Abstract (en)

[origin: EP1889898A1] A process for dry fractionation of fat and oil including the steps of melting fat and oil, crystallizing the melt by cooling to obtain a crystal slurry, separating the slurry into a first crystalline fraction and a first liquid fraction, and sweating the first crystalline fraction by heating while pressing to obtain a second crystalline fraction and a sweated-out second liquid fraction. A high purity crystalline fraction (high-melting components) and middle melting fraction can efficiently be separated from fat and oil without using a wetting agent or any special implement. The thus fractionated fat and oil are suited for use in chocolate, etc.
