Abstract
Abstract A meat emulsion pump is disclosed herein which is well suited for use with meat processing machines such as frankfurter or sausage stuffing machines. The pump includes means for removing entrapped air bubbles from the meat emulsion and has a vacuum pump operatively connected thereto for removal of the released air from the pump interior. The vacuum pump communicates with the pump cavity between the pump discharge opening and the pump intake opening. The intake opening is positioned so that the emulsion enters the cavity at a location wherein the cavity has already begun to expand or increase. The pump cavity configuration of the pump is such that the meat passes through the pump in a smooth flowing manner without turbulance being created in the product thereby eliminating smear and ''''fat out'''' damage. An accumulator means is fluidly connected to the conduit extending from the pump to the meat processing machine. The accumulator means is adapted to supply the pumped emulsion to the processing machine under a constant pressure. The accumulator means also includes means for starting and stopping the pump so that the said constant pressure is assured and so that the emulsion is not recirculated.
