What are the components of a microwave dryer?
The magnetron is generating device of microwave. It provided by the power supply high voltage DC current and the input energy into microwave energy. The magnetron linear beam tube and cross field tube. A variety of food industry in a multi resonant cross field type magnetron tube.
The energy leakage suppressor is arranged at the material inlet and outlet of the heater, so as to prevent the electromagnetic wave in the resonant cavity from leaking out and injure the human body
The resonator, the heater, is a device that performs the interaction of microwave energy with the medium. The usual forms are case type, waveguide type, radiation type and surface waveguide type
Waveguide device is completed microwave transmission, interconnection, coupling and reversing transmission effect of microwave heating, often with long hollow metal tube section. Excitation and coupling effects of the waveguide device are required to set up the electromagnetic mode in the waveguide. Another non reversible transmission device is used for circulator connect the microwave source of the resonant cavity, when the resonant cavity for the material can not absorb all of the microwave power, part of the reflected power through the circulator into a terminal of the load, in order to protect
A microwave dryer consists of a power supply, a microwave tube, a connecting waveguide, a heater, and a cooling system
