An improved method and apparatus for the continuous vacuum grinding of meat or other products is provided which permits continuous deaeration and grinding so as to materially enhance the organoleptic properties of final meat products such as sausages and the like. Broadly speaking, the apparatus of the invention includes a pumping apparatus together with a grinder and a closed conduit coupling the pump and grinder; deaeration apparatus is also provided which serves to evacuate the meat products prior to grinding, and the latter are maintained in that condition throughout the grinding operation. In preferred forms, use is made of a reciprocating piston-type pump together with remote, separately powered grinding apparatus. In this form of the invention, deaeration is accomplished by means of apertured pistons within the pumping unit which are operatively coupled to a vacuum pump or other suitable evacuating device.

In apparatus for grinding of products including a pumping means for delivering a stream of product to be ground, grinding means including an apertured grinder plate downstream of said pumping means for receiving said product stream and grinding the same, and conduit means operatively coupling the pumping means and grinding means, the improvement which comprises: said pumping means including structure for forming a chamber which can be closed to the entrance of ambient air, means for substantially filling the chamber with meat, mechanical means for closing the meat-filled chamber to the entrance of ambient air and for isolating said chamber from said grinder plate, and means for removing entrapped air within the closed, meat-filled chamber; and said conduit means being imperforate for continuously maintaining said product in said deaerated condition until ground product is expelled from said grinding means.
