Title: A process for rendering animal fats
Inventor: DUFAULT EMMANUEL JOSEPH
IPC: C11B1/12
Filed: 1955-04-18
Abstract: <PICT:0782940/III/1> A process of recovering fat from adipose animal tissue comprises (a) disintegrating the tissue to a finely-ground creamy consistency, (b) heating the resulting mass in a vacuum under such conditions that the fat is liquefied and the mass deaerated, but without any substantial portion of the moisture content being removed, (c) heating the mass to a temperature sufficient to coagulate the protein content, preferably in an inert atmosphere, and finally (d) separating the coagulated protein from the liquid fat. Fig. 2 illustrates an apparatus suitable for the continuous operation of the process.  The raw fat is introduced at 21 into a suitable prebreaker 22.  The resulting small pieces of fatty tissue pass into a hopper 24 and thence through shoot 25 to feeder 26 which regulates the flow of material to disintegrator 27.  The finely-comminuted output is fed by shoot 29 to rotary feeder 30, which serves to introduce the material into heater 31.  This heater is fitted with agitating paddles and is provided with a heating jacket having an inlet 32 and outlet 33.  The heater is maintained under a vacuum of 2.5-25, preferably 5-10, cm. of mercury and at a temperature of 32-60 DEG  C., and is provided with a hood 35 having an outlet 36 through which the atmosphere in the heater may be exhausted. The liquid deaerated slurry is then impelled by pump 38 into a heater 41, which is preferably a continuous heat-exchanger, maintained at 63-82 DEG C., where the protein is coagulated in an inert atmosphere, preferably of nitrogen at atmospheric pressure, supplied from cylinder 45.  The resulting mixture of fat and semi-solid then passes to a separating device 43, such as a centrifuge, where the protein and fat may be separated.  As an optional preliminary step in the process, the adipose tissue may be heated in water for about 20 minutes at about 82 DEG  C. to denature the lipolytic enzymes present. The fat produced according to the process is said to be characterized by a very low content of free fatty acid, and to have good colour and other properties.  The proteinaceous material obtained is edible, and contains a considerable proportion of residual fat, which may be recovered by subjecting the material to high pressure in an hydraulic press.
