Refined sugar is widely used around the world. Some end users, such as soft drink manufacturers, dairy industry, pharmaceutical industry, beverage, candy factories, etc., prefer to use premium refined sugar. The specifications of sugar vary slightly depending on the customer. Production of refined sugar: Two techniques can be used to produce refined sugar from crude sugar: one is using activated carbon, and the other is ion exchange resin.

The cost of various activated carbon methods commonly used in sugar factories has been constantly increasing, so it is necessary to find an alternative method to decolorize syrup.

Compared with traditional activated carbon methods, ion exchange resins have certain advantages, as described in detail below:

Resin treatment:

1. Resin column operation can be used

2. Resin can be easily regenerated with inexpensive regenerants

3. By recycling the treated saltwater, the problem of sewage can be eliminated

4. Color of resin after non leaching and absorption

Activated carbon treatment

1. Only batch processing operations are available

2. Regeneration is very difficult, only thermal regeneration is possible

3. The disposal issue of filtered carbon composition needs to be discarded

4. After a certain amount of contact time, carbon may begin to leach color
