After the clamping connection parts are arranged, the transverse rods can be connected to different height positions on the vertical rods in a clamping mode, requirements of tobacco leaves of different dimensions and sizes are met, and tobacco leaves can not fall onto the ground after being fixed. Alcohol groups are used as fuel of the alcohol-based fuel heating device and are environmentally friendly and clean, the alcohol-based fuel tobacco curing house has the advantages that the house is clean, sanitary, safe, low in price and convenient to use, and raw materials are easy to purchase, and alcohol-based fuel is biomass clean energy encouraged by China to be developed. Meanwhile, the tobacco curing house is provided with a humidity collection system and is beneficial to humidity management and control.

The invention provides a face-to-face blowing type double-circulation air curtain unit, and belongs to the technical field of refrigeration houses. The face-to-face blowing type double-circulation aircurtain unit comprises a first case and a second case which are oppositely arranged. A first fan and a third fan are arranged on the first case. A first opening communicating with an inner cavity ofthe first case is formed in the first case. A second fan is arranged on the second case. A second opening and a third opening which communicate with an inner cavity of the second case are formed in the second case. The first fan is opposite to the second opening. The second fan is opposite to the first opening. The third fan is opposite to the third opening. According to the face-to-face blowing type double-circulation air curtain unit, double circulation of air flow can be achieved, cyclically-flowing air can better prevent cold air in a refrigeration house from flowing out and prevent hot air outside the refrigeration house from entering the refrigeration house, and a better blocking effect is achieved; and the face-to-face blowing type double-circulation air curtain unit has a better heat insulation effect and can save more energy.
