Abstract: An improved apparatus and method for eviscerating scallops and other shellfish is provided which includes a cylindrical drum having side walls formed from a plurality of rollers mounted between a pair of rims which define the longitudinal ends of the drum. A drive mechanism is provided for rotating adjacent rollers to rotate in opposite directions. Each of the rollers has a frictional surface to allow adjacent rollers to grip the viscera and pull it from the edible muscle as the rollers are rotated. A drive mechanism is also provided for rotating the drum about its longitudinal axis. To divide the drum into a plurality of sections to ensure sufficient contact of the scallops being cleaned with the viscera removing rollers and to allow the capacity of the drum to be maximized, radial plates are mounted within the drum and are rotated with it.
