On-line color monitoring of sugar in real-time
A major raw sugar producer seeks to improve process control methods to reduce production costs while maintaining the color characteristics of the sugar as required by their customers. Supplying sugar with lower ICUMSA color (higher quality) than required in order prevent customer rejection results in increased production costs.
Current process control methods involve color measurements of sugar in a solution. These methods are time consuming and are generally not useful for real-time process control.
