[0003] This application relates to the field of aerosol-generating substrate technology, and in particular to a method for manufacturing an aerosol-generating product and a manufacturing apparatus. Background Technology

[0004] An aerosol-generating substrate can form an aerosol through an ignition method or through a heated non-combustion method. In the case of a heated non-combustion aerosol-generating substrate, the aerosol-generating substrate is heated using an external heat source only enough to release an aerosol, ensuring that the aerosol-generating substrate does not combust, and a smoke-generating agent is loaded so that, upon use, the aerosol-generating substrate is heated to release the smoke-generating agent and form an aerosol.

[0005] The core of current manufacturing systems primarily consists of three methods: casting, coating, and roll pressing. These methods require controlling the moisture and shape of the substrate through drying. However, the related methods and systems suffer from issues such as lengthy processes, high flow of intermediate products from raw materials to finished goods, low production efficiency, high production costs, and a susceptibility to loss of active materials during the manufacturing process.

[0049] It should be noted that, unless conflicts arise, the embodiments and technical features of the embodiments in this application may be combined with one another, and the detailed description of specific embodiments is understood as an explanatory description of this application and should not be construed as a limitation to this application.

[0050] In this application, the temperature unit “°C” is degrees Celsius. The pressure unit “bar” is bar. The unit “μm” is a micrometer. The viscosity unit “pa·s” is Pascal·second. The unit “pa” is Pascal.

[0051] It needs to be explained that the aerosol-generating product includes an aerosol-generating substrate and may include a functional section, or of course, may not include a functional section.

[0052] An aerosol-generating substrate is intended to be heated to generate an aerosol. For example, an aerosol-generating substrate can be applied to generate an aerosol via a heated combustion method. An aerosol-generating substrate can also be applied to generate an aerosol via a heated non-combustion method. That is, the aerosol-generating substrate is heated to a temperature below its ignition point to generate an aerosol. The aerosol-generating substrate is not combusted during the aerosol generation process.

[0053] A functional section is installed at one end along the longitudinal direction of the aerosol-generating substrate, and the functional section includes a filtration section for filtering the aerosol. The filtration section is intended to filter the aerosol generated by the aerosol-generating substrate.

[0054] Of course, in some embodiments, the aerosol-generating product may not include a functional section.

[0055] Aerosol generating products are designed to allow a user to inhale aerosols generated by an aerosol generating substrate. For example, a user can inhale filtered aerosols by biting down on a filtration section. The aerosols generated by the aerosol generating substrate are delivered to the filtration section under the action of inhalation negative pressure.

[0056] The aerosol generating product is intended to be used with an aerosol generating device equipped with a heating component. Specifically, the heating component generates an aerosol by performing atomization on an aerosol generating substrate.

[0057] The heating method of the heating component varies, and examples include core heating, peripheral heating, and / or bottom heating. Core heating refers to inserting the heating component into the aerosol generating product to bake and heat the aerosol generating product from the inside out. Peripheral heating refers to the heating component being installed on the outside of the aerosol generating product to bake and heat the aerosol generating product from the outside in. Bottom heating refers to the heating component being located at the bottom of the aerosol generating product, whereby the heating component first heats the air, and the heated air bakes and heats the aerosol generating product from bottom to top.

[0058] What needs to be explained is that the lower part of the aerosol-generating product is a section along the longitudinal direction that is far from the functional section.

[0059] The heating method of the heating component includes, but is not limited to, resistance heating, electromagnetic heating, infrared heating, microwave heating, or laser heating.

[0060] In some embodiments, the functional section may be installed only as a filter section.

[0061] In some other embodiments, the functional section further includes a cooling section, the cooling section is located between the filtration section and the aerosol generating substrate, and the cooling section is intended to cool the aerosol before the filtration section performs filtration on the aerosol. The cooling section can improve the “mouth burn” phenomenon when a user inhales the aerosol.

[0062] The cooling material adopted in the cooling section includes, but is not limited to, one or a combination of multiple materials such as PE (polyethylene), PLA (polylactic acid), PBAT (polybutylene adipate terephthalate), PP (polypropylene), acetate fibers, and acrylic fibers.

[0063] The filtration material adopted in the filtration section includes, but is not limited to, one or a combination of multiple materials such as PE (polyethylene), PLA (polylactic acid), PBAT (polybutylene adipate terephthalate), PP (polypropylene), acetate fiber, and acrylic fiber.

[0064] The materials of the cooling section and the filtration section may be the same or different.

[0065] In the related technology, the manufacturing process of the aerosol-generating substrate has a high moisture content in the blended slurry (papermaking method > 90%, stirred slurry method > 70%, roll press method > 20%), and since there is a high-intensity drying step in all of them, it is disadvantageous for preserving fragrance components and active substances within the extruded substrate (200). Furthermore, since the aerosol-generating substrates in the related technology all have a sheet-type structure, problems such as uneven drying, large losses, and high processing costs exist during the processing process. There are problems such as a long process, a large amount of intermediate product transfer from raw materials to finished products, low production efficiency, high production costs, and a tendency for loss of active substances to occur during the manufacturing process. In addition, sheet-type aerosol substrates require secondary processing such as winding, unwinding, cutting, or embossing, and have high losses, complex process steps, and high equipment investment. In particular, the papermaking method consumes a lot of energy during the processing and causes significant environmental pollution.

[0066] To solve the above problem, embodiments of the present application provide a process for manufacturing an aerosol-generating product. FIG. 1 is a flowchart illustrating a method for manufacturing an aerosol-generating product provided in embodiments of the present application, and as illustrated in the figure, the method for manufacturing an aerosol-generating product includes the following steps S101 to S104.

[0067] In step S101, a mixture is supplied to form a mixture having a moisture content of 2 to 20%.

[0068] The moisture content of the mixed material (200´) is, for example, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, or 20%.

[0069] Here, the mixed material (200') having a moisture content of 2 to 20% indicates that the moisture content in the mixed material (200') is 2 to 20% of the total weight of the mixed material (200').

[0070] Here, the moisture in the mixed material (200') mainly consists of moisture contained in the solid module raw material, and water is not added or is supplemented in small amounts as needed.

[0071] By controlling the moisture content of the mixed material (200') to 2-20%, that is, by controlling the mixed material (200') to have a relatively low moisture content, it is advantageous to extrude the mixed material (200') to form an extruded substrate (200) with a low moisture content.

[0072] In some embodiments, the moisture content of the mixed material (200') is 4 to 14%.

[0073] Preferably, the moisture content of the mixture (200') is 6 to 12%.

[0074] In step S102, extrusion molding is performed on the mixed material so that the mixed material forms an extrusion substrate having a moisture content of 2 to 12%.

[0075] Here, the extrusion substrate (200) having a moisture content of 2 to 12% indicates that the moisture content in the extrusion substrate (200) is 2 to 12% of the total weight of the extrusion substrate (200).

[0076] The moisture content of the extruded substrate (200) is, for example, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, or 12%.

[0077] The mixed material (200') is a compositional component of the aerosol-generating substrate. Extrusion molding is performed to form the mixed material (200') to obtain an extruded substrate (200), and the extruded substrate (200) has the same cross-sectional shape as the aerosol-generating substrate. That is, the cross-sectional shape of the extruded substrate (200) and the cross-sectional shape of the aerosol-generating substrate are identical. The mixed material (200') is formed using an extrusion process, and the chemical properties of the mixed material (200') are not changed.

[0078] To be explained, the longitudinal direction refers to the extension direction of the aerosol-generating substrate. For example, if the aerosol-generating substrate adopts extrusion molding, the longitudinal direction is the extension direction of the extruded substrate (200). The cross-sectional shape refers to the shape exhibited by the extruded substrate (200) when the plane perpendicular to the longitudinal direction is taken as the cross-section.

[0079] Referring to FIGS. 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 an extruder (110), and an extrusion substrate (200) of various cross-sectional shapes is produced through the die (1132) of the discharge port.

[0080] If the moisture content in the extruded substrate (200) is less than 2%, the impurity gas generated by the aerosol generating substrate increases during the user's inhalation process, thereby degrading the user's inhalation experience. Additionally, if the extruded substrate (200) undergoes further processing, the extruded substrate (200) with a moisture content less than 2% is prone to breaking during subsequent processing, which leads to a higher defect rate and an increase in production costs. Furthermore, if the moisture content in the extruded substrate (200) is higher than 12%, the aerosol moisture content in the aerosol generating substrate increases during the heating and inhalation process, making it difficult to lower the aerosol temperature, and making it easy for the user to experience "burned mouth" during inhalation, thereby degrading the user's inhalation experience. Therefore, under the premise that there is no need to dry at a high temperature, that is, that one can choose not to perform drying treatment on the extruded substrate (200) through an additional drying device, by controlling the moisture content of the extruded substrate (200) formed by extrusion molding to within the range of 2 to 12%, the user's inhalation experience can be effectively improved, and in addition, in the case of the extruded substrate (200) that undergoes other treatment after drying, the defect rate of future production can be reduced.

[0081] The method for manufacturing an aerosol generating product provided in an embodiment of the present application comprises the steps of: supplying a material to form a mixed material (200') having a moisture content of 2 to 20%; and performing extrusion molding on the mixed material (200') so that the mixed material (200') forms an extrusion substrate (200) having a moisture content of 2 to 12%. It is understood that the extrusion substrate (200) having a moisture content of 2 to 12% can effectively improve the user's inhalation experience. On the other hand, by controlling the moisture content of the mixed material (200') and the moisture content of the extrusion molded extrusion substrate (200), it is possible to choose not to dry the extrusion substrate (200) using a separate drying device, thereby shaping the extrusion substrate (200) and ensuring it has a certain hardness for subsequent steps, thereby shortening the process manufacturing flow of the aerosol generating product, solving the problem of long drying times and high energy consumption, improving production efficiency, and lowering production costs. On the other hand, there is no need to perform high-temperature drying on the extruded substrate (200), thereby improving the situation where the extruded substrate (200) causes a loss of effective material during the drying process, improving the quality of the extruded substrate (200), and the uniformity and stability of the extruded substrate (200) are also excellent.

[0082] In some embodiments, the manufacturing method further includes step S103.

[0083] In step S103, the extruded substrate is shaped through natural cooling.

[0084] Here, during the process in which the extruded substrate (200) is shaped by natural cooling, the hardness of the extruded substrate (200) is improved, and at the same time, at least some components (e.g., adhesive) in the extruded substrate (200) are converted from a visceral state to a solid state, and the surface hardens to form a film, which also has the effect of physically blocking the absorption of the extruded substrate (200), making it advantageous for moisture resistance.

[0085] If the extruded substrate (200) undergoes further processing, the extruded substrate (200) is shaped through natural cooling, so that the hardness of the extruded substrate (200) after natural cooling and shaping can meet the requirements of further processing (e.g., cutting).

[0086] In the above embodiment, since the extruded substrate (200) is shaped through natural cooling, on the one hand, the extruded substrate (200) can be shaped without the need to perform drying treatment on the extruded substrate (200) using a separate drying device, thereby shortening the process manufacturing flow of the aerosol generating product and solving the problem of long drying time and high energy consumption, thereby improving production efficiency and reducing production costs. On the other hand, since there is no need to perform drying at high temperatures, the situation in which the extruded substrate (200) causes loss of effective material during the drying process is improved, thereby improving the quality of the extruded substrate (200), and the uniformity and stability of the extruded substrate (200) are also excellent.

[0087] Another embodiment of the present application further provides a manufacturing apparatus (100) for an aerosol-generating substrate, with reference to FIGS. 2 through 4, wherein the manufacturing apparatus (100) mainly comprises an extruder (110). The extruder (110) is for performing extrusion molding on a mixture (200') so that the mixture (200') forms an extrusion substrate (200), and at least a portion of the mixture (200') is supplied in the form of a solid.

[0088] The extruder (110) is intended to perform extrusion molding on the mixed material (200') so that the mixed material (200') forms an extrusion substrate (200). Here, at least a portion of the mixed material (200') is supplied in the form of a solid.

[0089] The extruder (110) may be a single screw (112) extruder (110) or a double screw (112) extruder (110), and preferably a double screw (112) extruder (110) is adopted, because compared to a single screw (112) extruder (110), the double screw (112) extruder (110) can perform mixing and homogenization on the mixed material (200') during the transport process of the mixed material (200'), thereby improving product stability, and the extrusion efficiency of the double screw (112) extruder (110) is higher than that of the single screw (112) extruder (110).

[0090] For example, referring to FIGS. 2 to 4, the extruder (110) includes a barrel (111) and a feed port (114) connected to and passing through the barrel (111). The number of feed ports (114) may be one or multiple. For example, the extruder (110) illustrated in FIGS. 2 to 4 has two feed ports (114), and in some other embodiments, the number of feed ports (114) may be greater than two.

[0091] When there are multiple supply ports (114), the supply speed can be improved by adding the mixed material (200') from different supply ports (114) for the solid mixed material (200'), and especially in the case of the paste-like mixed material (200') with high viscosity, the supply speed can be significantly improved by adding the paste-like mixed material (200') from different supply ports (114).

[0092] Regarding the method of dividing the mixed material (200') into solid raw material and liquid raw material and supplying them separately, the solid raw material and the liquid raw material can each be added into the barrel (111) of the extruder (110) from the same supply port (114), and if there are multiple supply ports (114), at least one supply port (114) may be a solid raw material supply port (114) and at least one supply port (114) may be a liquid raw material supply port (114), and the solid raw material is added into the barrel (111) of the extruder (110) from the solid raw material supply port (114), and the liquid raw material is added into the barrel (111) of the extruder (110) from the liquid raw material supply port (114).

[0093] When multiple solid raw material supply ports (114) are installed, each solid raw material supply port (114) can add the same solid raw material and each can add different solid raw materials.

[0094] Likewise, if multiple liquid raw material supply ports (114) are installed, each liquid raw material supply port (114) can add the same liquid raw material and each can add different liquid raw materials.

[0095] Referring to FIGS. 3 and 4, if necessary, an additional screw (112) may be installed in the supply port (114) to further homogenize the mixed material (200').

[0096] Additionally, the supply port (114) may be installed in a detachable structure so that the supply port (114) can be installed according to the required number.

[0097] Referring to FIGS. 3 and 4, the extruder (110) may further be equipped with a vacuum suction interface (115) connected to and passing through a barrel (111), and by performing a vacuum suction treatment on the inside of the barrel (111) of the extruder (110) before supply to form negative pressure inside the barrel (111), a degassing treatment can be performed on the mixed material (200') inside the barrel (111), which is advantageous for sufficient mixing of each raw material among the mixed material (200').

[0098] It should be noted that the extrusion temperature of the embodiments of the present application (i.e., the temperature inside the cavity of the extruder (110)) is not limited thereto. For example, the extrusion temperature of the extrusion molding is 90°C to 300°C (including 90°C and 300°C).

[0099] For example, the extrusion temperature of the extrusion molding is 90℃, 100℃, 200℃, 210℃, 220℃, 230℃, 240℃, 250℃, 255℃, 260℃, 265℃, 270℃, 275℃, 280℃, 284℃, 288℃, 290℃, 296℃, or 300℃, etc.

[0100] It is understandable that when the moisture content of the mixed material (200') is 14-20%, the mixed material (200') has relatively good fluidity within the extruder (110), so that extrusion molding is possible at room temperature, but a relatively high extrusion temperature is required so that the excessive moisture in the mixed material (200') is dispersed at the outlet in order to make the moisture content of the extruded substrate (200) obtained by extrusion molding 2-12%, thereby improving the user's inhalation experience. When the moisture content of the mixed material (200') is 2-14%, the mixed material (200') has poor fluidity within the extruder (110), and a high temperature is required to convert from a solid state to a molten state, so the extrusion temperature of the extrusion molding is controlled within one suitable range to improve the fluidity of the mixed material (200') within the extruder (110) and to heat the raw material in a solid state to a molten state.

[0101] When the extrusion temperature is 90°C to 300°C, the fluidity of the mixed material (200') is good, which is advantageous for molding the mixed material (200'), the rheological properties of the mixed material (200') are stable, the flow rate of the mixed material (200') is appropriate, and the pressure at the outlet of the mixed material (200') is appropriate, which is advantageous for molding the mixed material (200'), the production speed is fast, the production efficiency is high, and the end-toughness component of the extruded extruded substrate (200) is stable. In addition, at the above temperature, the torque provided by the extruder (110) is relatively low, so the energy consumption of the extruder (110) is relatively low, and the service life of the extruder (110) is improved, and production costs can be lowered.

[0102] More preferably, the extrusion temperature of the extrusion molding is 100℃ to 200℃.

[0103] Furthermore, the extrusion temperature of the extrusion molding is 100℃ to 135℃.

[0104] In some embodiments, the extrusion pressure of the extrusion molding is 0.5 bar to 300 bar (including 0.5 bar and 300 bar).

[0105] The extrusion pressure of the embodiment of the present application refers to the extrusion pressure of the extrusion mold (113) located at the outlet of the extruder (110), for example, the extrusion pressure of the mold head located at the outlet of the extruder (110).

[0106] Extrusion pressure affects the molding shape, surface smoothness, yield rate, and production speed of the aerosol-generating substrate. In the extrusion process, if the extrusion pressure is less than 0.5 bar, the molding rate of the aerosol-generating substrate is low, and the product defect rate increases, which leads to a slower production speed and increased production costs. If the extrusion pressure is higher than 300 bar, the load on the extruder's (110) power structure increases (the torque required to be provided increases), which leads to a reduced service life of the extruder (110). Therefore, by controlling the extrusion pressure within the range of 0.5 bar to 300 bar, not only can the molding rate of the aerosol-generating substrate be improved, but the service life of the extruder (110) can also be extended.

[0107] More preferably, the extrusion pressure of the low-temperature extrusion is 5 bar to 200 bar (including 5 bar and 200 bar).

[0108] For example, in one embodiment, referring to FIG. 6, an airflow passage (200a) is formed in the aerosol generating substrate, and the airflow passage (200a) penetrates at least one end along the longitudinal direction of the aerosol generating substrate. For example, the airflow passage (200a) penetrates one end along the longitudinal direction of the aerosol generating substrate. For example, the airflow passage (200a) penetrates both ends along the longitudinal direction of the aerosol generating substrate. The airflow can flow from one end of the aerosol generating substrate to the other end of the aerosol generating substrate along the longitudinal direction. In this way, the airflow formed by the air carrying the aerosol can flow more smoothly, and the airflow flow resistance is reduced, so the inhalation resistance during the inhalation process can be significantly reduced, thereby improving the inhalation experience.

[0109] In one embodiment, with reference to FIGS. 9 to 11, the airflow passage (200a) may be formed inside the aerosol generating substrate or on the outer surface of the aerosol generating substrate.

[0110] In one embodiment, referring to FIG. 9, the airflow passage (200a) is a straight airflow passage (200a) that extends along a straight line. The straight airflow passage (200a) is easy to mold, which can reduce the difficulty of manufacturing. The flow resistance of the airflow within the straight airflow passage (200a) is relatively small.

[0111] In one embodiment, with reference to FIG. 10, the airflow passage (200a) is a curved airflow passage (200a), and at least some of the hole sections of the curved airflow passage (200a) are curved rather than curvature. The curved airflow passage (200a) can significantly extend the flow path of the airflow without significantly increasing the length of the aerosol generating substrate, thereby extending the contact time between the airflow and the hole wall of the curved airflow passage (200a), and thus improving the extraction rate of the aerosol.

[0112] In one embodiment, referring to FIG. 11, the curved airflow passage (200a) is spiral. That is, the three-dimensional shape of the curved airflow passage (200a) is a spatial spiral. For example, in the extrusion process, the curved airflow passage (200a) of the extrusion substrate (200) is formed by rotating the extrusion mold (113). A line connecting any point of the spiral curved airflow passage (200a) and the starting point has an angle of inclination with respect to its axis. The spiral curved airflow passage (200a) can significantly extend the flow path of the airflow, thereby allowing the aerosol to be deposited from the aerosol generating substrate into the curved airflow passage (200a). By improving the flow velocity of the aerosol within the aerosol generating substrate, the impact force of the airflow can be improved, allowing the aerosol to be mixed uniformly, thereby improving the uniformity of the aerosol and enhancing the user's inhalation experience.

[0113] It should be understood that the extrusion substrate (200) is a semi-finished product of the aerosol generating substrate, and the extrusion substrate (200) has the same shape as the aerosol generating substrate, and if the aerosol generating substrate has an airflow passage (200a), the extrusion substrate (200) also has the same airflow passage (200a).

[0114] The cross-sectional shape of the airflow passage (200a) located inside the aerosol generating substrate is not limited, for example, the cross-sectional shape may be circular, polygonal (including but not limited to triangles, squares, rhombuses, etc.), elliptical, track-shaped, or irregular, where irregular refers to a symmetrical or asymmetrical shape other than the shapes listed above.

[0115] The cross-sectional shape of the airflow passage (200a) located on the outer surface of the aerosol generating substrate may be semicircular, semi-elliptical, polygonal, or irregular, where irregular refers to a symmetrical or asymmetrical shape other than the shapes listed above.

[0116] The number of airflow passages (200a) is not limited, and the airflow passages (200a) are one or more. The number of more refers to two and more than two.

[0117] It needs to be explained that micropores exist within the aerosol-generating substrate, and for example, in the case of an aerosol-generating substrate of a particle aggregate, the gaps between particles constitute micropores; however, the airflow passage (200a) of the present application is different from micropores, and the airflow passage (200a) of the present application belongs to pores in a macroscopic sense, while micropores belong to pores in a microscopic sense, and the size, such as the cross-sectional area and length of the airflow passage (200a), is much larger than that of micropores. Since the airflow passage (200a) is mainly processed by, for example, an extrusion mold (113), the size, such as the cross-sectional area and length of the airflow passage (200a), can be changed according to design requirements, whereas the size of the micropores is determined by the gap between particles, for example, the mixed material (200') is a granular raw material, and the extruded product of the mixed material (200') has micropores, and the size, such as the cross-sectional area and length of the micropores, is difficult to significantly change through the processing method.

[0118] In one embodiment, the step of performing extrusion molding on the mixed material (200') is,

[0119] The method includes the step of performing extrusion molding of the mixed material (200') through the extruder (110).

[0120] The mixed material (200') of the embodiment of the present application may include a plant raw material, an additive raw material, a smoke-generating raw material, an adhesive raw material, and a fragrance raw material. Here, the plant raw material, the additive raw material, and the adhesive raw material are solid raw materials, and the smoke-generating raw material and the fragrance raw material are liquid raw materials.

[0121] The plant raw material is intended to generate an aerosol upon heating. The additive raw material is intended to provide structural support to the plant raw material. The smoke-generating raw material is intended to generate smoke upon heating. The adhesive raw material is intended to bond the component raw materials together. The fragrance raw material is intended to provide a characteristic scent. In this way, the plant raw material and the smoke-generating raw material can ensure the amount of aerosol generated, and the fragrance raw material can enhance the release of scent during the inhalation process, thereby improving the user experience. The additive raw material can not only improve the fluidity of the mixed material (200') but also cause the aerosol-generating substrate to exhibit a porous structure, thereby facilitating the extraction and flow of the aerosol. The adhesive raw material ensures that the plant raw material and the additive raw material form a stable mixture, thereby preventing the structure from becoming loose.

[0122] For example, the plant raw material may be one or a combination of multiple types of powders formed after grinding tobacco leaf raw material, tobacco leaf fragments, tobacco stalks, tobacco powder, aromatic plants, etc. The plant raw material is the core source of the fragrance, and endogenous substances within the plant raw material can generate physiological satisfaction in the user; physiological satisfaction is obtained by endogenous substances, such as alkaloids, entering the human bloodstream and stimulating the pituitary gland to produce dopamine.

[0123] For example, the additive raw material may be one or a combination of inorganic fillers, lubricants, and emulsifiers.

[0124] Here, the inorganic filler comprises one or a combination of multiple of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic filler can provide a skeletal support role to the plant raw material, and at the same time, since the inorganic filler also has fine pores, it can improve the porosity of the aerosol-generating substrate, thereby improving the aerosol release rate. The lubricant comprises one or a combination of multiple 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 raw material powder, reduce friction between the plant raw material powders, make the overall density of the plant raw material powder distribution more uniform, reduce the pressure required during the extrusion molding process, and reduce wear of the extrusion mold (113). The emulsifier comprises one or a combination of multiple of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can reduce the loss of aromatic substances during storage to a certain extent, increase the stability of aromatic substances, and improve the sensory quality of the product.

[0125] For example, the fuming agent ingredients are monoalcohols (e.g., menthol), polyalcohols (e.g., propylene glycol, glycerol, triethylene glycol, 1,3-butanediol, and tetraethylene glycol), polyalcohol esters (e.g., glyceryl triacetate, triethyl citrate, glyceryl diacetate mixture, triethyl citrate, benzyl benzoate, glyceryl tributyrate), monocarboxylic acids, dicarboxylic acids, polycarboxylic acids (e.g., lauric acid, myristic acid), or aliphatic esters of polycarboxylic acids (e.g., dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butanediol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, triacetin, meso-erythritol, glycerol diacetate mixture, diethyl It may include one or a combination of multiple of caprylate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, and lauryl acetate.

[0126] For example, the adhesive raw material serves to bond the component materials by wetting the interface with the component raw material to create close contact and generate intermolecular attractive forces, such as bonding powders, liquids, etc. The adhesive raw material may be a natural plant extract or a nonionic modified viscous polysaccharide, and includes one or a combination of multiple of tamarind polysaccharides, guar gum, and modified cellulose (e.g., carboxymethyl cellulose). The adhesive is intended to bond particles together, prevents the particles from easily scattering, improves the water resistance of the aerosol-generating substrate, and is harmless to the human body.

[0127] For example, the flavoring raw material is intended to provide a characteristic scent and is, for example, a solid or liquid substance of hay scent, roasted sweet scent, or nicotine. The flavoring raw material may include one or a combination of multiple of tobacco or other plants, aromatic plant extracts, concrete, essential oils, and refined oils, and the flavoring raw material may include a single aromatic substance and may include, for example, one or a combination of multiple of megastimatrienone, neophytodiene, geraniol, nerol, etc.

[0128] For example, in 100 parts by weight of a mixture (200'), the plant raw material is 30 to 90 parts, the additive raw material is 1 to 15 parts, the fuming agent raw material is 5 to 30 parts, the adhesive raw material is 1 to 10 parts, and the fragrance raw material is 1 to 15 parts.

[0129] In one embodiment, the mixed material (200') is at least one of granular, powdered, or paste-like.

[0130] For example, the particle size of the granules may be 75 μm to 3000 μm (including 75 μm and 3000 μm), and the particle size of the powder may be smaller than the particle size of the granules.

[0131] Additionally, when the liquid content is high, the solid raw material and the liquid raw material may combine to form a paste, and since the paste-like mixture (200') is in a form closer to a solid (i.e., the mixture (200') does not flow), the paste-like form may be considered as the solid of the embodiment of the present application.

[0132] The mixed material (200') in granular and powder form can improve the smoothness, continuity, and stability of the supply and improve the stability of the extrusion pressure, thereby improving the stability of the extrusion substrate (200), which can improve production efficiency and the yield rate, and compared to pressure feeding (supplying the mixed material (200') as a single, relatively large lump), it can reduce stress concentration in the supply port (114) and extend the service life of the extruder (110).

[0133] In one embodiment, the material comprises a solid raw material and a liquid raw material, and the step of supplying the material is

[0134] It includes the step of dividing solid raw materials and liquid raw materials into two modules and supplying them separately.

[0135] That is, the solid raw material and the liquid raw material are divided into two independent modules before supply, and after the solid raw material and the liquid raw material are supplied, they are mixed in the barrel (111) of the extruder (110).

[0136] The advantage of supplying solid and liquid raw materials by dividing them into two modules is that it can reduce the pretreatment cost of the mixed material (200'), ensure the continuity of the production process, improve production efficiency, and at the same time improve the consistency and uniformity of the product.

[0137] In some embodiments, the step of dividing the solid raw material and the liquid raw material into two modules and supplying each may include the step of adding the solid raw material; and the step of adding the liquid raw material to the solid raw material when the solid raw material moves to an additional location of the liquid raw material along the material transport direction.

[0138] That is, first, a solid raw material is added to the extruder (110), and after the solid raw material enters the barrel (111) of the extruder (110), it moves along the material transport direction toward the location of the extrusion mold (113). When the solid raw material moves along the material transport direction toward the location of the liquid raw material addition, the liquid raw material is added to the extruder (110) so that the liquid raw material and the solid raw material are mixed within the barrel (111) of the extruder (110).

[0139] In addition, the additional amount and additional speed can be determined according to the production efficiency of the extruder (110) and the ratio of each raw material of the mixed material (200').

[0140] For example, referring to FIGS. 2 to 4, regarding a plurality of supply ports (114) installed in an extruder (110), the liquid raw material supply port (114) is located downstream along the material transport direction of the solid raw material supply port (114), and for example, the supply port (114) corresponding to the mixed material (200') shown in FIGS. 2 to 4 is the solid raw material supply port (114), and the other supply port (114) located downstream along the material transport direction of the supply port (114) is the liquid raw material supply port (114).

[0141] The extruder (110) primarily relies on the rotation of the screw (112) to deliver the mixed material (200'), and since the space between the screw (112) and the inner wall of the barrel (111) of the extruder (110) is 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), and if the liquid material is added first, the liquid material is prone to leaking through the gap, so the solid material is added first, and when the solid material moves along the material transport direction to the location where the liquid material is added, the leakage of the liquid material can be effectively avoided.

[0142] In some embodiments, the material comprises a solid raw material and a liquid raw material, and the step of supplying the material may include the step of pre-mixing the solid raw material; the step of adding the liquid raw material to the solid raw material after pre-mixing to form a powder slurry; and the step of supplying the powder slurry.

[0143] That is, the solid raw material and the liquid raw material are divided into two independent modules before supply, and after the solid raw material and the liquid raw material are pre-mixed, the solid raw material is pre-mixed first, then the liquid raw material is added to the pre-mixed solid raw material to form a powder slurry after mixing, and then the powder slurry is supplied.

[0144] The extruder (110) mainly relies on the rotation of the screw (112) to deliver the mixed material (200'), and since the space between the screw (112) and the inner wall of the barrel (111) of the extruder (110) is 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), and if the liquid raw material is put directly into the extruder (110), the liquid raw material is prone to leaking through the gap, so the liquid raw material is added to the solid raw material after being pre-mixed to form a powder slurry, and the powder slurry is supplied to effectively avoid leakage of the liquid raw material.

[0145] In some embodiments, the step of supplying materials may include the step of mixing materials to form a slurry; and the step of supplying the slurry.

[0146] That is, materials such as plant raw materials, additive raw materials, fuming agent raw materials, adhesive raw materials and fragrance raw materials are pre-mixed to form a slurry, and then the slurry is put into an extruder (110) to perform extrusion molding.

[0147] The advantage of first mixing raw materials to form a slurry and then supplying the slurry is that the mixed materials (200') have better consistency, ensuring the continuity of the production process and improving production efficiency, while also improving the consistency and uniformity of the product.

[0148] In some embodiments, the step of supplying materials may include the step of mixing materials to form a slurry; the step of forming a granular slurry through a granulation method of the slurry; and the step of supplying the granular slurry.

[0149] That is, raw materials such as plant raw materials, additive raw materials, fuming agent raw materials, adhesive raw materials, and fragrance raw materials are pre-mixed to form a slurry, and then the slurry is granulated to form a granular slurry of uniform size, and then the granular slurry is put into an extruder (110) to perform extrusion molding.

[0150] The advantage of first mixing raw materials to form a slurry, then forming a granular slurry through a granulation method, and then supplying the granular slurry is that it improves the smoothness, continuity, and stability of the supply of the mixed material (200'), and improves the stability of the base pressure, thereby improving the stability of the shape of the extrusion substrate (200), thereby improving production efficiency and the yield rate, reducing stress concentration at the supply port compared to a pressure feeder, and extending the service life of the extruder (110).

[0151] The granulation method can be varied, and for example, it can be formed into granules through an extrusion spherical granulation method. The extrusion spherical granulation method involves mixing the solid raw material and the liquid raw material of the mixed material (200') into a slurry, then extruding the slurry into a strip shape, cutting it to form rod-shaped small particles, and finally sphericalizing the rod-shaped small particles to form granules.

[0152] Except for extruded granules, granules can be formed by adopting methods such as fluid granules, stirred granules, and dry extrusion granules. When such granulation methods are selected, the mixed material (200') does not need to be mixed first to form a slurry, and since the solid raw material and the liquid raw material are mixed at the same time as granulation, the manufacturing process can be shortened and production efficiency improved.

[0153] More preferably, the granular particle size may be 75 μm to 3000 μm.

[0154] It must be explained that the granulation described above is merely for describing the method of manufacturing the granular mixed material (200'), and does not mean that the method of manufacturing the aerosol generating substrate of the present application must necessarily include the step of granulation when selecting the granular mixed material (200'). That is, granulation can be performed separately from the manufacturing method of the present application and can be directly added to the granular mixed material (200') when supplied.

[0155] In one embodiment, referring to FIG. 4, the extrusion direction of the extrusion molding is a horizontal direction.

[0156] Horizontal extrusion refers to the extrusion mold (113) at the outlet of the extruder (110) being installed horizontally so that the extrusion substrate (200) is extruded in a horizontal direction, or the extrusion direction of the extrusion substrate (200) is parallel to the horizontal plane.

[0157] For an extrusion substrate (200) forming a spiral airflow passage (200a), the extrusion substrate (200) can enter a transport device directly after being extruded from an extruder (110) and undergoing rotation, and horizontal extrusion can reduce the direct release of stress generated after rotation of the extrusion substrate (200) (the generated stress can be removed through heating), thereby improving the yield of the aerosol generating substrate having a spiral airflow passage (200a).

[0158] In one embodiment, with reference to FIG. 2 and FIG. 3, the extrusion direction of the extrusion molding is a vertical direction.

[0159] The vertical direction indicates that the extrusion mold (113) of the extruder (110) outlet is installed facing downward, so that the extrusion substrate (200) is extruded along the direction of gravity or the extrusion direction of the extrusion substrate (200) is perpendicular to the horizontal plane.

[0160] In the case of an extrusion substrate (200) forming a direct airflow passage (200a), vertical extrusion can improve the yield rate, lower the input cost of the extruder (110), and also reduce the occupied area of ​​the extruder (110).

[0161] In one embodiment, the extrusion direction of the extrusion molding is the inclined direction.

[0162] Inclined extrusion refers to the extrusion mold (113) at the outlet of the extruder (110) being installed at an angle such that the angle between the extrusion direction of the extrusion substrate (200) and the horizontal plane is greater than 0° and less than 90°.

[0163] Inclined extrusion can not only reduce the extrusion pressure of the mixed material (200'), but also facilitate the space design of other devices.

[0164] In one embodiment, with reference to FIGS. 5 and 6, the extrusion mold (113) may be a single extrusion mold (113), that is, the lower mold (1131) at the outlet of the extruder (110) is one, and the discharge end of the lower mold (1131) is equipped with a single die (1132), and the mixed material (200') may form an extrusion substrate (200) having an airflow passage (200a) after passing through the die (1132).

[0165] In one embodiment, referring to FIG. 7, the extrusion mold (113) may be a single mold multi-die mold, that is, the lower mold (1131) at the outlet of the extruder (110) is one, and the discharge end of the lower mold (1131) is equipped with a plurality of dies (1132), and the mixed material (200') passes through the plurality of dies (1132) and simultaneously forms a plurality of extrusion substrates (200). When the size of the screw (112) of the extruder (110) is relatively large, a single mold multi-die mold can be selected, which can improve production efficiency and is more suitable for mass production.

[0166] In one embodiment, referring to FIG. 8, the extrusion mold (113) may be a multi-mold multi-die mold, that is, a plurality of lower molds (1131) are connected to the switching joint (116) of the outlet of the extruder (110), and a plurality of dies (1132) are installed at the discharge end of each lower mold (1131), and after the mixed material (200') passes through the dies (1132) of each lower mold (1131), a plurality of extrusion substrates (200) are formed simultaneously. When the size of the screw (112) of the extruder (110) is relatively large, a multi-mold multi-die mold may be selected, which can improve production efficiency and is more suitable for mass production.

[0167] In one embodiment, the manufacturing method is,

[0168] It includes the step of cutting the extruded substrate (200) into sections of medium of a predetermined length.

[0169] Referring to FIGS. 2 to 4, the extrusion substrate (200) can be cut through the cutting tool (121) of the cutting device (120) so that the extrusion substrate (200) reaches a preset length. By doing so, the extrusion substrate (200) of the preset length can be applied to the packaging device (130) in the future, thereby reducing the requirements for the device in the future.

[0170] It can be understood that the specific numerical value of the preset length is not limited, and the preset length can be set according to the case of the aerosol generating substrate or manufacturing device (100).

[0171] In some embodiments, the extruded substrate (200) obtained through extrusion exhibits a continuous structure. That is, during the extrusion process, the extruded substrate (200) is continuously extruded so that the extruded substrate (200) exhibits a continuous structure. Continuous extrusion can improve extrusion efficiency, and subsequently, the extruded substrate (200) is cut to a predetermined length to reduce its length.

[0172] In some embodiments, the extrusion substrate (200) exhibits a segmented structure of a preset length. That is, during the extrusion process, the extrusion substrate (200) naturally separates when it reaches a preset length. For example, when the extrusion substrate (200) reaches a preset length, it may reach a threshold value on its own and detach from the extrusion mold (113). Thus, the preset length of the extrusion substrate (200) may be the length of the aerosol-generating substrate, and the extrusion substrate (200) may not be cut, thereby saving the cutting device (120) and reducing equipment costs.

[0173] The cutting tool (121) cuts the extruded substrate (200) through physical or non-physical contact.

[0174] Physical contact refers to a cutting tool (121) directly contacting the extrusion substrate (200) to cut the extrusion substrate (200). For example, the cutting tool (121) may be a roller knife, a cutting disc, a wire cutting tool, a roll cutting tool, or a press tool.

[0175] Non-physical contact refers to cutting the extrusion substrate (200) without the cutting tool (121) needing to be in direct contact with the extrusion substrate (200). For example, the cutting tool (121) emits a laser, plasma, air knife, or water jet and cuts the extrusion substrate (200) through the laser, plasma, air knife, or water jet.

[0176] The manufacturing apparatus (100) adopted in the embodiments of the present application may be for the manufacturing method of the embodiments of the present application, and the description of the manufacturing apparatus (100) embodiment is similar to the description of any one embodiment of the manufacturing method and has the same beneficial effect as the manufacturing method embodiment. Technical details not disclosed in the manufacturing method of the embodiments of the present application should be understood by referring to the descriptions of the extruder (110) and cutting device (120) embodiments of the embodiments of the present application.

[0177] For example, in one embodiment, the manufacturing method includes the step of correcting the shape of the extruded substrate (200). Correction refers to correcting the circumference and / or straightness of the extruded substrate (200) through a jig. Straightness refers to the degree of curvature in the longitudinal direction of the extruded substrate (200).

[0178] Since the texture of the extruded substrate (200) obtained through extrusion is relatively soft, during the manufacturing process of the extruded substrate (200), deformation may occur in the circumference of the extruded substrate (200) and / or bending may occur in the longitudinal direction of the extruded substrate (200). For example, during the process in which the cutting device (120) cuts the extruded substrate (200), deformation may occur in the circumference of the extruded substrate (200) and / or bending may occur in the longitudinal direction of the extruded substrate (200), so that the circumference and / or straightness of the extruded substrate (200) can be corrected through a jig.

[0179] It should be explained that shape correction of the extruded substrate (200) may be performed if any shape correction is required after step S102, and shape correction of the extruded substrate (200) may be performed once or multiple times during the entire manufacturing process of the aerosol-generating substrate. For example, shape correction of the extruded substrate (200) may be performed before and / or after cutting.

[0180] In one embodiment, the manufacturing method is,

[0181] It includes the step of wrapping a wrapping layer on the outer surface of an aerosol-generating substrate.

[0182] A wrapping layer can be wrapped around the outer surface of an aerosol-generating substrate through a packaging device (130), and the aerosol-generating substrate can be protected through the wrapping layer.

[0183] The wrapping layer comprises one or a combination of multiple materials, such as fiber paper, metal foil, metal foil composite fiber paper, polyethylene composite fiber paper, PE (Polyethylene), and PBAT (Polybutylene Adipate Terephthalate), but is not limited thereto.

[0184] In some embodiments, a wrapping layer is wrapped around the outer surface of an aerosol-generating substrate, and then combined with a functional section to form an aerosol-generating product.

[0185] In some other embodiments, an aerosol generating substrate may first be combined with a functional section, and then a wrapping layer may be wrapped around both the outer surface of the aerosol generating substrate and the functional section to form an aerosol generating product.

[0186] In another embodiment, a wrapping layer may be first wrapped on the outer surface of an aerosol-generating substrate, and then combined with a functional section and wrapped again to form an aerosol-generating product. That is, the outer surface of the aerosol-generating substrate may be wrapped with multiple layers of wrapping layer.

[0187] In the description of this application, the reference terms “in one embodiment,” “in some embodiments,” “in another embodiment,” “in yet another embodiment,” or “exemplarily,” etc., mean that the specific features, structures, materials, or features described by combining the embodiments or examples are included in at least one embodiment or example of this application. In this application, exemplary expressions of the terms may not mean the same embodiment or example. Furthermore, the specific features, structures, materials, or features described may be combined in a suitable manner among any one or more embodiments or examples.

To those skilled in the art, the present application may be subject to various modifications and variations. Any modification, equivalent substitution, and improvement made within the spirit and principles of the present application shall be deemed to be included within the scope of protection of the present application.
