in particular, the invention relates to a preparation method and application of cut stems with high concentration.
Background
The tobacco stem is used as the vein of tobacco, accounts for about 20% of the total weight, and mainly comprises cellulose, pectin and a small amount of tobacco aroma substances. In the traditional tobacco processing technology, tobacco stems are mainly used as fillers or raw materials for producing reconstituted tobacco. The adding proportion of the cut stems and the expanded cut stems in the cigarette formula is 10%, the tobacco shred structure and the combustion state are mainly adjusted, the smoke can be optimized, and the tar content of the cigarettes is reduced. In recent years, with the development of the modern cigarette industry, new types of tobacco, in particular, heat non-combustible tobacco products, have been developed rapidly. In the novel heating non-combustion tobacco products mainly sold, after the tobacco components loaded with a certain content of the atomizing agent are heated to a certain temperature, atomizing distillation components are formed, smoke is simulated, and nicotine satisfaction is brought to consumers.
The tobacco material is used as a carrier, and combustion of substances such as tobacco leaves and the like is not needed, so that the main tobacco raw materials at present mainly comprise different types of reconstituted tobacco leaves, and the substances such as cut stems and the like are less researched. For example, patent CN201811015950.6 discloses a high-tobacco-flavor heating non-combustible tobacco and a preparation method thereof, wherein tobacco components, extracts, essences and the like, an atomizing agent, an adhesive and the like are sprayed on microwave expanded tobacco stems. Patent CN201811267752.9 discloses a non-combustible heating cigarette tobacco and a non-combustible heating cigarette prepared from the same, which are prepared from tobacco and a flavor producing material of coating forming paper, adding tobacco stem shreds, adding tobacco stem particles or a smoke agent. Patent CN201810737478.0 discloses an electric heating non-combustible carrier and a preparation method thereof, which is obtained by processing cut stems and then backfilling with an atomizing agent and a fragrant substance.
Compared with the traditional cigarette cut stem processing and producing process, the method has the advantages that the expanded cut stems are mainly added with the atomizing agent in a later feeding mode.
In the traditional cut stem production process, stem washing, stem storage, stem steaming, stem pressing and cutting, material adding, drying and puffing, and flavor adding are carried out. In order to better utilize the existing cigarette process device and realize better application of the traditional cut stems, the existing process is improved and perfected, and the atomization agent is added in the traditional cut stem production process.
