ABSTRACT:
A method of lubricating the passage of meat emulsion through the stuffing horn of a meat emulsion encasing machine is disclosed, involving forcing meat emulsion under a first magnitude of pressure through a passage into the inlet of a stuffing horn; then providing a first concentric ring of fluid under a second magnitude of pressure around the passage; and then providing a second tapered concentric ring of fluid around the passage with the tapered concentric ring having an outer perimeter of greater depth than its inner perimeter, and with the outer perimeter being in communication with the first concentric ring and its inner perimeter being in communication with the passage. The fluid in the rings is then subjected to a second magnitude of pressure which is greater than the magnitude of pressure imposed on the meat emulsion with the second magnitude of pressure being sufficient to cause the fluid to exit along the entire inner periphery of the second tapered concentric ring to form a fluid film between the meat emulsion and the internal surface of the stuffing horn. An apparatus for performing the method is also disclosed.
