Sugar Decolorization

Ion exchange resins offer greater operational efficiency and improved process hygiene than either powdered or granular carbon and are rapidly becoming the media of choice for cane sugar refiners seeking to remove color from liquid or crystal sugar products. Strong base type I anion resins in the chloride form remove color by ion exchange or adsorption.

Thin juice ion exchange softening positively affects downstream operations, eliminating the need for descaling evaporators and improving the efficiency of heat transfer while improving boiling characteristics and resulting sugar quality. It is important to note that cane juice is typically “harder” than beet juice a can require larger softening systems and more regenerant.
