Description of Industrial Belt Dryer
The raw material after washed should be distributed on the conveyer belt through suitable mechanism such as star distributor, swing conveyor, crusher or granulator, the conveyer passes through the channel including of one or several heating unit. Each heating unit is equipped with air heater and circle system. Each channel has one or several damp discharge systems. When the conveyer passes through it, hot air will pass through the raw material from up to down or from down to up. In this way the raw material can be dried uniformly.
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.
