Abstract

PROBLEM TO BE SOLVED: To efficiently carry out washing and dehydration treatment of small pieces of recovered paper cup, milk carton, or the like, and a series of recycling treatments. SOLUTION: This washing dehydrator 4 is obtained by successively and concentrically fitting a dehydration tank 40, a washing tank 50 and a guide cylinder 60 at fixed intervals, respectively, to an outer wall tank 20 arranged on a frame 31. Small pieces crushed into a proper size by a crushing machine 3 are fed together with washing water from a basket 61 to the guide cylinder 60, dropped in the cylinder 60 while being washed with the washing water and released from an outlet opening 52 at the lower part of the washing tank 50 by centrifugal force of the washing tank into the dehydration tank 40. The washing water attached to the surfaces of the small pieces in the dehydration tank is removed by the high-speed rotation of the washing tank and the small pieces are sent to an upper pneumatic transportation chamber 23 by a spiral screw 53 attached to the outer periphery of the washing tank 50 and transported from an outlet opening 24 by an air flow of a blower 70 to a cyclone 72 outside the dehydrator 4.
