Observing granulation after addition a small amount of water to a sugar powder

LIR technology is specifically suited to closely monitor granulation processes since FPM and PCF process signatures effectively separate small and large particles and characterize the uniformity of the mixture. The video shows a real-time measurement of granulation of common sugar. In this test, after observing a signal for dry powder, several droplets of water (6 ml) are added to a 1.5 liters of sugar powder being processed in a laboratory mixer. The process signature then clearly shows events of agglomeration and formation of dense granules within the powder volume, and the increased granule content with time. The video illustrates the application of Lenterra Inline Rheometer to monitoring HSWG and determination of granulation end-point.
