Abstract
The present invention relates to a method of producing gelatine, the method comprising the steps of: providing animal material containing collagen; cutting the animal material with at least one fluid cutting jet to form animal material sections; hydrolysing the collagen in the animal material sections to form gelatine; and isolating the gelatine. The invention also relates to a fluid jet cutting device and to the use of a fluid jet cutting device in the production of gelatine. The invention is particularly useful in the production of gelatine from pig skin and/or cow hides and/or fish skin.
Claims15
A method for producing gelatine, the method comprising the steps of:
- a. providing animal material containing collagen;
- b. cutting the animal material with at least one fluid cutting jet to form animal material sections;
- c. hydrolysing the collagen in the animal material sections to form gelatine;
- and
- d. isolating the gelatine.
The method of any of the preceding claims, wherein the method further comprises the steps of:
- providing the animal material using a first belt conveyor defining a feed direction, wherein the first belt conveyor transports the animal material with a feed velocity in the feed direction;
- cutting the animal material using at least one fixed fluid jet cutting head;
- and
- cutting the animal material using at least one moving fluid jet cutting head, arranged to provide a moving fluid cutting jet, the moving fluid cutting jet being arranged to achieve a first velocity component on the first belt conveyor, said first velocity component being perpendicular to the feed direction.
The method of any of the preceding claims, the method further comprises a step of cutting the animal material using the at least one moving fluid jet cutting head which is arranged to provide a moving fluid cutting jet having a second velocity component on the first belt conveyor along the feed direction, said second velocity component being substantially equal to the feed velocity.
The method of any preceding claims, wherein the method further comprises cutting the animal material with a fluid jet cutting device comprising:
- a first belt conveyor defining a feed direction;
- at least one fixed fluid jet cutting head being arranged to provide a fluid cutting jet to the first belt conveyor;
- a second belt conveyor defining a second feed direction;
- and at least one fixed fluid jet cutting head being arranged to provide a fluid cutting jet to the second belt conveyor,
- wherein said feed direction and said second feed direction are non-parallel, preferably wherein the feed direction and the second feed direction are substantially orthogonal.
The method of any of the preceding claims, wherein the fluid cutting jet comprises an abrasive material, wherein preferably the abrasive material comprises a solid food-grade material.
The method of any of the preceding claims, wherein the animal material is animal skin, preferably pig skin, beef hide, or fish skin.
A fluid jet cutting device for cutting animal material for the production of gelatine, said fluid jet cutting device comprising:
- a. a first belt conveyor defining a feed direction;
- b. at least one fixed fluid jet cutting head, preferably at least three fluid jet cutting heads, arranged to provide a fixed fluid cutting jet;
- and
- c. at least one moving fluid jet cutting head, arranged to provide a moving fluid cutting jet, the moving fluid cutting jet being arranged to achieve a first velocity component on the first belt conveyor, said first velocity component being perpendicular to the feed direction.
