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

A method for preventing sticking of tobacco sheets disclosed in the present invention comprises the following steps: spraying a protective agent on the tobacco sheets and drying them, shaping the tobacco sheets, reducing the contact area of ​​the sheets, increasing the pressure resistance elasticity of the sheets, and increasing the The film-forming properties between the sheets block the molecular movement of the contact surface of the tobacco sheets, and can also reduce the moisture content in the tobacco sheets to reduce adhesion.

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.
