Hopper Type Microwave Vacuum Composite Dehumidification Drying Device

At present, the drying treatment method of the extrusion and granulation of engineering plastic raw materials generally adopts a hot air drying hopper. The electric heating wire is blown by a hair dryer to spread the heat. Not only is it energy intensive, but it is also less efficient. Another drying method uses the honeycomb spinning molecular sieve drying principle. The main disadvantage is that the molecular sieve regeneration process consumes a lot of energy. At the same
