Abstract:The study presents the die filling process of pharmaceutical powders using high-speed camera imaging. The objectives are to qualitatively visualize and to quantify the powder flow. A model die filling system with a shoe for powder storage and a moving die underneath the shoe was designed. The die filling process is captured through a high-speed camera and the images allow flow type identification and flow rate calculation. Correlations are generated to predict the fill ratios and flow rates based on particle s… Show more
