ABSTRACT:
In known processes and known apparatus for mechanical separation of a combination of meat and bone into useful fractions, the combination is conveyed as by a screw through a screen, which constitutes a portion of an elongated cylindrical conduit, and softer components are expressed through the screen, while harder components are contained by the screen. As such processes and such apparatus have been improved, softer components are expressed outwardly through a plurality of arcuate slots respectively defined on two sides by flexible walls of the screen, major amounts of harder components are contained by the screen, the walls flex to allow minor amounts of harder components to be expressed outwardly through the slots if too small to be effectively contained by the screen without consequent blockage of the screen, such flexing of the walls is limited by an integral spacing element extending across each slot from one wall, and any sinews tending to become ensnared around the element are presented to sharp corners provided on the element and designed to cut such sinews.
