With the acceleration of the development of production in modern society, the development of food and other industries is also accelerating. In the food industry, the drying of products is a crucial step to ensure that medicinal materials are not eaten and corroded by insects. In recent years, due to the great superiority of microwave drying technology, the demand for microwave drying equipment in the traditional Chinese medicine industry is also increasing.
The traditional dryer equipment uses coal as fuel to burn to generate clean hot air as a drying medium to absorb the moisture of the product, discharge the moist air that reaches a certain moisture, and reciprocate to achieve the moisture required by traditional Chinese medicine. It is characterized by time-consuming, laborious, can not fully meet the requirements of food drying, and at the same time has poor sterilization, coupled with the use of coal as fuel to pollute the environment.
In recent years, with the continuous advancement of the environmental protection industry, the emergence of new microwave drying and sterilization technology is very necessary. The emergence of microwave drying technology appropriately meets the requirements of food, chemical industry, agricultural products, drying and sterilization, and is in line with the current popular theme of environmental protection.
According to experts, microwave drying is different from the traditional drying method, and its heat conduction direction is the same as the direction of moisture diffusion. Compared with the traditional drying method, microwave drying sterilization has the advantages of large drying rate, energy saving, high production efficiency, uniform drying, clean production, easy to realize automatic control and improve product quality, so it has attracted more and more attention in various fields of drying and sterilization.
