Abstract

A conventional meat grinder contains a chopper knife and a chopper plate, the chopper knife rides on the inner surface of the chopper plate and directs the bone fragments, sinews and gristle inwardly toward the central portion of the chopper plate as it chops the meat. The central portion of the chopper plate has a funnel-shaped, frusto-conical central passageway within which the bone fragments, gristle and sinews are collected and are urged outward, first passing through the frusto-conical passageway and out the small end of the passageway, into opposed discharge channels which passes through the hub of the plate and communicates with a discharge tube whose distal end is closed or partially closed by a removeable stopper or adjustable clamp.
