Abstract

The invention relates to a defibrating process for tobacco sheets. It includes the following steps: (1) sorting, removing impurities, and pulverizing the tobacco stems or tobacco leaf fragments for pretreatment; (2) soaking and extracting the raw materials after the above treatment; (3) performing solid-liquid separation on the extract, and The insoluble matter in the aqueous solution is separated, and the obtained fiber is soaked and washed with lye and then treated with acid solution to neutrality; (4) the obtained fiber slurry is mixed with dry fiber, and the amount of dry fiber added is the total amount of fiber slurry (5) distilling and concentrating the extract obtained in step (2), dipping or spraying the obtained tobacco concentrate on the sheet base, and finally drying it to become a tobacco sheet. The tobacco sheet prepared by defibrating in the present invention has good mechanical strength, less alkali residue, and better smoking taste than products obtained by simple mechanical defibrating and chemical defibrating.

Description

technical field [0001] The invention relates to the technical field of manufacturing reconstituted tobacco leaves, in particular to a defibrating process of tobacco sheets. Background technique [0002] Tobacco sheet, also known as recombined tobacco and regenerated tobacco, is made of tobacco waste materials in the process of redrying and cigarette production, such as tobacco stems, tobacco powder, cigarette sticks, tobacco leaf fragments and some low-grade tobacco leaves, etc., after recombination processing. regenerated tobacco leaves. On the one hand, the raw materials of tobacco leaves can be utilized to the greatest extent, and the cost of cigarettes can be saved; on the other hand, tobacco sheets can reduce the release of tar in cigarettes. played an important role in reducing the harm of cigarettes. The production methods of existing tobacco sheets mainly contain thick pulp method and papermaking method, especially the latter method occupies more and more important...
