Production method of reconstituted tobacco special for heating cigarettes

Abstract

The invention provides a production method of reconstituted tobacco special for heating cigarettes, and relates to the technical field of reconstituted cigarettes. The method comprises the following steps of (1) crushing, dividing the tobacco raw materials into two parts, including first tobacco powder and second tobacco powder; (2) grinding, grinding fibers with a grinding machine to prepare fiber slurry; (3) slurrying, uniformly mixing the first tobacco powder, the fiber slurry, water, an adhesive and a fuming agent to prepare a concentrated slurry; (4) coating, uniformly coating the concentrated slurry on a circulating metal belt to form a coating layer; (5) spraying, spraying the second tobacco powder on the coating layer; and (6) carrying out drying for the first time, roller pressing, peeling and drying for the second time to obtain the reconstituted tobacco for the heating cigarettes. The tobacco powder can be additionally added on the premise of ensuring the tensile strength ofthe reconstituted tobacco, so that on one hand, moisture in the concentrated slurry can be effectively absorbed, the drying time is shortened, and the fragrance loss rate is reduced; and on the otherhand, the content of tobacco substances in the reconstituted tobacco can be effectively increased, and the quality of the reconstituted tobacco is improved.

Description

technical field [0001] The invention relates to the technical field of reconstituted tobacco leaves, in particular to a method for producing reconstituted tobacco leaves special for heating cigarettes. Background technique [0002] Heated cigarettes include a tobacco section, a cooling section and a filter section. The core technology is the preparation process of the tobacco core material in the tobacco section and its raw material formula. The reconstituted tobacco leaves for mainstream heated cigarette products are widely used in thick pulp method and papermaking method, and there are also reconstituted tobacco leaves by rolling method and dry method. Reconstituted tobacco leaves for heating cigarettes are used as a smoking medium carrying glycerin, nicotine, and aroma components. It is required that the content of non-tobacco components be low, rich in smoke aroma, and meet the requirements of post-processing. Thick pulp reconstituted tobacco leaves have high water cont...

AI Technical Summary

Problems solved by technology

Thick pulp reconstituted tobacco leaves have high water content in thick pulp, and the drying time is long during the preparation process, resulting in a large loss of aroma components; papermaking reconstituted tobacco leaves and dry reconstituted tobacco leaves have a large content of non-tobacco substances, heavy miscellaneous gases, and lack of tobacco aroma , the consistency of cigarette aroma is poor; the tensile strength of reconstituted tobacco leaves by rolling method is low, easy to break, and the post-processing is difficult

Due to the high water content in the preparation process of thick pulp reconstituted tobacco leaves in the prior art, it often takes a long time to complete the drying, which will cause the volatilization of tobacco flavor components and reduce the retention rate of tobacco flavor components
