Description

[0002] In recent years, new methods of dry-process reconstituted tobacco have gradually attracted people's attention. This new method draws on the papermaking process to develop a new type of reconstituted tobacco production technology. Its process includes the steps of anhydrous decomposition of wood pulp fiber to make a sheet base, low-temperature crushing pretreatment of tobacco raw materials, preparation of coating liquid, coating the sheet base with the coating liquid, and drying and slicing to form the final product. Dry-process reconstituted tobacco plays an important role in cigarette production. It can not only reduce the cost of cigarettes, but also improve the intrinsic quality of cigarettes.

[0003] Among them, the spraying process is a very important process in the process of dry reconstituted tobacco leaves. The spraying process refers to spraying the spray liquid evenly on the surface of the tire paper to prepare for the next baking process. The spraying amount during the spraying process is directly related to the quality of the finished tobacco leaves.

[0004] At present, the single fixed spraying method is more commonly used in the spraying process, that is, the nozzle is fixed at the corresponding position to spray the tire paper at a certain angle. This spraying method sometimes causes the spray liquid on the tire paper surface to be unevenly distributed, thereby reducing the spraying pass rate, causing material waste and increasing the company's production costs.

[0005] In summary, how to solve the problem of low qualified rate caused by uneven spraying of tire paper is an urgent problem to be solved by those skilled in the art. Summary of the invention
