A dehumidification port 102 is opened at the bottom of the housing 1 for discharging moisture.

[0023] Please see Figure 2 , Figure 3 The serpentine diverter 6 is equipped with a fixed bracket 602 at one end away from the hot air duct 5. The other end of the fixed bracket 602 is fixedly installed to the inner wall of the housing 1. The hot air duct 5 is attached to one side of the outer wall of the housing 1. A pipe fixing clamp 501 is provided on the hot air duct 5. The hot air duct 5 is fixedly connected to the housing 1 through the pipe fixing clamp 501.

[0024] Please see Figure 2 , Figure 4The rotating shaft 8 is inserted into the housing 1 from top to bottom. A lever made of rubber is installed on the lower side of the stirring shaft 801. The lever extends into the material receiving area 701. When the motor 9 drives the rotating shaft 8 to rotate, the lever passing over the stirring shaft 801 can stir the plastic granules in the material receiving area 701, thereby allowing the plastic granules in the material receiving area 701 to be heated evenly and improving the drying efficiency. The rotating shaft 8 passes through the slot 702 at one end of the center of the drying tray 7, and the slot 702 opened on the drying tray 7 does not obstruct the rotation of the rotating shaft 8. One end of the serpentine diversion pipe 6 passes through the side wall of the housing 1 and is connected to the hot air pipe 5. A drying tray 7 is set below each serpentine diversion pipe 6. The air outlets 601 on the serpentine diversion pipe 6 facing the drying tray 7 are evenly distributed above the drying tray 7, ensuring that the hot air can fully contact the plastic granules on each layer of the drying tray 7, thereby improving the drying efficiency of the equipment for plastic granules.

[0025] The front of the housing 1 in this utility model is hinged with a door 2. A hot air furnace unit 3 is provided on one side of the housing 1.
