Recombination processing method for tobacco stem shreds

Abstract

The invention provides a recombination processing method for tobacco stem shreds, for performing recombination processing on chemical components of the stem shreds after the tobacco is cut into shreds. The recombination processing method comprises the following steps: soaking and extracting; separating solid from liquid; flexibly loosening; pneumatically drying; charging into a vertical cylinder and homogenizing; loosening; drying a heat-transferring oil cylinder; and winnowing the stem shreds. The stem shreds processed according to the recombination processing method provided by the invention have higher filling property, fragrance quality and purity; the combustion state of the tobacco is improved; the smoke quality of the tobacco is not influenced and even is promoted; and an effective way for applying the stem shreds to high-class cigarette is developed.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing and manufacturing, and specifically relates to a recombination processing process production method for converting and regulating the chemical components of shredded tobacco stems. Background technique [0002] Tobacco stems account for about 25% of the tobacco leaves. At present, the processing technology and equipment for making tobacco stems into shredded stems are quite mature. The proportion of blended shredded stems in cigarettes varies according to the grade of cigarettes, but The main reason why shredded stems are mainly used in low-grade tobacco is determined by the characteristics of tobacco stems and traditional processing techniques. [0003] Relevant studies at home and abroad have shown that there are essential differences in the physical properties and chemical components of tobacco stems and tobacco leaves. The cellulose, hemicellulose, lignin, and pectin contents of ...

[0006] 2. Add spices and other technical means. Adding feed liquid to the cut stems online can reduce the woody odor and irritation of the cut stems, and improve the taste absorption to a certain extent. At present, it is difficult to achieve large-scale feeding in online feeding, and direct large-scale feeding will lead to variation in the properties of cut stems and reduced combustion performance. Therefore, the effect is limited

This project only dealt with some factors that are not conducive to the smoking of tobacco stems, and did not deal with nitrates and chloride ions that affect combustion and safety, and through the process of washing stems for enzyme treatment, there is a disadvantage of low enzyme efficiency

[0008] 4. Granular stem technology, that is, puffing tobacco stems first, and then feeding them into pellets. In principle, it is still a "expansion + feeding" process technology, and there are wind-powered wire feeding, end falling wires and easy-to-puncture cigarettes. The technical bottleneck of paper, its application is subject to certain restrictions

[0013] First of all, although the cut stems that have been soaked and extracted or extracted have been treated by solid-liquid separation, their water content is still high (about 70%). The water content is very high or even in a saturated state, the ability of the shredded stems to absorb the feed liquid evenly is low, and a large amount of feed liquid will be wasted at the same time

[0014] Secondly, the moisture and viscosity of the cut stems after feeding are very high. If they are dried at this time, the cut stems will stick to various drying equipment on the one hand, and on the other hand, it is difficult for the existing drying equipment to To dry such high-moisture shredded stems in place at one time, two or more drying steps must be carried out, which will seriously lose the aroma components that have been backfilled and added to the stems, and at the same time, the shredded stems will also greatly increase
