Ion exchangers

Ion exchangersIon exchange is used in the sweetener industry for demineralisation.

Demineralisation is a crucial part of high DE hydrolysate refining. Especially for the production of high purity products, where salt content will influence either the further processing and/or the final product quality.

Ion exchange plants are part of a long chain of processing steps from the raw material (starch slurry) to the final product (glucose, fructose syrup, sorbitol etc.).

Ion exchangers Advantages

  • The following impurities will be removed:
        - Organic and inorganic acids
        - Heavy metals (Cu,Pb,Fe)
        - Alkaline earth metals (Ca,Mg)
  • Improved product quality by overall removal of impurities
  • Improved storage stability by partial removal of HMF (hydroxylmethylfurfural)

Ion exchangers Characteristic

  • Flexible plant set-up depending on application
  • Fully automatic operation/regeneration
  • Minimum chemicals and water consumption
