DRY OIL-AND-FAT SEPARATION METHOD

Title:

DRY OIL-AND-FAT SEPARATION METHOD

Document Type and Number:

WIPO Patent Application WO/2010/089973

Kind Code:

A1

Abstract:

Disclosed is a dry oil-and-fat separation method of high yield and high separation accuracy, which uses agitation and crystallization in order to prevent problems with thickening of the crystal slurry and decreased solid/liquid separation efficiency in the crystallization/press-filtering process of dry separation of oil-and-fat containing highly crystalline SUS. In dry separation, the crystallization/press-filtering process is divided into multiple steps and repeated, to concentrate the SUS in each crystal fraction and yield SUS-rich oil and fat. Subdivision into multiple steps makes it possible to keep the crystallinity of the crystal slurry in the crystallization/press-filtering process within a range so that the crystal slurry can be transported by pump, and to increase solid/liquid separation efficiency.
