Bulk curing barn capable of effectively recycling heat energy

The utility model discloses a bulk curing barn capable of effectively recycling heat energy. The bulk curing barn comprises a curing barn body, a humidity elimination window and a heating chamber. The heating chamber is provided with an observation window. The humidity elimination window is communicated with a heat inlet pipe. The heat inlet pipe is communicated with a water-heat separation device. The other end of the water-heat separation device is connected with a heat supply pipe. The heat supply pipe is communicated with the heating chamber. The water-heat separation device is arranged outside the curing barn body. According to the bulk curing barn, the water-heat separation device is arranged outside the curing barn body, and the heat energy is recycled through the structure that a pipeline is connected to the humidity elimination window. A large number of tests in production prove that firstly, after the water-heat separation device is mounted on the bulk curing barn, the tobacco curing time is shortened, the amount of coal used for curing is lowered, consumed electricity is reduced, and labor cost is greatly lowered; secondly, tobacco leaves turn yellow fully in the curing process, the number of damaged tobacco leaves is small, and green smoke is not prone to generation; thirdly, the temperature difference in the curing barn is small during tobacco curing, tobacco leaves with ash are eliminated, the difference between the color of the obverse sides of the tobacco leaves and the color of the reverse sides of the tobacco leaves is small, main veins of the tobacco leaves turn yellow fully, and therefore the quality of the tobacco leaves is greatly improved.
