| 摘要 |
The invention relates to a method for fractionating an oil using a fractioning system, preferably a natural oil, in particular a vegetable or animal oil, which yields one or more solid fractions and a liquid fraction, wherein a) the optionally pretreated, heated natural oil is mixed with a solvent and is cooled in one or more steps in a cooling reactor, through which the oil/solvent mixture continuously flows, to a fractionation temperature such that by way of crystallization a mixture composed of a crystalline solid fraction and a liquid fraction is formed, b) whereupon the mixture from step a) is continuously separated centrifugally into the liquid and the crystalline phase or fraction. Furthermore a separator comprising a feed for washing liquid, which removes the oil from the heavy phase in the counter-flow, is provided. |
