A method and apparatus are disclosed for processing meat products containing at least a small portion of liquefiable fats or oils wherein the meat products are extruded into multiple passages or tubes of a shell-and-tube type heat exchanger for heating or cooling the meat product with the fats and/or oils providing lubrication for passage of the meat product through the heat exchanger. With the meat product being trimmings containing substantial amounts of liquefiable fats and oils, the meat product is heated to a rendering temperature within the heat exchanger, rendered or liquefied fats being separated from lean meat portions of the meat trimmings after passage from the heat exchanger, the lean meat portion preferably being immediately refrigerated in order to limit bacterial growth.
