Process: sugar beet extraction

Water used in the extraction processis actually condensed water from the subsequent evaporation steps together with recirculated water from the pulp pressing

Impuresugar juice

Retraining and updating of PC universities staff in AT 18

Process: sugar juice purificationCarbonation: treatment with milk of lime and carbon dioxide. This produces: (i) a precipitate which contains impurities – carbonatation lime; and (ii) sugar syrup

400 tones of lime per day; 18-20 kg lime per tone of beet

Process: evaporation and crystallizationPurified juice is concentrated by evaporation to producea syrup of around 60 – 70 % solids – thick juice.The juice is filtered and transferred to vacuum pans. When the liquor is slightly supersaturated, the pan is seeded with fine icing sugar to initiate crystallization. The mixture is centrifugally separated to extractcrystalline sugar, which is dried, conditioned for packaging or bulk loaded
