Main structural characteristics of industrial microwave drying equipment

With the gradual rationalization and maturity of the market, the technical update of microwave drying equipment has become increasingly important. Excellent microwave equipment manufacturers can't just rely on imitating peer equipment to develop, but to continue to innovate. The traditional air-cooled microwave electronic circuit has poor stability, and is often susceptible to electrical high-voltage breakdown damage in industrialized humid, dusty and corrosive environments, resulting in a large amount of equipment maintenance devices, which brings economic and production losses to the user. The new industrial microwave drying equipment is a drying device that uses microwave high-frequency oscillation energy to be directly absorbed by moisture into a form of heat energy vapor release. In the 1990s, it has made certain contributions to the low-temperature drying in the fields of food, Chinese patent medicine, chemical industry and ore industry.

Main structure of industrial microwave drying equipment

1. Microwave cavity: the internal space of the industrial microwave drying equipment, the material is heated and dried or sterilized in the microwave cavity;

2, the suppression part: such as microwave oven doors, suppressors and other suppression mechanisms to prevent and control microwave leakage to meet the national standard requirements;

3. Waveguide: The microwave emitted by the microwave generating source enters the microwave cavity through the waveguide excitation cavity, and its function is to take the energy of the microwave through the excitation mode of the waveguide to the carrier that needs heat drying and sterilization;

4. Drainage and heat removal mechanism: discharge the steam in the microwave box and the electric heating gas in the power box to solve the problem of overheating and overheating in the microwave box.

5. Material conveying mechanism: refers to the conveying mechanism such as rail or conveyor belt.

6, microwave source: commonly known as magnetron, it converts electrical energy into microwave energy;

7. Measurement system: If the temperature of the material and the humidity in the drying chamber are measured, these measurement data are directly displayed through the meter.

8. Automatic control system and operation interface: This part mainly includes programmable controller and touch screen. The programmable controller receives the measurement data and related signals of each part of the device, and accepts the control of the operator, thereby controlling the operation of the entire device, setting various process parameters through the touch screen and displaying the relevant state in the working process.

9. Others: such as electric drive part, cooling mechanism, safety protection and sound and light alarm, other supporting parts, etc. can be set as required. The application fields of microwave technology are constantly expanding. The structural form, power configuration and subsidiary mechanism of industrial microwave equipment are determined according to the specific production process.
