Microwave drying machine is different from the traditional drying method, the direction of heat transfer and moisture diffusion direction of the same.Compared with the traditional drying method, with the drying rate, energy saving, high production efficiency, dry uniform, clean production, easy to achieve automatic control and improve product quality and so on. At the same time, also both the fixing, sterilization and other characteristics of advantages!
Medicine microwave dryer can be said that the microwave technology dryer in the market application of a good embodiment of the perfect display of the characteristics of microwave technology features, but also let people know and clearly aware of the broad prospects for the development of microwave technology.
The traditional medicine drying machine is made of coal for fuel combustion, and the clean hot air is used as the drying medium to absorb the moisture in the traditional Chinese medicine, and the wet air reaches the certain moisture, and the circulation is required to reach the moisture demanded by the traditional Chinese medicine. Characterized by time-consuming, laborious, can not fully meet the requirements of medicine drying, while poor sterilization, coupled with coal as fuel pollution of the environment. Therefore, the emergence of new technology seems to be unnecessary. The emergence of microwave technology, appropriately meet the requirements of dry and dry medicine, and now popular fashion theme.
Microwave medicine dryer in the maximum retention of Chinese herbal medicine in the effective ingredients. Microwave can also kill a variety of herbs in the mold and eggs, to prevent the storage process of mildew and insects. All this is because: microwave heating is to make the object itself to be heated body, called the overall heating method, do not need heat conduction process, so in a short time to achieve uniform heating. This feature allows the heat conduction of poor material in a short period of time to be heated and dry, the energy utilization rate is improved, but also can make the size of the furnace than the conventional heating furnace is smaller. At the same time, when the material in the microwave electromagnetic field effect, the overall material temperature rise. At this point, due to evaporation of water on the surface of the material, resulting in reduced surface temperature; resulting in a high outside the low temperature gradient, the direction of the gradient just coincides with the direction of evaporation of water. So, the efficiency is high, the effect is good!
With the recent trend of the rapid spread of Chinese medicine, microwave drying equipment will be more and more widely. China should strengthen the microwave drying equipment development and production level, and constantly to the internationalization.
