- the present disclosure belongs to a heat-not-burn (HNB) cigarette field, and in particular, to a preparation method of multi-sectional aerosol generating products.
- HNB heat-not-burn
- Aerosol generating matrix of granular heating cigarette is bulk aerosol generating granules
- in the prior art as bulk aerosol generating granules cannot be fixed, they must be filled into the outer tube by filling, besides, both sides of the aerosol generating granule section are sealed by sealing paper and plugging part to fix granules, while in order to gather aerosol and increase the amount of smoke, the downstream of the plugging part is usually a section of cavity (a cavity section) limited by the outer tube, and the downstream of the cavity section is a filtering section.
- the above aerosol generating products are prepared by filling, the production process order is as follows: one end of the tube is sealed, while aerosol generating matrix, the plugging part and the filtering part are sequentially filled from the other end, when filling the filtering part, a cavity distance between the filtering part and the plugging part is reserved, and the outer surface of the plugging part and the filtering part is not glued to the inner wall of the paper tube, after direct filling to a fixed position, they are fixed by friction with the inner wall of the paper tube.

- step 2 determines whether the sealing film is needed according to conditions of the aerosol generating matrix 6.
- drying temperature in step 3 depends on the solvent in the aerosol generating material, i.e., in case the solvent is ethanol, the drying temperature is 50-60°C, with drying time of 0.5-1h; in case the solvent is water, the drying temperature is 60-70°C, with drying time of 1-2h.

Description
- The present disclosure belongs to a heat-not-burn (HNB) cigarette field, and in particular, to a preparation method of multi-sectional aerosol generating products.
- With increasing attention of consumers to health and increasing demand for personalized experiences of cigarette products, the tobacco industry has continuously responded to upgrading of consumers' needs, various smoking products with tar reduction have been developed so as to bring less harm to consumers. Among which, because of different heating methods compared with traditional cigarette products, heating cigarettes can provide a healthier smoking experience while meeting consumers' sensory needs for cigarette products.
- Aerosol generating matrix of granular heating cigarette is bulk aerosol generating granules, in the prior art, as bulk aerosol generating granules cannot be fixed, they must be filled into the outer tube by filling, besides, both sides of the aerosol generating granule section are sealed by sealing paper and plugging part to fix granules, while in order to gather aerosol and increase the amount of smoke, the downstream of the plugging part is usually a section of cavity (a cavity section) limited by the outer tube, and the downstream of the cavity section is a filtering section.
- At present, the above aerosol generating products are prepared by filling, the production process order is as follows: one end of the tube is sealed, while aerosol generating matrix, the plugging part and the filtering part are sequentially filled from the other end, when filling the filtering part, a cavity distance between the filtering part and the plugging part is reserved, and the outer surface of the plugging part and the filtering part is not glued to the inner wall of the paper tube, after direct filling to a fixed position, they are fixed by friction with the inner wall of the paper tube.
- Problem of the above filling method are as follows: 1. The tube is placed vertically during filling, and it is difficult to locate positions of the plugging part and the filtering part on both sides of the cavity, resulting in inconsistent axial lengths of the cavity section of different samples; 2. As the outer surface of the plugging part and filtering part and the inner wall of the paper tube are fixed only by friction, during transportation, the plugging part and filtering part are easy to move toward the cavity section, or the filtering part is partially sucked out of the outer tube during smoking; 3. The filling method is limited in that it can only be filled in batches for individual tubes, resulting in low production efficiency.
- Therefore, efficient production of granular aerosol generating products with a cavity structure, while ensuring stability of the plugging and filtering parts without moving are key problems to be solved in production of granular aerosol generating products.
- The present disclosure is proposed to solve the problems above.
