Problems solved by technology

The traditional loose moisture regain method is mainly one-stage loose moisture regain, and its disadvantages are mainly as follows: ① Due to the large difference in physical and chemical properties of incoming materials, the moisture content and temperature of the traditional loose moisture regain export materials fluctuate greatly; ② After loose moisture regain, Tobacco leaves are in contact with the air, and the temperature difference is very large, resulting in an increase in shrinkage rate, which is not conducive to the processing of subsequent processes

Abstract

The invention discloses a tobacco leaf level type loosening and moisture regaining method. According to incoming material characteristics, level type loosening and moisture regaining is carried out on tobacco leaves by adopting a high-intensity low-intensity matching mode; a first level of loosening and moisture regaining aims to made the sliced tobacco leaves to be loosened and remove partial impurity odor, then the loosened tobacco leaves enter a second level loosening and moisture regaining procedure in constant flow, and through the processing of the second level loosening and moisture regaining procedure, the tobacco leaves are made to be reduced in shrinking rate and evener in moisture content; the tobacco leaves after the loosening and moisture regaining enter a storage cabinet for temporary storage, the temperature and the moisture content of the tobacco leaves are made to reach specified technical requirements, and conditions are provided for subsequent processing of the tobacco leaves. The application of the tobacco leaf level type loosening and moisture regaining method enables the loosening rate of the tobacco leaves, the stretching rate of the tobacco leaves, the evenness of the tobacco leaves and aesthetic quality of the tobacco leaves to be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing, and in particular relates to a method for loosening and regaining moisture in stages of tobacco leaves. Background technique [0002] Tobacco leaf loosening and regaining moisture is one of the important processes in the production process of cigarette shreds. Its technological task is to loosen the unpacked and sliced ​​tobacco leaves, increase the moisture content and temperature of the tobacco leaves, increase the processing resistance of the tobacco leaves, and improve the sensory quality. The traditional loose moisture regain method is mainly one-stage loose moisture regain, and its disadvantages are mainly as follows: ① Due to the large difference in physical and chemical properties of incoming materials, the moisture content and temperature of the traditional loose moisture regain export materials fluctuate greatly; ② After loose moisture regain, Tobacco leaves are in contact ...
