The microwave dryer is different from the traditional drying method in that the heat conduction direction is the same as the moisture diffusion direction. Compared with the traditional drying method, it has the advantages of large drying rate, energy saving, high production efficiency, uniform drying, clean production, easy realization of automatic control and improvement of product quality. At the same time, it also has the advantages of killing, sterilization and other characteristics, so it is favored by customers.
The traditional medicinal material drying machine is designed to use coal as fuel for combustion to generate clean hot air as a drying medium to absorb the moisture in the Chinese medicine, drain out the moist air that reaches a certain amount of moisture, and circulate back and forth to reach the moisture required by the traditional Chinese medicine. The characteristics are time-consuming, laborious, unable to fully meet the requirements for medicinal drying, and poor sterilizing properties, coupled with the use of coal as fuel to pollute the environment. Therefore, the emergence of new process technology becomes extremely necessary. The appearance of microwave technology satisfactorily met the requirements for drying and drying medicinal herbs, and coincided with the prevailing theme of environmental protection.
The microwave medicine drying machine retains the effective drug ingredients in the Chinese herbal medicine to the utmost extent. Microwaves can also kill various molds and eggs in herbs to prevent mildew and insects from being produced during storage. All this is because: Microwave heating is to make the object to be heated itself a heating element, called the overall heating method, does not require the process of heat conduction, so it can reach uniform heating in a short time.
