The structure of the microwave sterilization dryer
Furnace cavity
It is a microwave resonant cavity, which is a space that converts microwave energy into heat energy to heat materials. In order to uniformly heat the materials in the furnace cavity, the industrial microwave oven is made into a tunnel style, and the materials run continuously on the conveyor belt.
Furnace door
The setting of the furnace door in the microwave sterilization dryer is mainly designed to facilitate the cleaning of the sanitation in the furnace cavity. In order to prevent the leakage of microwaves, the switch system of the industrial microwave oven consists of multiple safety interlock micro-switch devices. If the oven door is not closed properly, the industrial microwave oven cannot work, and if the microwave oven does not work, there is no problem of microwave leakage. In order to prevent microwave leakage from the gap between the oven door and the cavity after the door of the industrial microwave oven is closed, an anti-flow groove structure is installed around the oven door of the microwave oven, or a material that can absorb microwaves, such as silicone rubber The door seals made can absorb a small number of microwaves that may leak. The anti-flow groove is a special-shaped groove structure set in the door, which has the function of guiding the phase reversal of the microwave. At the entrance of the anti-sink, the microwaves are canceled by their counter-reflection waves, so that the microwaves do not leak.
The anti-flow groove structure is a stable and reliable method to prevent microwave leakage from the principle of microwave radiation. At present, a small number of companies adopt the most advanced anti-flow groove structure and production technology in the world, coupled with the newly developed multiple anti-microwave leakage technology, so that the microwave leakage control technology has reached the international advanced level.
Electrical circuit
It has the advantages of easy control, safety and stability, simple repair and maintenance, etc. It can adjust the power to meet the needs of different materials, and also save energy and be green.
Magnetron
The magnetron is the heart of the microwave sterilization dryer, which generates and emits microwave energy. Magnetron operation requires a high pulsating DC anode voltage and a cathode voltage of about 3 to 4V. The control work of the industrial microwave power supply provides the magnetron with a working voltage that meets the above requirements.
Timer
Microwave ovens generally have two timing methods, namely mechanical timing and computer timing. The basic function is to choose and set the working time. After the set time, the timer will automatically cut off the main circuit of the Microwave Sterilizing Machine.
Power divider
The power divider is used to adjust the average working time of the magnetron (that is, the ratio of "working" and "stop" time when the magnetron works intermittently), so as to achieve the purpose of adjusting the average output power of the Microwave Sterilizing Machine..
Interlock Micro Switch
Interlocking microswitches are an important set of safety devices for industrial microwave ovens. It has multiple interlocking functions, which are all controlled by the door opening button of the furnace door or the door opening button on the furnace door handle. When the oven door is not closed or the oven door is open, disconnect the circuit to stop the Microwave Sterilizing Machine..
Thermal breaker
A thermal cut-out is an element used to monitor the operating temperature of a magnetron or oven cavity. When the operating temperature exceeds a certain limit, the thermal circuit breaker will immediately cut off the power and make the microwave oven stop working.
