Abstract Four typical pharmaceutical granulations were used to measure the enhanced drying performance of a laboratory-sized microwave fluid-bed processor, the design and construction of which were presented in Part I of this work (preceding paper). Results demonstrate improvements in observed drying rates by as much as sixfold depending upon the granulation type and drying conditions. At a low inlet temperature (30°C), drying was achieved with microwave power inputs of 100–125 W/liter of working capacity, whereas similar targeted moisture levels were unattainable using conventional fluid-bed drying. Microwave energy available for heating and drying was 68 to 86% of the total microwave energy inputted.
