Method of raising the homogeneity of stalk shreds

Abstract

The process of raising the homogeneity of stalk shreds includes the following steps: cutting tobacco stalk into shreds, puffing and drying to form puffed stalk shreds, wind selecting to depurate puffed stalk shreds, and sieving puffed stalk shreds in a vibrating sieve with mesh size of 3.35-4.75 mm to separate puffed stalk shreds into two parts including the part in the required size to be fed to the next working procedure and the part with overlong size to be returned to the cutting step.

Description

technical field [0001] The invention relates to a technical method for tobacco processing, in particular to a method for improving the uniformity of shredded stems. Background technique [0002] With the development of tobacco cut stem expansion technology, the expansion effect of dried cut stems has been significantly improved. The preparation method comprises the following steps: a. cutting tobacco stems into shreds; b. processing the cut cut stems through expansion and drying processes to form expanded cut stems; c. sending the expanded cut stems into wind The impurity removal process is selected for impurity removal and purification, and then it is directly blended into shredded leaves and used as a raw material for cigarettes. Under the premise of complying with the cigarette process specification on the physical quality index of cut stems (broken shred rate ≤ 3.0%, filling value ≥ 6.5cm 3 / g), due to the remarkable expansion effect of cut stems, the current processin...

AI Technical Summary

Problems solved by technology

Under the premise of complying with the cigarette process specification on the physical quality index of cut stems (broken shred rate ≤ 3.0%, filling value ≥ 6.5cm 3 / g), due to the remarkable expansion effect of cut stems, the current processing results often cause the proportion of cut stem filaments in cut stems to be too large, and the proportion of filaments above 4.75mm can reach more than 25%, making leaves and cut stems When blending with flake silk, the uniformity of the blending is out of balance, which directly affects the uniformity of cigarette components and the fluctuation of suction resistance after rolling, and the internal quality and the stability of smoke quality are also affected to a certain extent.
