Development of a Controlled Continuous Low-Dose Feeding Process
Peer-reviewed journal | 09 Jun 2023 | Contributor(s):: Fathollahi, Sara, Kruisz, Julia, Sacher, Stephan, Rehrl, Jakob, Escotet-Espinoza, M. Sebastian, DiNunzio, James, Glasser, Benjamin J., Khinast, Johannes G.
This paper proposes a feed rate control strategy for a novel volumetric micro-feeder, which can accomplish low-dose feeding of pharmaceutical raw materials with significantly different powder properties. The developed feed-forward control strategy enables a constant feed rate with a minimum...

A solution for low-dose feeding in continuous pharmaceutical processes
Peer-reviewed journal | 09 Jun 2023 | Contributor(s):: Sacher, S, Heindl, NUrich, JAA, Kruisz, J, Khinast, JG
Continuous feeding of small quantities of powder is increasingly applied in pharmaceutical manufacturing. With that regard, what is crucial is not only the feasibility, but also the accuracy and stability. To enable stable processing, low amounts of various agents, e.g., lubricants, can be used....
