A PROCESS FOR THE PURIFICATION OF SUGAR-CONTAINING JUICES, COMPRISING ALKALIZING A BATCH OF RAW JUICES EXTRACTED FROM DIFFUSION BY A CONTINUOUS AND SIMULTANEOUS ADDITION OF: LIME, AT A CONSTANT FLOW RATE, IN AN AMOUNT RANGING FROM 300 TO 600 G. PER 100 L. OF JUICES, CARBON DIOXIDE AT A VARIABLE FLOW RATE, AND SULPHUR DIOXIDE AT A CONSTANT FLOW RATE IN AN AMOUNT RANGING FROM 4 TO 20 G. PER 100 L. OF JUICES, THE TWO LAST MENTIONED REAGENTS BEING EFFECTIVE TO PRECIPITATE THE IMPURITIES OF THE JUICES FLOCCULATED BY THE LIME, AND THE FLOW OF CARBON DIOXIDE BEING CONTROLLED SO THAT THE PH OF THE MIXTURE GRADUALLY INCREASES FROM THE PH VALUE OF ABOUT 6 FOR THE RAW JUICES TO A VALUE OF ABOUT 11 CORRESPONDING TO OPTIMUM FILTRABILITY.
