Abstract
The present invention relates to a method for demineralizing beet sugar thin juice with a solids content of 10 to 40% by weight by first passing said juice through a solid bed of a weakly acidic cation exchanger in hydrogen form at 10.degree. to 60.degree. C. at a rate of 10 to 180 bed volumes per hour and a contact time of 20 to 360 sec. and then passing the juice through a solid bed of a weakly basic anion exchanger in hydroxyl form in the same temperature range, at the same rate and for the same contact time.
