METHOD AND MEANS FOR MAKING COEXTRUDED SAUSAGE STRANDS

摘要

An extrusion attachment (10) for sausage making machines have three concentric tubes (12, 42, 54) with the inner tube defining a first passageway (60), the space between the inner (12) and intermediate (42) tubes comprising a second passageway (62), and the space between the outer tube (54) and the intermediate tube (42) defining a third (83) passageway. The diameter of the inner tube (12) is small so that meat emulsion (70A and 70B) passing into the inner tube (12) is subjected to a higher pressure than that of the pressure in the second passageway (62). The lower pressure meat material in the second passageway (62) is thinly coated on the strand of the high pressure meat material extruded from the inner tube (12). A thin layer of collagen material (72) is extruded from the third passageway (83) for deposit on the outer surface of the meat layer extruded from the second passageway (62). An alternate extrusion attachment (84) 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.
