Description

Technical Field

[0001] The utility model relates to the technical field of flue-cured tobacco baking equipment, in particular to an energy-saving flue-cured tobacco baking device. Background Art

[0002] During the tobacco baking process, external heat (heating equipment) is needed to provide the temperature required for baking, and a dehumidification system is needed to discharge the moisture produced by baking. Usually, the baking time of a furnace of tobacco is 160 to 190 hours. During the tobacco baking process, the heat lost through ground heat conduction cannot be underestimated.

[0003] At present, most of the flue-curing houses used for tobacco leaf curing use concrete cast cement floors. This method can discharge the excess water generated during the curing process through the ground, but at the same time, a large part of the heat is also lost through the ground, resulting in energy waste. There are also thermal insulation materials laid on the ground to reduce the heat loss of the ground, but this method blocks the water absorption and moisture removal of the ground and its dehumidification system, prolongs the curing time, and increases the energy consumption of curing. In addition, there is also a method of laying thermal insulation materials before the ground is poured. This method can reduce the heat loss of the ground, and can also reduce the humidity of the curing house by absorbing water from the ground. For example, in an energy-saving flue-curing house with a publication number of CN209643834U, the motor controller is started to expand the button, and the insulation pad is laid on the floor of the curing room, which mainly plays a role of heat preservation; during the color setting period, the motor controller is started to close the button, and the insulation pad is stored in the reel, but the insulation pad in the energy-saving flue-curing house is set with a motor to control the reel except for one side of the reel. Even if the motor output shaft rotates in the opposite direction, the insulation pad cannot be automatically unfolded and laid to one side, and needs to be manually unfolded, which is less practical.

[0004] Therefore, it is necessary to provide a flue-cured tobacco energy-saving baking device to solve the above technical problems. Utility Model Content
