Title:
TOBACCO DRYING DEVICE AND TOBACCO DRYING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/227871
Kind Code:
A1
Abstract:
A tobacco drying device and a tobacco drying method. The method comprises: during a moisture regain control process, acquiring the real-time air humidity in a drying room (306); when the real-time air humidity is less than a lower-limit humidity threshold value, executing the following first control process: controlling a heat pump dryer to run a heating mode, and also controlling a water spraying apparatus to spray water onto the surface of an indoor heat exchanger (302) of the heat pump dryer at a first flow rate; when the real-time humidity is not less than the lower-limit humidity threshold value and is less than an upper-limit humidity threshold value, executing the following second control process: controlling the water spraying apparatus to spray water onto the surface of the indoor heat exchanger (302), wherein a water spraying rate is determined according to the real-time air temperature in the drying room (306); and when the real-time humidity is not less than the upper-limit humidity threshold value, executing the following third control process: controlling the water spraying apparatus to stop spraying water. By means of the method, the moisten regain efficiency and reliability can be improved, thereby improving the quality of tobacco.
