A process optimization strategy of a pulsed-spray fluidized bed granulation process based on predictive three-stage population balance model

In this work, a three-stage population balance model (TSPBM) was developed for a pulsed top-spray fluidized bed granulation (FBG) process. The batch top-spray FBG process was divided into three stages based on the analysis of granule properties evolution and different granulation mechanisms were considered in each stage of the TSPBM. In each stage, population balance model (PBM) describes the evolution of granule size distribution (GSD), and...
