Description

System and method for preparing thick slurry method sheet slurry for heating cigarettes Technical Field The application relates to the technical field of tobacco processing, in particular to a system and a method for preparing thick slurry-method sheet slurry for heating cigarettes. Background The tobacco sheet is one of important raw materials of tobacco products, and the preparation method thereof can be roughly classified into a rolling method, a thick pulp method and a papermaking method according to the process. The thick pulp sheet is prepared through crushing tobacco material into 80-300 mesh tobacco powder to form material I, hydraulic crushing fiber board, grinding to form material II, mixing the material I, material II, adhesive, glycerin, perfume and other supplementary material to form slurry, spreading the slurry onto steel belt via casting, scraping, roller coating, etc to form, drying, stripping and cutting or winding. The thick pulp sheet for heating cigarettes (i.e. heating non-combustible cigarettes, heat Not Burning, HNB) can contain an atomizing agent, wherein the atomizing agent mainly comprises glycerin and propylene glycol, and is generally added in the pulp preparation link of the thick pulp sheet. In the process, the tobacco raw material is generally crushed by a dry method, and the dry tobacco powder is difficult to deteriorate in storage and has small storage volume, and the complete tobacco raw material formula can be crushed at one time, stirred and homogenized and then used in batches, so that the method is suitable for small-scale production. The dry method crushing method has the disadvantages that the raw materials are generally required to be pre-dried for moisture adjustment to ensure the crushing quality, corresponding dust removing pipelines and dust removing equipment are additionally arranged in the crushing process, and meanwhile, the processing environment and equipment are required to meet the dust explosion-proof requirement due to smaller crushing particle size. The disadvantages are that for laboratory sample preparation without batch pulping and large-capacity large-scale production, the additional requirements of dust removal, explosion prevention and the like are higher for the requirements of places and equipment investment. In addition, under the background that the market scale of the heating cigarettes is continuously enlarged and the taste demands are increasingly diversified, the raw materials of the heating cigarette flakes are not only limited to the offcuts of the traditional cigarette manufacturing such as the traditional tobacco fragments, the crushed powder and the like, but also high-quality boxed sheet cigarette raw materials are widely used. Under the condition that the boxed sheet tobacco exists in the raw material formula, the sheet tobacco raw material which is not loosened cannot effectively remove impurities through spectrum impurity removing equipment in the traditional cigarette shredding process, and the raw material is easy to be polluted after the impurities are crushed, so that the sheet products generate peculiar smell and the like. Disclosure of Invention The application aims to provide a preparation system and a preparation method of thick slurry method flake slurry for heating cigarettes, which improve the crushing efficiency and the yield of tobacco powder, reduce dust removal and dust explosion prevention equipment, facilitate clean production, reduce cost and the like.
