Tobacco leaf processing technology adopting stemming, slitting and redrying

Abstract

The invention relates to a tobacco leaf processing technology adopting stemming, slitting and redrying, and belongs to the technical field of tobacco processing. The processing technology provided bythe invention comprises the steps of material preparing and moisture regain, stemming and slitting, storage, tobacco leaf redrying and packaging, and tobacco steam redrying and packaging, wherein during static moisture regain, vacuum moisture regain and mesh belt moisture regain are matched for controlling the moisture and temperature of tobacco leaves, and stemming and slitting replace the traditional leaf-threshing air separating; and after stemming and slitting, tobacco leaves and tobacco stems respectively enter a leaf storage cabinet and a steam storage cabinet to be temporarily stored for moisture balancing and production, and redrying, boxing, cooling-packaging and warehousing are respectively carried out. According to the processing technology, static moisture regain replaces roller moisture regain, roll screening replaces roll sand screening, stemming and slitting replace threshing air separating, a group of storage feeding is reduced, then the problems that the threshing redrying production line is high in energy consumption, large in occupied area, large in tobacco leaf loss, large in noise, large in dust mount, and the like are solved, and the technology has the advantages of low investment and high yield.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a processing technology for stalk-cutting and re-curing tobacco leaves. Background technique [0002] In the tobacco processing industry, the processing technology of “threshing the original tobacco leaves and redrying the sliced ​​tobacco” is generally used (see attached figure 1 ), the process is long, there are many drum-type equipment, large energy consumption, large loss of tobacco leaves, high noise, large dust, large space occupation, and with the widespread use of high-speed cigarette machines, higher requirements are put forward for the length of shredded tobacco , Tobacco can neither be too long nor too short. Therefore, in order to achieve the goal of "controlling the rate of large slices and increasing the rate of medium slices" while ensuring the separation of leaf stems, it is necessary to increase the number of threshing times. Most of the c...

Problems solved by technology

[0004] In order to overcome the problems existing in the background technology, the present invention provides a processing technology of stem-drawing, slit-cutting and re-curing tobacco leaves, which uses vacuum re-moisture and net-belt re-moisture instead of vacuum re-moisture, roller sieve instead of drum sieve, Cutting instead of threshing air separation, reducing a group of storage and feeding materials, effectively solving the problems of high energy consumption, large space occupation, difficult control of temperature and moisture when tobacco leaves rehydrate, difficulty in controlling the size of tobacco leaves and tobacco stems, and difficulty in the production of threshing and redrying. Problems such as large loss, high noise, and large dust have the advantages of low input and high output
