ABSTRACT:
The invention relates to the manufacture of gelatin, whereby the gelatin is obtained from fresh derms removed from scraps of hides, sinews and tendons within the three hours following the slaughter of the animal; these materials are collected together and washed in cold water then in a solution of dilute sodium hydroxide, subjected to a mechanical separation of fibres until they are reduced to paste, they are then washed several times in cold water in order to eliminate the albumin of the blood, the paste thus washed and rinsed is filtered by pressing until a cake is obtained which is formed of pure collagen; said latter may be stored after dehydration for an indefinite length of time; it may then be subjected to the final cooking, producing a gelatin broth subjected to gelling on a conveyor belt circulating in a chamber maintained at 5.degree. C. and associated with a drying chamber provided with a blower and in which the film of gelatin is conveyed on conveyor belts, the film being wound on a reel on leaving the drying chamber.
