The appearance of microwave vacuum dryer marks a new process of industrial microwave civilianization.

Commercial microwave vacuum dryer reduces the cost of microwave vacuum drying equipment and makes a practical microwave vacuum dryer. Work process: Microwave device selectively heating water in clothes, vacuum device to create a negative pressure environment, so that the boiling point of water can be reduced while quickly removing steam, thereby reducing the temperature of dry clothes, dry clothes completed, automatic shutdown.

Microwave Vacuum Dryer Detailed Introduction: Let users use cheap, power-saving, quiet dryer. Absorption rate of water to microwave in clothes is 95% and that of clothing fibers is 5%. A negative pressure environment is created by using microwave device to heat water in clothes with high selectivity. The water is changed into steam at lower temperature. The vacuum device expels water vapor quickly, prevents high temperature steam from conducting heat to low temperature clothing fibers, reduces drying temperature and improves drying temperature. Drying speed.

Microwave vacuum dryer is near the end of drying clothes. Microwave energy is absorbed by clothing fibers, and the temperature on the surface of clothes rises rapidly. Infrared temperature sensor detects this state and ends the drying process under the control of automatic control device. In the microwave vacuum drying process, before the moisture content of the material is reduced to 10%, the increase of the material temperature is mainly caused by the heat transfer from water vapor to the material. The rapid discharge of water vapor plays an important role in reducing the material temperature and improving the drying speed in the drying process. Near the end of drying, the moisture content of materials is less than 10%. The temperature rise of materials is mainly caused by the absorption of microwave energy. Monitoring the temperature of materials and stopping heating quickly play an important role in controlling the drying end point temperature.

The applicability of the theory to porous materials with high moisture content of clothing was verified by the microwave vacuum dryer prototype. According to the proposed theory, a prototype is designed and manufactured. The prototype is composed of microwave device and vacuum device. The pressure-resisting container is eliminated. The low-cost and large-volume vacuum device is used to produce rough vacuum, which greatly reduces the cost and mechanical noise during operation. Infrared temperature sensor is used to monitor the surface temperature of materials, and combined with automatic control device, the drying degree and drying temperature of clothes are controlled. The advent of
