Abstract: An apparatus for mechanically rinsing and scraping bi-valve mollusks and the like. The mollusks are placed into a perforated drum that is rotated by a motor, the drum having a plurality of agitation protrusions for churning, lifting and dropping the mollusks so they become frictionally engaged with one another and the plurality of abrasive elements contained therein thereby effectively scraping off any barnacles or other like debris. Jet streams of water are emitted to shower the mollusks during operation and a housing assembly that maintains the perforated drum therein also forms a basin that retains the effluence and creates an agitating, churning bath to facilitate cleaning. The front panel of the housing assembly is hinged to a bottom plate thereof and has two perpendicular side panels extending therefrom to form a chute for unloading the mollusks in an orderly manner into a bucket or other like container.
