Abstract

29 METHOD AND DEVICE FOR PURIFYING HIGH MELTING ORGANIC RAW PRODUCTS OR COMPOUND MIXTURES BY MEANS OF FRACTIONAL LAVER CRYSTALLISATION ABSTRACT 5 THIS INVENTION RELATES TO A METHOD AND A DEVICE FOR PURIFYING AND/OR SEPARATING PREFERABLY HIGH MELTING ORGANIC RAW PRODUCTS OR COMPOUND MIXTURES CONTAINING, IN PARTICULAR, HIGH MELTING AND/OR DEGRADABLE STEROLS, BY LAYER CRYSTALLISATION ON FIRST HEAT EXCHANGER SURFACES. THE RAW PRODUCT IS RECEIVED IN A SOLVENT OR SOLVENT MIXTURE, AND THEN BROUGHT INTO CONTACT WITH HEAT EXCHANGER SURFACES. 10 THE DESIRED PRODUCT CRYSTALLISES ON THE HEAT EXCHANGER SURFACES BY SLOW COOLING. SOLVENT EVAPORATING DURING THE CRYSTALLISATION OR SWEATING PROCESS IS CONDENSED AND RETURNED TO THE MIXTURE.
