Means for curving sausage links
View Patent ↗A device for creating curved sausage links involves extruding an elongated sausage strand having linear protein fibers therein out of an elongated hollow meat emulsion extrusion tube. The flow of meat emulsion through the tube is partially restricted by a restrictor element within the tube which permits a portion of the meat emulsion to pass thereover in a substantially uninterrupted manner, but which requires a separate layer of meat emulsion to have its movement through the tube inhibited by engaging the restrictor element and having to move thereover to exit the tube. When the sausage strand is subjected to heat, the uninterrupted portion is inclined to have more lengthwise shrinkage in the presence of heat than the other layer, thus causing the sausage link to assume a curved configuration. The device has a stuffing tube with the restrictor element therein as described heretofore.
1. A sausage extrusion tube,
comprising,
an elongated hollow tube having a meat emulsion intake end and a meat emulsion discharge end,
a restrictor element in the tube to partially restrict the longitudinal movement of sausage emulsion therethrough so as to divide meat emulsion passing therethrough into separate longitudinal portions comprised of first portion of meat emulsion that passes, engages and is deflected to pass over the restrictor element, and a second portion that does not engage the restrictor element and passes thereby without being deflected, wherein the restrictor element engages a bottom portion of the hollow tube, wherein an inclined ramp is on an upstream end of the restrictor element, wherein the restrictor element has a forward end that terminates in a diagonal undercut front end, and wherein the inclined ramp and the diagonal undercut front end have different angles relative to a longitudinal axis of the tube.
2. The device of claim 1 wherein the cross sectional area of the restrictor element with respect to the cross sectional area in a hollow portion of the tube is between 1-2 to 1-8.
3. The device of claim 1 wherein the restrictor element is located in an off-center position within the tube.
4. The device of claim 1 wherein a downstream end of the restrictor element is approximately 10 mm from the discharge end.
5. The device of claim 1 wherein the restrictor element has a concave arcuate surface on a top surface thereof.
6. The device of claim 1 wherein an open passageway is formed above the restrictor element having an elliptical cross-sectional shape.
