[0035] Working Principle: During use, place the plastic granules to be dried evenly on multiple trays 6 and close the drying chamber 1. Set the drying program via the control panel 13 and start the heater 3 and blower 2. Blower 2 draws in outside air and discharges it into heater 3. The heating wire in heater 3 heats the flowing air, creating hot air that passes through the guide shroud 4 into the drying chamber 1 to dry the plastic granules. Temperature and humidity sensors monitor the temperature and humidity inside the drying chamber 1 in real time and transmit the data to the PLC controller on the control panel 13. When the temperature is too high or too low, the PLC controller adjusts the power of the electric heating element; when the humidity reaches a certain value, the PLC controller controls blower 2 to increase the airflow, expelling moisture from the exhaust pipe 14 while introducing fresh air. After drying is complete, the PLC controller stops blower 2 and heater 3. Once the light strip temperature drops, the operator can remove the trays 6.

[0036] In summary, compared with the prior art, this application, by setting up a blower 2 and a heater 3, draws airflow through the heater 3, which heats the air. The heated air is then blown into the drying chamber 1 through the guide shroud 4 and the air distribution plate 12, thus facilitating the drying of the plastic granules inside the tray 6. Furthermore, the drive cylinder 7 is connected to the placement rack 5, which drives the placement rack 5 to move back and forth rapidly, causing the placement rack 5 to shake. This shakes and changes the position of the plastic granules inside the tray 6, avoiding the drawback of uneven drying of the plastic granules inside the tray 6 and facilitating the rapid and effective uniform drying of the plastic granules inside the tray 6.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
