The working principle of the edible fungus dryer is to use the reverse Carnot principle. The refrigerant (mostly mixed refrigerant) is compressed by the compressor and becomes a high-temperature and high-pressure gas. The gas temperature can reach 100-110 °C. The pipeline (copper tube) enters the heat exchanger (condenser), and then the heat generated by the heat exchanger (condenser) is sent to the drying room through the fan to heat and dry the material.
It can be understood that the principle of a heat pump dryer is similar to that of the home air conditioner. The home air conditioner is divided into an indoor unit and outdoor unit. When the air conditioner is refrigerating, the indoor unit continuously provides cold air to the room, and the outdoor unit is also continuously discharging. hot air. Then, the working principle of the edible mushroom dryer is the same as that of the air conditioner, except that what we need is the hot air it discharges (of course, the temperature of the hot air discharged by the air conditioner is lower, and the hot air discharged by the edible mushroom dryer is high).
