Abstract: In a preferred embodiment, for a method of extracting crab meat from the under-shell once the top shell is removed and after washing, the meat-containing under-shell is fed into the bite of pincher rolls after first adjusting the parallel axes of the pincher rolls to an angle of about 75 degrees as measured from a horizontal, and as the meat is thereby squeezed-out in a direction forward of the pincher rolls and slides downwardly, the extracted meat is collected by use of a converging guide member beneath the bite position at a base of the pincher rolls guiding the meat to a collection vessel, the pincher rolls being supported on a support structure with one roll pivoted toward the other and held in a predetermined position such that the meat-containing crab-shell is compressible therebetween and dragged through the bite behind which the debris-residual meatless shell is permitted to fall away into a trash-collecting vessel, the opposing rolls revolving surfaces each being cleaned by a counter-revolving brush
