Microwave vacuum drying technology combines the advantages of microwave technology and vacuum technology, the heat-sensitive material is extremely beneficial to the drying. Compared with conventional drying method, it has the characteristics of low energy consumption, short drying time, low working temperature, good product color and high vitamin retention rate. It is suitable for low temperature dry sterilization, low temperature concentration and sterilization of materials such as medicine, chemical industry, food, biological products, agricultural and sideline products, etc., which are heat sensitive, easily oxidized, highly viscous, for example: traditional Chinese medicine extract, ginseng, donkey hide gelatin, velvet antler, vegetables, flowers, biochemical products, health care products, additives, etc.
- Easy to control: Equipped with PLC automatic program control system, touch screen with human-computer interface, automatic monitoring of heating temperature, heating time, microwave density, with fault alarm system, can realize the simple operation of data storage.
- Energy efficiency: The microwave vacuum drying equipment adopts the radiant energy transfer, which is the whole heating of the medium, without other heat transfer medium, the drying speed is fast, the efficiency is high, and the energy consumption is reduced. Compared with the conventional drying technology, the work efficiency can be increased by more than four times.
- Extend shelf life: The biological effect of microwave energy can be sterilized and mildew proof at lower temperature. Because of its fast heating speed and short time, it can preserve the activity of the material, vitamins and the original color and nutrients.
- Environmental protection: Microwave vacuum equipment will not produce “three-wastes”, because the microwave energy is controlled in the heating chamber and the waveguide tube made of metal, the microwave leakage is very few, can be controlled at 2.0mw / cm2, no radioactive hazards and harmful gas emissions, no waste heat and dust pollution, neither pollution nor pollution of the environment.
