Microwave Equipment Promotes the Modernization of Pharmaceutical Production in China

- May 07, 2019 -

At present, microwave equipment has been put into use in most pharmaceutical enterprises in China, which makes the regional automation and modernization of Chinese medicinal materials production. Microwave drying is different from traditional drying, and its heat conduction direction is the same as that of water diffusion. Compared with traditional drying methods, it has many advantages, such as high drying rate, energy saving, high production efficiency, uniform drying, clean production, easy to realize automatic control and improve product quality. Therefore, more and more attention has been paid to drying in various fields.

The traditional medicine dryer uses coal as fuel to burn and generates clean hot air as drying medium to absorb moisture in traditional Chinese medicine, remove humid air that reaches a certain moisture content, and circulate to and fro 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 appropriately meets the drying requirements of medicinal materials, and also conforms to 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, known as the overall heating mode, does not need the process of heat conduction, 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, which results in a temperature gradient of high inside and low outside, the direction of which coincides with the direction of water evaporation. 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.
