Visualization and understanding of the granulation liquid mixing and distribution during continuous twin screw granulation using NIR chemical imaging
Contributor(s):: Vercruysse, Jurgen, Toiviainen, Maunu, Fonteyne, Margot, Helkimo, Niko, Ketolainen, Jarkko, Juuti, Mikko, Delaet, Urbain, Van Assche, Ivo, Remon, Jean Paul, Vervaet, Chris, De Beer, Thomas
Over the last decade, there has been increased interest in the application of twin screw granulation as a continuous wet granulation technique for pharmaceutical drug formulations. However, the mixing of granulation liquid and powder material during the short residence time inside the screw...

TPLS as predictive platform for twin-screw wet granulation process and formulation development
Contributor(s):: Ryckaert, A., Van Hauwermeiren, D., Dhondt, J., De Man, A., Funke, A., Djuric, D., Vervaet, C., Nopens, I., De Beer, T.
In recent years, the interest in continuous manufacturing techniques, such as twin-screw wet granulation, has increased. However, the understanding of the influence of the combination of raw material properties and process settings upon the granule quality attributes is still limited. In this...

The Influence of Equipment Design and Process Parameters on Granule Breakage in a Semi-Continuous Fluid Bed Dryer after Continuous Twin-Screw Wet Granulation
Contributor(s):: Ryckaert, Alexander, Ghijs, Michael, Portier, Christoph, Djuric, Dejan, Funke, Adrian, Vervaet, Chris, De Beer, Thomas
The drying unit of a continuous from-powder-to-tablet manufacturing line based on twin-screw granulation (TSG) is a crucial intermediate process step to achieve the desired tablet quality. Understanding the size reduction of pharmaceutical granules before, during, and after the fluid bed drying...

Pharmaceutical application of multivariate modelling techniques: a review on the manufacturing of tablets
Contributor(s):: Shi, Guolin, Lin, Longfei, Liu, Yuling, Chen, Gongsen, Luo, Yuting, Wu, Yanqiu, Li, Hui
The tablet manufacturing process is a complex system, especially in continuous manufacturing (CM). It includes multiple unit operations, such as mixing, granulation, and tableting. In tablet manufacturing, critical quality attributes are influenced by multiple factorial relationships between...

Laboratory of the future: a modular flow platform with multiple integrated PAT tools for multistep reactions
Contributor(s):: Sagmeister, Peter, Hone, Christopher, Williams, Jason D, Kappe, Oliver
Currently, the monitoring of multistep continuous flow processes by multiple analytical sources is still seen as a resource intensive and specialized activity. In this article, the coupling of a modular microreactor platform with real-time monitoring by inline IR and NMR, in addition to online...

Impact of screw configuration on the particle size distribution of granules produced by twin screw granulation
Contributor(s):: Vercruysse, J, Burggraeve, A., Fonteyne, M., Cappuyns, P., Delaet, U., Van Assche, I., De Beer, T., Remon, J. P., Vervaet, C.
Twin screw granulation (TSG) has been reported by different Research Article groups as an attractive technology for continuous wet granulation. However, in contrast to fluidized bed granulation, granules produced via this technique typically have a wide and multimodal particle size distribution...

Breakage and drying behaviour of granules in a continuous fluid bed dryer: Influence of process parameters and wet granule transfer
Contributor(s):: De Leersnyder, F., Vanhoorne, V., Bekaert, H., Vercruysse, J., Ghijs, M., Bostijn, N., Verstraeten, M., Cappuyns, P., Van Assche, I., Vander Heyden, Y., Ziemons, E., Remon, J. P., Nopens, I., Vervaet, C., De Beer, T.
Although twin screw granulation has already been widely studied in recent years, only few studies addressed the subsequent continuous drying which is required after wet granulation and still suffers from a lack of detailed understanding. The latter is important for optimisation and control and,...
