摘要：
Method for producing refined sugar from sugared juice, such as raw juice from sugar cane or from sugar beet, containing sugar and impurities, which comprises the operations 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.
