An improved method of obtaining oil and high quality fodder from whales and other sea mammals

摘要

Oil is extracted from the blubber of whales or other sea animals by heating the finely divided blubber in the absence of added water to a temperature not exceeding 70 DEG C. under reduced pressure, whereby the oil is melted out and water is evaporated. The blubber is divided to a grain size preferably not exceeding 3 mm. and is heated in a vessel provided with stirring gear and heated indirectly by hot water, steam or low superheated steam. The oil is separated by sieves or by a filter press. Specification 257,582, [Class 91], is referred to.
