Description

Square roast room that removes of two-way air current

Technical Field

The utility model relates to a cigarette making equipment technical field specifically is a square roast room that removes of two-way air current.

Background

Tobacco leaf is roasted, and the temperature and humidity of the roasting room are regulated through heating and ventilation measures in a special roasting room. Tobacco leaves of the same variety, the same part and consistent maturity are sent into a curing barn through rod weaving and tobacco loading, and the temperature and the humidity are controlled according to the quality of the tobacco leaves. Generally, the leaves wither and turn yellow after being dehydrated at 35-38 ℃; the leaves basically turn yellow and completely wither at the temperature of 41-42 ℃, and the main pulse is soft; yellow tablets, yellow ribs and small drums are obtained at the temperature of 46-48 ℃; reaching 54-55 ℃ to a large reel. Normal tobacco leaves are mainly baked in three stages (namely yellowing, fixing color and drying ribs). The yellowing stage is to make tobacco leaf yellow and soft, main pulse soft, starch and protein hydrolyze, soluble sugar and organic acid increase, ammonia odor dissipate, nicotine content decrease; in the color fixing stage, the leaves are dried, and the existing color and quality are fixed and maintained to achieve yellow and soft leaves; the stem drying stage is to dry all the main veins of the tobacco leaves.
