Applying Process Refractometers in Sugar Cane Processing

Raw and final product of sugar refining

Sugar cane, after harvesting, requires processing within a limited time window to avoid sugar loss by inversion to glucose and fructose. The traditional two stage process, milling and processing, may be combined in a single modern production facility. Process refractometers can be found in both operations, making an optical measurement of a solution’s refractive index used to determine the concentration of dissolved solids.

To achieve high quality liquid and crystal sugars and contain production cost, refractometers are employed to deliver accurate in-line Brix and other measurements in the cane sugar refining and milling processes. 

Specific uses of refractometers in sugar production are:

• Product flow adaptation to evaporator capacity to achieve energy savings.
• Extraction process optimization, minimizing the use of water that will need to be removed at the evaporator.
• Separation column feed juice control to adjust concentration to match capacity.
• Quality assurance check on liquid bulk sugar and molasses.
• Vacuum pan automatic and accurate seeding.
• Monitor supersaturation over complete strike of crystallization.
