Abstract: A plurality of shucked shellfish are mechanically eviscerated utilizing a series of longitudinally aligned inclined channels, each channel formed of a power-driven roller and adjacent insert rollers, the insert rollers extending generally parallel and longitudinally aligned with each other. The frictional surfaces of the rollers and the spacing between adjacent rollers, or both, are controlled to effectively separate the soft shellfish viscerae from the soft adductor muscle of the shellfish without significant damage to the muscles.

Abstract: A plurality of shucked scallops are mechanically eviscerated utilizing a series of longitudinally aligned inclined channels, each channel formed of a bottom roller and adjacent side rollers, the side rollers extending generally parallel with and longitudinally coextensive with the bottom roller. The frictional surfaces of the rollers and the spacing between adjacent rollers, or both, are controlled to effectively separate the soft scallop viscerae from the soft adductor muscle of the scallops without significant damage to the muscles, that in such a manner as to be ineffective for the peeling of shrimp.
