At present, the commonly used drying methods include natural air drying and heating drying. Natural air drying takes a long time and is easily affected by the weather, resulting in low work efficiency and inconvenient operation. However, heating and drying often use drying equipment for drying, for example, The Chinese patent application number 201420256575.5 discloses a layered electric heating dryer. The upper part of the box of the device has a channel partition separating the upper and lower layers. Above the channel partition is a return air channel. Between the channel partitions The lower box is provided with two rows of spaced brackets for placing material trays. There is a circulating air duct between the brackets and the box.

The fan is connected to the control system through a frequency converter to adjust the air supply volume. When the device is working, the hot air is discharged outward, resulting in low resource utilization and high energy consumption in production. In addition, the commonly used drying equipment does not have the function of cooling Chinese medicinal materials. After drying, it is often placed in the air for cooling and then sealed. During the cooling process, it is easy to be damp again, which affects the drying effect. At the same time, the medicines in the drying rotary bin are easy to collide with each other to generate dust, so this method is not applicable Fragile traditional Chinese medicine, the scope of use is small.
