Vacuum Belt Type Microwave Dryer

Description:

● Heat source (for example, low pressure steam or thermal conduct oil) passthrough the sealed jacket. The heat will be transmitted to raw material to bedried through inner shell;
● Under driving of power, the tank is rotated slowly and the raw material inside itis mixed continuously. The purpose of reinforced drying can be realized;
● The raw material exists is under vacuum. The drop of steam pressure makesthe moisture (solvent) at the surface of raw material become saturation and willevaporate. The solvent will be discharged through vacuum pump an recoveredin time. The inner moisture (solvent) of raw material will infiltrate, evaporate anddischarge continuously. The three processes are carried out unceasingly andthe purpose of drying can be realized within a short time.

How it works?

When the equipment running, the microwave is first generated by the microwave generator, and the feeding device is input into the microwave heater; the material is sent to the microwave heating chamber by the transmission system, and the moisture in the material is heated and evaporated under the action of the microwave energy, and the water vapor passes. The dehumidification system is eliminated to achieve the purpose of drying. The bacteria in the material are killed by the biological and thermal effects produced by the microwave electromagnetic field. Since the microwave acts directly on the material, the drying temperature is low and the speed is fast, and the loss of the active ingredient in the material is small.
