Improvement of a pharmaceutical powder mixing process in a tote blender via DEM simulations
| Contributor(s):: Benedict Benque, Luca Orefice, Thomas Forgber, Matthias Habeler, Beate Schmid, Johan Remmelgas, Johannes Khinast
An industrial-scale pharmaceutical powder blending process was studied via discrete element method (DEM) simulations. A DEM model of two active pharmaceutical ingredient (API) components and a combined excipient component was calibrated by matching the simulated response in a dynamic angle of...

Multi-dimensional population balance modeling and experimental validation of continuous powder mixing processes
| Contributor(s):: Sen, Maitraye, Singh, Ravendra Vanarase, Aditya John, Joyce, Ramachandran, Rohit
It has been recognized that the application of quality by design (QbD) to continuous processing in the pharmaceutical industry leads to better process control, improved product quality and mitigates scale-up issues (Schaber et al., 2011), whereby a component of QbD involves the development...

Mathematical development and comparison of a hybrid PBM-DEM description of a continuous powder mixing process
| Contributor(s):: Sen, Maitraye, Dubey, Atul Singh, Ravendra, Ramachandran, Rohit
This paper describes the development of a multidimensional population balance model (PBM) which can account for the dynamics of a continuous powder mixing/blending process. The PBM can incorporate the important design and process conditions and determine their effects on the various critical...
