[0002] Dehydration is a crucial step in the production of plastic granules. During production, plastic granules are extruded into shape using an extruder, then cut into pellets by rotating blades. The pellets fall into a water circulation system and are flushed into a dewatering machine. Residual moisture remains on the surface of the plastic granules, necessitating dehydration and drying. However, the heating and dehydration process generates a large amount of water vapor, and current technology lacks corresponding exhaust devices, hindering its use.

A feeding trough is connected to the left side of the inner wall of the top of the dewatering cylinder, and a drive motor is fixedly installed in the middle of the top of the dewatering cylinder. This invention pours plastic granules into the dewatering cylinder through the feeding trough. The heating wire is controlled by a PLC controller to heat the plastic granules to a specified temperature for drying and dewatering. The drive motor is controlled to rotate, which drives the stirring rod to rotate, further uniformly stirring the plastic granules in the dewatering cylinder, improving the drying and dewatering efficiency. Since a large amount of water vapor is generated during the drying and dewatering process, the exhaust fan is controlled to work and exhaust the water vapor in the dewatering cylinder, improving the usage effect.
