1. The working principle of industrial microwave oven
A microwave is a kind of high-frequency wave with a speed change of 2.4 billion times per second, causing a high-speed pendulum movement of water molecules. They rub against each other to produce significant heat, which can be convenient for drying materials.
After the object absorbs microwave energy into heat, the object temperature rises, the moisture in the object evaporates, dehydrates, and dries. If the dehydration rate is properly controlled, the structure of the thing can be loosened and puffed up when drying the material. In this process, the heating temperature can also be controlled to adjust upwards so that the object is baking.
(1) Furnace cavity. The furnace cavity is a microwave resonance cavity, which is the microwave energy into thermal energy to heat the space of the material. In order to make the material in the furnace cavity evenly heated, industrial microwave ovens are made into a tunnel type, with the material running continuously on a conveyor belt.
(2) Door. The door is designed to facilitate the cleaning of the oven cavity in an industrial microwave oven. The microwave oven's switching system consists of multiple safety interlocking micro switches to prevent leakage of microwaves.
(3) Electrical circuits. The electrical circuit is divided into three parts: the low-voltage circuit, the control circuit, and the high-voltage circuit. The circuit after the secondary winding of the high-voltage transformer is the high-voltage circuit, which mainly includes magnetron, high-voltage capacitor, high-voltage transformer, and high-voltage diode.
(4) Magnetron. The magnetron is the heart of the microwave oven, from which microwave energy is generated and emitted. The magnetron requires a very high pulsating DC anode voltage and a cathode voltage of about 3 to 4V to operate. The high voltage transformer, high voltage capacitor, and high voltage diode from a multiplier rectifier circuit provide the magnetron with the working voltage to meet these requirements.
The circuit between the primary winding of the high-voltage transformer and the power inlet of the industrial microwave oven is a low-voltage circuit (which also includes the control circuit), consisting mainly of fuses, thermal circuit breakers, protective switches, interlocking micro switches, lighting, timer, and power divider switches, conveyor motors, fan motors, etc.
(5) Timer. Microwave ovens generally have two types of a timer, namely mechanical timer and computer timer. The primary function is to select the set working time, and after the set time, the timer automatically cuts off the primary circuit of the microwave oven.
(6) Power divider. The power divider is used to adjust the average working time of the magnetron (i.e., when the magnetron is working intermittently, the ratio of "working" and "stopping" time) to achieve the purpose of adjusting the average output power of the microwave oven.
(7) Interlocking microswitches. The interlock micro switch is an important safety device for industrial microwave ovens. It has multiple interlocks, all controlled by the door open button or the door open button on the door handle. When the door is not closed, or the door is available, the circuit is broken, and the microwave oven stops working.
(8) Thermal circuit breaker. The thermal circuit breaker is a component used to monitor the operating temperature of the magnetron or oven cavity. When the operating temperature exceeds a specific limit, the thermal breaker will immediately cut off the power supply and stop the microwave oven from working.
This industrial microwave oven in the design of the above principles and the processing or production is also significant progress. This design also has the advantage of energy-saving and environmental protection, and in the production of the environment also has a certain improvement, people with the same thing is, of course, inseparable from the topic of money, in terms of cost, the cost of industrial microwave oven is relatively low, so, everyone in the use of this microwave oven Also pays attention to the pollution before or after the use of corruption to keep it clean and hygienic.

3. Why are industrial microwave ovens essential?
At the heart of a microwave oven is a magnetron tube. The tube is a microwave generator that produces microwaves that vibrate 450 million times per second. The microwaves, invisible to the naked eye, can penetrate food up to 5 cm deep, causing the water molecules in the food to move with it, generating a large amount of heat in the violent movement, so the food is 'cooked.' Industrial microwave systems are fast and efficient.
4. Technical advantages of industrial microwave ovens
Short time and high efficiency. Microwave heating is to make the object heated into a heating body without the need for a heat transfer process. The microwave penetrates the inside of the object from all sides. It is heated inside and outside simultaneously so that the object reaches uniform heating in a very short time, significantly reducing the drying time.
Easy to control, advanced technology. Compared with conventional drying methods, the equipment is ready to use. There is no thermal inertia, flexible and convenient operation; microwave power is adjustable, the transmission rate is adjustable. In microwave heating and drying, no waste gas is produced, which is harmless high-tech equipment.
