Videometric mass flow control: A new method for real-time measurement and feedback control of powder micro-feeding based on image analysis
Contributor(s):: Madarasz, L, Kote, AGyurkes, M, Farkas, A, Hambalko, B, Pataki, H, Fulop, G, Marosi, G, Lengyel, L, Casian, T, Csorba, K, Nagy, ZK
The present paper reports the first monitoring and control of ultra-low dose powder feeding using a camera image-based mass flow measurement system. Caffeine was fed via a single-screw microfeeder as a model active pharmaceutical ingredient (API). The mass, mass flow and sizes of the particles...

Real-time feedback control of twin-screw wet granulation based on image analysis
Contributor(s):: Madarasz, Lajos, Hoffer, Istvan, Szabo, Barnabas, Csontos, Istvan, Pataki, Hajnalka, Demuth, Balazs, Szabo, Bence, Csorba, Kristof, Nagy, Zsombor Kristof, Marosi, Gyorgy
The present paper reports the first dynamic image analysis-based feedback control of continuous twin-screw wet granulation process. Granulation of the blend of lactose and starch was selected as a model process. The size and size distribution of the obtained particles were successfully monitored...

In-line particle size measurement based on image analysis in a fully continuous granule manufacturing line for rapid process understanding and development
Contributor(s):: Madarász, Lajos, Köte, Ákos, Hambalkó, Bence, Csorba, Kristóf, Kovács, Viktor, Lengyel, László, Marosi, Györgya, Farkas, Attilaa, Nagy, Zsombor Kristóf, Domokos, András
The present paper serves as a demonstration how an in-line PAT tool can be used for rapid and efficient process development in a fully continuous powder to granule line consisting of an interconnected twin-screw wet granulator, vibrational fluid bed dryer, and a regranulating mill. A new method...
