The invention relates to the technical field of new material processing, and discloses an engineering plastic cleaning and drying device based on the electromagnetic induction principle. The device comprises a first shell and a second shell, wherein a valve assembly is movably connected to the exterior of the first shell, a motor is movably connected to the exterior of the first shell, a rotatingshaft is movably connected to the exterior of the motor, a crawler belt is movably connected outside the rotating shaft, a partition plate is fixedly connected inside the first shell, and an insulating shell is fixedly connected inside the partition plate. Under the interaction of the first shell, the motor, the rotating shaft, the crawler belt, the partition plate, the insulating shell, a connecting rod, a copper rod, a conveying belt and an air outlet pipe, the stirring and cleaning functions can be auxiliary realized, a small amount of raw material can be intermittently subjected to solid-liquid separation, and then hot air drying is performed, so that the dryness of the raw material can be ensured to the maximum extent, the finished product bulging phenomenon caused by water residues is avoided, and the actual production requirement is better met.
