Description

Technical Field

[0001] The utility model belongs to the technical field of dehydration and drying equipment, and specifically relates to an air source heat pump tobacco drying machine. Background Art

[0002] The existing air source heat pump dryer includes air source heat pump split dryer, which can be divided into air source heat pump main unit evaporator system according to actual situation. The heat pump absorbed from the ambient air is sent into the condenser in the baking room through the connecting pipe. The heat of the condenser is continuously used to produce hot and cold cycle through the condensing circulation fan, and the temperature is continuously increased, so that the moisture in the baking room is evaporated into water vapor by heat, and then the wet steam in the baking room is discharged out of the baking room through the dehumidification fan installed on the baking room according to the requirements of process dehumidification. With the change of process, the temperature in the baking room continues to rise, and the moisture in the body is also reduced by steam. After reciprocating heating and dehumidification, it is gradually dehydrated and dry. The core is to heat and use the principle of dehumidification fan to discharge the moisture in the baking room out of the baking room, also commonly known as: active dehumidification method, the baking machine is equipped with a fresh air louver air valve, which is synchronized with the dehumidification fan during dehumidification to ensure the pressure balance in the baking room.

[0003] However, the current air source heat pump dryers are either equipped with a dehumidification fan on the main unit or on the drying room. In short, drying and dehumidification are inseparable from the role of the dehumidification fan, which undoubtedly increases the cost and damages the structure of the drying room.

[0004] In short, there is no air source heat pump dryer that uses the condensing fan installed in the heating chamber of the drying room to produce the positive and negative pressure difference principle to achieve unpowered dehumidification. Utility Model Content

[0005] In order to solve at least one technical problem existing in the background technology, the dehumidification system of the utility model removes the dehumidification fan, thereby reducing the cost.
