The hot air circulation system mainly includes a cyclone separator, a blower, an air filter, and a heater. The hot air from the dryer is removed by the cyclone separator and returned to the blower. After filtering, it can be heated and sent to the dryer. During the cycle, part of the circulating air is continuously discharged according to the humidity of the air. After the fresh air after dehumidification filtration, the drying effect is better.
Most of the hot air circulates in the tank, which is highly efficient and saves energy. The utility model utilizes the forced ventilation function, and the adjustable air distribution plate is arranged in the box, the material is evenly dried, and the heat source can be steam, hot water, electricity and far infrared, and the selection is wide. The whole machine has a small voice and balanced operation. Temperature control, easy installation and maintenance. Wide range of applications, can dry a variety of materials, is a general drying equipment.
