Problems solved by technology
Therefore, in the currently used intensive curing barns, the tobacco leaves after roasting are prone to appear light and smooth in color, resulting in a decrease in oil content and aroma, etc., affecting the quality of the tobacco leaves.
[0003] In addition, in terms of energy consumption in baking, the currently used intensive barns adopt an open dehumidification method, which not only causes the loss of a large amount of aroma components of tobacco leaves, but also causes a large loss of residual heat in the dehumidification airflow
Therefore, the energy utilization rate of the current intensive curing barns is generally low, making the energy consumption of tobacco leaf curing high, and the coal consumption per kilogram of dry tobacco leaves is about 1.5-2.0 kg

The invention relates to a fully closed hot air circulation intensive curing room and belongs to the technical field of tobacco modulation. Add a partition-type air-cooled dehumidifier, dehumidified air outflow duct, fresh air outlet duct, dehumidifying air flow fan, fresh air inlet duct, drainage pipe, and fresh air fan to the fully closed hot air circulation intensive baking room; at the same time, cancel the moisture discharge outlet . The invention adopts a fully closed hot air circulation, and all the hot air in the dense curing room is recycled; when the curing room is dehumidified, the aroma components of the tobacco leaves volatilized during the baking process of the tobacco leaves and other components that are beneficial to improving the baking quality of the tobacco leaves can be removed. The gas components are fixed in the intensive curing room; compared with the current intensive curing room, it can not only avoid the loss of waste heat of the dehumidification air flow, but also effectively improve the quality of tobacco leaf baking.
Description
technical field [0001] The invention relates to a fully-closed hot air circulation intensive curing barn, which belongs to the technical field of tobacco preparation. Background technique [0002] Curing is a key factor in determining the quality and usability of tobacco leaves. Advanced tobacco leaf curing equipment is the basis for accurately realizing the scientific curing process, improving the quality of tobacco leaves, and reducing labor intensity and production costs. Compared with the traditional barn, the main features of the intensive barn include: 1) Large capacity of smoke, which is 2-3 times of the smoke density of ordinary barn; 2) Forced ventilation with air supply fan; 3) Hot air circulation ; 4) Strong controllability of temperature and humidity. Due to the above-mentioned characteristics of the intensive barn, it has been widely used in smoking areas all over the country. However, the currently used intensive barns adopt an open dehumidification meth...
