Abstract: microwave drying equipment, vacuum freeze drying technology, low temperature adsorption drying technology, heat pump drying technology and spray drying technology are introduced. The combined drying technology can realize the high efficiency and energy saving of the drying process of the medicinal materials, which is the trend of drying area.
Key words: drying equipment; microwave drying of traditional Chinese medicine; vacuum drying
Drying is an indispensable link in the processing and production of Chinese medicinal materials. The drying process directly affects the quality of Chinese medicinal products. In the drying process, time and temperature are important parameters. The magnitude of their magnitude is closely related to the loss of effective components and the degree of inferiority. Therefore, the selection of drying equipment types and the setting of control conditions are particularly important for the production and processing of Chinese medicinal materials.
