Attention problems in drying process of traditional Chinese medicine

Introduction of traditional Chinese medicine heat pump dryer: Traditional Chinese Medicine heat pump dryer is a new type of high-efficiency and energy-saving drying equipment. Its working principle is based on the reverse Carnot cycle principle, using a small amount of electric energy and utilizing the compressor to absorb a large amount of heat energy in the air, after the working medium passes through the expansion valve, it evaporates into gas in the evaporator, then compresses the gas medium into high temperature and high pressure gas through the compressor, and then enters the condenser to release heat and heat the drying medium, such constant cyclic heating. Compared with the electric dryer, it saves 2/3 of the electric energy. Let's take a look at the things that should be paid attention to when drying Chinese herbal medicines: 1. Chinese herbal medicines cannot be dried at too high a temperature. If the temperature is too high, the contents of Chinese herbal medicines will volatilize, which will lead to the loss of drug quality. 2. The moisture removal should not be too fast, otherwise it will affect the drying quality of the medicinal materials. 3. The temperature control is carried out in sections, and the higher the temperature, the lower the temperature. If you have any questions, please contact us for a more detailed explanation, hoping to provide you with a better analysis of drying technology.
