Abstract
A screening apparatus is provided for removing cartiledge, gristle and bone fragments from a ground moist product such as ground meat, the screening process comprising a form of extrusion between closely spaced helically corrugated revolving cylinders. The corrugations have sinusoidal contours with the contours of adjacent cylinders displaced 180 degrees from each other. The cylinders all revolve in the same direction so that spacing between the adjacent cylinders remains fixed and uniform while the advancing ridges of the corrugated surfaces move the retained cartiledge, gristle and bone fragments to one end of the cylinders to be exhausted from the apparatus.
