Abstract:
    The present invention concerns method for producing refined sugar from sugared juice, such as raw juice from sugar cane or from sugar beet, containing sugar and impurities. The method includes the steps of tangential filtration of the sugared juice in order to obtain a retentate and a filtrate, softening of the filtrate in order to obtain a softened filtrate, concentration of the softened filtrate in order to obtain a softened syrup, chromatography of the softened syrup in order to obtain an extract enriched in sugars and a raffinate enriched in impurities, crystallisation of the extract in two or more crystallisation/separation steps in order to obtain refined sugar and a run-off, and combination of the run-off with the softened syrup in order that they are both subjected to the chromatography operation. The present invention also concerns equipment to implement the said method.
