Cut rolled stem processing method acquiring high fill value

Abstract

The present invention belongs to a cut rolled stem processing technique, and concretely relates to a cut rolled stem processing method acquiring a high fill value. On the basis of the conventional cut rolled stem production process, humidification and dehydration processes are added in turn between cut rolled stem cutting and material adding processes, the cut rolled stems must be uniformly humidified to enable a moisture content of the cut rolled stems to be higher than 70% and then are dehydrated to control the moisture content to be within 40-50%, material adding treatment is then carried out to enable the moisture content to be controlled between 43-55%, the cut rolled stems are then dried and subsequently processed, and the moisture content of the cut rolled stems is lowered to be 12.0-14.0%, thus to obtain the cut rolled stems of which a fill value is higher than 10.0 cm<3> / g. The method provided by the present invention is simple and easy in operating technique and capable of raising fill performance of the cut rolled stems to a large extent, the fill value is higher than 10.0 cm<3> / g, and a breakage rate of the cut rolled stems can also be reduced.

Description

technical field [0001] The invention belongs to the processing technology for making cut stems, in particular to a method for processing cut stems to obtain high filling value. Background technique [0002] Tobacco stems are the thick and hard veins of tobacco leaves, accounting for about 20% to 30% of the leaf weight. The main component of tobacco stems is lignocellulose, and also contains a small amount of water-soluble aldehydes, ketones and pectin. Therefore, it is still used in the tobacco industry. It needs to be further processed into shredded stems, and then added to shredded tobacco leaves in proportion. See figure 1 , that is, preparation of tobacco stems, washing of stems, storage of stems, steaming of stems, pressing of stems, cutting of stems, feeding, expansion and drying, winnowing, flavoring, and storage of shredded stems. [0003] Cut stems are blended into shredded tobacco as a component of cigarette formula components, which mainly play an important role...

AI Technical Summary

Problems solved by technology

[0013] Above-mentioned prior art various processes all have one thing in common: All of them only use certain methods and technologies to deal with the expansion and drying of tobacco stems or cut stems. The specific surface area of ​​cut stems produced by the above method can be greatly improved, but the filling value can only reach 7.0cm 3 / g or so
