METHOD AND APPARATUS FOR THE PRODUCTION OF STEARIN FROM FAT OF ANIMAL OR PLANT ORIGIN. A METHOD IS CARRIED OUT SUCH THAT DURING THE DURATION OF A PRODUCTION RUN, A SHARP SEPARATION BETWEEN THE STEARIN PHASE AND THE OIL PHASE IS MAINTAINED AT A CONSTANT RATE, TO ACHIEVE AN OPTIMUM QUALITY OF STEARIN AND STEARIN YIELD. CRYSTALLIZED OIL OF A TEMPERATURE FROM 10°C TO 40°C IS FED INTO INLET (12) OF A NOZZLE-TYPE CENTRIFUGE (11) WHICH IS NOT SELF-EMPTYING AND IS EQUIPPED WITH A STACK OF PLATES (15) AND A STATIONARY GRIPPING DEVICE (16) FOR THE OIL PHASE. THE SOLID PHASE IS GUIDED THROUGH FLOW CHAMBERS TAPERING TOWARDS THE NOZZLES (20) ANDDISCHARGED THROUGH THESE NOZZLES. TO REALIZE A HIGH DEGREE OF SEPARATION BETWEEN THE STEARIN PHASE AND THE OIL PHASE, THE RATIO BETWEEN THE FEED RATE IN I/H AND THE NOZZLE CAPACITY IN I/H IS ADJUSTED IN THE RANGE BETWEEN 2:1 AND 4:1. THE METHOD IS USED FOR STEARIN PRODUCTION FROM ANIMAL OR PLANT FATS. (FIG.2)
