Description

Device for humidifying tobacco leaves by utilizing damp and hot air of curing barn
Technical Field
The utility model belongs to the technical field of the tobacco baking equipment, concretely relates to simple structure, use convenient, with low costs, the device of the humid hot air conditioning tobacco leaf in roast room of low energy consumption.
Background
The method comprises the following steps of collecting fresh tobacco leaves, baking the fresh tobacco leaves in a bulk curing barn, and after a yellowing period, a color fixing period and a drying period, the moisture content of the tobacco leaves is generally 5-8%, so that the tobacco leaves are easy to break if being directly taken out of the curing barn, the yield and the quality of the tobacco leaves are reduced, and the loss is large. In order to solve the problem of low water content of the baked tobacco leaves, the baked tobacco leaves must be subjected to moisture regain treatment to enable the water content of the tobacco leaves to reach 14-18%, meanwhile, the tobacco leaves are soft, tough and easy to loosen by increasing the temperature, the crushing loss in the tobacco leaf processing process is reduced, and the green miscellaneous gas and other bad smell of the tobacco leaves can be reduced to some extent after moisture regain, so that the tobacco shred making quality is improved.
At present, natural moisture regain and forced moisture regain are available as moisture regain methods. And (4) natural moisture regaining, namely after the tobacco leaves are baked, opening the door of the baking room and regaining moisture by virtue of dew at night. The method has the problems of long time, unstable moisture of tobacco leaves, serious breakage, low efficiency and the like during the moisture return. The forced moisture regaining mode is carried out by adopting a moisture regaining machine, and comprises cold water moisture regaining and steam moisture regaining, although the moisture regaining machine has the advantages of convenient operation, better atomization effect, time and labor saving and is popular with tobacco growers. However, when the tobacco leaves are subjected to cold water moisture regain, the water absorption of the tobacco leaves is seriously reduced in a low-temperature environment, the moisture regain effect is poor, the combustibility of cigarettes made of the tobacco leaves subjected to moisture regain is poor, and the tar content generated during the burning of the cigarettes is high. The steam dampening is to evaporate water into steam at high temperature, and the steam is dampened through the air inlet, which requires a large amount of energy consumption and has higher cost. In addition, forced moisture regain among the prior art is usually to place the damping machine in the roast room, transfers the fan to reversing and remoistens, and the damping machine is in the work of higher humidity environment this moment, has significantly reduced its life, and because the damping machine atomizing export is close to the tobacco leaf, leads to local humidity too big, has caused partial tobacco leaf to regain excessively, has influenced tobacco leaf quality.
