Decolorization - Sugar

Introducing ion exchange resins for de-colorization in the sugar refinery industry is one of the best techniques due to the system flexibility and low operation cost. Color bodies that remain in cane after pretreatment are hydrophobic and anionic. Ion exchange resins used here act as two main processes; ion exchange & adsorption. Negatively charged colorants get eliminated by strong base anions (SBA) in chloride form. Non-polar colorants show hydrophobic interaction with adsorption between color bodies and the resin pores inside the resin bed.
SBA can be either styrene or acrylic. Macro-porous resins are common in the refinery field due to high de-colorization capacity than gel type. Gel resins can use when low color syrup is required. Acrylic resins are more resistant to high color feed levels and less hydrophobic interaction with non-polar colorants. But, Styrenic resins have a more effective decolorizing rate and better capacity in low color feed levels.

Demineralization / Deashing - Sugar

Sugar syrup carries salts and minerals from ashes and organic compounds entering the de-ashing unit. The stream passes the strong acid cation resin bed to remove positively charged ions. It can also remove some proteins in an acidic environment. Then syrup leaves the cation bed and carries negatively charged ions with eliminated cations as free acids. Then it enters the weak base anion bed, and these resins result in ion-free syrup.

Beet Thin Juice Softening

The beet plant is the primary source of sucrose in the world. Raw juice consists of undesirable compounds. Lots of them remove as precipitation with the addition of lime. In this step, there will be the hardness in thin juice and should be removed before entering the evaporator to prevent the evaporator from scaling.
The most recent technique is an ion-exchanging method using strong cation acids.

Demineralization - Sweetener

Demineralization removes ash, proteins, and color from glucose syrup. Demineralization accelerates the performance of enzymes of dextrose solution by removing ashes that are present there. Also, the salts; added to the dextrose solution to increase isomerase enzyme performance were released via demineralization.
In the dextrose solution, while passing the resin bed, sugars, ashes, colorants, and proteins can be exchanged or adsorbed onto the resin bed. Strong acid cations and strong base anions are used to remove these impurities.
