Problems solved by technology

[0004] In the above public reports, the application forms of tobacco stems in coated white cardboard can be divided into tobacco stem pulp and tobacco stem powder. Among them, tobacco stem powder is directly added to the production process of coated white cardboard, which will cause a large amount of tobacco waste water , the pretreatment process of tobacco stem powder is cumbersome, the treatment efficiency is low, and the cost is high; the tobacco stem pulp can be continuously added online in the production process of coated white cardboard, but the publicly reported tobacco stem chemical pulp needs to use a large amount of cooking chemicals, and the yield of tobacco stem pulp is low

Abstract

The invention discloses a tobacco stem pulp sheet preparation method, and belongs to the field of processing and recycling of cigarette byproducts. The preparation method comprises the following steps: (1) extracting; (2) carrying out solid-phase filter pressing; (3) carrying out high-concentration pulping; (4) preparing pulp; (5)carrying out pulp screening; (6) forming on a net; and (7) drying. The invention further discloses the tobacco stem pulp sheet obtained through the preparation method and application of the tobacco stem pulp sheet. The tobacco stem pulp sheet belongs to mechanical pulp, compared with tobacco stem chemical pulp, chemicals are not needed in the production process, production is environmentally friendly, the pulping yield is high, and the tobacco stem pulp sheet is convenient to store and transport. The tobacco stem pulp disclosed by the invention can be added and used on a surface layer or a core layer or a bottom layer of a coated ivory board on line.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a tobacco stem pulp sheet, its preparation method and application. Background technique [0002] Tobacco stem is an important by-product in the process of tobacco processing. Because it has similar components to tobacco leaves and has the functions of improving cigarette structure, reducing cost and reducing coke, it has always been an important part of cigarette raw materials. Currently, cigarette industry enterprises use The tobacco stems are mainly shredded stems and reconstituted tobacco leaves. With the continuous innovation in the processing technology of reconstituted tobacco leaves and shredded tobacco stems, the quality of reconstituted tobacco leaves and shredded tobacco stems has been greatly improved, and its application range and proportion in cigarette products are also increasing. Nevertheless, various cigarette industrial enterprises still have a larg...
