Description

Technical Field

[0001] The present invention relates to the technical field of heated cigarettes, and in particular to a smoking particle for heated cigarettes and a preparation method thereof. Background Art

[0002] Heat-not-burn cigarettes are a type of cigarette made by heating tobacco materials with electronic heating equipment without burning them. During the smoking process, no open flame is used, and tobacco is heated by a special heating source. When heated, nicotine and other substances in the tobacco evaporate to produce smoke to meet the needs of smokers. When smoking this type of cigarette, consumers can not only feel the aroma of tobacco, but also significantly reduce the harmful substances produced by high-temperature pyrolysis of conventional cigarettes during combustion, thus providing consumers with an effective and healthy way to smoke, which is increasingly favored by consumers.

[0003] At present, the main products of heated cigarette cartridges are reconstituted tobacco leaves and smoking particles. The main components of reconstituted tobacco leaves are tobacco powder, adhesives, humectants (propylene glycol and glycerin), enhancers, water, fiber and blended flavors. The finished reconstituted tobacco leaves generally maintain a high moisture content. During the smoking process, the tobacco segment is heated at high temperature. The first thing released is high-temperature water vapor, as well as a small amount of coated tobacco extracts and other characteristic volatile substances, which causes the smoking temperature to be too high and bland. Most of the existing smoking particles use plant-based carriers, which are compounded with tobacco powder, flavors, etc. outside the carrier. However, the plant-based carriers not only have low thermal conductivity, but are also prone to disintegration during the heating process, affecting the smoking taste. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to disclose a smoking particle for heated cigarettes and a preparation method thereof, which uses natural inorganic mineral particles as the core, has good thermal conductivity and is not easy to disintegrate. The loaded smoke-generating agent and functional fragrance are heated evenly, which can greatly improve the smoking taste of the heated cigarettes. The preparation method is simple, which is conducive to cost control and is conducive to industrial promotion and use.

[0005] Specifically, the smoking particles for heated cigarettes of the present invention have a core-shell structure with 30-50 mesh natural inorganic mineral particles as the core and a functional layer compounded outside the core.

[0006] Furthermore, the raw materials of the functional layer include: adhesive, smoke generating agent, functional fragrance and auxiliary materials.

[0007] Furthermore, the auxiliary material is one or more of 80-120 mesh natural inorganic mineral particles, tobacco powder, and natural plant powder.

[0008] Furthermore, the functional aroma materials include tobacco extracts, natural plant extracts and related synthetic flavors, etc. The style characteristics of the functional aroma materials include flue-cured tobacco aroma, air-dried tobacco aroma, fresh fragrance, fruity aroma, spicy aroma, woody aroma, green aroma, floral aroma, herbal aroma, bean aroma, cocoa aroma, milk aroma, paste aroma, baked aroma, sweet aroma, etc. as well as other configurable style characteristics.

[0009] Furthermore, the natural inorganic mineral particles are silica-containing mineral particles.

[0010] Furthermore, the natural inorganic mineral particles are any one of river sand, sea sand and mountain sand.

[0018] S6: Add 1-2 times the mass of 30-50 mesh natural inorganic mineral particles, roll into particles, and bake at 90-105°C for 10-20 minutes;

[0019] S7: Screen the dried particles, select particles with a particle size of 20-30 mesh, and obtain suction particles.

[0020] Furthermore, in the step S3, the mass of the added binder is 1%-6% of the mass of the 30-50 mesh natural inorganic mineral particles, and the mass of the smoke generating agent is 1%-15% of the mass of the 30-50 mesh natural inorganic mineral particles.

[0021] Furthermore, in the step S4, the mass of the added functional fragrance is 2.0%-15% of the mass of the 30-50 mesh natural inorganic mineral particles.

[0022] Furthermore, in the step S5, the mass of the auxiliary material added is 5.0%-20% of the mass of the 30-50 mesh natural inorganic mineral particles.

[0028] 2. The smoking particles for heated cigarettes of the present invention are stable in nature and are not prone to disintegration during the smoking and heating process, so they will not bring extra flavor to the smoke and will not affect the taste of the smoke.

[0029] 3. The smoking particles for heated cigarettes of the present invention use natural inorganic mineral particles, which have a heavy specific gravity, are easier to granulate, have a wide source, and a simple preparation process, which is conducive to cost control and is suitable for industrial promotion and use.
