Cane Sugar Production
In order to convert sugar cane into sugar there are two processes that take place: milling and refining. Although ion exchange resins are not used in the milling stage, it is useful to understand mill operations first.
In the cane sugar refining process, sucrose is extracted from the sugar cane stalk in a cane sugar mill, purified and crystallized into a tan colored raw sugar. The sugar we consume must be further refined so as to not impart color, flavor or odor to the foods and beverages it sweetens. In a cane sugar refinery the raw sugar is remelted and the sucrose is further decolorized with ion exchange resins, carbon or bone char and crystallized into white sugar or delivered as liquid in bulk tanker trucks for industry, consumers and confectioners. Liquid sugar can be further refined with ion exchange resins to remove ash or inverted as required for the application.
There is an impact on the ion exchange resin itself during these operations. Installing the correct product with the correct specifications as well as understanding the cleaning and regeneration procedures is critical to overall operational performance.
