Microwave drying process for drying and sterilization of Chinese traditional medicine pills meets the national standard

- May 08, 2019 -

When drying Chinese medicine pills by microwave, the quality indexes of the finished Chinese medicine pills, such as properties, moisture content, dissolution time limit and microbial limit, all meet the national standards. It has been proved by many practices that microwave drying of traditional Chinese medicine pills not only has fast drying speed, good effect, superior sterilization performance, but also has high energy utilization rate. Microwave drying technology should be widely promoted in the drying production of traditional Chinese medicine pills. Microwave drying

is a method of drying materials by heating and evaporating water with microwave energy of 915-2450 MHz. Microwave drying is different from traditional drying, and its heat conduction direction is the same as that of water diffusion. Compared with traditional drying methods, it has the advantages of high drying rate, energy saving, high production efficiency, uniform drying, clean production, easy to realize automatic control and improve product quality. As a result, a great deal of research has been done on the application and theory of drying in various fields, and further development has been made in recent decades. Microwave has a non-thermal effect on organisms, which can be used to kill all kinds of microorganisms and achieve the purpose of sterilization. Compared with conventional thermal sterilization, microwave can obtain sterilization effect in a relatively low temperature and a relatively short time. Generally, the sterilization temperature can kill a large number of bacteria at 75 ~C. Microwave drying
