[0021] The present application provides an aerosol-generating article. Refer to Figure 1 , the aerosol-generating article 100 may include a smoking section 10, a cooling section 20, and a filtering section 30. The aerosol-generating article 100 may be columnar, and its cross-section may be circular, oval, or polygonal. The aerosol-generating article 100 has a longitudinal direction. The aerosol-generating article 100 has a proximal lip end and a distal lip end that are oppositely arranged, wherein the proximal lip end is the end close to the user's lips during use, and correspondingly, the distal lip end is the other end far from the user's lips during use. The smoking section 10 is used to generate aerosol when heated. The smoking section 10 is arranged at the distal lip end. The cooling section 20 and the filtering section 30 are arranged at the proximal lip end. The cooling section 20 can cool the aerosol flowing through it so that the temperature of the filtering section 30 will not be too high. The filtering section 30 is used to filter the aerosol to reduce harmful substances in the aerosol. The aerosol-generating article 100 may further include a wrapper 40. The wrapper 40 is in the shape of a hollow cylinder. The wrapper 40 wraps the smoking section 10, the cooling section 20, and the filtering section 30, so that the smoking section 10, the cooling section 20, and the filtering section 30 form an integral body, which is convenient for use. Exemplarily, the wrapper 40 may be a paper tube.
[0022] The fuming part includes plant base material particles and an essence mixture, and the essence mixture is adsorbed on the plant base material particles. The essence mixture can generate an aroma, and the aroma can be in the form of a mist or aerosol. The aroma is mixed into the aerosol, which can enrich or improve the taste of the aerosol. The plant base material particles include plant base material powder, a binder, and a regulator. The regulator is used to adjust the adsorption rate and / or bulk density of the plant base material particles. The adsorption rate refers to the ratio of the liquid that the plant base material particles can adsorb to the self-weight of the plant base material particles. By setting the regulator to adjust the adsorption rate and / or bulk density of the plant base material particles, on the one hand, adjusting the bulk density can control the porosity and contact area between the plant base material particles, so that the essence mixture can be evenly distributed between the plant base material particles, and the consistency of the smoke volume of the aerosol generating article is good, and the aroma release is more uniform; on the other hand, adjusting the adsorption rate enables the plant base material particles to have good adsorption ability. The plant base material particles can adsorb the essence mixture on the plant base material particles, and the essence mixture is stably attached to the plant base material particles, so that the consistency of the smoke volume of the aerosol generating article is good, and the aroma release is more uniform.
[0023] In one embodiment, the particle size of the plant base material particles is 0.4 mm - 3 mm, and the bulk density is 0.9 g / cm 3 - 2.5 g / cm 3 , and the adsorption rate of the plant base material particles is 0.3 - 1.0. Exemplarily, the particle size of the plant base material particles can be 0.4 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm; the bulk density is 0.9 g / cm 3 , 1.4 g / cm 3 , 1.8 g / cm 3 , 2.2 g / cm 3 or 2.5 g / cm 3 ; the adsorption rate is 0.3, 0.5, 0.7, 0.9, or 1.0, which is not specifically limited here. Based on the control of the particle size, bulk density, and adsorption rate of the plant base material particles, the plant base material particles have appropriate particle size, adsorption rate, and bulk density, the essence mixture can be evenly distributed between the plant base material particles, and the essence mixture can be stably attached to the plant base material particles.
[0024] The fuming part can include only one kind of plant base material particles. For example, the plant base material particles are prepared from one kind of plant base material powder such as Zimbabwe tobacco powder, Burley tobacco powder, cigar tobacco powder, or tea stalk powder.
[0025] In one embodiment, the fuming part comprises at least two kinds of plant base material particles. Since different plant base material particles can provide different flavors, the taste of the fuming part is made more abundant. The mass percentage of the plant base material particles of the fuming part that can pass through a 14-mesh sieve and cannot pass through a 24-mesh sieve is greater than or equal to 90%. Based on the control of the particle sizes of various plant base material particles, the discreteness of the particle sizes of the plant base material particles can be reduced, so that various plant base material particles have better consistency, and thus the consistency of the smoke amount of the aerosol-generating article is good and the aroma release is more uniform.
[0026] In one embodiment, the plant base material powder comprises at least one of flue-cured tobacco powder and sun-cured tobacco powder. The flue-cured tobacco powder is made by a hot air baking process. The tobacco leaves are heated (non-open flame) using a heat exchanger in a closed curing barn, and the temperature is controlled within a specific range to gradually dehydrate the tobacco leaves and cause biochemical changes. The sun-cured tobacco powder adopts a natural sun-drying or shade-drying process. The tobacco leaves are hung in a ventilated environment or a shaded shed and slowly dried by natural light or air flow. Due to the high-temperature baking accelerating the caramelization of sugar, the flue-cured tobacco powder has a mellow and slightly sweet flavor and lower irritation. During the natural fermentation process of the sun-cured tobacco powder, more alkaloids and volatile substances are produced, with a strong taste and high strength. The plant base material powder can include either flue-cured tobacco powder or sun-cured tobacco powder, or can include both flue-cured tobacco powder and sun-cured tobacco powder at the same time. By selecting different tobacco powder forming processes, the personalized needs of users can be met.
[0027] In one embodiment, the plant base material powder comprises at least one of Zimbabwe tobacco powder, burley tobacco powder, cigar tobacco powder, and tea stalk powder. The Zimbabwe tobacco powder has a relatively high sugar content, a relatively low content of protein and other nitrogen-containing compounds, a medium nicotine content, a mellow aroma, a soft taste, and low irritation. The burley tobacco powder has a relatively high sugar content, a relatively low content of protein and other nitrogen-containing compounds, a low nicotine content, a unique aroma with a cool and sweet feeling, a relatively soft taste, and low irritation. The cigar tobacco powder has a high nicotine content and a low sugar content, has unique aroma components, a strong tobacco taste, a unique aroma, and strong irritation. The tea stalk powder contains more cellulose, tea polyphenols, and caffeine, has a relatively low sugar and protein content, and a relatively light aroma. The above-mentioned plant base material powders all have unique flavors and can meet the personalized needs of users.
[0028] In one embodiment, the particle size of the plant base material powder is 60 mesh - 400 mesh. Exemplarily, the particle size of the plant base material powder can be 60 mesh, 150 mesh, 250 mesh, 250 mesh, or 400 mesh. Controlling the particle size of the plant base material powder within the above range makes the particle size of the plant base material powder have better consistency, and thus the consistency of the smoke amount of the aerosol-generating article is good and the aroma release is more uniform.
[0029] In one embodiment, the regulator includes at least one of paper cellulose, kudzu root powder, microcrystalline cellulose, tea stem powder, and light calcium carbonate. The main component of paper cellulose is natural cellulose, containing a small amount of hemicellulose, lignin and impurities, and there is a porous network in the structure, which has a strong adsorption capacity. The main component of kudzu root powder is starch, containing a small amount of cellulose, protein and minerals. The starch granule structure is hydrophilic and can adsorb the flavor mixture. The microcrystalline cellulose structure is a porous microcrystalline particle with a high specific surface area and adsorption activity, and has a good adsorption capacity for the flavor mixture. Tea stem powder is processed and crushed by tea stems, containing cellulose, lignin, polyphenols and a small amount of protein. The porous structure (lignin fiber network) enables it to have adsorption capacity. Light calcium carbonate has a fluffy structure and microscopic pores on the surface, which can be used as a carrier to adsorb the flavor mixture. The above-mentioned regulators all have good adsorption capacity and can adjust the adsorption rate of the plant substrate particles; and the above-mentioned regulators all have different densities and can be used to adjust the packing density of the plant substrate particles, thereby controlling the porosity and contact area between the plant substrate particles, so that the flavor mixture can be evenly distributed among the plant substrate particles.
[0030] The binder binds the plant substrate powder into particles with a specific shape (such as columnar, flake-like) and mechanical strength. In one embodiment, the binder includes at least one of sodium carboxymethylcellulose, hydroxypropyl methylcellulose, microcrystalline cellulose, and low-substituted hydroxypropyl cellulose.
[0031] In one embodiment, the flavor mixture includes flavor and smoke-generating agent. The flavor is used to produce aroma, and the flavor may include tobacco extract and tobacco extracted flavor. The smoke-generating agent is a functional component used to simulate the "smoke feeling" of traditional smoking and optimize the smoking experience. The smoke-generating agent may include at least one of propylene glycol and glycerol.
[0032] The present application provides a method for preparing an aerosol-generating product. Figure 2 , the preparation method 300 may include steps S310-S320:
[0033] S310, obtaining plant substrate particles, the plant substrate particles comprising plant substrate powder, a binder, and a regulator, the regulator being used to adjust the adsorption rate and / or bulk density of the plant substrate particles;
[0034] S320, adding a flavor mixture to the plant substrate particles in proportion, so that the flavor mixture is adsorbed on the plant substrate particles to obtain a smoke-generating material, and using the smoke-generating material to prepare a smoke-generating part of an aerosol generating product.
[0035] By setting a regulator to adjust the adsorption rate and / or bulk density of the plant base material particles, on the one hand, adjusting the bulk density can control the void fraction and contact area between the plant base material particles, so that the flavor mixture can be evenly distributed between the plant base material particles, and the consistency of the smoke volume of the aerosol generating article is good, and the aroma release is more uniform; on the other hand, adjusting the adsorption rate enables the plant base material particles to have good adsorption capacity, and the plant base material particles can adsorb the flavor mixture onto the plant base material particles, and the flavor mixture is stably attached to the plant base material particles, thereby making the consistency of the smoke volume of the aerosol generating article good, and the aroma release is more uniform. In addition, the plant base material particles are prepared first, and then the flavor mixture is added to the plant base material particles. The processes of preparing the particles and adding the flavor mixture are separated, so that various plant base material particles with the same level of adsorption rate and bulk density can be prepared in advance. When the smoking section includes a variety of plant base material powders, the characteristics of different particles are already consistent. Only by combining different prefabricated plant base material particles and uniformly adding the flavor mixture can smoking sections with different formulas and styles be obtained, avoiding granulation after separately adding the flavor mixture to each plant base material powder and then mixing, which can reduce the workload of adding the flavor mixture, thereby improving production efficiency.
[0036] The smoking section may include only one type of plant base material particle or may include a variety of plant base material particles. In one embodiment, the step of obtaining the plant base material particles includes: obtaining at least one plant base material particle from at least one prefabricated plant base material particle; wherein, the mass percentage of the at least one prefabricated plant base material particle that can pass through a 14-mesh sieve and cannot pass through a 24-mesh sieve is greater than or equal to 90%, the difference between the bulk density of each prefabricated plant material particle and the average bulk density of the at least one prefabricated plant base material particle is less than or equal to 5% of the average bulk density, and the difference between the adsorption rate of each prefabricated plant material particle and the average adsorption rate of the at least one prefabricated plant base material particle is less than or equal to 5% of the average adsorption rate. The average bulk density refers to the average of the bulk densities of various prefabricated plant base material particles, and the average adsorption rate refers to the average of the adsorption rates of various prefabricated plant base material particles. With such settings, based on the control of the particle size, bulk density, and adsorption rate of a variety of prefabricated plant base material particles, the discreteness of the particle size, bulk density, and adsorption rate of each prefabricated plant base material particle can be reduced, so that a variety of prefabricated plant base material particles have better consistency, thereby making the consistency of the smoke volume of the aerosol generating article good, and the aroma release is more uniform.
[0037] In one embodiment, the step of obtaining the plant base material particles includes: mixing a single-variety plant base material powder with a binder, a regulator, and water, and granulating and drying to obtain a prefabricated plant base material particle; wherein, the particle size of the prefabricated plant base material particle is 0.4 mm - 3 mm, and the bulk density is 0.9 g / cm 3 - 2.5 g / cm 3, the adsorption rate is 0.3-1.0. In this way, a single plant substrate powder is first used to prepare different prefabricated plant substrate particles, and based on the control of the particle size, bulk density and adsorption rate of various prefabricated plant substrate particles, the various prefabricated plant substrate particles have good consistency, so that the smoke volume of the aerosol-generated product is consistent and the aroma release is more uniform.
[0038] In one embodiment, the step of adding the flavor mixture to the plant-based particles includes spraying the flavor mixture onto the plant-based particles using a sprayer; or, the plant-based particles are placed in a rotating container, and the flavor mixture is dripped onto the plant-based particles. Spraying the flavor mixture with a sprayer can make the flavor mixture stably adhere to the plant-based particles, thereby making the amount of smoke in the aerosol-generated product consistent and the aroma release more uniform. In the process of adding the flavor mixture to the plant-based particles, the container containing the plant-based particles is rotated, and the flavor mixture can be evenly distributed between the plant-based particles, which can also make the amount of smoke in the aerosol-generated product consistent and the aroma release more uniform.
[0039] In one embodiment, after the step of adding the flavor mixture to the plant substrate particles, the method further includes filling the plant substrate particles adsorbed with the flavor mixture into a paper tube, which is convenient for users to use.
[0040] The present application is described below through specific examples, in which aerosol generating products are prepared according to the above preparation method. The following examples are only partial examples of the present application and are not intended to limit the present application.
