Abstract An instrument is described that can measure colour rapidly on solid, crystalline sugar, wet or dry, and with good correlation to the ICUMSA colour measurement at 420nm. Sugar colour can be measured in a few seconds, on sugar moving on a belt, or in a screw or a hopper conveyor. The system has been used on white crystal sugar, and offers rapid control of sugar going to packaging or storage. The system can be applied to monitor colour on sugar coming out of batch centrifuges, for a new level of quality control. Recent work has shown that the system can be used to measure colour in raw sugars, and in soft brown or yellow sugars. Results are reported and discussed. |
