Tobacco leaf threshing and redrying and impurity winnowing processing technology and equipment

Abstract

The invention discloses a tobacco leaf threshing and redrying and impurity winnowing processing technology and equipment. The tobacco leaf processing technology comprises the following steps of winnowing a tobacco leaf material which is moisturized with hot air to obtain a tobacco leaf main material and tobacco leaf impurities, keeping the tobacco leaf main material on a tobacco leaf main material production line, and manually removing impurities from the separated tobacco leaf impurities to obtain a tobacco leaf residual material. The technology is characterized in that the tobacco leaf residual material and the tobacco leaf main material are kept in a separated state, the tobacco leaf residual material is conveyed to a fragment drying unit, and the tobacco leaf residual material and fragments are dried, screened and packaged together. The tobacco leaf residual material obtained through winnowing and impurity removal is separated, and the quality of the tobacco leaf main material is guaranteed, so that the quality of cigarette products is improved.

Description

technical field [0001] The invention relates to a tobacco leaf treatment process and equipment, more specifically to a process and equipment for treating tobacco leaves by winnowing and removing impurities during the threshing and redrying process. Background technique [0002] In the cigarette production industry, the technological process for air separation and impurity removal tobacco leaves in the prior art tobacco leaf threshing and redrying production process is: firstly carry out air separation for the tobacco leaf raw materials after hot air moistening, and sort out the main tobacco leaves and tobacco leaf miscellaneous materials, the main tobacco leaf materials are kept on the tobacco leaf main material production line, and the separated tobacco leaf miscellaneous materials are manually removed, and the impurities removed are the tobacco leaf residues. At present, the treatment of tobacco leaf residues is to return them to the tobacco leaf main material production l...

AI Technical Summary

Problems solved by technology

Since the sorting process adopts the method of winnowing, the tobacco miscellaneous materials sorted out in actual production are characterized by light weight, small pieces, weather spots, scorch, and damage. Tobacco leaves with edges, lesions, damages, burnt tips and burnt edges, and a small amount of residual debris, such tobacco residues are significantly different from the main tobacco leaves in terms of appearance quality, physical and chemical indicators, leaf structure, sensory quality, etc. , the overall quality is worse than that of the main tobacco leaf material, which leads to negative effects on the smoking quality, uniformity, purity, leaf structure, conventional chemical composition, and moisture content stability of the tobacco leaf after mixing the tobacco leaf residue, thus affecting the later stage. The use of tobacco leaves by cigarette companies
