Microwave Drying Promotes the Development of Traditional Chinese Medicine in China

- May 08, 2019 -

< P > Henan Microwave Equipment Network News: The rapid development of Western medicine abroad has brought a certain impact on the development of Chinese traditional medicine. Because of the imperfection of pharmaceutical equipment, the production of traditional Chinese medicine is restricted by the external environment. Microwave drying equipment is a new drying method. Compared with the traditional drying method, the drying speed is faster and energy-saving. Microwave drying is different from traditional drying, and its direction of heat conduction is the same as that of water diffusion. The traditional medicine dryer uses coal as fuel to burn and produces clean hot air as drying medium to absorb moisture in traditional Chinese medicine, discharges humid air which reaches a certain moisture content, and reciprocates to meet the moisture requirement of traditional Chinese medicine. It is characterized by time-consuming, laborious, incomplete drying requirements of medicinal materials, poor sterility, and pollution of the environment with coal as fuel. Therefore, the emergence of new technology is very necessary. The emergence of microwave technology is appropriately satisfied. In order to realize the modernization of traditional Chinese medicine production, we must inherit the traditional Chinese medicine production technology scientifically and reasonably, and develop the most reasonable drying method and process according to the characteristics of different traditional Chinese medicine, give full play to the advantages of microwave drying, and promote the progress of industrialization of traditional Chinese medicine. The requirements of drying and drying of medicinal materials are in line with the current popular theme of environmental protection.

P>Microwave dryer for Chinese medicinal materials retains the active ingredients of Chinese medicinal materials to the maximum extent. Microwave can also kill all kinds of fungi and eggs in medicinal materials to prevent mildew and moth during storage. All this is because: microwave heating is to make the heated object itself become a heating body, called the overall heating mode, without the need for heat conduction process, so it can achieve uniform heating in a short time. This feature can make the materials with poor heat conduction heated and dried in a short time, improve the utilization rate of energy, and also make the size of heating furnace smaller than that of conventional heating furnace. At the same time, when the material is under the action of microwave electromagnetic field, the overall temperature of the material rises. At this time, due to the evaporation of water on the surface of the material, the surface temperature decreases, resulting in a temperature gradient of high inside and low outside, the direction of which coincides with the direction of water evaporation.
