A device that can be inserted in an ordianry sink drain and disintegrate trapped debris by rotary motion of a rotor blade. Debris in flowing drainage is trapped in perforations of a receptacle cylinder. The rotor blade which is mounted centrally within a receptacle cylinder is actuated by linear strokes of a steeply pitched threaded rod passing through the threaded bore of the rotor. The upper part of the threaded rod includes a finger grip and a perforated cap piece with a mated and perforated gate cap which may function as an upper strainer obstacle when fitted within the main cylinder of the sink drain. When the cap is closed and moved within the drain main cylinder, it can impart a final compressive force downward.
