The medicinal material dryer can be said to be a good embodiment of the microwave technology dryer in the market application. It perfectly shows the characteristics of the microwave technology, and also allows people to recognize and clearly realize the broad development prospects of microwave technology.
Microwave drying is different from traditional drying methods in that the direction of heat conduction is the same as the direction of moisture diffusion. 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, etc. Therefore, it is increasingly emphasized in various fields of drying.
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 dryer is to retain 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. This feature allows the material with poor heat conduction to be heated and dried in a short time, the energy utilization rate is improved, and the size of the heating furnace can also be made smaller than the conventional heating furnace. At the same time, when the material under the microwave electromagnetic field, the overall temperature of the material rises. At this point, due to evaporation of moisture on the surface of the material, the surface temperature decreases, resulting in a high temperature gradient inside and outside, the direction of this gradient just in line with the direction of moisture evaporation.
To achieve the modernization of traditional Chinese medicine production, it is necessary to scientifically and reasonably inherit traditional traditional Chinese medicine production techniques. At the same time, according to the characteristics of different traditional Chinese medicines, develop the most reasonable drying methods and techniques, give full play to the advantages of microwave drying, and promote the progress of traditional Chinese medicine industrialization.
