Thermal effusivity and power consumption may help predict granulation end point in high-shear granulators. In this study, power consumption was monitored and compared with percent relative standard deviation (RSD) on thermal effusivity measured at-line. Lactose monohydrate, microcrystalline cellulose, and magnesium oxide were granulated, and the effect of load size on granule growth in a fixed-volume granulator was evaluated using three load levels. Load size, liquid addition rate, and impeller speed were measured, and the correlation among RSD on effusivity, power consumption, mean granule specific surface area, and granule compressibility index were determined.

The Merits of Failure

If there's one word I (and probably most people) have come to fear more than all others, it's "failure." We've been conditioned since grade school that failure is shameful and punishment worthy. Maybe even something we should tuck away in our knapsack, sneak past Mom and Dad, tear into little pieces, and hide under the carpet.
