The medicinal herb dryer uses a heat pump evaporator to absorb heat from the air to dry medicinal herbs, and is widely used in agricultural production, scientific research, and medical health.

The medicinal herb dryer is equipped with coal as fuel for combustion, generating clean hot air as the drying medium to absorb the moisture in the medicinal herbs and discharge the moist air that reaches a certain level of moisture. It circulates back and forth to achieve the required moisture level for the medicinal herbs. This equipment is simple, convenient, requires minimal investment, has good results, and has low operating costs. It is the first choice for drying equipment in traditional Chinese medicine and food processing enterprises. This device can meet the requirements of various traditional Chinese medicines for room temperature and variable temperature drying, including containerized drying equipment and tunnel drying equipment.

The main principle of using a medicinal herb dryer in the drying process is to use a heat pump evaporator to absorb heat from the outside air, or to recover the waste heat from the exhaust during the drying process. The energy is then transferred (transferred) to the drying box through a compressor, and the hot air inside the drying box is repeatedly circulated and heated to absorb moisture from the material, cooling and humidifying itself. Through the process of hot air dehumidification or condensation dehumidification, the water in the material is discharged and carried away, finally achieving continuous drying of the material with a high output temperature of 85 ℃.
