Background technique

Drying of Chinese medicinal materials is a processing procedure for dehydrating Chinese medicinal materials, maintaining their original ingredients and maintaining their medicinal properties. Drying is to allow them to be stored for a long time. At present, drying of medicinal materials is mostly operated by dryers. , The main principle of the medicinal material dryer used in the drying process is to use the heat pump evaporator to absorb the heat in the outside air, or to recover the waste heat of the exhaust gas during the drying process, and to work through the compressor to transport (transfer) the energy to the drying box. , the hot air in the drying box is heated through repeated cycles, absorbs the moisture in the material, cools and humidifies itself, and through the process of hot air dehumidification or condensation and water removal, the water in the material is discharged and taken away, and finally the material is dehumidified. Continuous drying, when many current dryers are drying the medicinal materials, due to the relatively single air outlet, the medicinal materials close to the heat source will be over-dried, and the medicinal materials far away from the heat source will be difficult to be fully dried, which will lead to the material frame.
