Microwave Drying Machinery Upgraded to the Backbone of Pharmaceutical Processing

- May 06, 2019 -

Different from the traditional drying method, the heat source is microwave generated by electric power through microwave generator. Microwave directly acts on the moisture in the molecule of the material. The heat generated by molecular oscillation makes the moisture evaporate, and then discharged outside the equipment through the dehumidification system of drying equipment. Microwave drying machine has the advantages of high drying rate, energy saving, high production efficiency, uniform drying, clean production, easy automation control and improvement of product quality. At the same time, it has the advantages of microwave sterilization and microwave sterilization while drying. Therefore, the emergence of microwave technology appropriately meets the current environmental protection theme.

microwave dryer can also kill all kinds of fungi and eggs in medicinal materials and 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.
