Description

A heat-not-burn aerosol-generating base material and its product and preparation method

This application claims the priority of the Chinese patent application submitted to the State Intellectual Property Office on January 14, 2022, the application number is 202210041854.9, and the invention title is "Aerosol-generating product and its preparation method", the entire content of which is incorporated by reference In this application.

technical field

The invention relates to a tobacco product and a preparation method thereof, in particular to a heat-not-burn aerosol generating base material, its product and a preparation method.

Background technique

With the improvement of people's health awareness and the change of consumption concept, the advancement of science and technology and the acceleration of commodity upgrading, the needs and concerns of tobacco consumers are constantly changing. At the same time, affected by factors such as tobacco control, the development of traditional cigarettes is restricted. , the emergence and development of new tobacco has become inevitable, and heat-not-burn aerosol-generating products are one of them.

The basic principle of heat-not-burn aerosol-generating products is to cause the volatilization of low-boiling components of the aerosol-generating base material in the aerosol-generating products by heating the non-burning aerosol-generating products; the heating temperature of the heating-not-burning aerosol-generating products is Below 500°C, which is far lower than the combustion temperature of traditional cigarettes as high as 800°C, so it can greatly reduce a variety of harmful components produced by burning at high temperatures.

Typical prior art forms of heat-not-burn aerosol-generating products mainly include flake type and particle type. As shown in Figure 1, the sheet-type technology, such as the Chinese invention patent with publication number CN113163863A, discloses an aerosol-generating product, which may contain up to 200 aerosol-generating strips 2. Too many aerosol-generating strips often lead to more gaps in the aerosol-generating article. When the aerosol-generating article is inserted into the heating device for heating, due to the existence of too many gaps, the thermal conductivity between the sheets is poor, resulting in When the user inhales sheet-type aerosol products, the amount of aerosol generated in the first few mouthfuls is small, so it takes a long time to warm up to release a continuous and large amount of uniform aerosol; Produced products have a high moisture content, and the temperature of the aerosol gas generated during the heating process will be high. Therefore, the aerosol produced product also needs to include a structural design of a cooling section; in addition, the sheet combination is directional, so the heating device When the flat heating plate is inserted into the aerosol generating product, it must have certain directional requirements. When the flat heating plate and the sheet are combined at 90°, the flat heating plate will be more difficult to insert into the aerosol generating product. In addition, in terms of manufacturing process, sheet-type aerosol-generating products need to pulverize aerosol-generating raw materials, mix aerosol generating agents, aerosol stabilizers, etc. The process is not only complicated, but also expensive.

As shown in Figure 2, the particle-type technology, such as the Chinese invention patent with the publication number CN109512022A, discloses a method for preparing an empty tube-filled heat-not-burn smoking product with a sealing film. Shaped, filamentous, filamentary and granular mixture or honeycomb smoking material 4 is packaged in a circular hollow tube. Due to the particle-type aerosol-generating products, the gaps between the particles are large, and their thermal conductivity is poor; and the heating parts of heating appliances on the market are sheet-shaped and needle-shaped, and the particle-type aerosol-generating products are inserted into the sheet-shaped When the heating part of the type or needle-shaped heating device is heated, the heat conduction effect between the heating part and the heated particle-type aerosol-generating product is poor; in addition, due to the particle state, the end of the particle-type aerosol-generating product needs to be sealed. However, due to its granularity, it is not easy to be packaged, and supports or other methods are required inside the product to block the particles to prevent the particles from loosening.

In view of the problems of the above-mentioned prior art, the present invention and its embodiments are proposed below.

Please refer to FIG. 3 and FIG. 4 . FIG. 3 and FIG. 4 are schematic cross-sectional views of an aerosol generating substrate 30 in different directions according to an embodiment of the present invention. FIG. 3 is a schematic diagram of the internal structure of the cross section of the aerosol generating substrate 30 , and FIG. 4 is a schematic diagram of the internal structure of the longitudinal section of the aerosol generating substrate 30 . In this embodiment, the aerosol-generating substrate 30 is a round rod-shaped body with a porous and loose structure inside. The porous and loose structure is the coexistence of crystal blocks and fiber filaments, and there are gaps between the crystal blocks. The above-mentioned gaps are arranged in an uneven and irregular state in space. In this embodiment, the aerosol generating substrate 30 generates aerosol when heated, and the generated aerosol can pass through these internal irregular gaps, so as to be inhaled by the smoker. It can be understood that the aerosol-generating substrate 30 is not limited to a round rod-shaped body, as long as it has the above-mentioned internal structural features and falls within the scope of protection of the present invention.

The interior of the aerosol-generating substrate 30 described in this embodiment has a porous and loose structure. During the drying process of preparing the aerosol-generating substrate 30, the expansion agent in the raw material is heated to generate gas, which causes aerosol generation. Before the expansion of the base material 30 and the aerosol containing a large amount of water before drying, the water in the base material 30 is evaporated due to heat. The gaps of the porous and loose structure formed by the puffing technology in this embodiment are in a non-uniform and irregular state in space. Compared with the prior art flake type and particle type, the void ratio described in this embodiment is smaller, and the internal Although the gap in the gap can allow the aerosol generated by heating to pass through, there is no through hole from one end of the aerosol generating substrate 30 to the other end, so when the aerosol generating substrate 30 of this embodiment is not heated, it is different from the existing heating or burns smoke. In comparison, the suction resistance is greater.

Please refer to FIG. 5 and FIG. 6 . FIG. 5 and FIG. 6 are schematic cross-sectional views of the aerosol-generating substrate 30 in different directions after being heated in this embodiment. FIG. 5 is a schematic cross-sectional internal structure diagram of the aerosol-generating substrate 30 after heating, and FIG. 6 is a schematic diagram of the longitudinal-sectional internal structure of the aerosol-generating substrate 30 after heating. When the aerosol-generating substrate 30 is heated, the internal voids will gradually increase, and the volatilization of the aerosol, flavors and fragrances will also cause the porosity to increase to a certain extent, and the suction resistance will gradually decrease. When the aerosol-generating substrate 30 is heated and sucked, the suction resistance of the first mouth is relatively large, which may exceed 1.5KPa, may exceed 2.0KPa, or may exceed 3.0KPa, and continue to pump after the first mouth. After 3-4 puffs, the suction resistance decreases to about 1.0KPa, or even less than 1.0KPa, which is more suitable for smokers. The aerosol generating substrate 30 of the present embodiment has the following characteristics: 1. Different suction resistances are arranged under different heating times; 2. With the heating time, the suction resistance gradually decreases; Compared with the flake type and granular type, the suction resistance is greater; 4. With the heating time, compared with the existing flake type and granular type, the suction resistance is greater than or equal to that of the existing flake type and granular type. .

In this embodiment, the aerosol-generating substrate 30 may be a porous and loose structure in which the crystal blocks are adhered to each other to form an integrated structure. The internal voids are small, the heat conduction effect is good, and the heat is uniform. Compared with the flake-type and particle-type aerosol-generating substrates of the prior art, the gaps in the prior art are larger, so the heat conduction effect is not good; the interior of the aerosol-generating substrate 30 of the present invention is loose and porous, and the pores are smaller. It can achieve the advantages of good heat conduction effect and uniform heating.

In the above embodiments, the aerosol-generating substrate 30 contains an aerosol-generating agent, and the aerosol-generating agent generates an aerosol when heated. When the aerosol-generating base material 30 is heated by the heating element of the heating device, the aerosol-generating agent in the aerosol-generating base material 30 reaches the boiling point and evaporates into an aerosol, which can be inhaled by the smoker.

The preparation method of the aerosol-generating substrate 30 of the present invention is disclosed below. The preparation method of the present invention is realized from the aspects of the raw material composition, molding and baking process of the aerosol-generating substrate 30 .

In terms of raw material composition, the raw material components for the preparation of the aerosol generating substrate 30 include bulking agent, a large amount of water and plant raw materials. The expanding agent component in the raw material is heated to generate gas (carbon dioxide, CO2) during the baking process, and the gas formed inside causes the raw material to expand. When the gas is released, the inside of the aerosol-generating substrate 30 becomes porous and loose. In addition, a large amount of water contained in the aerosol-generating substrate 30 evaporates during the baking process so that the inside of the aerosol-generating substrate 30 is porous and loose.

In the molding process of the aerosol generating substrate 30 of the present invention, firstly, after the plant material is crushed, various flavors and fragrances, tobacco extracts, aerosol generating agents, aerosol substrate forming agents, and aerosol substrate expanding agents are mixed. , aerosol slow-release agent and water, etc., are prepared into a paste-like material, and then formed into an aerosol-generating substrate 30 before drying through a molding process. Wherein, various plant raw materials are the main carriers of the aerosol generating substrate 30; various flavors and fragrances and tobacco extracts provide various tastes of different flavors for the aerosol generated; the aerosol generating agent is heated on the aerosol generating substrate 30 Aerosol is generated during the process; the aerosol substrate forming agent can allow the paste-like material to form the required shape of the aerosol-generating substrate 30 and penetrate into the crystal block and the inside of the fiber filament; the swelling agent can be used in the air Gas is generated when the sol-generating substrate 30 is dried or heated during the drying process, making the inside of the paste-like material porous, and then the aerosol-generating substrate 30 with a porous structure can allow aerosols to pass through. Since a large amount of water is added to the raw material formula of the aerosol-generating base material 30, the weight ratio of the water to the total raw materials can reach 30-60%. The material 30 forms a porous and loose structure. In the embodiment of the present invention, the baking process adopted includes microwave puffing baking process, vacuum drying baking process, vacuum freeze-drying baking process, and high-frequency induction baking process, which can make the aerosol-generating substrate 30 dry during the baking process. Medium puffing forms a porous and loose structure.

According to the disclosure above, in the preparation example of the aerosol-generating substrate 30 of the present invention, firstly, the plant material of the aerosol-generating substrate 30 is pretreated, and the pretreatment of the plant material is mainly through the natural fermentation of the plant material or Fermentation with fermented enzymes reduces the miscellaneous gas in the plant raw materials and improves the aftertaste; then, prepares various raw materials for preparing the aerosol-generating base material 30 into a paste-like material to prepare for subsequent molding of the aerosol-generating base material 30; Furthermore, the paste-like material is prepared into a rod-shaped aerosol-generating substrate 30 through a fixture device; finally, the paste-like aerosol-generating substrate 30 is dried and puffed through a baking process, A large amount of water in the aerosol-generating substrate 30 is evaporated to obtain a loose aerosol-generating substrate 30 .

During the drying process, the drying parameters need to be well controlled so that the aerosol-generating substrate 30 has proper hardness and porosity. The baking temperature should not be too high, too high baking temperature will cause the hardness of the aerosol generating substrate 30 to be too large, making it difficult for the aerosol generating substrate 30 to be inserted into the heating device for suction, and at the same time, the aerosol generating substrate 30 will be inhaled. Tobacco extracts and various flavors and fragrances volatilize in large quantities, and the taste becomes poor. Selecting a suitable baking process can ensure that the aerosol generating substrate 30 has a certain porosity, so that the aerosol can pass through the inside of the aerosol generating substrate 30 smoothly during the heating and suction process.

The raw material composition of the aerosol generating substrate 30 of the present invention is disclosed below.

The raw materials of the aerosol generating substrate 30 include plant raw materials, tobacco extracts, flavors and fragrances, aerosol generating agents, aerosol substrate forming agents, aerosol substrate expanding agents, aerosol slow-release agents and water.

In other embodiments, when matching heating appliances with components without heating chips, metal materials or magnetic materials can be added to the raw material composition of the above-mentioned aerosol generating substrate 30, and the principle of high-frequency response is used during the baking process. The aerosol generating substrate is dried. Since the aerosol-generating substrate 30 of this embodiment is provided with a metal material or a magnetic material inside, when the aerosol-generating substrate 30 is inserted into a heating device without a heating sheet for heating, it can be heated by the Hall Effect. The aerosol-generating substrate 30 heats, thereby providing the smoker with a puff.

The plant raw materials of this embodiment, when picked, are rich in starch, protein, organic acids, aroma substances, etc., and have defects in varying degrees in their internal quality, such as heavy green miscellaneous gas and strong irritation. The molecular structure of various untreated plant materials is relatively large, and the taste of the macromolecular structure itself is relatively strong, and it is difficult for the taste of flavors and fragrances to cover up the taste of the macromolecules themselves. For example, the protein content in tea leaves is 21-28%. During the heating process, it will produce a spicy feeling, increase the irritation, increase the bitterness, and produce an unpleasant protein odor.

Therefore, before preparing the paste-like material, in the first step, various plant materials of the aerosol generating substrate 30 need to be pretreated to reduce various miscellaneous gases of the plant materials.

The pretreatment of the plant material may be natural fermentation and fermentative enzyme fermentation of the plant material.

In this embodiment, the pretreatment of the plant material of the aerosol-generating substrate 30 adopts natural fermentation.

The natural fermentation of the plant raw materials is to store at least one of herbal plants, Chinese herbal medicine plants or tobacco raw materials in a warehouse with a certain temperature and humidity for a period of time to carry out natural alcoholization. The optional temperature is 18-25 ° C, and the relative humidity is at 60%～65%, the storage time is 1-3 years; due to the natural alcoholization of plant raw materials, it can promote the transformation of the internal chemical components of plant raw materials, reduce the miscellaneous gas of plant raw materials, reduce the irritation, improve the aftertaste, and further make the heating process The smoke generated by the aerosol generating substrate 30 is more mellow and delicate.

However, using the natural fermentation method of plant raw materials for alcoholization treatment takes a relatively long period and occupies a large area in the warehouse. In order to shorten the alcoholization time of plant materials, using biotechnology and using fermentation enzyme fermentation method can greatly reduce the alcoholization time.

Many studies have shown that by using the individual or comprehensive effects of various enzymes, part of the protein in the raw material can be hydrolyzed into a series of small molecule nitrogen-containing compounds, and these conversion products can undergo Maillard reactions with reducing sugars, alcohols, etc. to produce edible or tobacco flavors. The product has strong nutty aroma, sauce aroma, roasted aroma, caramel aroma, fruit aroma, tobacco aroma and Chinese herbal medicine aroma, which can effectively enrich the aroma of cigarettes and enhance the smoking experience, thereby reducing the burnt smell and miscellaneous gas in the raw materials, etc. It makes the fragrance more transparent, and can coordinate the smell of the smoke, reduce the scorched smell, etc., and make the internal chemical composition ratio of the cigarette more harmonious. In addition, short peptides and amino acids can also chemically react with phenolic compounds, pigment degradation products, lipid molecules, etc., and their products can also improve the smoking quality of cigarettes.

In other embodiments, the plant material pretreatment of the aerosol-generating substrate 30 is fermented with enzymes.

The method for fermenting the plant raw material fermenting enzyme is to carry out mixed fermentation of the fermenting enzyme and the plant raw material under a certain temperature, humidity and pH environment; the addition ratio of the fermenting enzyme is 0.001%-1%, and the fermentation temperature is 30-65°C , preferably 40-50°C, the pH value of fermentation is 5.5-10, preferably 6.5-8.5, and the fermentation time is 10-30 days; the type of fermenting enzyme used can be protease, pectinase, cellulase, lipase at least one of these.

After fermented by fermentation enzymes, the protein and other substances in the plant raw materials are degraded into other small molecular substances, such as protein can be degraded to generate short peptides, free amino acids, etc., which reduces the burnt smell and impurities produced by the macromolecular substances in the plant raw materials during the heating process. Gas, etc., coordinate various chemical components in plant raw materials to improve the aroma of smoke, thereby improving the quality of smoking.

The second step is to prepare various raw materials of the aerosol generating substrate 30 into a paste-like material to prepare for the next step of forming the aerosol generating substrate 30 .

The present invention provides an embodiment of a method for preparing the paste material of the aerosol generating substrate 30 . After the plant raw materials are fermented by fermentation enzymes, start to prepare the paste-like material of the aerosol generating substrate 30; the herbal plants, Chinese herbal medicine plants, tobacco raw materials or wood fibers fermented by the fermentation enzymes are pulverized by a pulverizer, and the pulverized grains The diameter is 10 μm-500 μm; take one or more combinations of pulverized herbal plants, Chinese herbal medicine plants, tobacco raw materials or wood fibers in proportion, and mix them uniformly to obtain pulverized and uniformly mixed plant raw materials; take the pulverized and uniformly mixed 40-80 parts of plant raw materials, 10-20 parts of tobacco extract, 30-60 parts of aerosol generating agent, 10-30 parts of flavor and fragrance, 1-5 parts of aerosol base forming agent, 1-5 parts of aerosol base expanding agent 3 parts, 1-10 parts of aerosol slow-release agent, and 30-50 parts of water are mixed and stirred together, and then stirred evenly by a mixer to form the paste-like material, which can also be called paste.

In this embodiment, when herbal plants, Chinese herbal medicine plants, tobacco raw materials or wood fibers are pulverized by a pulverizer, the pulverized plant raw material powder contains granules and fiber filaments, the particle size of the granules is 10 μm-500 μm, and the fiber filaments The outer diameter is 5 μm-30 μm, and the granular matter has an irregular shape.

In this embodiment, in the prepared paste, the aerosol generating agent (such as glycerin), essence and fragrance, and water penetrate into the interior of the above-mentioned granules and fiber filaments.

It can be seen from the above examples that the aerosol generating substrate 30 of the present invention has a large proportion of water added, and the prepared paste-like material has moderate humidity and hardness, so as not to have too little water. The function is to facilitate the formation of paste-like materials from various raw materials, so as to facilitate the filling operation in the next step-so that the paste-like materials can be extruded through an extruder; at the same time, a large amount of water in the raw materials evaporates during the drying process Finally, the micropores formed inside the aerosol-generating substrate 30 allow the aerosol generated by the aerosol-generating substrate 30 to pass through smoothly and achieve moderate suction resistance. If the moisture content of the prepared paste-like material is too low, on the one hand, it will increase the extrusion difficulty of the extrusion device, and on the other hand, it will increase the compactness of the aerosol-generating substrate 30, making it difficult for the aerosol to pass through; If the moisture content of the prepared paste-like material is too high, it is not conducive to the forming of the aerosol-generating substrate 30. Therefore, it is more appropriate for the prepared paste-like material to have a moisture content of 30-60% by weight.

The third step is to fill and shape the paste-like material of the aerosol generating substrate 30 .

The aerosol-generating base material 30 of the present invention is extruded and formed by an extruder, and the extruding method is to drive the feeding device through the driving device to extrude the paste-like material through the discharge port; cut it after extruding into strips, or After being extruded, it is wrapped with a sheet packaging material and then cut, or directly extruded into a tubular packaging material to obtain an undried aerosol generating substrate 30 .

In the prior art, there is also an aerosol-generating substrate 30 obtained by extrusion, but it cannot be mass-produced. One is that it is too hard to be inserted into a heating device for suction; The sol is more difficult to pump out.

After introducing the various embodiments of the aerosol-generating substrate forming devices 800-816 in FIGS. After the discharge port of the material forming device 800-816, before the paste-like material is sent to the tubular packaging material 40, an airgel generating device is additionally provided. The following will take the aerosol generating substrate forming device 800 shown in FIG. 7 as an example to illustrate the airgel generating device, without repeating the description of the aerosol generating substrate forming devices 802-816 in FIGS. 8 to 19 .

Please refer to FIG. 19A. FIG. 19A is a schematic structural diagram of another embodiment of the aerosol-generating substrate molding device 800 of FIG. 7; in this embodiment, the difference from the aerosol-generating substrate molding device 800 of FIG. : An airgel generating device is additionally set at the outlet 208 of the aerosol generating substrate forming device 800. The preparation of the aerosol-generating substrate 30 in this embodiment is that the paste-like material passes through the aerosol-generating substrate forming device 80, and then injects airgel into the paste-like aerosol-generating substrate through the airgel generating device, Finally, it is packed into the tubular packaging material.

In this embodiment, the airgel generating device includes a container 203, a pump 205, a pipeline 207 and a pipeline 209, wherein the container 203 is used to contain the solution, and the pump 205 is used to extract the solution in the container 203 through the pipeline 207, and through the pipeline 209 is transported to the outlet 208 of the aerosol generating substrate forming device 800.

In this embodiment, the first solution and the second solution are mixed in the container 203 . The first solution is a bio-based polysaccharide or polyamino acid solution containing carboxylate groups, and the second solution is a divalent/trivalent metal ion solution. After the first solution and the second solution are mixed, the metal ion and carboxylate are formulated In-situ interaction to form a gel through ionic cross-linking. The formed gel has a sealing and encapsulating effect.

In other embodiments, the above-mentioned first solution may also be added when preparing the paste-like material to prepare a paste-like material containing the first solution. In the process of preparing the paste-like material, since the first solution added contains water, the amount of water added during the preparation of the paste-like material can be appropriately reduced, so as to prevent the prepared paste-like material from being too thin and difficult to form. When extruding the paste-like aerosol-generating base material comprising the above-mentioned first solution in the aerosol-generating base-material molding device 800, pump 205 into the container 203 at the outlet 208 of the aerosol-generating base material molding device 800. The above-mentioned second solution is injected, and the second solution has a cross-linking reaction with the first solution in the extruded paste-like aerosol-generating substrate to generate a gel-like paste-like aerosol-generating substrate.

Because the gel has an encapsulating effect, the gel substance in the aerosol generating base material can lock the aerosol generating agent and flavor and fragrance in the aerosol generating base material at normal temperature, so that the flavor and fragrance are not easily volatilized. At the same time, because the aerosol generating agent has water absorption, the gel substance can also prevent the aerosol generating substrate from becoming damp due to absorbing moisture in the air.

When the aerosol generating substrate is heated, the aerosol generating agent in the aerosol generating substrate is vaporized to form an aerosol, and at the same time, the flavor and fragrance are mixed with the aerosol generating agent when the paste is prepared, and the aerosol generating agent is vaporized to form an aerosol Seasonal flavors and fragrances are also brought out.

In another embodiment, the first solvent of the gel is a dextrin-rich material, such as β-cyclodextrin, hydroxypropyl-β-cyclodextrin, methyl-β-dextrin, the first solvent The concentration is 5%-30%; the second solvent is adamantane-enriched substance, such as adamantane graft, 5-30%.

It should be noted that in this embodiment, the first solution and the second solution can be interchanged without affecting the effect of the aerosol-generating substrate of the present invention, that is to say, when preparing the paste-like material, add the above-mentioned first solution For the second solution, a paste-like material containing the second solution is prepared, and the container 203 contains the first solution.

The undried aerosol-generating substrate obtained in the above-mentioned embodiments of the present invention has a high moisture content, and after a subsequent drying step, the porous and loose aerosol-generating substrate 30 can be obtained, which is suitable for inserting into an appliance for heating.

The aerosol generating substrate 30 of the present invention is an integral rod shape, and the advantage of the integral aerosol generating substrate 30 is that the heat conduction effect is relatively good when the heating element of the heating device heats the substrate, and better Suction effect.

The fourth step: drying and puffing the molded paste-like material substrate through a baking process to obtain a loose aerosol-generating substrate 30 .

The drying process is a key step in the preparation process of the aerosol generating substrate 30, and the porous and loose structure of the aerosol generating substrate 30 is produced during the baking process.

As shown in FIG. 20 , FIG. 20 is a schematic structural diagram of an aerosol-generating substrate drying device 820 in a drying embodiment; the aerosol-generating substrate drying device 820 is used for low-temperature drying.

The aerosol generating substrate drying device 820 includes a box body 406, a temperature sensor 404, and a heat source 402; the heat source 402 can be electric heating, air compressor heating, electric thermocouple heating, infrared heating, ultraviolet heating, magnetic induction heating, etc. heating method.

In this drying embodiment, at least one of the undried

aerosol production substrates

110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 130, 134 obtained in the previous step One is placed in the box 406, the temperature is set at 30-80°C, preferably 45-65°C, the baking time is 60-400 minutes, and the moisture content of the baking is 5-15% of the weight of the aerosol-generating substrate , and take it out to obtain the dried heated and smokeable aerosol-generating substrate 30 .

Can contain sodium bicarbonate (NaHCO ₃ ) in the described bulking agent, sodium bicarbonate will produce chemical reaction when heated, is heated and decomposed into sodium carbonate, carbon dioxide and water, and its chemical equation is:

The aerosol generating substrate expansion agent may contain disodium dihydrogen pyrophosphate (Na ₂ H ₂ P ₂ O ₇ ) and sodium bicarbonate, and disodium dihydrogen pyrophosphate and sodium bicarbonate undergo a chemical reaction when heated to produce coke Sodium phosphate (Na ₄ P ₂ O ₇ ), carbon dioxide and water, the chemical reaction formula is:

During the baking process, the expansion agent in the raw material of the aerosol-generating substrate 30 is heated and decomposed to generate gas during the baking process, so that the base material of the paste-like material expands to increase the volume, and a paste-like paste with porous and uniform pores is formed inside. Loose tissue.

During the baking process, a large amount of water contained in the paste-like material substrate evaporates, so that the density and hardness of the aerosol-generating substrate 30 become smaller, which is suitable for insertion into a heating appliance for heating.

Wherein, the baking temperature of the aerosol-generating substrate drying device 820 is set at a low-temperature baking temperature of 30-80° C., so that the expansion agent in the paste-like material substrate can fully play its role, making the The aerosol-generating base material 30 produces porous puffy tissue inside to facilitate the passage of the aerosol; if the baking temperature is set too high, the water evaporation rate is fast, and the expansion agent of the paste-like material base material is insufficiently expanded, which is easy to Forms a dense, hardened substrate that impedes aerosol passage and insertion into heating appliance heating elements.

The raw materials of the aerosol-generating substrate 30 contain flavors, fragrances, tobacco extracts and other substances, which are easy to volatilize, change flavor and lose at high temperature, so the baking temperature should not be too high during the drying process.

Please refer to FIG. 21 , which is a schematic structural diagram of an aerosol-generating substrate drying device 822 in another drying embodiment; the aerosol-generating substrate 30 is prepared by drying with the aerosol-generating substrate drying device 822 .

The aerosol generating substrate drying device 822 adds heat convection on the basis of the aerosol generating substrate drying device 820, so that the temperature in the entire drying device is more uniform and the consistency is better.

The aerosol generating substrate drying device 822 includes a box body 410, a baking area 412, a moisture removal window 414, a reflow area 416, a partition 418, a temperature and humidity sensor 420, a heat source 422 and a fan 424; The inner partition is a baking area 412 and a reflow area 416 ; the dehumidification window 414 is set near the airflow inlet of the reflow area 416 ; the temperature and humidity sensor 420 is set at the reflow port of the reflow area 416 ;

In this drying embodiment, the undried aerosol generating substrate to be baked is put into the baking zone 412 of the aerosol generating substrate drying device 822, and the fan 424 blows the heat generated by the heat source 422 to the baking area. Zone 412 is the undried aerosol generating substrate to be baked, the hot air flow heats the undried aerosol generating substrate, and exchanges heat with the undried aerosol generating substrate, the undried aerosol generating substrate The moisture in the base material produced by drying the aerosol evaporates and is mixed into the hot air flow, and the hot air flow becomes a low-temperature air flow and a large amount of moisture is mixed with it to make the humidity relatively high; The return port flows back to the heat source 422, and then blows to the aerosol-generating substrate 30 to be baked in the baking zone 412 after being further heated, so that the temperature in the entire drying device is more uniform and the consistency is better; When passing through the temperature and humidity sensor 420 at the backflow port, the temperature and humidity sensor 420 detects the humidity in the low-temperature airflow. When the humidity is greater than the set value, the dehumidification window 414 is opened to discharge the low-temperature airflow containing a large amount of moisture out of the box body 410, thereby starting to accelerate the baking of the undried aerosol-generating substrate.

Wherein, the baking temperature of the aerosol-generating substrate drying device 822 is set to 30-80°C, preferably 45-65°C, and the baking time is 60-400 minutes, and the moisture content of the baking is reached to the weight of the aerosol-generating substrate. 5-15%, take it out to obtain the dried heated and smokeable aerosol production substrate 30.

The principle is the same as the drying embodiment of the above-mentioned aerosol-generating substrate 30. Since the paste-like material substrate contains an expanding agent and a large amount of water, the aerosol-generating substrate 30 can be fully expanded during the baking process to produce Substrate with loose porous structure.

Please refer to FIG. 22 , which is a schematic structural diagram of an aerosol-generating substrate drying device 824 in another drying embodiment; the aerosol-generating substrate drying device 824 is used to dry the aerosol-generating substrate 30 .

The aerosol-generating substrate drying device 824 bakes the undried aerosol-generating substrate by means of microwave baking according to the principle of microwave puffing, so that the aerosol-generating substrate 30 has a porous structure.

The aerosol-generating substrate drying device 824 includes a microwave box 430, a microwave generator 432, and a baking area 434; in order to reduce the air pressure in the oven, reduce the water evaporation temperature, and accelerate the drying process, the aerosol-generating substrate drying device 824 A vacuum system 436 is also provided.

The microwave frequency band selected by the aerosol-generating base material drying device 824 is the common industrial microwave frequency band of 915MHz±5MHz or 2450MHz±5MHz. 0-101KPa.

In this drying embodiment, the paste-like material substrate to be dried is placed in the baking zone 434 of the aerosol-generating substrate drying device 824, and the baking temperature is set to 30-80°C, preferably 45- 65°C, the vacuum degree is set to 0-101KPa, preferably 30-60KPa, the microwave power is adjusted according to the quantity of materials put in, and the power is adjusted to 0.8-4.0KW per kilogram of material, preferably 1.0-2.5KW, and the baking time is set to After 10-60 minutes, the moisture content is dried to 5-15% of the weight of the aerosol-generating substrate, and then taken out to obtain the dried heated and smokeable aerosol-generating substrate 30 .

In order to further optimize the microwave baking program, during the baking process, the microwave baking program can be set to turn off the microwave for a period of time after the microwave is baked for a period of time, then turn on the microwave to bake, then turn off, and cycle in turn; the preferred microwave The baking time is 1-5 minutes, and the microwave is turned off for 1-3 minutes. After the aerosol generating substrate 30 is dried, the aerosol generating substrate drying device 824 is shut down, and the aerosol generating substrate 30 is taken out.

Generally, substances are composed of polar and nonpolar molecules. Under the action of the microwave electromagnetic field, the polar molecules in the medium change from the original thermal motion state to follow the alternation of the microwave electromagnetic field to align and align. When the microwave frequency used is 2450 MHz to irradiate the paste-like aerosol-generating base material 30 with microwaves, the polar molecules in the paste-like aerosol-generating base material 30 will be arranged 2.45 billion times per second. Intense friction will be generated, thereby generating heat inside the paste-like aerosol generating substrate 30, so that electric energy can be directly converted into heat energy in the medium.

In this drying embodiment, through the radiation conduction of electromagnetic energy, when the microwave energy reaches the inside of the paste-like undried aerosol generating substrate, it is converted into heat energy, so that the paste-like undried aerosol generates inside the substrate. Water molecules absorb microwave energy, and the paste-like undried aerosol produces rapid evaporation of deep water in the substrate to form a high internal vapor pressure. Because the microwave heating speed is very fast, the paste-like undried aerosol The formation rate of the steam inside the substrate produced by the sol is higher than the migration rate of the steam, and the paste-like undried aerosol produces a vapor pressure gradient inside the substrate, and when the pressure exceeds that of the paste-like undried aerosol, the substrate material is produced When the strength of the organizational structure is sufficient, the paste-like undried aerosol is forced to expand the base material, and the expansion force of the gas is used to drive the paste-like undried aerosol to produce structural denaturation of the polymer in the base material. Therefore, the inside of the paste-like undried aerosol-generating substrate has the characteristics of a porous structure.

Moisture content has a significant effect on the ability of the raw material in the paste-like undried aerosol substrate to absorb microwave energy. The higher the moisture content in the paste-like undried aerosol substrate, the longer the evaporation time during puffing, which will affect the puffing effect and production efficiency; the lower the moisture content, the insufficient puffing internal pressure will not be generated during puffing, which reduces the paste The expansion rate of the aerosol substrate. In the embodiment of the present invention, the water content of the paste-like undried aerosol-generating base material accounts for 30-60% of the weight of the paste-like undried aerosol-generating base material, achieving a good puffing effect.

The boiling point temperature of water is related to the air pressure. Different air pressure has different boiling point of water. Under the condition of a standard atmospheric pressure of 101KPa, the boiling point temperature of water is 100°C. As the air pressure decreases, the boiling point temperature of water will decrease; when the air pressure drops Under the pressure condition of 30-60KPa, the boiling point temperature of water drops to 40-60°C.

In this drying embodiment, when the microwave box 430 is evacuated, the moisture evaporation temperature in the paste-like undried aerosol can be reduced. When the microwave box 430 is evacuated to 30-60KPa , the moisture in the paste-like undried aerosol-generated substrate reaches the evaporation temperature at 40-60°C, which further accelerates the formation speed of the steam inside the paste-like undried aerosol-generated substrate, which is beneficial to the paste Pureed undried aerosols create a puffing effect on the substrate material.

Further, in this embodiment, the microwave baking can also be carried out by combining vacuum microwave baking and atmospheric pressure microwave baking. During the microwave baking process, the aerosol-generating substrate drying device 824 is vacuum-baked for 1-5 minutes, and then the aerosol-generating substrate drying device 824 is released to an atmospheric pressure for normal Pressure microwave baking for 1-5 minutes, then carry out vacuum microwave baking on the aerosol generating substrate drying device 824 for 1-5 minutes, then switch to normal pressure microwave baking for 1-5 minutes, and so on, until the The aerosol-generating substrate 30 is dried.

Further, in this embodiment, the microwave device may also include a rotating mechanism, and the rotating mechanism may also include a placement tray, and the undried aerosol generating substrate is placed on the placement tray in the rotating mechanism, During microwave baking, the rotating mechanism drives the tray to rotate in the microwave device, so that the aerosol generating substrate can be heated evenly in the microwave device.

Baking in a microwave mode can quickly evaporate the water in the base material produced by the undried aerosol, and at the same time make the paste-like material expand rapidly, and stick together with the inner wall of the packaging material 32 to form an integral loose porous structure; The paste-like material contains a large amount of water. After the material expands and the water evaporates, a large number of micropores are formed inside the aerosol-generating substrate 30, and the porosity of the micropores reaches 40-75%.

During the baking process, the expanding agent in the raw material of the aerosol-generating substrate 30 is heated and decomposed to generate gas during the baking process, which makes the paste-like undried aerosol-generating substrate expand, increase the volume, and form a porous and uniform pore. Loose tissue. The principle of thermally decomposing the swelling agent of the aerosol-generating substrate 30 to generate gas has been described in the above-mentioned embodiments and will not be repeated here.

During the baking process, a large amount of water contained in the raw material of the aerosol-generating substrate 30 evaporates, so that the density and hardness of the aerosol-generating substrate 30 become smaller, which is suitable for heating by inserting a heating device.

In this drying example, the microwave puffing technology, the principle of lowering the boiling point of water under low pressure and the puffing effect of the puffing agent in the raw material of the aerosol generating substrate 30 are fully utilized, so that the internal tissue gaps of the aerosol generating substrate 30 are more uniform , the structure is porous and loose, the hardness of the aerosol-generating substrate 30 after drying is in the range of 0.5-2.5kgf, and the strength of inserting the heating appliance is more appropriate, which will not cause the aerosol-generating substrate 30 to harden during the baking process And the situation that the heating part of the heating appliance cannot be inserted.

In this drying example, the microwave baking temperature is also set at 30-80°C, preferably 45-65°C, which effectively preserves the flavors, fragrances, tobacco extracts and other components in the raw materials of the aerosol generating substrate 30 , so as not to make a large amount of components such as flavors and fragrances and tobacco extracts in the raw materials of the aerosol generating base material 30 volatilize, change taste, and lose, thereby ensuring the inhalation flavor of the aerosol generating base material 30 .

In the embodiment of drying the aerosol-generating substrate 30, two drying methods of microwave baking and convection baking can also be used. First, use the aerosol generating substrate drying device 824 to perform preliminary microwave baking on the undried aerosol generating substrate 30 according to the method in the above embodiment, so that the aerosol generating substrate 30 expands under the action of microwaves , while removing 10-60% of the moisture content in the undried aerosol generating substrate; taking out the semi-dried aerosol generating substrate 30, and waiting for the temperature to drop to 20-25°C; Put the dried aerosol generating substrate 30 into the aerosol generating substrate drying device 822 and dry the semi-dried aerosol generating substrate 30 to the moisture content of the aerosol according to the method in the above-mentioned embodiment. 5-15% of the weight of the base material is produced; it is taken out to obtain the dried aerosol production base material.

Combining the microwave baking of the aerosol-generating substrate drying device 824 and the thermal convection baking of the aerosol-generating substrate drying device 822 can give full play to the advantages of the two baking methods. Microwave baking has high baking efficiency and microwave puffing effect, and can quickly remove the moisture in the undried aerosol-generating substrate 30 to achieve the purpose of puffing. The aerosol generating substrate 30 can make the internal tissue structure of the dried aerosol generating substrate 30 more uniform, and the baking process is more stable and controllable.

In this embodiment of drying the aerosol-generating substrate 30, in the microwave baking step, it can also be carried out by combining vacuum microwave baking and atmospheric pressure microwave baking in the above-mentioned embodiment, and the undried After the aerosol-generating substrate 30 is expanded by microwaves to remove 10-60% of the water content, it is then baked by convection baking.

Please refer to FIG. 23 , which is a schematic structural diagram of an aerosol generating substrate drying device 826 in another drying embodiment; the aerosol generating substrate drying device 826 is used to dry the aerosol generating substrate 30 .

In this embodiment, the aerosol-generating substrate drying device 826 adopts a vacuum drying method, heats the undried aerosol-generating substrate 30 under vacuum conditions, and heats the undried aerosol-generating substrate 30. The boiling point of the moisture in 30 is lowered, which speeds up the drying speed of the undried aerosol generating substrate 30 .

The aerosol generating substrate drying device 826 includes a box body 440 , a baking area 442 , a heat source 444 and a vacuum pump system 446 .

In this drying embodiment, the undried aerosol-generating substrate 30 is placed in the baking zone 442, the baking temperature is set to 30-80°C, preferably 45-65°C, and the vacuum degree is set to 10-90KPa. It is preferably 30-60KPa, and the time is set to 30-900 minutes, and the starting equipment is used to vacuum-dry the undried aerosol generating substrate 30, wherein the vacuuming can be to start the vacuum pump to dehumidify; the moisture of the aerosol producing substrate is dried to When the weight of the aerosol-generating base material is 5-15%, the dried aerosol-generating base material 30 is taken out to obtain the dried, heated and smokeable aerosol-generating base material 30 .

Since vacuum drying belongs to static vacuum drying, the shape of the aerosol-generating substrate 30 will not be damaged. At the same time, because the drying temperature is relatively low, within the range of 30-80°C, the aerosol-generating substrate 30 will not be damaged. Hardens after drying.

During the baking process, the puffing agent in the raw material of the aerosol-generating substrate 30 is heated and decomposed to generate gas, which makes the paste-like aerosol-generating substrate 30 puff up, increasing the volume, making the volume structure soft, and forming a loose tissue with pores and uniform pores. The principle of thermal decomposition of the swelling agent of the aerosol-generating substrate 30 to generate gas has been described in the above-mentioned embodiments and will not be repeated here.

In the embodiment of drying the aerosol-generating substrate 30, two drying methods can also be adopted: microwave baking and vacuum drying. First use the aerosol generating substrate drying device 824 to perform preliminary microwave baking on the undried aerosol generating substrate 30 according to the method in the above-mentioned embodiment, so that the undried aerosol generating substrate 30 expands under the action of microwaves , and simultaneously remove 10-60% of the moisture content in the undried aerosol generating substrate 30; take out the semi-dried aerosol generating substrate 30, and wait for the temperature to drop to 20-25°C; Put the sol-generating substrate 30 into the aerosol-generating substrate drying device 826 and dry the semi-dried aerosol-generating substrate 30 until the moisture content of the aerosol-generating substrate 30 is equal to the weight of the aerosol-generating substrate 30. 5-15%; the aerosol production substrate 30 is taken out to obtain the dried aerosol production substrate 30 .

Combining the microwave baking of the aerosol-generating substrate drying device 824 and the vacuum drying and baking of the aerosol-generating substrate drying device 826 can give full play to the advantages of the two baking methods. Microwave baking has high baking efficiency and good microwave puffing effect, and can quickly remove the moisture in the undried aerosol-generating substrate 30 to achieve the purpose of puffing. The aerosol generating substrate 30, because vacuum drying belongs to static vacuum drying, so the shape of the aerosol generating substrate 30 will not be damaged, which can make the internal tissue structure of the aerosol generating substrate 30 more uniform, and the baking process It is more stable and controllable, and at the same time achieves the effect of microwave insecticide and sterilization.

In this embodiment of drying the aerosol-generating substrate 30, in the microwave baking step, it can also be carried out by combining vacuum microwave baking and normal pressure microwave baking in the above-mentioned embodiment. The undried aerosol After the substrate 30 is microwave-expanded to remove 10-60% of the water content, it is then baked in a vacuum drying and baking manner.

Please refer to FIG. 24 , which is a schematic structural diagram of a drying device 828 for the aerosol generating substrate 30 ; in another embodiment, the aerosol generating substrate 30 is dried by using the drying device 828 for the aerosol generating substrate 30 .

The aerosol-generating substrate drying device 828 adopts a freeze-drying method. Freeze-drying is a drying technique using the principle of sublimation. It is a process in which the dried material is quickly frozen at a low temperature, and then in a suitable vacuum environment, the frozen water is directly sublimated into water vapor to escape. The product obtained by lyophilization is called a lyophilizate, and the process is called lyophilization. The substance is always at low temperature (frozen state) before drying, and the ice crystals are evenly distributed in the substance, and the sublimation process will not be concentrated due to dehydration, avoiding side effects such as foam and oxidation caused by water vapor. The dry substance is in the porous shape of a dry sponge, and the volume is basically unchanged, which prevents the physical, chemical and biological denaturation of the dry substance to the greatest extent.

The aerosol-generating substrate drying device 828 includes a vacuum drying box 450, a drying area 452 in the vacuum drying box 450, a heat source 454 in the vacuum drying box 450, and a vacuum system 456 for vacuuming the vacuum drying box 450. , a freezing box body 458, a freezing zone 460 in the freezing box body 458, and a refrigeration system 462 for freezing materials in the freezing box body 458.

In this embodiment, the undried aerosol-generating substrate 30 is first put into the freezing zone 460 in the freezing box 458, and the refrigeration system 462 is activated to freeze the undried aerosol-generating substrate 30 to -55°C. -0°C, make the undried aerosol generating substrate 30 fully crystallized and then take it out to obtain the crystallized aerosol generating substrate 30. At this time, the moisture in the crystallized aerosol generating substrate 30 becomes ice crystals and is evenly distributed in the The crystallized aerosol is generated inside the substrate 30, and then put into the drying area 452 in the vacuum drying box 450 for vacuum drying.

The drying temperature of the vacuum drying cabinet 450 is set to 30-80°C, preferably 45-65°C, the degree of vacuum is set to 10-90KPa, preferably 30-60KPa, the time is set to 30-900 minutes, and the starting equipment is set to the crystallized gas. The sol generating substrate 30 is vacuum-dried; the crystallized aerosol generating substrate 30 is always at a low temperature (frozen state) before drying, and at the same time, ice crystals are evenly distributed in the crystallized aerosol generating substrate 30, and the ice crystals are heated and sublimated. The dry sublimation process will not cause condensation due to dehydration, avoiding side effects such as foam and oxidation caused by water vapor. The dried aerosol-generating substrate 30 is in the shape of sponge and porous, and its volume is basically unchanged, so as to prevent the physical, chemical and biological denaturation of the aerosol-generating substrate 30 to the greatest extent. When the moisture content in the aerosol-producing substrate 30 is dried to 5-15% by weight of the aerosol-producing substrate 30, the dried heated and smokeable aerosol-producing substrate 30 is obtained.

Freeze-drying technology is used to dry the aerosol production substrate, and the aerosol production substrate will not shrink or expand. The aerosol produced after heating the material passes through smoothly; at the same time, because it is dried at a low temperature, the aerosol production substrate will not appear in a hardened state and cannot be inserted into the heating component of the heating appliance. The aerosol obtained by the freeze-drying method Production base material, whose hardness is 0.5-2.5kgf, is easy to insert into the heating element of the heating appliance.

During the baking process, the puffing agent in the raw material of the aerosol-generating substrate 30 is heated and decomposed to generate gas, which makes the paste-like aerosol-generating substrate 30 puff up, increasing the volume, making the volume structure soft, and forming a loose tissue with pores and uniform pores. The principle of thermally decomposing the swelling agent of the aerosol-generating substrate 30 to generate gas has been described in the above-mentioned embodiments, and will not be repeated here.

During the baking process, a large amount of water contained in the raw material of the aerosol generating substrate 30 evaporates, so that the density and hardness of the aerosol generating substrate 30 become smaller, which is suitable for inserting and heating by a heating device.

In the embodiment of drying the aerosol-generating substrate 30, microwave drying and freeze drying can also be used. First use the aerosol generating substrate drying device 824 to perform preliminary microwave baking on the undried aerosol generating substrate 30 according to the method in the above-mentioned embodiment, so that the undried aerosol generating substrate 30 is subjected to microwave action. Under puffing, remove 10-60% of the moisture content in the aerosol generating substrate 30 at the same time; take out the semi-dried aerosol generating substrate 30, and then put the semi-dried aerosol generating substrate 30 into the drying device 828 In the freezing area 460 in the middle freezing box 458, start the refrigeration system 462 to freeze the semi-dried aerosol generating substrate 30 to -55°C-0°C, so that the moisture in the semi-dried aerosol generating substrate 30 is completely crystallized Finally, take it out to obtain the crystallized aerosol generating substrate 30, and then put it into the drying zone 452 in the vacuum drying box 450 to dry the crystallized aerosol generating substrate 30 to the moisture content of the aerosol according to the method in the above-mentioned embodiment. 5-15% by weight of the base material 30 is produced, that is, the dried aerosol production base material 30 is obtained.

Combining the microwave baking of the aerosol-generating substrate drying device 824 and the freeze-drying baking of the aerosol-generating substrate drying device 828 can give full play to the advantages of the two baking methods. Microwave baking has high baking efficiency and good microwave puffing effect, and can quickly remove the moisture in the undried aerosol generation substrate 30 to achieve the purpose of puffing. At the same time, the freeze drying method is used to further dry the crystallized aerosol generation Substrate 30, so that the moisture in the crystallized aerosol-generating substrate 30 is always at a low temperature (frozen state) before drying, and at the same time, ice crystals are evenly distributed in the crystallized aerosol-generating substrate 30, and the sublimation process will not occur due to dehydration Concentration phenomenon avoids side effects such as foam and oxidation caused by water vapor. The dried aerosol-generating substrate 30 is in the porous shape of a dry sponge, and its volume is basically unchanged, preventing the physical, chemical and biological denaturation of the aerosol-generating substrate 30 to the greatest extent.

In the drying embodiment of the aerosol generating base material 30, the undried aerosol generating base material 30 can also be put into the drying device 828, and the freezing zone 460 in the freezing box body 458 can generate the undried aerosol. The substrate 30 is frozen to -55°C-0°C, and the moisture in the undried aerosol generating substrate 30 is completely crystallized, then taken out to obtain a fully crystallized aerosol generating substrate 30, and then put into the drying device 824 The crystallized aerosol-generating substrate 30 is microwave-baked according to the method in the above-mentioned embodiment, and a vacuum is used in the microwave-baking process. When the moisture content of the aerosol-generating substrate 30 is dried to 5-15% of the weight of the aerosol-generating substrate 30, the dried aerosol-generating substrate is obtained.

In this drying example, the undried aerosol-generating substrate 30 is frozen before microwave baking, and then baked by vacuum microwave baking. Since the aerosol-generating substrate 30 is always in the Low temperature (frozen state), at the same time, ice crystals are evenly distributed in the substance, and the sublimation process will not cause condensation due to dehydration, avoiding side effects such as foam and oxidation caused by water vapor. At the same time, due to the high efficiency of microwave baking, the moisture in the aerosol-generating substrate 30 can be quickly removed, so as to achieve the effects of accelerating baking and killing insects and bacteria.

In the drying embodiment of the aerosol-generating substrate 30, the undried aerosol-generating substrate 30 can also be put into the drying device 828, and the freezing zone 460 in the freezing box 458 freezes the aerosol-generating substrate 30. To -55°C-0°C, after the aerosol generating substrate 30 is completely crystallized, take it out to obtain the crystallized aerosol generating substrate 30, and then put it into the drying device 824 to generate the crystallized aerosol according to the method in the above embodiment The substrate 30 is preliminarily baked by microwaves, so that the crystallized aerosol-generating substrate 30 expands under the action of microwaves, and at the same time removes 10-60% of the moisture content in the crystallized aerosol-generating substrate 30 to obtain a semi-dried aerosol Generate the substrate 30; then take out the semi-dried aerosol to generate the substrate 30, then put the semi-dried aerosol to generate the substrate 30 into the drying area 452 in the vacuum drying box 450 in the drying device 828 according to the above The method in the embodiment dries the moisture content of the aerosol-generating substrate 30 to 5-15% of the weight of the aerosol-generating substrate 30 to obtain the dried aerosol-generating substrate 30 .

In this drying example, the aerosol generating substrate 30 is frozen before microwave baking, and then baked by vacuum microwave baking to remove a large amount of water from the aerosol generating substrate 30, and then put it into Putting it into a vacuum drying box for drying can greatly shorten the vacuum drying time, and at the same time make the internal loose structure of the aerosol generating substrate 30 more uniform, and at the same time achieve insecticidal and sterilizing effects.

In the above-mentioned embodiments, polar molecules will move violently during the microwave baking process, thereby generating heat instantaneously inside the aerosol-generating substrate, and then generating steam pressure inside the aerosol-generating substrate, making the paste-like gas The sol produces a vapor pressure gradient inside the base material, forcing the paste-like aerosol to expand the base material, and relying on the expansion force of the gas to drive the paste-like aerosol to produce structural denaturation of the polymer material in the base material 30 .

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

There are many ways to dry materials. Traditional heating methods (heat conduction, convection, and radiation) heat and dry materials from the surface of the material from the outside to the inside. This invention provides another method for preparing aerosol-generating substrates. In an embodiment, the preparation method adds metal materials from the raw material formula, and uses high-frequency induction technology to heat the metal material inside the aerosol production substrate during the drying process of the aerosol production substrate, so that the heating of the aerosol production substrate It is heated evenly from the inside, which speeds up the drying process.

In this embodiment, a metal material is added to the raw material of the aerosol-generating substrate 30, so that in the subsequent high-frequency induction drying device, the surface of the metal material is subjected to high-frequency waves to form an induction current of the same frequency, and then heat is generated rapidly, so that the aerosol The base material 30 is internally heated by the metal material, so as to achieve the effect of drying.

In this embodiment, the method for preparing the aerosol-generating substrate includes three steps: preparing the aerosol-generating substrate as a paste-like material, preparing the paste-like material into the shape of the aerosol-generating substrate, and drying the aerosol-generating substrate. Further, in this embodiment, the preparation method of the aerosol-generating product includes the preparation of the paste-like material of the aerosol-generating substrate, the molding process of preparing the paste-like material into the shape of the aerosol-generating substrate, and drying the aerosol-generating product of semi-finished products in three steps.

In the second step, after the preparation of the paste-like material of the aerosol-generating base material 30 is completed, the paste-like material is started to be formed into an aerosol-generating base material 30. The method for forming the aerosol-generating base material 30 provided by the present invention The method for forming the aerosol-generating substrate 30 in the above-mentioned embodiment is the same to obtain the aerosol-generating substrate 30 with the metal material. The molding method is described by citing the drawings of the above-mentioned embodiments.

The aerosol-generating substrate after drying.

Please refer to Fig. 25, Fig. 25 is a schematic structural diagram of an aerosol-generating substrate drying device 830; The aerosol generating substrate 30 having the metallic material is dried.

The aerosol-generating substrate drying device 830 includes an induction oven 468 and a high-frequency power supply 466 . The high-frequency power supply 466 provides high-frequency power supply to the induction oven 468, and the frequency of the power supply is 100-500KHZ; the induction oven 468 is an inductor wound by a hollow copper tube. After the high-frequency power supply is connected, the induction oven 466 generates high-frequency waves, The aerosol with the metal material generates an induced current of the same frequency on the surface of the metal material inside the base material under the action of high-frequency waves, and rapidly generates heat. Because the metal material is evenly distributed inside the material, the material is evenly heated inside to achieve a fast drying effect.

Put the aerosol-generating base material with metal material to be dried into the sensor oven 468, and the temperature of the sensor oven 468 is set to 30-80°C, preferably 45-65°C; the high-frequency power supply 466 outputs to the sensor The power supply power of the device oven 468 is 0.8-4.0KW per kilogram of material, preferably 1.0-2.5KW; the baking time is set to 100-600 minutes, the induction oven 468 is connected to the high-frequency power supply 466, and the power frequency is 100-500KHZ. The induction oven 468 generates high-frequency waves. Under the action of the high-frequency waves, the aerosol with the metal material generates an induced current of the same frequency on the surface of the metal material in the base material, and quickly generates heat.

During the baking process, the metal material in the aerosol-generating base material is subjected to high-frequency waves in the induction oven 468 to generate heat to heat the aerosol-generating base material inside, and the expanding agent in the aerosol-generating base material is heated and decomposed to produce The gas makes the paste-like aerosol produce substrate expansion, increase the volume, make the volume structure soft, and form a porous and uniform loose tissue. The principle of generating gas by thermally decomposing the bulking agent of the aerosol-generating substrate has been described in the above-mentioned embodiments and will not be repeated here.

During the baking process, a large amount of water contained in the raw material of the aerosol-generating substrate evaporates, so that the density and hardness of the aerosol-generating substrate become smaller, which is suitable for insertion into a heating device for heating.

Finally, after the moisture of the aerosol production substrate is dried to 5-15% of the weight of the aerosol production substrate, the dried heated and smokeable aerosol production substrate is obtained.

Further, by using the principle that the boiling point of the liquid decreases under low pressure, the sensor oven 468 of the aerosol-generating substrate drying device 830 can also be vacuumed to accelerate the aerosol-generating substrate 30 with metal materials. drying process.

The interior of the sol production base material is evenly heated, the drying efficiency is fast, the heating effect is better, the material consistency is better, and the porosity distribution is more uniform.

Please refer to FIG. 26 . FIG. 26 is a schematic diagram of the undried aerosol generating substrate 130 being cut into aerosol generating substrate 132 with tubular packaging material after being dried. Aerosol-generating substrate with tubular packaging material 132 has a section of the tubular packaging material that is an empty tube that can be loaded with other components.

Please refer to FIG. 27 . FIG. 27 is a schematic diagram of the undried aerosol generating substrate 134 cut into aerosol generating substrate 136 with tubular packaging material after being dried. Aerosol Generating Substrate 136 with Tubular Packaging Material The tubular packaging material has an empty section within which other components may be loaded.

The dried aerosol generating substrate obtained by the above embodiment has the characteristics of small hardness, porous sponge inside, low moisture content, and columnar integrated substrate, so that the aerosol generating substrate 30, tubular The aerosol generating substrate 132 of the packaging material and the aerosol generating substrate 136 with the tubular packaging material can be inserted into the heating element of the heating appliance, and the heat generated by the heating element heating of the heating appliance is generated in the aerosol generating substrate 30 and the tubular packaging material. The aerosol generating substrate 132, the aerosol generating substrate 136 with tubular packaging material have good heat transfer effect, and the heating is uniform, and the heating device heats the aerosol generating substrate 30, the aerosol generating substrate 132 with tubular packaging material, The aerosol generated by the aerosol-generating substrate 136 with tubular packaging material can pass through the internal porous space smoothly and has suitable suction resistance. The temperature of the aerosol sucked into the mouth is moderate, which is suitable for consumers to inhale.

The aerosol generating substrate 30, the aerosol generating substrate 132 with tubular packaging material, and the aerosol generating substrate 136 with tubular packaging material obtained by the above-mentioned several baking methods have a soft structure and a porous and loose interior. The raw materials contain metal materials, so that the weight of the aerosol-generating substrate is relatively heavy, and the density distribution range of the aerosol-generating substrate is 0.10-0.90 g/cm ³ after removing the metal material components.

The metal material added in the above-mentioned aerosol generating substrate 30, the aerosol generating substrate 132 with tubular packaging material, and the aerosol generating substrate 136 with tubular packaging material can also be a magnetic material, or can be a metal material and a magnetic material. , the molding method of the paste shape, the drying method, the drying principle, the effect and the formed aerosol generating substrate 30, the aerosol generating substrate 132 with tubular packaging material, the aerosol generating substrate with tubular packaging material The structure and suction effect of the base material 136 are the same.

Aerosol-generating products containing metal materials, aerosol-generating products containing magnetic materials, and aerosol-generating products containing metal materials and magnetic materials can generate heat by themselves through the action of changing magnetic fields, so that the aerosol-generating substrate 30 1. The aerosol generating substrate 132 with tubular packaging material and the aerosol generating substrate 136 with tubular packaging material are heated to generate aerosol; the aerosol generating product can also be heated by an electromagnetic heating device for suction without insertion The heating element of the heating appliance is heated, so that there will be no aerosol-generating base material 30 remaining on the heating element when it is pulled out, which is convenient for cleaning the heating appliance; at the same time, when the aerosol-generating product is heated by electromagnetic induction, the electromagnetic The susceptor heats up evenly, so that the aerosol generating substrate 30, the aerosol generating substrate 132 with tubular packaging material, and the aerosol generating substrate 136 with tubular packaging material are evenly heated to achieve a better suction effect.

In addition to the above-mentioned drying methods, other drying machines can also be used for drying aerosol-generating substrates, such as rotary dryers, drum dryers, tunnel microwave dryers, tunnel dryers, net dryers, etc. Belt tunnel furnace, vacuum rake dryer, double-cone vacuum dryer, low-temperature single-cone vacuum dryer, etc., can also make the aerosol substrate 30 expand by adopting appropriate temperature, time, and additional vacuuming. , loose structure and other purposes. There are many kinds of drying methods, and I will not list them one by one here. Only the drying methods that can achieve the desired baking purpose can be used.

The aerosol-generating substrate obtained in the above examples contains crystal blocks and fiber filaments inside, and the fiber filaments are unevenly distributed between the crystal blocks. The crystal blocks include plant raw material powder and aerosol base material forming agent, and are formed during the forming and drying process of the aerosol generating base material. The crystal blocks have irregular shapes and sizes, and the crystal blocks are adhered to each other to form the integral aerosol generating substrate. When the packaging material is also included in the forming process of the aerosol-generating substrate, the crystal blocks in the contact part with the packaging material are still stuck together with the packaging material. There are unevenly arranged and irregularly sized voids between the crystal blocks, and the porosity between the crystal blocks is 45%-70%, thereby forming a loose porous structure. The liquid raw materials in the aerosol-generating substrate, such as aerosol-generating agent, tobacco extract, essence and fragrance, and water, penetrate into the crystal block and the fiber filament. Glycerin is a commonly used aerosol generating agent. When glycerin is used as an aerosol generating agent, glycerin will penetrate into the crystal block and the inside of the fiber filament.

The interior of the aerosol generating substrate contains the crystal block and the fiber filament, and the water content of the crystal block after drying is 3% to 15%. The total weight of the crystal blocks accounts for more than 10% of the total weight of the aerosol generating substrate.

After the aerosol-generating substrate is dried, the water evaporates. During the drying process, the paste in the aerosol-generating substrate expands to obtain an aerosol-generating substrate with a lower density. The density range of the part excluding packaging materials and metal materials is within Between 0.1g/ml and 0.9g/ml.

The dried aerosol-generating base material obtained in the above examples, although the interior of the aerosol-generating base material is loose and porous, and the internal gaps can allow the aerosol generated by heating to pass through, but after all, the gaps are small, and the aerosol-generating base material There is no through hole from one end of the material to the other end. When the aerosol is not heated, the suction resistance of the base material is relatively large. Compared with the traditional heat-not-burn smoke, the suction resistance is relatively large. In addition, for the dried aerosol generating substrate obtained in the above embodiment, the aerosol generating agent in the aerosol generating substrate accounts for 1%-12% by weight of the aerosol generating substrate.

In accordance with the N°81 Conventional Analyzer for E-cigarette Aerosol Generation and Collection-Definition and Standard Conditions recommended by CORESTA (Cooperation Center for Scientific Research Relative to Tobacco), the smoking resistance test was performed with a smoking machine, and the test conditions For: suction ambient temperature: 22℃±2℃, relative humidity 60%±5%, maximum suction rate 18.5ml/s±1ml/s, suction frequency 30s±0.5s, suction volume 55ml±0.3ml, The suction duration is 3s±0.1s, the suction waveform is a square wave, and the pressure drop of the smoking machine is ≤300Pa. When testing the draw resistance of traditional cigarettes and electronic cigarettes according to the above conditions, most of the draw resistance will be lower than 1.0KPa, even lower than 0.8KPa, or lower than 0.5KPa, and the draw resistance above 2.0KPa rarely occurs. When the aerosol-generating base material obtained in the above examples is added with packaging materials and then heated and directly smoked, its suction resistance is generally greater than that of traditional cigarettes and electronic cigarettes, and its suction resistance is greater than 2.0kpa, accounting for more than 50%. The resistance is greater than 1.0kpa and more than 70%, the suction resistance may exceed 2.5KPa, may exceed 3.0KPa, may exceed 4.0KPa, and the suction resistance range is between 1.0KPa-5.0KPa.

When the aerosol-generating substrate is heated and sucked, the first suction resistance is relatively large, which may exceed 1.5KPa, may exceed 2.0KPa, and may exceed 3.0KPa. The suction resistance gradually decreases, and after 3-4 mouthfuls, the suction resistance decreases to about 1.0Kpa, which is more suitable for smokers.

The susceptor assembly 39 includes a susceptor 162 and a base 160 , and the susceptor 162 is mounted on the base 160 .

Of course, in other embodiments, one or more susceptors 162 of the same or different materials can also be arranged in the aerosol generating substrate 30 horizontally or in other directions.

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

Another preferred metal material for susceptor 162 may also be aluminum or aluminum alloy material.

The susceptor 162 material also includes suitable non-magnetic, especially paramagnetic conductive materials, such as aluminum (Al) or aluminum alloy materials. In paramagnetic conducting materials, induction heating occurs only by resistive heating due to eddy currents.

The susceptor 162 material may include a non-conductive ferrimagnetic material, such as a non-conductive ferrimagnetic ceramic. Under these conditions, heat is only generated by hysteresis losses.

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

The susceptor 162 has a Curie temperature of less than 500°C, preferably less than 400°C, preferably about 150-380°C.

Preferred susceptors 162 are strips, rods, pins, cones, granules, rods, hollow tubes, flakes, blades, spirals, spheres, T-shaped, crosses, triangles, ovals, cones , Quadrilateral, pentagonal, hexagonal, polygonal and irregular contours and other shapes. The dimension of the material of the susceptor 162 in the length direction may be 3mm-18mm, and the dimension in the width direction may be 1mm-7mm. When the material of the susceptor 162 is a sheet, the thickness of the susceptor material can be 0.01mm to 3mm; when the material of the susceptor 162 is a rod, the outer diameter can be 1mm-3mm; when the material of the susceptor 162 is In granular form, its outer diameter is 0.01mm-3.0mm. The susceptor material has a surface area of 0.1 mm ² -150 mm ² .

It can be understood that there can be one or more receptors in the aerosol generating substrate 30, and they can be made of the same material or different materials. Multiple receptors can be in contact together, such as pressed together, or one receptor can be covered on the outer layer of another receptor; multiple receptors can also be separated; different receptors can have the same shape, or have different shapes, For example, one susceptor is flake-like, and the other susceptor is granular, or rod-like, or sheets of different sizes and shapes.

The surface of the susceptor 162 can also be coated with a protective material, such as a protective ceramic layer, a protective Teflon coating, a protective glass layer; or an electroplated inert metal protective layer, such as electroplating a nickel layer on the ferrite surface.

When the susceptor 162 is made of multiple different materials, they may have different Curie temperatures. The susceptors with different Curie temperatures can be called heating susceptors and temperature control susceptors respectively. The heating susceptor has a heating Curie temperature for heating the susceptor to a certain temperature, and the temperature control susceptor has a temperature control Curie temperature for controlling the susceptor in a certain temperature range. When the temperature-controlled susceptor is heated to the temperature-controlled Curie temperature, its magnetic properties change, and the susceptor material changes reversibly from the ferromagnetic phase to the paramagnetic phase. During the inductive heating of the aerosol-generating substrate, the phase transition of the temperature-controlled susceptor material can be detected online, thereby automatically stopping the inductive heating. Therefore, even if the heating susceptor heating Curie temperature is higher than the temperature control Curie temperature, since the equipment automatically stops induction heating, the heating susceptor also stops heating, preventing the local overheating and burning of the aerosol-generating substrate. After the induction heating is stopped, when the temperature-controlled susceptor cools down to a temperature below the temperature-controlled Curie temperature, the temperature-controlled susceptor regains its ferromagnetic properties again, the lid phase transition is detected online, and the induction heating is activated again.

Of course, when there is only one kind of susceptor, heating the Curie temperature is temperature-controlled Curie temperature, and the susceptor has both heating function and temperature control function. Of course, the heating sensor and the temperature control sensor are separated, and the temperature difference between the heating Curie temperature and the temperature control Curie temperature is large enough, the heating temperature can be effectively controlled, and the local overheating and scorching of the substrate can be prevented from generating aerosol.

When the susceptor 162 is heated, the resistance of the susceptor will become larger or smaller. When selecting different material susceptors, materials with the same temperature coefficient of resistance can be selected, and materials with different temperature coefficients of resistance can also be selected to achieve a similar effect.

The receptor 162 is arranged near the aerosol-generating substrate, preferably, arranged around the aerosol-generating substrate 30, preferably, arranged inside the aerosol-generating substrate 30, and the receptor has at least A part is in contact with the aerosol-generating substrate, and when the receptor is completely wrapped and in contact with the aerosol-generating substrate, the heat conduction is the best and the heating effect is the best.

In order to make the aerosol produced by the aerosol-generating product taste more pleasant and have less miscellaneous gas during the heating and inhalation process of the heater heating component, the assembled aerosol-generating product can also be alcoholized by high-frequency induction.

The plant raw material of the aerosol generating substrate 30, although the macromolecular structure inside the plant raw material is split into small molecular structures through natural fermentation or fermented enzyme fermentation, it cannot completely decompose the macromolecular structure inside the plant raw material for small molecular structures. In order to further decompose the macromolecular structure inside the plant material, after the assembly of the aerosol-generating product is completed, high-frequency induction alcoholization can be carried out to further split the macromolecular structure inside the aerosol-generating product to achieve the aerosol-generating product The purpose of alcoholization.

The plant raw material of the aerosol-generating substrate 30 is composed of groups with large molecular structure, and the taste of the macromolecular structure itself is relatively strong.

The taste of structure formation.

Please refer to FIG. 59 , which is a schematic structural diagram of a high-frequency induction alcoholization device 840 ; the high-frequency induction alcoholization device 840 includes an inductor 470 and a high-frequency power supply 472 . The inductor 470 is a high-frequency inductor wound by a hollow copper tube, which can generate high-frequency waves when connected to the high-frequency power output by the high-frequency power supply 472;

Put the aerosol-generating product into the sensor 470, the sensor 470 is connected to the high-frequency power output from the high-frequency power supply 472, the sensor 470 generates high-frequency waves, and the induction time is set to 10-180s.

In the drying embodiment of the aerosol-generating substrate 30 of the present invention, there are many advantages in adopting high-frequency wave baking.

First, the heating is rapid and the efficiency is fast. When the aerosol generating base material 30 with metal material is put into the induction oven 468 and the high-frequency power is turned on to start baking, the metal material inside the aerosol generating base material 30 will generate heat immediately under the action of high-frequency waves, and the aerosol generating base material 30 The inside and outside reach the heating temperature instantly.

Second, heat evenly. The metal material is uniformly distributed inside the aerosol generating substrate 30, so that the aerosol generating substrate 30 generates heat energy at the same time, and no external coke and internal growth phenomenon will occur. As the moisture on the surface of the aerosol-generating substrate 30 continues to evaporate, the temperature on the surface of the aerosol-generating substrate 30 will be slightly lower than the temperature of the inner layer, and the temperature gradient formed is from the inside to the outside, which is consistent with the migration direction of the vapor pressure that occurs during the heating process. It is consistent with the direction of heat transfer. According to the theory of material drying, this heating state is extremely conducive to material drying.

Third, the thermal inertia is small, the immediacy of heating is easy to control: the energy output by the high-frequency wave is immediately absorbed and heated by the metal material in the aerosol-generating substrate 30, as long as the high-frequency power supply is controlled, immediate heating or termination can be realized. There is no warm-up process.

Fourth, high-frequency waves have the effect of killing insects and sterilizing bacteria: the aerosol production substrate 30 can remove insect pests in the aerosol production substrate under the action of high-frequency microwaves in the sensor oven 468 of the aerosol production substrate drying device 830. And kill bacteria, play the role of insecticide and sterilization.

An electromagnetic heating appliance is used to heat the aerosol-generating product with an electromagnetic susceptor, and the aerosol-generating product does not need to be inserted into the heating element of the heating appliance for heating, so that there will be no aerosol-generating substrate on the heating element when it is pulled out 30 residue, easy to clean the heating appliances. At the same time, when the electromagnetic induction is used for heating, the electromagnetic susceptor will heat evenly, so that the aerosol generating substrate 30 will be evenly heated, and a better suction effect can be achieved.

To sum up, the aerosol-generating product provided by the present invention is an integrated porous and loose aerosol-generating substrate, in which crystal blocks and fiber filaments coexist in the aerosol-generating substrate, and between the crystal blocks There is a gap between them, which can pass through the aerosol generated by heating. The space between the crystal blocks is unevenly arranged. The temperature is low, and the smoker does not need to cool down when smoking, and it will not cause scalding of the mouth. When the aerosol-generating product is inserted into the heating part of the heating device, the insertion force is small, the insertion has no direction requirements, the heat conduction effect is better, the temperature of the aerosol generated is suitable for the suction of the suction person, and the suction resistance is better, which can achieve good The suction effect is excellent, and it can also adapt to the induction heating device for heating and suction.
