Problems solved by technology

[0003] At present, the problem of sticking in the storage of tobacco sheets in the production process of tobacco sheets is a major problem in the storage and use of tobacco sheets. Due to the large amount of tobacco sheet production, it generally needs to be stored for 2-3 months. The phenomenon of adhesion will occur during storage. There are two main reasons. One, a tobacco sheet is relatively flat, after extrusion, the contact area is large, and because the tobacco sheet has a high water content, it will stick after being placed for a long time. The second reason is that the tobacco sheet itself contains water, and there is no Very good diaphragm, molecular movement leads to adhesions

Abstract

The invention discloses a method for preventing tobacco sheets from being adhered during storage. The method comprises the following steps of spraying a protective agent to the tobacco sheets, drying,and modelling the tobacco sheets. The contact area of the sheets is reduced, the pressure-withstanding elasticity of the sheets is improved, a film-forming property between the tobacco sheets is improved, molecular movement of a tobacco sheet contact surface is blocked, and meanwhile, the content of moisture in the tobacco sheets can be further reduced, so that adhesion is reduced.

Description

technical field [0001] The invention relates to the field of tobacco sheets, in particular to a method for preventing the storage of tobacco sheets from conglutination. Background technique [0002] Tobacco sheet is one of the important raw materials of cigarette products, which has a great impact on the quality of cigarette products. At the same time, it is also the main raw material of new heat-not-burn tobacco products. [0003] At present, the problem of sticking in the storage of tobacco sheets in the production process of tobacco sheets is a major problem in the storage and use of tobacco sheets. Due to the large amount of tobacco sheet production, it generally needs to be stored for 2-3 months. The phenomenon of adhesion will occur during storage. There are two main reasons.
