Title:

METHOD OF DRY-FRACTIONATING FAT AND STATIONARY CRYSTALLIZATION APPARATUS

Document Type and Number:

WIPO Patent Application WO/1999/013034

Kind Code:

A1

Abstract:

A method of dry-fractionating fat for subjecting raw fat to stationary crystallization and solid-liquid separation, characterized by cooling preliminarily an objective fat, dividing the same into small parts inside a large vessel, and charging them in parallel into multi-stage crystallization trays; and a stationary crystallization apparatus used for this method. This method drastically saves labor by employing a filter press without sacrificing the yield of high-melting fractions, can pour a predetermined quantity of the raw oil in a homogeneous state into each crystallization tray within a short time, can lower a preliminary cooling temperature, can save labor by the filter press by recycling low-melting fractions, improves the yield of the high-melting fractions over that by the conventional methods, and stabilizes the quality.
