A machine for segregating meat from bone, heavy tissue, and skin and having a material conveying screw mounted for rotation within a perforated conduit serving as a screen through which the meat is extruded as the bone, heavy tissue, and skin are conveyed toward the discharge end of the machine, is provided with a cutter ring with a cutting face against which the bone, heavy tissue, and skin are projected and cut before discharge. The conveying screw is preferably a cutter screw having a spiral flight which bears against the inside of the screen and contacts the margins of the perforations of the screen in a close cutting action as the screw rotates. Feeding cut meat and bone into the machine and operating the machine constitutes the method of the invention.
