Embodiment 1

[0063] Post-rounding, eg, of a straight collagen NDX casing caliber 21 sold by Viscofan S.A. / Spain with 22% moisture relative to its total weight and 17% glycerol as plasticizer, by heat shrinking.

[0064] Parent rolls of chemically cross-linked NDX casings (1) are manually unwound, conveyed through conveyor roller pairs (3) and further passed through annular fans (6) around heat regulating rollers (7) to heated regulating rollers (7) ) and a small roller (8) composed of a pair of receiving rollers, such as figure 1 shown.

[0065] The NDX casing is aerated to 200 mbar and its bubbles are captured between the conveyor roller pair (3) and the roller pair formed by the hot regulating roller (7) and the small roller (8). Then, the casing bubble (4) tightly surrounds 3 / 4 around the heat regulating roller with a diameter of 115mm. Thus, the casing bubble (4) forms a radial bend (12) along its innermost ring (13), as Figure 2a shown.

Embodiment 2

[0080] Rolls of straight collagen casing Colfan B gauge 19 sold by Viscofan S.A. / Spain were post-rounded by applying the same technique as described in Example 1 of the present invention.

[0081]

[0082] No collagen is "rubbed away".

[0083] Sir / Sor 1.35

[0084] The casing of the full circle after the gain of the embodiment of the present invention 2 is further compared with the casings of comparative examples A and B, the casings of comparative examples A and B:

[0085] Clear visual detection of collagen "rubbed off" along the inner ring.

[0086] Sir / Sor 1.19

Embodiment 3

[0088] R2L-SR is a non-edible straight collagen casing sold by Viscofan S.A. Pamplona / Spain. It was rounded after the line according to the following embodiment 1 of the present invention.

[0089] first along figure 1 The casing collector buffer not shown in the guide to compensate for speed deviations leads directly from the R2L caliber 39 of the product dryer.

[0090] Such as figure 1 Described, casing moisture improves when passing through water ring sprayer (5).

[0091] Post-rounding of R2L-SR was performed as described in Example 1 of the present invention.

[0092]

[0093] No collagen is "rubbed away".

[0094] Sir / Sor 1.30

[0095] The casing of the full circle after the gain of the embodiment of the present invention 3 is directly compared with the casing of comparative example C, and the casing of comparative example C:

[0096] Clear visual detection of collagen rubbed off along the inner ring.

[0097] Sir / Sor 1.10

Abstract

The invention relates to a method for obtaining a round collagen casing and the casing obtained by the same. The method is based on post-roundness modifying of a straight collagen casing by controllable thermal contraction.

Description

technical field [0001] The present invention relates to a method for obtaining round collagen casings, based on post-rounding of straight collagen casings, and casings obtained by said method. Background technique [0002] Most natural casings exhibit a very common round shape, such as ring bologna, ring liver sausage and mettwurst. The artificial casing industry has been working hard to develop competitive alternatives. [0003] Patent application US4356201 describes round collagen casings produced by extrusion of aerated collagen tubes located in the section responsible for the continuous transformation of the straight tube into a round shape and its further transport through the production line during crosslinking and drying Specially designed swivel section. [0004] In a variation of this basic technique, for thin-walled edible rounds, extruded collagen tubes can be coagulated immediately by ammonia treatment on the inside and a water-dissolved saline solution on the ...
