Abstract (en)

[origin: EP0357901A2] The process and the related equipment are based on two resin packed ion exchange columns (4, 10) through which the juice (S) to be defecated is flowing. In the first column (4) the juice is partially defecated through ion exclusion thus producing molasses (M) with a satisfactory commercial value, while the defecation process is completed in the second column (10) with separation of the non-sugar residue and recovery of various sugars and non-sugars having a high market value. Treatment on two columns reduces processing time and/or the quantity of resin necessary as compared with one column processes. Polluting waste water is thus completely eliminated.
