Description

Technical Field

[0001] This utility model relates to the field of tobacco processing machinery technology, specifically to a continuous vacuum leaf moistening device for tobacco leaves. Background Technology

[0002] Tobacco leaf moistening refers to the process of heating and humidifying tobacco leaves during tobacco processing to enhance their toughness and processing resistance. The main purpose of moistening is to make the tobacco leaves soft and loose, increasing their toughness and resistance to breakage, thereby improving the quality of threshing and destemming. Vacuum moistening is a method that uses steam to rehydrate tobacco leaves under vacuum conditions to improve their physical and chemical properties. However, existing moistening equipment suffers from uneven contact between steam and tobacco leaves during processing, and steam condenses at the bottom, soaking the leaves and damaging them.
