Background
HNB (non-burning by heating) cigarettes are used as a new type of tobacco products, and the development is rapid in recent years, and represents a development trend of future cigarette products. As a brand new cigarette, the heating mode in the smoking process is greatly different from that of the traditional cigarette, the characteristic requirements on the material in the smoking section of the cigarette are completely different, the material in the smoking section is not combusted by heating, a large proportion of atomizing agent (the main component is glycerol) needs to be added into the material, the application proportion reaches more than 20 percent, and smoke is generated in the heating process.
Glycerol is an oily substance and is difficult to absorb by traditional cut tobacco, so the main means adopted at present is to crush tobacco leaves, tobacco stems and other substances into particles with the particle size of about 50 microns, and increase the absorption area of tobacco materials so as to achieve the purpose of increasing the absorption amount of an atomizing agent, for example, a preparation method of a novel special sheet for tobacco products disclosed by a patent document with the publication number of CN108208917A comprises the following steps: 1) crushing tobacco leaves into tobacco powder; 2) fully mixing the tobacco powder and water in a homogenizing reaction kettle; 3) weighing the additional fibers, pulping by using a disc mill, dispersing by using a homogenizing pump, adding into a homogenizing reaction kettle, and uniformly mixing with the materials in the step 2); 4) weighing an atomizing agent, adding the atomizing agent into a homogenizing reaction kettle, and uniformly mixing the atomizing agent with the materials in the step 3); 5) weighing the adhesive, and preparing into a 2% solution: 6) adding the solution prepared in the step 5) into a homogenizing reaction kettle, and uniformly mixing the solution with the material in the step 4); 7) dehydrating the mixed material in the step 6) by adopting vacuum drying equipment; 8) forming the dehydrated material in the step 7) by using a roller press, drying and shredding to prepare the tobacco product which is not combustible by heating.
In the method, tobacco leaves, tobacco stems and other raw materials are ground, mixed, extracted and the like, and are finally shredded by utilizing a rolling method, a wet method sheet or a dry method sheet processing technology and adding an atomizing agent. The thin slice threads suitable for HNB cigarettes are manufactured and rolled up, the changed thin slice threads are relatively stiff and have poor curling performance, the appearance and the physical properties of the thin slice threads are greatly different from those of the traditional natural cut tobacco, and meanwhile, due to the use of a large proportion of adhesive and other additional additives, a large amount of non-tobacco smell is generated in the heating process of the rolled cigarettes, so that the smoking quality of a cigarette factory is influenced.

Meanwhile, the obtained cut tobacco is made into a cigarette product which is not burned by heating, and the cigarette product is subjected to smoking evaluation, and the evaluation result is shown in the following table 2.
Table 1.
As can be seen from Table 1, the process of the present application can effectively improve the absorption rate of the cut tobacco to the atomizing agent.
Table 2.
As can be seen from table 2, when the cut tobacco obtained by the process of the present application is used in a non-combustible heated smoking article, a large amount of non-tobacco off-flavor is not generated during the heating process, and the sensory quality of the core of the cigarette can be improved.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
