   Peer-reviewed journal | 12 Nov 2024 | Contributor(s):: Peter Boehling, Johan Remmelgas, Mohammadsadegh Salehi, Johannes Poms, Rúben Martins Fraga, Manel Bautista, Johannes G. Khinast, Emmanuela Gavi, Michela Beretta

   Powder blending is a critical step in pharmaceutical manufacturing that can impact product quality such as tablet tensile strength. This study utilized the Discrete Element Method (DEM) to investigate blending in a 5-liter mini-batch and a 2-liter Turbula blender. DEM parameters were calibrated...

2. Improvement of a pharmaceutical powder mixing process in a tote blender via DEM simulations

   Peer-reviewed journal | 04 Jun 2024 | 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...

3. A modified Kushner-Moore approach to characterising small-scale blender performance impact on tablet compaction

   Peer-reviewed journal | 03 Jun 2024 | Contributor(s):: Hikaru G. Jolliffe, Martin Prostredny, Carlota Mendez Torrecillas, Ecaterina Bordos, Collette Tierney, Ebenezer Ojo, Richard Elkes, Gavin Reynolds, Yunfei Li Song, Bernhard Meir, Sara Fathollahi, John Robertson

   Continuous Direct Compaction (CDC) has emerged as a promising route towards producing solid dosage forms while reducing material, development time and energy consumption. Understanding the response of powder processing unit operations, especially blenders, is crucial. There is a substantial body...

   Peer-reviewed journal | 09 Jun 2023 | 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...

6. Mathematical development and comparison of a hybrid PBM-DEM description of a continuous powder mixing process

   0.0 out of 5 stars 

   Peer-reviewed journal | 09 Jun 2023 | 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...
