technical field

The invention relates to the field of tobacco processing equipment, in particular to a drying device for tobacco processing.

Background technique

The tobacco industry generally refers to the processing industry that uses tobacco as raw material to make various tobacco products. The tobacco products include cigarettes, cigars, shredded tobacco, snuff and chewing tobacco. Among them, cigarettes have the largest output and consume more than 85% of the total tobacco leaves Therefore, the tobacco industry mainly refers to the cigarette industry. Due to the wide consumption of cigarettes, large volume and high tax, the cigarette industry occupies an important position in the economies of various countries. Tobacco drying is an essential part of the tobacco industry. At present, after the tobacco leaves are shredded, the pectin in the tobacco leaves will flow out, which will cause the shredded tobacco to stick together, making it very inconvenient to dry the tobacco, and the tobacco cannot be completely dried. After being dried, the quality of tobacco products will be greatly reduced.
