Tobacco leaf beating method for reducing stem ratio of secondarily-processed flue-cured tobacco laminas

Abstract

The invention provides a tobacco leaf beating method for reducing stem ratio of secondarily-processed flue-cured tobacco laminas. The method comprises the specific steps that (1), before a tobacco leaf wetting process, the stem ratio of tobacco leaves of all processing levels is detected, according to the feeding matching ratio, the composite stem ratio is calculated, and on the premise that thatthe stem ratio is less than 1.8%, the stem ratio is between 1.8-3.0%, and the stem ratio is greater than 3.0%, tobacco leaves of mixed levels are divided into three types; (2), after the steps of on-line selecting, tobacco leaf wetting and impurity removing, the tobacco leaves of the mixed levels enter a tobacco leaf beating production line for beating four times, in each tobacco leaf beating process, whether or not a frame fence is arranged is determined firstly according to different stem ratios, and then a specific shape and size of the frame fence and the specific rotating speed of beatingrollers are set; (3), after the tobacco leaf beating process, the tobacco leaves are subjected to normal redrying, and tobacco stems are collected singly and put in boxes. The method is simple in technology, reasonable in design and high in operability, production and implementation are simple, the structure of the secondarily-processed flue-cured tobacco laminas is optimized, the stem removing intensity in the cigarette production process is reduced, and loss of cut tobacco is reduced in the stem removing process.

Description

technical field [0001] The invention belongs to the technical field of threshing and redrying of cigarettes, in particular to a threshing method for reducing the stalk content rate of secondary processed tobacco sheets. Background technique [0002] The scale of cigarette development tends to be stable. In order to ensure the steady growth of taxes and profits, it is the general trend to improve the quality and structure of cigarettes. Therefore, the development of cigarettes has higher requirements on the quality of raw materials, especially the rapid development of slim cigarettes, which has higher requirements on the quality of tobacco leaf raw materials. At present, there are two problems in the raw material supply of cigarette industrial enterprises. One is that the grade structure of raw materials in stock cannot meet the needs of cigarette brand structure; needs. Therefore, some industrial enterprises carry out secondary formula processing on raw materials of tobacc...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the high-end and slim cigarette raw materials in China are mainly purified by manual leaf selection to reduce impurities and reduce the stalk content in the leaves, but the cost of selection and processing is relatively high
