ABSTRACT:
A self-cleaning centrifugal dryer system and method for removing surface moisture allow complete removal of plastic pellets, flakes and particles from the dryer and water-conveying or water processing system during or after each drying cycle. By eliminating plastic particulate retention in the dryer and throughout the water conveyance and processing systems whereby contamination of different type materials dried during a subsequent drying cycle is avoided. Air and water alone or in combination under pressure are discharged toward various accumulation or occlusion (“hang-up”) points in the dryer and throughout the water-conveying or processing system to remove retained plastic pellets, flakes and particles.
