Apparatus for eviscerating fresh scallops immediately after they have been shucked from the shell, which apparatus cleanly strips membrane, roe and entrails from the edible adductor muscle without causing damage to the latter. No ageing, chemical or heat pretreatment is required. The apparatus includes a feed hopper which meters product flow single file onto one end of a set of two horizontal, counterrotating pinch rollers. A horizontal open bottom trough directs and contains the scallops on the top surfaces of the rollers. The rollers are critically sized and knurl textured and supported in rolling contact so as to nip and downwardly strip off soft entrails and membrane but support the firm cylindrical meat (muscle tissue). Water sprays and high speed cylindrical rotary brushes clean the rollers from below. The rollers have left and right hand helical grooves which advance the product along the rollers from the hopper to a discharge end while being processed. The knurl patterns of the rollers preferably have a plurality of longitudinal V-shaped grooves cut into them for about the first 6 to 10 inches of the rollers to damage the roe and liver which are then more readily caught in the nip between the rollers.
Apparatus for eviscerating scallops after they have been shucked comprising an elongated generally horizontally extending trough portion for receiving said scallops, said trough portion having a bottom slot, and comprising first and second elongated rolls disposed in side-by-side relationship in said bottom slot, said rolls defining a nip in a vertical plane between said rolls, said first roll having a knurled surface and being provided with a left-hand-thread helical groove, said second roll having a knurled surface and being provided with a right-hand-thread helical groove, said apparatus having means for rotating said rolls in opposite directions so that their surfaces enter said nip in a vertically downward direction whereby viscera tend to be pulled from muscle portions of the scallops and through said nip while said grooves move the scallops longitudinally along the rolls toward a discharge region, said apparatus having rotary cleaning brushes engaging said rolls below said slot and said brushes engaging flicker bars to clean the brushes.
