The on-line determination of purity in sugar manufacturing process streams

摘要

A new technology for on-line determination of sucrose concentration in process streams is described. The use of this sucrose meter with other on-line devices that determine refractometric dry substance or density to monitor process stream purity in real time is reported. In pilot scale trials purity was determined in real time using the sucrose meter coupled with a microwave density meter, a process refractometer and a radio frequency probe. The results of on-line purity monitoring trials indicate potential for improving unit process throughput and product consistency in sugar manufacture.
