How to Construct Industrial Microwave Dryer Equipment

- May 08, 2019 -

< P > The research of microwave energy application began in 1970s in China, and the research of microwave dryer application technology and the development of magnetron for microwave heating began in 1973. In 1974 and 1980, the Ministry of Electronic Industry held the "National Microwave Energy Promotion and Application Technology Exchange" to exchange microwave academic and application technology issues. In March 1981, with the approval of the Ministry of Machinery and Machinery, a microwave energy popularization and application station of China Electronic Device Industry Corporation was established, which is responsible for the organization, design and research of microwave energy popularization and application in China. In October 1983, the Chinese Society of Electronics held the first National Academic Exchange on Microwave Energy Applications. Subsequently, every two years, microwave application technology exchanges will be held alternately in selected areas with good promotion and application throughout the country, in order to promote the development of microwave industry in China. Each session has a collection of papers published, involving industrial, agricultural, pharmaceutical, scientific research and other fields of application. The main structure of industrial microwave drying equipment:

P>P>1. Microwave cavity: that is, the internal space of microwave equipment, materials are heated, dried or sterilized in the microwave cavity;

2, microwave generator: commonly known as magnetron, which converts electric energy into microwave energy;

3, waveguide: microwave generated by microwave generator enters the microwave cavity through the waveguide excitation cavity, and then enters the microwave cavity. The function is to take the microwave energy out of the required mode through the excitation of the waveguide to the carrier which needs to be heated, dried and sterilized;

P>4, the suppression part: such as microwave oven door, suppressor and other restraining mechanism, to prevent and control microwave leakage to meet the requirements of the national standard;

5, conveying material mechanism: refers to the conveying mechanism such as track or conveyor belt.

6. Dehumidification and heat exhaustion mechanism: Exhaust steam from microwave cabinet and electrothermal gas from power supply cabinet to solve the problem of overheating in microwave cabinet. Measuring system: For example, measuring temperature of materials and humidity of drying room, these measuring data are displayed directly by instrument.

8, automatic control system and operation interface: This part mainly includes (PLC) programmable controller and touch screen. The programmable controller receives the measurement data and the relevant signals of each part of the equipment, and receives the control of the operator, so as to control the operation of the whole equipment, set various process parameters and display the relevant state in the working process through the touch screen.

9. Other parts such as electric drive part, cooling mechanism, safety protection and sound-light alarm, and other supporting parts can be set as required.

Microwave technology has been applied in more and more fields. The structure, power allocation and affiliates of industrial microwave equipment are determined according to the specific production process. Henan Microwave Equipment Co., Ltd. has made the world's leading industrial microwave industry enterprises the first to launch super-large and high-power microwave production equipment, pioneering the entry of industrial microwave into large-scale production enterprises. It is a revolutionary leap in drying, sintering and other process production. It saves more than 50% energy. It is pollution-free and energy-saving. It is the first choice of energy-saving alternative equipment in high-polluting industries, especially in medicine, chemical industry, ceramics, refractories and other industries. The company will design and produce suitable equipment according to the actual situation of customers to ensure that our equipment meets the production process requirements of manufacturers.
