摘要
Protein and fat are recovered by low-temperature melting of raw animal fatty material (e.g. pork trimmings) by a process comprising comminuting the raw material into fine particles of size not above a few mm. (e.g. 2-3 mm.); intimately mixing the comminuted material with a medium having a specific heat lower than the raw material and previously heated to a temperature well above the melting-point of the fat (e.g. 70-120 DEG C.), the relative quantities of raw material and heated medium being such that the heating effect upon the particles of raw material is below the value at which the protein in the raw material coagulates; and finally separating the product, e.g. in a centrifuge, to produce a protein phase and a fat phase. The heated medium is preferably previously separated fat. A plant for carrying out the process is described.ALSO:Protein and fat are recovered by lowtemperature melting of raw animal fatty material (e.g. pork trimmings) by a process comprising comminuting the raw material into fine particles of size not above a few mm.
