Abstract

The invention relates to the field of drying equipment, in particular to a heat exchange drying device. Heating drying and dehumidification functions can be achieved at the same time, and energy can be saved. The heat exchange drying device comprises a drying chamber and a heat exchange device. The drying chamber is provided with a drying heat exchanger. The heat exchange device is connected withthe drying heat exchanger and comprises a heat exchange unit and a cold and hot switching device. The cold and hot switching device is arranged between the heat exchange unit and a drying heat exchanger. The heat exchange unit can use a compressor unit, and refrigeration and heating are conducted simultaneously. Working states of the drying heat exchanger can be changed directly through the cold and hot switching device. Products can be dried through the heating mode. The refrigeration mode can be used for dehumidification.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a heat exchange drying device. Background technique [0002] In the prior art, common drying equipment uses high-temperature air to accelerate the evaporation of water in the product to achieve drying, but the humidity in the air after drying is extremely high, and it is necessary to collect the water in the air in time, otherwise it will be re- Back to the product, affecting the drying effect of the product. During the drying process, it is necessary to set up a dehumidification device to collect and discharge the water vapor in the air. The additional dehumidification device increases the manufacturing cost of the equipment. In addition, since the moisture content in the air changes during the drying process, it is difficult to control the working conditions of the dehumidification equipment, resulting in increased energy consumption. [0003] Patent No. 201520673372.0 Chinese...
