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.
