PLC control microwave dryer common control mode:
Control microwave generator: PLC can control the switching state and power of the microwave generator, thereby controlling the intensity and stability of microwave radiation.
Control conveyor belt: PLC can control the conveyor belt in the microwave dryer, so as to realize the conveying and sorting of materials.
Control pneumatic system: PLC can control the pneumatic system in the microwave dryer, such as cylinders, valves, etc., so as to realize the control of the lifting and clamping force of the conveyor belt.
Monitor sensor signals: PLC can receive sensor signals in microwave dryers, such as temperature, humidity, material thickness and other information, and control accordingly according to this information.
Control hydraulic system: PLC can control the hydraulic system in the microwave dryer, such as oil pump, solenoid valve, etc., so as to control the clamping force, lifting height and other parameters.
Working principle of microwave dryer:
microwaves are first generated by the microwave generator when the equipment is running, and they are input into the microwave heater through the energy feeding device;
The material is sent to the heater by the transmission system, at which time the water in the material is heated and evaporated under the action of microwave energy, and the water vapor is removed by the dehumidification system to achieve the purpose of drying.
