Abstract (en)

[origin: EP1354965A2] Production of refined sugar by tangential filtration of crude sugarcane or sugarbeet juice to obtain a retentate and a filtrate, comprises combining the molasses with the syrup entering the chromatography step. Production of refined sugar by tangential filtration of crude sugarcane or sugarbeet juice to obtain a retentate and a filtrate, softening the filtrate, concentrating the softened filtrate to obtain a syrup, chromatographing the syrup to obtain a sugar-rich extract and an impurity-rich raffinate and crystallizing the extract in two or more stages to obtain refined sugar and molasses, comprises combining the molasses with the syrup entering the chromatography step. An Independent claim is also included for an installation for carrying out the above process, comprising means for performing the above operations.
