A detection unit configured to detect a leakage hole in an intestine suspended on a tubular member having a perforated portion that is configured to distribute a flow of liquid through the perforated portion and thereby pressurize the intestine, when the intestine is being moved with a non-zero velocity (V) along the longitudinal axis of the tubular member is disclosed. The detection unit comprises an electrically conducting and axially extending sleeve-shaped surrounding portion that at least partly surrounds the circumference of the tubular member and an electric circuitry arranged and configured to measure an electric quantity established between the surrounding portion and the liquid pressurizing the intestine.

An intestine detector comprising a first end detector and a second end detector arranged a non-zero distance from the first end detector, wherein the intestine detector comprises an intermediate detector arranged and distanced between each of the end detectors in such a configuration that the intermediate detector will be electrically connected to any intestine suspended on the end detectors and extending between the first end detector and the second end detector.

A machine including a supply of gelling agent (45), a supply of acidic buffer solution (47), a third supply of food inlet (51) connected to a source of food (53), a mixer (27) connected to the gelling agent and acidic buffer solution supplies, for delivering a mixture of gelling agent and acidic buffer solution, and a co-extruder (31) fed with food (51) and with said mixture, for extruding the food at the center and the mixture at the periphery, so as to obtain the expected food product at the outlet.

An apparatus for processing a foodstuff material is provided, specifically for producing sausage products from sausage meat. The apparatus includes a stationary housing which has a wall and which can be connected in fluid-conducting relationship to a conveyor pump, and has a discharge opening for delivery of the foodstuff material. Arranged within the housing is an element for partially swirling the foodstuff material within the housing, which is rotatable relative to the wall and along which in operation at least a partial amount of the foodstuff material to be conveyed flows. The rotatable element ends within the housing before the discharge opening for delivery of the foodstuff material. The apparatus can produce a string with a substantially cylindrical outer contour from a foodstuff material like sausage meat.

The present disclosure relates to packaging equipment for continuous automatic net sleeving of a casing, a shirring machine and a packaging method. The packaging equipment is provided with a shuttle; a first gripper, capable of being opened or closed to release or clamp and fix the shuttle; a second gripper, capable of driving an open end of the net bag to make reciprocating motion between a first position and a second position on the shuttle when being closed, and capable of allowing the net bag to move freely in a net bag conveying direction when being opened; a third gripper, configured to clamp the open end of the net bag and pull the net bag to sleeve a whole shirred casing in a penetrating mode; and a fourth gripper, configured to pull the net bag, and designed to be capable of moving with the third gripper.

A system and method for processing a coextruded meat product including a casing enclosing a meat batter after brining in which a heated, high velocity air stream is applied to the coextruded meat product thereby mechanically removing moisture from a surface of the casing and cooking the coextruded meat product. This system and method can further improve the ability for a liquid coating to be added to the coextruded meat product in a non-drenching manner because of the superior surface preparation of the casing by the jets.

An improved process for the manufacturing of emulsion-type sausages into a flattened form-factor that does not require the use of individual molds.

The present invention relates to cellulose casings, whether reinforced or not, capable of transferring color to the product stuffed therein. These casings contain a food dye transferable to the stuffed product during processing. The present invention also relates to the method of obtaining the casing and the product stuffed in said casing.

The present invention relates to a method, a coextrusion apparatus and a filling machine including a coextrusion apparatus of the type in question, wherein, during production of the sausage strand, the ratio of the volume flow of the casing material to the volume flow of the inner mass is variable along the sausage strand.

The present invention relates to a tubular, seamless, biaxially stretched, smoke-permeable and water vapour-permeable, colouristically neutral and transparent, single-layer food casing formed from a mixture including 50 to 95% by weight of aliphatic (co)polyamide, 3 to 40% by weight of at least one vinyl (co)polymer having units of N-vinyl-2-pyrrolidone and 1.5 to 7.0% by weight of at least one aliphatic diol and/or aliphatic polyol, based in each case on the weight of the mixture. The diol and/or polyol is homogeneously distributed in a matrix formed by the aliphatic (co)polyamide. The food casing is produced by an extrusion method with biaxial tube stretching and subsequent heat-setting. It is particularly suitable as synthetic sausage casing, especially for raw sausage, such as salami or mettwurst.
