Description

Technical Field

[0001] This invention relates to the field of heated cigarette products technology, and more specifically, to a solid composite aerosol product and its preparation method. Background Technology

[0002] With increasing global concern about smoking and health issues, heated cigarettes have emerged as a potential low-harm smoking alternative. In the development of heated cigarettes, aerosol products made from reconstituted tobacco leaves, shredded tobacco, stems, granules, and paper materials have appeared. Currently, the mainstream aerosol product forms are reconstituted tobacco leaves (tobacco-based) or granules (non-tobacco-based). Solid aerosol products (SAP products), which are non-tobacco leaf and non-granule types, have become an important research direction in this field due to their inherent advantages.

[0003] Among existing heated cigarette products, compared with reconstituted tobacco leaf or granular aerosol products, common solid aerosol products (SAP products) often have problems such as insufficient smoke generation in the smoke generation stage, low smoke generation efficiency per unit time, softness and stickiness, and susceptibility to moisture. This results in poor subsequent processing performance, affecting product quality and performance.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a solid composite aerosol product and its preparation method to solve the above-mentioned technical problems.

[0006] This invention is implemented as follows:

[0007] In a first aspect, embodiments of the present invention provide a solid composite aerosol product, the solid composite aerosol product including a smoke-generating section and a filtering section; the smoke-generating section includes a functional smoke-generating section and a solid core, wherein the functional smoke-generating section is used to provide aerosols and the solid core is used to provide tobacco aroma components;

[0008] The solid core has a through hole in its axial direction; the smoke-generating section and the filter section are arranged in the axial direction, and one end of the functional smoke-generating section is connected to one end of the solid core, while the end of the solid core away from the functional smoke-generating section is connected to the filter section.

[0009] Secondly, embodiments of the present invention provide a method for preparing the aforementioned solid composite aerosol product, the method comprising:

[0010] The prepared smoke-generating section, solid core, and filter section are connected in sequence.

[0011] The present invention has the following beneficial effects:

[0012] The solid-state combined aerosol product provided in this invention significantly improves the smoke generation efficiency, smoke output, and subsequent processing performance through innovative structural design and formulation optimization. The formulation of the solid core in the product has been innovatively modified to focus on supplying tobacco aroma components, while the function of improving smoke generation efficiency and output is primarily delegated to the smoke generation section. Through this division of labor, the functional smoke generation section plays a "supplementary role," working in conjunction with the solid core to effectively improve the overall smoke generation effect of the product. Simultaneously, the product's processing performance is improved, continuous production efficiency is greatly enhanced, and storage time is increased from 3 months to over 1 year. The improved aerosol product is compatible with various external heating devices, such as ring heating, air heating, and ring + air. The preparation method of the solid-state combined aerosol product is simple and can be mass-produced. Attached Figure Description

[0013] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of the present invention and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0015] Figure 2 This is a schematic diagram of the radial cross-section of a solid core. Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Where specific conditions are not specified in the embodiments, conventional conditions or conditions recommended by the manufacturer shall apply. Reagents or instruments whose manufacturers are not specified are all conventional products that can be purchased commercially.

[0017] Currently, the mainstream forms of aerosol products are reconstituted tobacco products (for tobacco) or granular products (for non-tobacco products). Solid aerosol products (SAP products) that are neither tobacco leaves nor granular materials have become an important research direction in this field due to their inherent advantages. Compared with existing reconstituted tobacco and granular products, SAP products have the following advantages:

[0018] 1. Better flavor fidelity: These new products can better preserve the natural aroma components in tobacco, reduce the loss of aroma during processing, and provide a more authentic taste closer to traditional cigarettes.

[0019] 2. Reduced raw material loss: Primarily using a one-piece molding process, SAP products eliminate the need for complex tobacco reprocessing compared to reconstituted tobacco products, reducing energy consumption and costs during production. Unlike pellet products, which may experience raw material loss due to pellet breakage and scattering during filling and use, SAP products can utilize tobacco materials more effectively.

[0020] 3. Lower draw resistance fluctuations: Its uniform structure helps reduce draw resistance fluctuations during smoking, making it smoother for consumers to inhale.

[0021] However, SAP products suffer from problems such as insufficient smoke generation, low smoke generation efficiency per unit time, softness and stickiness, and susceptibility to moisture in the smoke-generating section. These issues lead to poor subsequent processing performance, affecting product quality and performance. To overcome these shortcomings of existing solid aerosol products, this invention is proposed.

[0022] In a first aspect, embodiments of the present invention provide a solid composite aerosol product, the solid composite aerosol product including a smoke-generating section and a filtering section; the smoke-generating section includes a functional smoke-generating section and a solid core, wherein the functional smoke-generating section is used to provide aerosols and the solid core is used to provide tobacco aroma components;

[0023] The solid core has a through hole in its axial direction; the smoke-generating section and the filter section are arranged in the axial direction, and one end of the functional smoke-generating section is connected to one end of the solid core, while the end of the solid core away from the functional smoke-generating section is connected to the filter section.

[0024] It should be noted that the order of the smoke-generating section and the filter section in aerosol products can be adjusted. In this invention, the position of the functional smoke-generating section is set as the edge section of the solid composite aerosol product rather than the middle section. That is, one end of the solid core is connected to the filter section, and the other end is connected to the functional smoke-generating section, with the solid core in the middle position. This design takes into account the possibility that the solid core may shrink and fall off after being inhaled, so the solid core is placed in the middle. In addition, since the solid core itself is mostly brownish-yellow or brownish-black and will turn black after being inhaled, if it is exposed on the end face, it will affect the aesthetics and the consumer experience.

[0025] In other embodiments of the present invention, one end of the solid core is connected to the functional smoke-generating section, and the other end of the functional smoke-generating section is connected to the filter section. That is, the design of the solid core being located at the edge is also possible, but further protection or aesthetic optimization of the periphery of the solid core is required.

[0026] In the embodiments of the present invention, through holes are provided in the axial direction of the solid core to reduce suction resistance; if there are no holes, the suction resistance will increase, hindering the release of aerosols from the functional smoke-generating section and the solid core section, affecting the vaping experience and causing problems such as difficult vaping and low smoke volume.

[0027] In an optional embodiment of the present invention, the raw materials for preparing the functional smoke-generating section, by dry matter mass percentage, include: 8%-40% of a first smoke-forming agent, 0.5%-3.0% of a swelling agent, 22%-45% of porous fiber, 5%-31% of natural plant fiber, 0.5%-6.5% of a binder, and 0%-24% of fragrance and flavoring.

[0028] It should be noted that the functional smoke-generating section is composed of specific smoke-generating materials, and its main function is to improve smoke generation efficiency and smoke volume. The surface and core of the prepared functional smoke-generating section have a porous structure, which has good aerosol generation ability and good sustainability.

[0029] In an optional embodiment of the present invention, the first smoke-forming agent comprises a polyol and its derivatives; preferably glycerol and propylene glycol, wherein the mass ratio of glycerol to propylene glycol is (70-97):(3-30).

[0030] It should be noted that the primary function of the first smoke-forming agent is to generate aerosols and form smoke when heated, providing users with a visual and sensory experience similar to smoking.

[0031] In optional embodiments of the present invention, the bulking agent includes at least one of povidone, polyvinylpyrrolidone, potassium aluminum sulfate, potassium bitartrate, sodium diacetate, sodium bicarbonate, potassium bicarbonate and calcium hydrogen phosphate; preferably povidone, sodium bicarbonate and calcium hydrogen phosphate, wherein the mass ratio of povidone, sodium bicarbonate and calcium hydrogen phosphate is (32-42):(29-39):(19-39).

[0032] It should be noted that the expanding agent helps increase the bulkiness and porosity of the smoke-generating material, reduces adhesion, improves air permeability, and helps form a porous structure, thereby improving the generation and persistence of aerosols and increasing the amount of smoke generated.

[0033] In an optional embodiment of the present invention, the porous fiber includes at least one of cellulose acetate fiber, polycaprolactone fiber, phosphorylated cellulose fiber, chitin fiber, kapok fiber and microcrystalline cellulose; preferably chitin fiber and kapok fiber, wherein the mass ratio of chitin fiber to kapok fiber is (25-53):(47-75).

[0034] It should be noted that the porous nature of porous fibers improves the air permeability of the material, helps to form a porous structure, facilitates the adsorption and storage of smoke-forming agents, promotes the uniform generation of smoke, and increases the smoke generation rate.

[0035] In optional embodiments of the present invention, the natural plant fiber includes at least one of hemp fiber, bamboo fiber, broadleaf wood fiber, coniferous wood fiber and sorghum fiber; preferably hemp fiber, broadleaf wood fiber and bamboo fiber, wherein the mass ratio of hemp fiber, broadleaf wood fiber and bamboo fiber is (25-35):(15-45):(20-60).

[0036] It should be noted that natural plant fibers provide structural support, increasing the stability and mechanical strength of the smoke-generating section and enhancing flexibility. Furthermore, natural plant fibers are breathable; their loose structure allows for airflow within the product, reducing suction resistance.

[0037] In an optional embodiment of the present invention, the binder is selected from any one of cellulose derivatives, pectin and plant polysaccharides.

[0038] It should be noted that the main role of the binder is to assist in molding and maintain structural stability. In the preparation process of functional smoke-generating sections, the binder helps to shape the mixture into the required form, improving production efficiency and product quality consistency.

[0039] In an optional embodiment of the present invention, the fragrance is selected from any one of natural plant extracts and synthetic fragrances.

[0040] It should be noted that flavorings and fragrances can be used to impart specific taste and aroma characteristics to the smoke, such as mint, fruit, or tobacco flavors, depending on different needs and product positioning. During the preparation of functional smoke-generating sections, reasonable adjustments can be made according to actual requirements.

[0041] As mentioned above, the functional smoke-generating section utilizes expanding agents and porous fibers, along with natural plant fibers such as hemp or bamboo. This composition creates a highly absorbent material. The fibers intertwine to form a framework under the action of the adhesive, while the expanding agent creates numerous pores on the surface. The use of natural plant fibers increases the contact area with air, enhancing the permeability of the functional smoke-generating section. This facilitates the smooth flow of air from the bottom or periphery of the aerosol product during inhalation. The adsorbed smoke-forming agents and aroma components form an aerosol, which, along with the air, enters the solid core. After mixing evenly with the aerosol generated by the solid core, it is released through the filtration section.

[0042] In an optional embodiment of the present invention, the raw materials for preparing the solid core, by dry matter mass percentage, include: 50%-80% tobacco powder raw materials, 3%-12% secondary smoke forming agent, 10%-20% powdered fiber, 0.5%-5% binder and 0%-25% flavoring and fragrance.

[0043] It should be noted that the main function of the solid core is to supply the aroma components of tobacco. In conjunction with the functional smoke-generating section, it plays a "supplementary role" and can effectively improve the smoke-generating effect of the entire product. At the same time, the processing performance of the product is improved, and the efficiency of continuous production is greatly enhanced.

[0044] In an optional embodiment of the present invention, the tobacco powder raw material is selected from any one of tobacco flakes, tobacco fragments, tobacco dust and tobacco sticks; the mesh size of the tobacco powder is 50-150 mesh; preferably 80-120 mesh.

[0045] It should be noted that tobacco powder provides the aroma components and nicotine of tobacco, satisfying smokers' pursuit of tobacco taste and physiological needs. Tobacco powder within this particle size range can be better mixed with powdered fibers and other components, providing sufficient specific surface area to maximize the adsorption of flavorings and fragrances, preventing the loss of flavorings and fragrances from penetrating from the solid core, ensuring the aroma quantity of the solid core, and maintaining its aroma and taste stability.

[0046] In an optional embodiment of the present invention, the second smoke-forming agent comprises a polyol and its derivatives; preferably glycerol and propylene glycol, wherein the mass ratio of glycerol to propylene glycol is (68-98):(2-32).

[0047] It should be noted that the second smoke-forming agent generates smoke when heated, simulating the smoke effect of traditional cigarettes and enhancing the smoking experience. Traditional products typically use 15%-25% smoke-forming agent, while the amount of the second smoke-forming agent in this invention is reduced to 3%-12%. This satisfies processability requirements while solving the problems of softness, stickiness, and easy moisture absorption, extending the product's shelf life from 3 months to over 1 year.

[0048] In an optional embodiment of the present invention, the powdered fiber is selected from any one of microcrystalline cellulose, chicory powder, resistant dextrin, and cellulose acetate butyrate.

[0049] It should be noted that the powdered fibers are used to provide structural support, increase the stability and mechanical strength of the solid core, enhance flexibility, and prevent cracking.

[0050] The type of binder used in the preparation of the solid core is the same as that used in the functional smoke-generating section. The role of the binder here is to tightly bind the tobacco powder, smoke-forming agents, flavorings, and other components, ensuring the structural stability of the solid core. This helps the solid core maintain its integrity during production, storage, transportation, and use, preventing it from easily scattering or breaking.

[0051] The types of flavorings and fragrances used in the preparation of solid tobacco cores are the same as those used in functional tobacco-generating sections. The main function of these flavorings and fragrances is to add a rich variety of aromas to the solid tobacco core, improve and modify its original flavor, and satisfy the taste preferences of different consumers. This creates unique aroma characteristics and enhances the pleasure of smoking. During the preparation of solid tobacco cores, adjustments can be made according to actual needs.

[0052] It should be noted that the solid core in this invention is a solid core with an axial through hole. This structure facilitates the transfer of heat from the heating source into the interior of the solid core, enabling uniform heating of the solid core from the inside out, and significantly improving its heating efficiency.

[0053] Specifically, the structure of the solid-state chip is shown below. Figure 2 ,from Figure 2 It is understood that the solid core of the present invention can be designed as a concentric cylindrical structure with an axial single through-hole structure, or as a structure with a grooved axial central single through-hole, depending on actual needs. In other embodiments of the present invention, a series of small through-hole structures can be uniformly designed around the axial center, and their shapes can be rhomboid, circular, triangular, fan-shaped, etc., with no through-hole in the center. The structure of the single through-hole can be adjusted according to the shape of the actual heating element, and can be designed as circular, square, or other shapes.

[0054] In an optional embodiment of the present invention, the length of the functional smoke-generating section is 3mm-15mm; the length of the solid core is 3mm-22mm; the circumference of the functional smoke-generating section and the solid core is 16mm-28mm; and the radial cross-sectional area of ​​the axial through hole of the solid core is 15%-65% of the radial cross-sectional area of ​​the solid cylinder formed by its circumference and length.

[0055] It should be noted that there are certain requirements for the length of the functional smoke-generating section and the solid core. A functional smoke-generating section length of 3mm-15mm generally ensures sufficient smoke concentration; less than 3mm results in lower concentration, while greater than 15mm leads to excessively high concentration, diluting the tobacco aroma components released by the solid core and affecting the tobacco experience. A solid core section length of 3mm-22mm generally ensures sufficient supply of tobacco aroma components; less than 3mm results in a weaker tobacco experience, while greater than 22mm does not significantly improve the tobacco experience and instead increases production costs. The radial cross-sectional area of ​​the axial through-hole of the solid core should form a solid cylinder with a cross-sectional area of ​​15%-65% of its circumference and length. Less than 15% results in higher draw resistance, increasing the flow resistance of aerosols within the through-hole and lower release efficiency; greater than 65% reduces the unit weight of the solid core, releasing less tobacco aroma components and increasing the difficulty of molding and processing the solid core.

[0056] In an optional embodiment of the present invention, the porosity of the functional smoke-generating section is 45%-80%, the air permeability is 2000mL / min-20000mL / min, and the axial pressure resistance is 0.5Pa / mm-20Pa / mm.

[0057] Furthermore, the porosity of the functional smoke-generating section is 53%-72%, and the air permeability is 6000mL / min-16000mL / min.

[0058] It should be noted that the functional smoke-generating section prepared by this invention has high porosity and good air permeability, which has a positive effect on improving smoke generation and smoke generation efficiency.

[0059] In an optional embodiment of the present invention, the density of the functional smoke-generating segment is 0.2 g / cm³. 3 -1.5g / cm 3 The solid core density is 0.4 g / cm³. 3 -1.3g / cm 3 .

[0060] It should be noted that functional smoke-generating sections with a density within an appropriate range readily release aerosols at a relatively fast rate, facilitating the output of tobacco aroma components from the solid core. If this range is exceeded, the aerosol release rate of the functional smoke-generating section is too slow to meet the required smoke volume, and the tobacco aroma components from the solid core are difficult to output, failing to satisfy the desired tobacco smoking experience.

[0061] In an optional embodiment of the present invention, the porosity of the solid core is 0%-20%, the air permeability is 0mL / min-100mL / min, and the axial voltage resistance is 0.1Pa / mm-5Pa / mm.

[0062] Secondly, embodiments of the present invention provide a method for preparing the aforementioned solid composite aerosol product, the method comprising:

[0063] The prepared functional smoke-generating section, solid core, and filter section are connected in sequence.

[0064] Specifically, the preparation method of solid-state combined aerosol products is as follows:

[0065] Two materials, a functional smoke-generating section and a solid core, were prepared according to the raw material ratio. The prepared functional smoke-generating section, solid core, and filter section were then assembled and connected in a predetermined order. See the attached diagram for the specific structure. Figure 1 .

[0066] It should be noted that, compared with existing technologies, this invention effectively solves the problems of low smoke generation efficiency, low smoke volume, susceptibility to moisture, and poor subsequent processing performance of traditional solid aerosol products by setting up a functional smoke generation section and optimizing the solid core formulation. It not only improves smoke generation efficiency and volume but also enhances the stability and reliability of the product during subsequent processing, providing an innovative solution for the aerosol product field with significant practical value. Furthermore, compared with traditional single-solid-core aerosol products, the solid-state composite aerosol product of this invention reduces the smoke generation start-up time by 15% and increases the smoke volume by more than 30% within the same working time. This improvement has been verified through rigorous experimental testing.

[0067] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0068] Example 1

[0069] This embodiment provides a solid composite aerosol product, the preparation method of which includes the following:

[0070] (1) Preparation of functional smoke-generating segment

[0071] The raw materials for the functional smoke-generating section, weighed by dry matter mass percentage, are as follows: 24% smoke-forming agent (20.04% glycerol + 3.96% propylene glycol), 1.75% swelling agent (0.65% povidone + 0.6% sodium bicarbonate + 0.5% dicalcium phosphate), 33.5% porous fiber (13% chitin fiber + 20.5% kapok fiber), 18% natural plant fiber (5.4% hemp fiber + 5.4% broadleaf wood fiber + 7.2% bamboo fiber), 3.5% binder (carboxymethyl cellulose), and 19.25% fragrance and flavor.

[0072] The above raw materials are thoroughly mixed and water is added to form a slurry with a solid content of 20%. The slurry is then subjected to a flexible homogenization process for 2 minutes and spread evenly on a steel strip coated with a release agent. The slurry is then dried at a temperature of 90°C for 15 minutes to obtain an aerosol-generating matrix.

[0073] The aerosol-generating matrix was stripped and dried at 75°C until the moisture content was (8±2)% and the quantification was 60 g / m³. 2 The thickness is 0.20mm;

[0074] The aerosol generating matrix is ​​processed by slicing or embossing, wrapped in forming paper to form a base rod sample, and then cut to make a functional smoke-generating section with a porous structure.

[0075] (2) Fabrication of a solid core with an axial through hole

[0076] Weigh the raw materials for the solid core by dry matter percentage: 65% tobacco powder (Yunnan-produced tobacco flakes, 100 mesh), 7.5% smoke-forming agent (6.23% glycerol + 1.27% propylene glycol), 15% powdered fiber (microcrystalline cellulose), 2.75% binder (carboxymethyl cellulose), and 9.75% flavoring and fragrance.

[0077] The above raw materials are thoroughly mixed and water is added to form a solid core with a solid content of 80%.

[0078] A solid core semi-finished product with a single through hole in the axial center is prepared by extrusion molding using a mold. The hole diameter is 4 mm and the outer circumference is 21.5 mm.

[0079] The product is dried at 75°C until the moisture content is (6±2)%, resulting in a solid core with axial through holes. Figure 2 As shown.

[0143] Under the same environmental conditions (temperature 25℃, humidity (35±5)%RH), a ring-type heating device was used for heating. The smoke concentration was detected by a heating non-combustible comprehensive tester. The time from the start of the heating device to the stable smoke generation was recorded as a comparison of smoke generation efficiency. The average value of the 3rd to 10th inlets was taken as a comparison of the amount of smoke generated within a fixed time. The results are shown in Table 1.

[0144] Table 1. Data on smoke concentration and smoke generation efficiency of aerosol products.

[0145]

[0146] As shown in Table 1, the solid composite aerosol product of the present invention has significant advantages in both stable smoke generation start-up time and smoke generation volume. Examples 1, 2, and 3 demonstrate that the higher the amount of the expanding agent in the functional smoke-generating section within a defined range, the faster the stable smoke generation start-up time and the higher the smoke concentration. Examples 1, 4, and 5 demonstrate that the higher the amount of porous fiber in the functional smoke-generating section within a defined range, the faster the stable smoke generation start-up time and the higher the smoke concentration. Examples 1, 6, and 7 demonstrate that the amount of tobacco powder raw material in the solid core within a defined range has virtually no effect on the stable smoke generation start-up time and smoke concentration. Examples 1, 8, and 9 demonstrate that the amount of smoke-forming agent in the solid core within a defined range has a relatively small effect on the stable smoke generation start-up time and smoke concentration.

[0147] Comparative Example 1 shows that the bulking agent in the functional smoke-generating section has a significant impact on the stable smoke generation start-up time and smoke output. The absence of the bulking agent makes the smoke-generating section more compact, greatly reducing the number of micropores between fibers and obstructing airflow. Compared with Comparative Example 10 (a traditional single solid aerosol product), although the smoke output is slightly increased, the stable smoke generation start-up time is longer. Similarly, Comparative Examples 2-4 show that any component of the bulking agent is indispensable. Although the absence of any one component can accelerate the stable smoke generation start-up time and smoke output, the effect is not as good as the combination of all three components.

[0148] Comparative Example 5 shows that the porous fibers in the functional smoke-generating section also have a significant impact on the stable smoke generation start-up time and smoke output. The absence of porous fibers reduces the air permeability of the fiber skeleton structure in the smoke-generating section, obstructing airflow and affecting smoke output and stable smoke generation start-up time. Analysis of the effect data shows that the impact of porous fibers is slightly less than that of the bulking agent, but it is still equally important. Comparative Examples 6-7 demonstrate that any component in the porous fiber is indispensable; while the absence of any one component can accelerate the stable smoke generation start-up time and smoke output, the effect is not as good as the combination of both components.

[0149] Comparative Example 8 shows that the absence of solid core smoke-forming agent has a certain impact on the overall smoke output, but has little impact on the stable smoke start-up time. This is mainly because the functional smoke-generating section contributes more to the smoke output and improves the smoke generation efficiency, leading to this result.

[0150] Experimental Example 2

[0151] This experiment tested the porosity and air permeability of the functional smoke-generating section in the solid composite aerosol products prepared in Examples 1-5 and Comparative Examples 1-7. The test methods are as follows:

[0152] (1) Porosity test: The gas displacement method was adopted, and the test standard GB / T 10799-2008: Determination of open and closed cell volume percentage of rigid foamed plastics was selected. The instrument model was BSD-TD fully automatic true density analyzer.

[0153] (2) Air permeability test: The constant pressure difference flow measurement method was adopted, and the test standard GB / T22819-2008 "Determination of air permeability of high air permeability paper" was selected. The instrument model was YN-TQD02 electronic air permeability tester.

[0154] The test results are shown in Table 2.

[0155] Table 2 Porosity and air permeability data of functional smoke-generating sections

[0156]

[0157]

[0158] As shown in Table 2, the porosity of the functional smoke-generating sections in Examples 1-5 is all above 50%, and the higher the porosity, the higher the air permeability, which has a positive effect on improving the smoke generation amount and efficiency. Conversely, in the comparative examples, the overall absence or absence of a single component of the expanding agent and porous fiber leads to a decrease in porosity and low air permeability, thus affecting the smoke generation effect of the aerosol product.

[0159] Experimental Example 3

[0160] This experiment evaluated and scored the solid combined aerosol products of Examples 1, 6, 7 and Comparative Example 9. Specifically, seven experts from the evaluation committee were invited to evaluate and score the products using the Hanyan lil ring-shaped heating smoke device. The results are shown in Table 3.

[0161] Table 3 Sensory Quality Evaluation of Solid Combined Aerosol Products

[0162]

[0163] Table 3 shows that tobacco powder raw materials have a significant impact on the strength and aroma of solid-state aerosol products. Strength primarily reflects the physiological satisfaction provided by tobacco raw materials; the higher the amount of tobacco raw materials used, the better the physiological satisfaction. Aroma mainly reflects the aroma components and tobacco experience provided by tobacco; the higher the amount of tobacco raw materials used, the better the tobacco experience and the stronger the aroma. In Comparative Example 9, the lack of tobacco raw materials resulted in a 57.7% decrease in strength and a 39.4% decrease in aroma (based on score comparison). The significant decline in both indicators highlights the importance of tobacco powder raw materials.

[0164] Test Example 4

[0165] This experiment tested the storage time of the solid composite aerosol product prepared in Example 1 and the traditional single solid aerosol product prepared in Comparative Example 10. Specifically, the samples were placed under different temperature and humidity conditions, and the time points at which phenomena such as leakage, spots, and mold appeared on their surfaces were recorded. The results are shown in Table 4.

[0166] Table 4 Comparison of Storage Conditions for Aerosol Products

[0167]

[0168] As can be seen from Table 4, the storage time of the product of Example 1 in the above environment is 3.4 to 4.1 times longer than that of the product of Comparative Example 10. Therefore, the solid composite aerosol product of the present invention has significant advantages in terms of product quality and stability.

[0169] Experimental Example 5

[0170] This experiment tested the hardness of the solid cores with axial through holes prepared in Examples 8 and 9, as well as the traditional single solid aerosol product prepared in Comparative Example 10. The changes in hardness after 30 days under different storage conditions were observed to evaluate the hardness performance and stability of the products. It should be noted that the hardness test in this experiment followed the methods for determining the physical properties of cigarettes. The specific testing equipment was a MU3164 cigarette testing instrument from Shanghai Moujing Industrial Co., Ltd., and the testing standard was YC / T28.6-1996 "Determination of Physical Properties of Cigarettes Part 6: Hardness Spot Indentation Method". The relevant results are shown in Table 5.

[0171] Table 5 Solid Core Hardness Data

[0172]

[0173] As can be seen from Table 5, the content of the raw material smoke-forming agent in the solid core is related to the hardness of the product. In particular, reducing the amount of smoke-forming agent can effectively increase the hardness, and the hardness fluctuation after 30 days is also smaller.

[0174] In summary, the embodiments of the present invention effectively solve the problems of low smoke generation efficiency, low smoke volume, susceptibility to moisture, and poor subsequent processing performance of traditional solid aerosol products by setting up a functional smoke generation section and optimizing the solid core formulation. It not only improves smoke generation efficiency and volume but also enhances the stability and reliability of the product during subsequent processing, providing an innovative solution for the aerosol product field and possessing significant practical value.

[0175] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
