A storage cavity 5 is arranged between the partition plate 4 and the heating component 3. A water intake component 6 is installed on the partition plate 4.
[0022] In the present utility model, with the curing barn main body 1 as the device main body, during use, the tobacco leaves are placed on the mesh plate 8 for normal drying. When moisture regain is required, first add water to the inside of the storage cavity 5, and then start the water intake component 6 to first descend, so that the water overflows upward to the upper side of the water intake component 6 and cannot flow back downward. Then start the water intake component 6 to rise until it contacts the bottom of the heating component 3, so that the bottom of the heating component 3 is immersed in water. Since the water intake of the water intake component 6 can be adjusted according to different descending distances, the required amount of water can be accurately taken. Then start the heating component 3 to heat the water to generate water vapor that rises evenly to carry out moisture regain on the tobacco leaves. At the same time, start the circulation component 2 to drive the water vapor to continuously circulate in the space above the tobacco leaves, thereby realizing the advantages that the device has high-efficiency moisture regain, uniform moisture regain and improved moisture regain efficiency, and solving the problems in the prior art that only by heating water under the tobacco rack to generate steam and the steam spreads freely to carry out moisture regain on the tobacco leaves, this method takes a long time and the tobacco leaves have uneven moisture regain, and it is difficult to control the generation amount of water vapor and the efficiency is low.
