Abstract
<PICT:0658261/III/1> Fish livers are mechanically grated, mixed with hot water, and centrifuged in a separator provided with outlet nozzles in the bowl wall through which water and solid particles are discharged as a sludge, a part of the sludge being reintroduced into the sludge space of the bowl in order to minimize the quantity of hot water used, especially in the case of apparatus installed on motor trawlers. In the installation shown, the livers are introduced into a liver grater 1, preferably of the type described in Specification 614,972, and pumped into a stirred, double-jacketed heating tank 5 and then to a centrifuge 9 of the type referred to above. The oil is collected in a tank 10 and pumped either direct to storage or through a heater and cylinder separator, when a further quantity of sludge is separated. The sludge concentrate discharging from the nozzles in the bowl is partly reconducted to the sludge space of the bowl through the pipe 14. Water for mixing with the liver mass, the grated livers, and the material in the centrifuge, is heated by a coil 21 in an oil-fired boiler 15 and delivered through pipes 24, 23 and 25, while hot water for circulating in the jacket of the tank 5 passes directly from the boiler through the pipes 16 and 20. Ordinary sea water may be used if desired.
