃, 284℃, 288℃, 290℃, 296℃ or 300℃, etc.

[0109] It is understood that when the water content of the mixed material 200' is between 14% and 20%, the mixed material 200' has relatively good fluidity in the extruder 110 and can be extruded at room temperature. However, a higher extrusion temperature is required to allow excess water in the mixed material 200' to dissipate at the discharge port, so that the water content of the extruded matrix 200 obtained by extrusion molding is 2% to 12%, thereby improving the user's smoking experience. When the water content of the mixed material 200' is between 2% and 14%, the mixed material 200' has poor fluidity in the extruder 110, and a higher temperature is required to convert the solid state to a molten state. Therefore, the extrusion temperature of the extrusion molding needs to be controlled within an appropriate range to improve the fluidity of the mixed material 200' in the extruder 110 and heat the solid material to a molten state.

[0110] When the extrusion temperature is between 90°C and 300°C, the mixed material 200′ exhibits good fluidity, which facilitates the molding of the mixed material 200′. This ensures stable rheological properties of the mixed material 200′, an appropriate flow rate of the mixed material 200′, and an appropriate pressure at the outlet of the mixed material 200′, which facilitates the molding of the mixed material 200′. This results in high production speed and efficiency, and the endogenous components of the extruded matrix 200 are stable. Furthermore, at this temperature, the torque provided by the extruder 110 is low, resulting in low energy consumption for the extruder 110. This not only extends the service life of the extruder 110 but also reduces production costs.

[0111] More preferably, the extrusion temperature of the extrusion molding is 100°C to 200°C.

[0112] Furthermore, the extrusion temperature of the extrusion molding is 100°C to 135°C.

[0113] In some embodiments, the extrusion pressure of the extrusion molding is 0.5 bar to 300 bar (inclusive).

[0114] The extrusion pressure described in the embodiment of the present disclosure refers to the extrusion pressure of the extrusion die 113 located at the outlet of the extruder 110 , for example, the extrusion pressure of the die head located at the outlet of the extruder 110 .

[0115] The extrusion pressure affects the molding shape, surface smoothness, yield rate, and production rate of the aerosol-generating matrix. During the extrusion process, when the extrusion pressure is lower than 0.5 bar, the molding rate of the aerosol-generating matrix is ​​low, and the product defect rate increases, which in turn leads to a slow production rate and increased production costs. When the extrusion pressure is higher than 300 bar, the transmission structure of the extruder 110 is loaded with a high load (the torque required to be provided is high), which leads to a reduction in the service life of the extruder 110. Therefore, controlling the extrusion pressure within the range of 0.5 bar to 300 bar can not only improve the molding rate of the aerosol-generating matrix, but also extend the service life of the extruder 110.

[0116] More preferably, the extrusion pressure of low-temperature extrusion is 5 bar-200 bar (including 5 bar and 200 bar).

[0117] For example, in one embodiment, referring to FIG6 , the aerosol-generating substrate is formed with an air channel 200a, which extends through at least one longitudinal end of the aerosol-generating substrate. For example, the air channel 200a extends through one longitudinal end of the aerosol-generating substrate. In another example, the air channel 200a extends through both longitudinal ends of the aerosol-generating substrate. Airflow can flow longitudinally from one end of the aerosol-generating substrate to the other end of the aerosol-generating substrate. In this way, the airflow formed by the aerosol carried by the air can flow more smoothly, with less airflow resistance, which can significantly reduce the suction resistance during the inhalation process and enhance the inhalation experience.

[0118] In one embodiment, referring to FIG. 9 to FIG. 11 , the air channel 200 a may be formed inside the aerosol-generating substrate or on the outer peripheral surface of the aerosol-generating substrate.

[0119] In one embodiment, as shown in FIG9 , the air passage 200a is a linear air passage 200a extending in a straight line. The linear air passage 200a is easy to form, which reduces manufacturing difficulty. The flow resistance of the airflow in the linear air passage 200a is relatively small.

[0120] In one embodiment, referring to FIG. 10 , airway 200a is a curved airway 200a, wherein at least a portion of the aperture of curved airway 200a is curved with a curvature of 0.001°. Curved airway 200a can significantly increase the airflow path without significantly increasing the length of the aerosol-generating substrate, thereby extending the contact time between the airflow and the aperture wall of curved airway 200a and improving the aerosol extraction rate.

[0121] In one embodiment, referring to FIG11 , the curved airway 200a is in the shape of a spiral line. That is, the three-dimensional shape of the curved airway 200a is in the shape of a spatial spiral line. For example, the curved airway 200a of the extruded matrix 200 may be formed by rotating the extrusion die 113 during the extrusion process. The line connecting any point of the spiral curved airway 200a and the starting point has an inclination angle relative to its axis. The spiral curved airway 200a can greatly extend the flow path of the airflow, precipitate the aerosol from the aerosol generating matrix into the curved airway 200a, increase the flow velocity of the aerosol in the aerosol generating matrix, thereby increasing the impact force of the airflow, allowing the aerosol to be evenly mixed, improving the uniformity of the aerosol, and enhancing the user's inhalation experience.

[0122] It should be understood that the extruded substrate 200 is a semi-finished product of the aerosol-generating substrate. The extruded substrate 200 has the same morphology as the aerosol-generating substrate. In the case where the aerosol-generating substrate has air channels 200a, the extruded substrate 200 also has the same air channels 200a.

[0123] There is no limitation on the cross-sectional shape of the airway 200a located inside the aerosol generating matrix. For example, the cross-sectional shape can be circular, polygonal (including but not limited to triangle, square, prism, etc.), elliptical, runway-shaped or irregular, etc., where irregular refers to other symmetrical or asymmetrical shapes other than the shapes listed above.

[0124] The cross-sectional shape of the air channel 200a located on the outer peripheral surface of the aerosol generating substrate can be semicircular, semi-elliptical, polygonal or irregular, wherein irregular refers to other symmetrical or asymmetrical shapes other than the shapes listed above.

[0125] The number of air passages 200a is not limited, and there can be one or more air passages 200a. "More" means two or more.

[0126] It should be noted that micropores exist within the aerosol-generating matrix. For example, in the aerosol-generating matrix of a particle assembly, the gaps between particles constitute micropores. However, the airway 200a described in the present disclosure is different from micropores. The airway 200a described in the present disclosure is a pore in the macroscopic sense, while the micropores are pores in the microscopic sense. The cross-sectional area and length of the airway 200a are much larger than those of the micropores. The airway 200a is primarily formed by, for example, the extrusion die 113. Therefore, the cross-sectional area and length of the airway 200a can be changed according to design requirements. The size of the micropores is determined by the gaps between particles. For example, the mixed material 200′ is a granular material, and the extrudate formed by extruding the mixed material 200′ has micropores. The cross-sectional area and length of the micropores are difficult to significantly change through processing.

[0127] In one embodiment, the mixed material 200' is subjected to extrusion molding, including:

[0128] The mixed material 200 ′ is extruded through the extruder 110 .

[0129] The mixed material 200' of the embodiment of the present disclosure may include plant raw materials, auxiliary raw materials, smoke-generating agent raw materials, adhesive raw materials and fragrance raw materials, wherein the plant raw materials, auxiliary raw materials and adhesive raw materials are solid raw materials, and the smoke-generating agent raw materials and fragrance raw materials are liquid raw materials.

[0130] The plant raw material is used to generate aerosols when heated. The auxiliary raw material is used to provide a skeleton support for the plant raw material. The smoke-generating agent raw material is used to generate smoke when heated. The adhesive raw material is used to bond the component raw materials. The flavor raw material is used to provide a characteristic aroma. In this way, the plant raw material and the smoke-generating agent raw material can ensure the amount of aerosol generated, while the flavor raw material can enhance the release of aroma during the inhalation process and improve the user experience. The auxiliary raw material can not only improve the fluidity of the mixed material 200', but also make the aerosol-generating matrix have a porous structure to facilitate the extraction and flow of the aerosol. The adhesive raw material ensures that the plant raw material and the auxiliary raw material constitute a stable mixture to avoid a loose structure.

[0131] For example, the plant raw material can be one or more combinations of crushed tobacco leaves, tobacco leaf fragments, tobacco stems, tobacco dust, and flavorful plants, forming a powder. Plant raw materials are the core source of flavor, and endogenous substances in plant raw materials can produce physiological satisfaction in users. Endogenous substances, such as alkaloids, enter the human bloodstream and stimulate the pituitary gland to produce dopamine, thereby achieving physiological satisfaction.

[0132] For example, the auxiliary agent raw material can be one or more combinations of inorganic fillers, lubricants, and emulsifiers.

[0133] Among them, the inorganic filler includes one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic filler can provide a skeletal support for the plant material and also has micropores, which can increase the porosity of the aerosol-generating matrix, thereby increasing the aerosol release rate. The lubricant includes one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. The lubricant can increase the fluidity of the plant material powder, reduce the friction between the plant material powders, make the overall density of the plant material powder distribution more uniform, and also reduce the pressure required for the extrusion molding process, reducing the wear of the extrusion die 113. The emulsifier includes one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. The emulsifier can, to a certain extent, slow down the loss of flavor substances during storage, increase the stability of flavor substances, and improve the sensory quality of the product.

[0134] Exemplarily, the smoke-generating agent raw materials may include: monohydric alcohols (such as menthol); polyhydric alcohols (such as propylene glycol, glycerol, triethylene glycol, 1,3-butanediol and tetraethylene glycol); esters of polyhydric alcohols (such as triacetin, triethyl citrate, diacetin mixture, triethyl citrate, benzyl benzoate, tributyrin); monocarboxylic acid; dicarboxylic acid; polycarboxylic acid (such as lauric acid, myristic acid) or aliphatic esters of polycarboxylic acids (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, Triactin, meso-erythritol, diacetin mixture, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, tributyrin, lauryl acetate) in one or more combinations.

[0135] Illustratively, the binder material is brought into close contact with the component materials by wetting the interface, generating intermolecular attraction, thereby serving to bind the component materials, such as powders and liquids. The binder material can be a natural plant extract, a non-ionically modified viscous polysaccharide, including one or more combinations of tamarind polysaccharides, guar gum, and modified cellulose (e.g., carboxymethyl cellulose). The binder is used to bond the particles together, preventing them from loosening, and further improves the water resistance of the aerosol-generating matrix, while being harmless to the human body.

[0136] For example, flavor raw materials are solid or liquid substances used to provide characteristic aromas, such as hay, roasted sweet, or nicotine. Flavor raw materials can include one or more combinations of tobacco or other plants, aromatic plant extracts, extracts, essential oils, and absolutes. Flavor raw materials can also include monomeric flavor substances, such as one or more combinations of megastigmatrienone, neophytadiene, geraniol, and nerol.

[0137] For example, in 100 parts by weight of the mixture 200', the plant raw materials are 30 to 90 parts, the auxiliary raw materials are 1 to 15 parts, the smoke agent raw materials are 5 to 30 parts, the adhesive raw materials are 1 to 10 parts, and the flavor raw materials are 1 to 15 parts.

[0138] In one embodiment, the mixed material 200' is in at least one of granular, powdery and paste form.

[0139] Illustratively, the particle size of the granules may be 75 μm to 3000 μm (inclusive), and the particle size of the powder may be smaller than that of the granules.

[0140] In addition, when the liquid content is high, the solid raw material and the liquid raw material can be combined to form a paste. The paste-like mixed material 200' is closer to the form of a solid (that is, the mixed material 200' will not flow). Therefore, the paste can also be considered as the solid described in the embodiment of the present disclosure.

[0141] The granular and powdered mixture 200′ can improve the smoothness, continuity, and stability of feeding, improve the stability of extrusion pressure, and thus improve the stability of the extruded matrix 200, thereby improving production efficiency and yield rate. Compared with pressure feeding (feeding the mixture 200′ as a larger block), it can reduce stress concentration at the feeding port 114 and extend the service life of the extruder 110.

[0142] In one embodiment, the material includes a solid raw material and a liquid raw material, and feeding the material includes:

[0143] The solid raw materials and liquid raw materials are divided into two modules for feeding respectively.

[0144] That is, the solid raw material and the liquid raw material are divided into two independent modules before feeding. After the solid raw material and the liquid raw material are fed separately, they are mixed in the barrel 111 of the extruder 110.

[0145] The advantage of dividing the solid raw materials and liquid raw materials into two modules for feeding separately is that it can reduce the pre-treatment cost of the mixed material 200', ensure the continuity of the production process, and improve the consistency and uniformity of the product while improving production efficiency.

[0146] In some embodiments, the solid raw material and the liquid raw material are divided into two modules for feeding separately, which may include the following steps: adding the solid raw material; when the solid raw material moves along the material conveying direction to the addition position of the liquid raw material, adding the liquid raw material to the solid raw material.

[0147] That is to say, solid raw materials are first added to the extruder 110. After the solid raw materials enter the barrel 111 of the extruder 110, they will move along the material conveying direction toward the direction where the extrusion die 113 is located. When the solid raw materials move along the material conveying direction to the addition position of the liquid raw materials, liquid raw materials are added to the extruder 110 to mix the liquid raw materials and the solid raw materials in the barrel 111 of the extruder 110.

[0148] In addition, the feeding amount and feeding speed may be determined according to the production speed of the extruder 110 and the ratio of the raw materials in the mixed material 200 ′.

[0149] For example, please refer to Figures 2 to 4. For the multiple feeding ports 114 set on the extruder 110, it is equivalent to the liquid raw material feeding port 114 being located downstream of the solid raw material feeding port 114 along the material conveying direction. For example, the feeding port 114 corresponding to the mixed material 200' shown in Figures 2 to 4 is the solid raw material feeding port 114, and the other feeding port 114 located downstream of the feeding port 114 along the material conveying direction is the liquid raw material feeding port 114.

[0150] Since the extruder 110 mainly relies on the rotation of the screw 112 to convey the mixed material 200', and the screw 112 and the inner wall of the barrel 111 of the extruder 110 are not completely sealed, that is, there is a gap between the screw 112 and the inner wall of the barrel 111 of the extruder 110. If the liquid raw material is added first, the liquid raw material is likely to leak from the gap. Therefore, the solid raw material is added first, and the liquid raw material is added when the solid raw material moves along the material conveying direction to the addition position of the liquid raw material. This can better avoid the leakage of the liquid raw material.

[0151] In some embodiments, the material includes a solid raw material and a liquid raw material, and feeding the material may include the following steps: premixing the solid raw material; adding the liquid raw material to the premixed solid raw material to form a powder slurry; and feeding the powder slurry.

[0152] That is to say, the solid raw materials and liquid raw materials are divided into two independent modules before feeding. After the solid raw materials and liquid raw materials are pre-mixed, the solid raw materials are pre-mixed first, and then the liquid raw materials are added to the pre-mixed solid raw materials to form a powder slurry after mixing, and then the powder slurry is fed.

[0153] Since the extruder 110 mainly relies on the rotation of the screw 112 to convey the mixed material 200', and the screw 112 and the inner wall of the barrel 111 of the extruder 110 are not completely sealed, that is, there is a gap between the screw 112 and the inner wall of the barrel 111 of the extruder 110. If the liquid raw material is directly added to the extruder 110, the liquid raw material will easily leak from the gap. Therefore, the liquid raw material is added to the pre-mixed solid raw material to form a powder slurry, and then the powder slurry is fed, which can better avoid the leakage of the liquid raw material.

[0154] In some embodiments, feeding the material may include the following steps: mixing the material to form a slurry; and feeding the slurry.

[0155] That is, the plant raw materials, auxiliary raw materials, smoke generating agent raw materials, adhesive raw materials and fragrance raw materials are pre-mixed to form a slurry, and then the slurry is added to the extruder 110 for extrusion molding.

[0156] The advantage of first mixing the materials to form a slurry and then feeding the slurry is that the mixed material 200' has better consistency, ensuring the continuity of the production process, and improving the consistency and uniformity of the product while improving production efficiency.

[0157] In some embodiments, feeding the material may include the following steps: mixing the material to form a slurry; forming a granular slurry from the slurry by a granulation method; and feeding the granular slurry.

[0158] That is, the plant raw materials, auxiliary raw materials, smoke agent raw materials, adhesive raw materials and flavor raw materials are pre-mixed to form a slurry, and then the slurry is formed into granular slurry of uniform size through a granulation method, and then the granular slurry is added to the extruder 110 for extrusion molding.

[0159] The advantage of first mixing the materials to form a slurry, then forming the slurry into a granular slurry through a granulation method, and then feeding the granular slurry is that it can improve the smoothness, continuity and stability of the feeding of the mixed material 200', improve the stability of the basic pressure, and then improve the stability of the shape of the extruded matrix 200, improve production efficiency and yield rate, and compared with a pressure feeder, it can reduce stress concentration at the feeding port and extend the service life of the extruder 110.

[0160] There are many ways to granulate. For example, granules can be formed by extrusion spheronization. Extrusion spheronization is to mix the solid raw materials and liquid raw materials of the mixed material 200' into a slurry, then extrude the slurry into strips, cut the strips into rod-shaped pellets, and finally roll the rod-shaped pellets into granules.

[0161] In addition to extrusion spheronization, granulation can also be achieved by fluidized bed granulation, stirring granulation, and dry extrusion granulation. When these granulation methods are used, the mixed material 200' does not need to be mixed to form a slurry first. The solid and liquid raw materials are mixed simultaneously during granulation, thereby shortening the manufacturing process and improving production efficiency.

[0162] More preferably, the particle size of the granules may be 75 μm to 3000 μm.

[0163] It should be noted that the granulation described above is only for illustrating the method of manufacturing the granular mixture 200′, and does not mean that the manufacturing method of the aerosol generating matrix disclosed in the present invention must include a granulation step when the granular mixture 200′ is selected. In other words, granulation can be carried out separately from the manufacturing method disclosed in the present invention, and the granular mixture 200′ can be directly added during feeding.

[0164] In one embodiment, referring to FIG. 4 , the extrusion direction of the extrusion molding is horizontal.

[0165] Horizontal extrusion means that the extrusion die 113 at the outlet of the extruder 110 is horizontally arranged, and the extruded matrix 200 is extruded in a horizontal direction, or in other words, the extrusion direction of the extruded matrix 200 is parallel to the horizontal plane.

[0166] For the extruded matrix 200 forming the spiral air channel 200a, after being extruded from the extruder 110, the extruded matrix 200 can be directly fed into the conveying device through rotation. Horizontal extrusion can reduce the direct release of stress generated by the rotation of the extruded matrix 200 (the generated stress can be eliminated by heating), thereby improving the yield rate of the aerosol-generating matrix having the spiral air channel 200a.

[0167] In one embodiment, referring to FIG. 2 and FIG. 3 , the extrusion direction of the extrusion molding is a vertical direction.

[0168] The vertical direction means that the extrusion die 113 at the outlet of the extruder 110 is arranged downward, and the extruded matrix 200 is extruded along the direction of gravity, or in other words, the extrusion direction of the extruded matrix 200 is perpendicular to the horizontal plane.

[0169] For the extruded substrate 200 forming the straight air channel 200 a , vertical extrusion can improve the yield rate, reduce the investment cost of the extruder 110 , and also reduce the floor space occupied by the extruder 110 .

[0170] In one embodiment, the extrusion direction of the extrusion molding is an inclined direction.

[0171] Inclined extrusion means that the extrusion die 113 at the outlet of the extruder 110 is arranged inclined, and the angle between the extrusion direction of the extruded matrix 200 and the horizontal plane is greater than 0° and less than 90°.

[0172] Inclined extrusion can not only reduce the extrusion pressure of the mixed material 200 ′, but also facilitate the space design of other equipment.

[0173] In one embodiment, referring to Figures 5 and 6, the extrusion die 113 can be a single-mold single extrusion die 113, that is, there is only one bottom die 1131 at the outlet of the extruder 110, and the discharge end of the bottom die 1131 has a mouth die 1132. After the mixed material 200' passes through the mouth die 1132, an extruded matrix 200 with an air channel 200a can be formed.

[0174] In one embodiment, referring to FIG7 , the extrusion die 113 may also be a single-die, multi-port die. Specifically, the extruder 110 has a single bottom die 1131 at its outlet, and the discharge end of the bottom die 1131 has multiple port dies 1132. After the mixed material 200′ passes through the multiple port dies 1132, multiple extruded matrices 200 are simultaneously formed. When the screw 112 of the extruder 110 is relatively large, a single-die, multi-port die may be used. This improves production efficiency and is more suitable for mass production.

[0175] In one embodiment, referring to FIG8 , the extrusion die 113 can also be a multi-mode, multi-port die. Specifically, the adapter 116 at the outlet of the extruder 110 is connected to multiple base dies 1131. Each base die 1131 has multiple port dies 1132 at its outlet. After the mixed material 200′ passes through the port dies 1132 on each base die 1131, multiple extruded matrices 200 are simultaneously formed. When the screw 112 of the extruder 110 is relatively large, a multi-mode, multi-port die can also be used. This can improve production efficiency and is more suitable for mass production.

[0176] In one embodiment, the manufacturing method includes:

[0177] The extruded matrix 200 is cut into media segments of predetermined lengths.

[0178] 2 to 4 , the extruded matrix 200 can be cut to a predetermined length by the cutting tool 121 of the cutting device 120. Thus, the extruded matrix 200 of the predetermined length can be applied to the subsequent packaging device 130, reducing the requirements for subsequent devices.

[0179] It is understandable that the specific value of the preset length is not limited, and the preset length can be set according to the aerosol generating matrix or according to the situation of the manufacturing device 100.

[0180] In some embodiments, the extruded matrix 200 is a continuous structure. That is, during the extrusion process, the extruded matrix 200 is continuously extruded, resulting in a continuous structure. Continuous extrusion can improve extrusion efficiency, and the extruded matrix 200 can be subsequently cut into predetermined lengths to shorten the length.

[0181] In some embodiments, the extruded matrix 200 has a segmented structure with a predetermined length. That is, during the extrusion process, the extruded matrix 200 naturally separates upon reaching the predetermined length. For example, the extruded matrix 200 may separate from the extrusion die 113 upon reaching a predetermined length due to reaching a critical value. In this way, the predetermined length of the extruded matrix 200 can be the length of the aerosol-generating matrix, and the extruded matrix 200 may not need to be segmented, thereby eliminating the need for a segmenting device 120 and reducing equipment costs.

[0182] The slitting tool 121 slits the extruded matrix 200 by physical contact or non-physical contact.

[0183] Physical contact refers to slitting the extruded matrix 200 by direct contact of the slitting tool 121 with the extruded matrix 200. For example, the slitting tool 121 can be a rotating rotary cutter, a cutting blade, a cutting wire, a roller cut, or an extruder.

[0184] Non-physical contact means that the slitting tool 121 does not need to directly contact the extruded matrix 200 to slit the extruded matrix 200. For example, the slitting tool 121 releases laser, plasma, air knife or water knife to cut the extruded matrix 200.

[0185] The manufacturing apparatus 100 employed in the embodiments of the present disclosure can be used in the manufacturing method of the embodiments of the present disclosure. The description of the embodiment of the manufacturing apparatus 100 is similar to the description of any of the embodiments of the manufacturing method, and has the same beneficial effects as the embodiments of the manufacturing method. For technical details not disclosed in the manufacturing method of the embodiments of the present disclosure, please refer to the description of the embodiments of the extruder 110 and the slitting device 120 of the embodiments of the present disclosure for understanding.

[0186] For example, in one embodiment, the manufacturing method includes: correcting the shape of the extruded matrix 200. Correcting the shape refers to correcting the circumference and / or straightness of the extruded matrix 200 using a jig. Straightness refers to the degree of curvature of the extruded matrix 200 in the longitudinal direction.

[0187] Since the texture of the extruded matrix 200 is usually relatively soft, during the manufacturing process of the extruded matrix 200, the circumference of the extruded matrix 200 may be deformed and / or the extruded matrix 200 may be bent in the longitudinal direction. For example, during the process of slitting the extruded matrix 200 by the slitting device 120, the circumference of the extruded matrix 200 may be deformed and / or the extruded matrix 200 may be bent in the longitudinal direction. Therefore, the extruded matrix 200 can be calibrated for circumference and / or straightness using a jig.

[0188] It should be noted that the shaping of the extruded matrix 200 can be performed at any time after step S102 when shaping is required. The shaping of the extruded matrix 200 can be performed once or multiple times throughout the entire manufacturing process of the aerosol generating matrix. For example, the shaping of the extruded matrix 200 can be performed before and / or after slitting.

[0189] In one embodiment, the manufacturing method includes:

[0190] A wrapping layer is wrapped around the outer surface of the aerosol generating substrate.

[0191] A wrapping layer is wrapped around the outer surface of the aerosol-generating substrate by the packaging device 130, and the aerosol-generating substrate can be protected by the wrapping layer.

[0192] The wrapping layer includes but is not limited to one or more combinations of materials such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE (Polyethylene), PBAT (Polybutylene Adipate Terephthalate), etc.

[0193] In some embodiments, the outer surface of the aerosol-generating substrate may be wrapped with a wrapping layer and then combined with the functional segment to form an aerosol-generating article.

[0194] In other embodiments, the aerosol-generating substrate may be first combined with the functional segment, and then the outer surfaces of the aerosol-generating substrate and the functional segment are wrapped with a wrapping layer to form an aerosol-generating product.

[0195] In some other embodiments, a wrapping layer may be first wrapped around the outer surface of the aerosol-generating substrate, and then combined with the functional segment and wrapped with the wrapping layer to form an aerosol-generating article. In other words, the outer surface of the aerosol-generating substrate may be wrapped with multiple wrapping layers.

[0196] In the description of the present disclosure, the descriptions with reference to the terms "in one embodiment", "in some embodiments", "in other embodiments", "in yet other embodiments", or "exemplary" etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present disclosure.
