The characteristics of the drum 2 are eliminated through the exhaust port 31, so the drum 2 is inclined, and the feeding end 21 of the drum 2 is higher than the discharging end 22, so that the reclaimed material can be easily affected by its gravity and be located opposite to each other. The discharge port 41 at the lower position discharges the material, and the hot air can be discharged from the exhaust port 31 through the inside of the drum 2. Therefore, the exhaust port 31 can be set at the top of the feed cover 3 in one embodiment; In addition, in the process of separately outputting the reclaimed material and the hot air, the driving device 5 rotates the drum 2 so that the reclaimed material and the hot air can be fully mixed, so that the efficiency of heat desorption and drying can be improved as described above; In one embodiment, the exhaust port 31 can be connected with an air pollution treatment system (not shown in the figure) to purify the air or water vapor discharged through the exhaust port 31 to reduce air pollution.

Regarding the configuration of the drum 2, in order to facilitate its assembly, installation and support, it can rotate smoothly. Therefore, in one embodiment, the two ends of the drum 2 extend through the heating chamber 1. The material cover 3 and the discharge cover 4 can also be located outside the heating chamber 1 to facilitate mutual assembly with the drum 2, and to prevent the heat energy in the heating chamber 1 from being connected to the drum 2 or the drum 2 separately from the inlet The connection between the material cover 3 and the discharging cover 4 leaks out and is lost. Therefore, the roller 2 is at the pivotal connection with the heating chamber 1, and the roller 2 is at the pivotal connection with the feed cover 3 and the discharge cover 4. A sealing component 6 is further provided in each place. In one embodiment, it can be a fish-scale sealing skirt to seal it and also be able to rotate, but it is only an example and not a limitation; In a preferred embodiment, due to the large volume of the roller 2, its weight is heavier to facilitate its support.
