Microwave drying will replace traditional drying in pharmaceutical industry
- May 07, 2019 -
< P > With the development of environmental protection industry, the drying industry of pharmaceutical industry is developing continuously, and the emergence of microwave equipment meets the requirement of drying medicinal materials appropriately, and also conforms to the current popular theme of environmental protection. P>Microwave drying equipment for Chinese medicinal materials can keep the active ingredients of Chinese medicinal materials to the greatest 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.
The society is developing constantly, and the renewal of drying equipment is the performance of the progress of pharmaceutical machinery industry. Enterprises should seize the opportunity of development on this basis and continuously promote the better development of the whole industry.
