Gelatin Processing Machines

09.

Gelatin is derived from Degreased Crushed Bones (DCB) through acid alkali treatment. DCB are first treated for removal of inorganic salts in bone which is referred to as Ossein.

Ossein is then treated for partial hydrolysis. During the partial hydrolysis the collagen material is softened from the non-collagen. Non-Collagen gets removed. The temperature is controlled during maceration and liming to avoid any yield losses. Ossein is then washed with water and chemicals then taken for Gelatin extraction.

Gelatin is extracted in the form of weak liquor, which is then filtered and passed through ion exchange (deashing system) for reduction of the dissolved ash(dissolved minerals) in the gelatin solution. This de-ionized weak liquor of Gelatin is then concentrated under vacuum to avoid any destruction to the basic tri skeleton structure of gelatin.

Concentrated liquor is then passed through sterilization system followed by extrusion for making noodles to facilitate proper drying of Gelatin.

Gelatin drying is very critical process since fast heating will melt the gelatin instead of drying and slow drying will result in gelatin moisture out of limits so Gelatin is dried very carefully with dehumidified air by gradual increase of temperature gradually to 60OC.

Dried Gelatin is then crushed to required mesh size as per the market demand. During Gelatin manufacturing DCP is produced as a byproduct. Which is a main constituent for the cattle and poultry feed.
