Production of white sugars and high-quality liquid sugars

A process for the production of white and liquid sugar from a system comprising one vacuum pan, comprising the steps of:

• melting of a raw sugar source;
• purifying said melted raw sugar by phosphatation to produce a clarified sugar solution;
• batch crystallization of said clarified sugar solution with starting colour of 400-500 IU to white sugar with colour up to 30 IU;
• partial recovery of a first run-off up to 50% of its volume and collection of residual run-off for next crystallization step;
• batch crystallization of a second run-off to white sugar with colour up to 60 IU;
• partial recovery of up to 50% of second run-off back to crystallization;
• admixing of both first and second sugars as a product;
• and
• purifying residual second run-off as a liquid sugar using active carbon, filtration and ion-exchange.
