[0021] Furthermore, a stirring member is installed in the stirring and drying barrel 1, and the stirring member includes a rotating motor 4, a rotating rod 5 and multiple stirring rods 6. The rotating motor 4 is installed on the stirring and drying barrel 1, and the rotating rod 5 is rotatably placed in the stirring and drying barrel 1, and is threadedly connected to the rotating shaft of the rotating motor 4. Multiple stirring rods 6 are evenly connected to the rotating rod 5, and the rotating rod 5 and the multiple stirring rods 6 are both hollow and interconnected. The rotating rod 5 and the multiple stirring rods 6 are heat pipes, and heating elements 7 are installed in the rotating rod 5 and the multiple stirring rods 6.

A switch controller for switching the heating element 7 is installed in the rotating rod 5, and the switch controller is controlled by an external master control via a Bluetooth wireless connection. Specifically, an electromagnetic opening and closing door is installed at the joint between the stirring and drying barrel 1 and the hot air drying barrel 2. The TPU foamed particles are placed in a stirring and drying barrel 1, and a rotating motor 4 drives a rotating rod 5 to drive multiple stirring rods 6 for stirring. At the same time, a heating element 7 heats the rotating rod 5 and multiple stirring rods 6 to achieve heating while stirring, so that the TPU foamed particles are heated evenly. After drying, the particles are transferred to a hot air drying barrel 2.
