the heat exchange assembly comprises an evaporator 12 and a condenser 11, the evaporator 12 has a first end and a second end, the first end is arranged in the first cavity 21, the second end is arranged in the second cavity 22, the evaporator 12 is used for absorbing heat of the drying room 50, the condenser 11 has a third end and a fourth end, the third end is arranged in the third cavity 23, the fourth end is arranged in the second cavity 22 and is mutually overlapped with the second end of the evaporator 12, and the condenser 11 is used for heating the drying room 50.

Based on the above structure, when the ginseng is dried by the equipment, as the first partition board and the second partition board are arranged in the working cavity, the working cavity is divided into the first cavity 21, the second cavity 22 and the third cavity 23 by the first partition board and the second partition board, the drying room 50 is communicated with the second cavity 22, then the first end of the evaporator 12 in the heat exchange component is arranged in the first cavity 21, the second end of the evaporator 12 is arranged in the second cavity 22, the evaporator 12 is positioned between the first cavity 21 and the second cavity 22, and the third end of the condenser 11 is arranged in the third cavity 23, and the fourth end of the condenser 11 is arranged in the second cavity 22, so that the second end of the evaporator 12 and the fourth end of the condenser 11 can be overlapped and arranged in the second cavity 22, and the drying room 50 communicated with the second cavity 22 can be repeatedly subjected to heat exchange and drying.

Specifically, when the equipment is in operation, the condenser 11 starts to emit heat into the second cavity 22, and flows into the drying room 50 through the second cavity 22 to heat and dry the ginseng, the air humidity in the drying room 50 will be increased after drying, and at the moment, the air flows back into the second cavity 22, and then the evaporator 12 is utilized to absorb heat and dehumidify the ginseng, so that the ginseng is dried in a repeated cycle.

It should be noted that, in the drying process of the existing equipment, the drying temperature is generally controlled within a certain range and is only dried, and after the moisture contained in the ginseng is dried and evaporated, the air humidity in the environment of the drying room is increased, and the drying room is relatively closed because the heat loss needs to be reduced, so that when the moisture content in the air is saturated, the moisture in the ginseng is difficult to be emitted, no matter how high the temperature of the drying room is, if the moisture is not removed, once the heating is stopped, the temperature of the drying room is reduced, the ginseng is again wetted, the effect of the ginseng after drying is affected, and the quality of the ginseng is also affected.
