The heat exchanger 20 is connected with the dehumidification device 11 arranged at the rear of the drying box 10, and cools the hot moisture delivered by the dehumidification device 11 into cold air and cold water, and the cold air is transported to the microwave device through the cold air delivery pipeline 30 for one heating.

The heat exchanger 20 receives the hot moisture delivered by the dehumidifier 11 located at the rear of the drying system, cools the hot moisture into cold air and cold water, and sends the cold air to the microwave device 30 through the cold air delivery pipeline. The drying system of the embodiment of the present application may also include a cooling water recovery tank, and the cold water generated after the heat exchanger 20 cools the hot moisture is collected by the cooling water recovery tank, and the collected cold water can be recycled for production raw material.

The microwave device 30 heats the cold air delivered by the heat exchanger 20 once, and sends the hot air generated by the first heating to the solar heat collector 40 for secondary heating. The cold air entering the microwave device 30 also serves to cool down the magnetron and transformer in the microwave device 30 to prevent components such as the magnetron or transformer from being damaged due to high temperature. In the embodiment of the present application, the primary hot air delivery pipeline includes a plurality of thin pipes, and the primary hot air is divided into multiple streams through the thin pipes and enters the solar heat collecting device 40 .
