Abstract

The invention relates to a drying system for tobacco and a control method for tobacco. The drying system comprises a refrigeration main loop, the refrigeration main loop comprises a fixed frequency compressor, a condenser, a first expansion device and an evaporator which are sequentially connected through a refrigerant pipeline, the condenser is configured to provide drying air for tobacco arranged in a preset space, and a first control valve is arranged between the condenser and the first expansion device; and the bypass branch is provided with a first end located between the condenser and the first control valve and a second end located between the first expansion device and the evaporator, and a second control valve, a liquid storage device and a second expansion device are sequentially arranged on the bypass branch in the flowing direction of the refrigerant. The invention further provides a tobacco control method. And when the condition of entering the ventilation and moisture removal mode is met, the bypass branch is opened, the refrigeration main loop is closed, the refrigerant amount in the refrigeration system is reduced, the running time of the fixed-frequency compressor is prolonged, and frequent starting and stopping of the fixed-frequency compressor are prevented.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a drying system for tobacco and a control method for tobacco. Background technique [0002] Drying system refers to a combination of equipment that uses thermal energy to dry materials with high moisture content. According to the different forms of heat energy generation, drying systems can be divided into electric heating, gas, fuel, coal, heat pump and other types. Compared with the traditional fuel drying system, the heat pump drying system has the advantages of energy saving, high efficiency, environmental friendliness and low operating cost, so it is widely used in many fields such as tobacco processing, grain storage, metallurgy and chemical industry. [0003] In the process of tobacco processing, the heat pump drying system can accurately adjust the temperature and humidity in the drying room, thereby effectively improving the efficiency of flue-cured tob...
