Abstract
An extrusion attachment for sausage making machines have three concentric tubes with the inner tube defining a first passageway, the space between the inner and intermediate tubes comprising a second passageway, and the space between the outer tube and the intermediate tube defining a third passageway. The diameter of the inner tube is small so that meat emulsion passing into the inner tube is subjected to a higher pressure than that of the pressure in the second passageway. The lower pressure meat material in the second passageway is thinly coated on the strand of the high pressure meat material extruded from the inner tube. A thin layer of collagen material is extruded from the third passageway for deposit on the outer surface of the meat layer extruded from the second passageway. An alternate extrusion attachment has only two concentric tubes as defined above with an elongated hollow casing on the outer surface of the two tubes adapted to receive a coextruded strand of sausage.
