Dry fractionation method for oil or fat |
摘要 |
The purpose of the present invention is to provide a method, whereby, in the dry fractionation of an oil or fat, a decrease in solid-liquid separation efficiency, said decrease being caused by the engulfment of a filtrate fraction into a crystal fraction after crystallization and press filtration, can be prevented and thus the crystal slurry can be efficiently separated after the crystallization. A method for the dry fractionation of an oil or fat, said method comprising, before or after crystallization, adding a definite amount of a filtration aid followed by mixing and then press-filtering the thus obtained crystal slurry. Thus, the crystal slurry can be easily separated into a crystal fraction with little engulfment of a liquid fraction and the liquid fraction. |

1. A method of separating a crystal during a dry fractionation of oil-and-fat comprising, adding and mixing a filtration aid to a crystal slurry after crystallization in an amount of 15 to 120% by weight with respect to a solid fat content crystal amount in the crystal slurry and subjecting the mixture to press-filtering, wherein:
the solid fat content crystal amount in the crystal slurry is 10 to 35% by weight, the filtering aid is at least one selected from diatomaceous material, perlite material, and glass beads, and the filtration aid has an average particle diameter of 1 to 60 μm. |
