The working principle and application range of medicinal herb drying machine

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

The medicinal herb dryer is equipped with coal as fuel for combustion, generating clean hot air as the drying medium to absorb the moisture inside the traditional Chinese medicine, expel the moist air that has reached a certain moisture content, and circulate back and forth to achieve the required moisture content for the traditional Chinese medicine. This device is simple, convenient, with low investment and effectiveness

Okay, with low operating costs, it is the preferred drying equipment for traditional Chinese medicine and food processing enterprises. This device can meet the requirements of room temperature and variable temperature drying for various traditional Chinese medicines, with containerized drying equipment and tunnel drying equipment available.

operational principle

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 external air, or to recover the waste heat from the exhaust during the drying process. After the compressor does work, the energy is transported (transferred) to the drying box, and the hot air inside the drying box

After repeated cycles of heating, absorbing moisture from the material, self cooling and humidifying, and through the process of hot air dehumidification or condensation to remove water, the water in the material is discharged and taken away, ultimately achieving continuous drying of the material, with a maximum output temperature of 85 ℃.

Scope of application

This drying oven is mainly suitable for drying, heating, and heat treatment of product test samples in industrial and agricultural production, scientific research, medical and health, laboratories, and other units. The temperature of this drying oven can be adjusted from 10 ℃ to 300 ℃, and the selected working temperature can be automatically controlled by the temperature control system inside the oven. Adopting a digital temperature controller, it is sensitive, reliable, easy to operate, and the digital display is more intuitive and clear. It is used as a laboratory in research departments such as colleges, medical and health, and environmental protection, as well as in industrial, mining, and agricultural experiments or production lines. This machine is equipped with an air blowing device, and the air enters the studio through the air duct, promoting the circulation and convection of hot air in the studio, thereby achieving better temperature uniformity.
