PVC Dehumidifying Dryer Equipment principle
The air from the blower becomes hot air through the heating tube, then controlled by the electronic temperature controller, and enters the hopper at an appropriate temperature to form an average air pressure. The hot air is drilled into the resin pellets and take away moisture, then exhaust through the air outlet.
The plastic pellets are continuously dried through the whole process of descending slowly from top to bottom, and its moisture is gradually reduced. After sufficient drying, the hot and dried resin material falls into the molding machine.Hot Air Hopper Dryer |
