Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tobacco leaf curing processing, and particularly relates to a box type curing and moisture recovery equipment. BACKGROUND

[0002] Tobacco leaf curing is a tobacco leaf curing method in which tobacco leaves of the same variety, same part and same maturity are sent into a curing room through pole weaving and tobacco loading according to temperature and humidity control according to the quality of the tobacco leaves, by heating and ventilation measures in a special curing room.

[0003] In tobacco leaf curing, the cured tobacco leaves all need to be subjected to a moisture recovery softening process. Since existing tobacco leaf curing rooms basically do not have a tobacco leaf moisture recovery device, the moisture recovery of the tobacco leaves can only be achieved by natural moisture recovery and manual moisture recovery. Since the air humidity in some tobacco leaf planting areas is low, the time for the natural moisture recovery of the cured tobacco leaves is too long, which not only leads to low production efficiency, but also causes the mold of the tobacco leaves. The manual moisture recovery that is currently used more frequently is to manually spray water in the curing room to accelerate the moisture recovery of the tobacco leaves after the curing of the tobacco leaves is completed. This also has the problems of long time consumption (more than one day) and low efficiency, and cannot truly meet the needs of the moisture recovery of the tobacco leaves.

[0004] In traditional tobacco leaf curing, the tobacco leaves usually need to be manually pole woven by the tobacco farmers, which is time-consuming and laborious. The curing and moisture recovery often need to be performed according to the weather conditions, which easily leads to the fragmentation and mold of the tobacco leaves. In addition, since the temperature, wind speed and humidity inside the curing space are different, the curing degree of the tobacco leaves at different positions is also different, which greatly affects the quality of the tobacco.
