From abstract: Wet Granulation is a size enlargement process where powder particles are bonded together using a liquid, which can be poured, sprayed or melted into the powder mass. Granulation is an important processing step in many industries, perhaps most notably in the, pharmaceutical and food industries. Historically, process and product development has taken place on a case by case basis, with significant costly trial and error required. There is now a move forward to take this ‘black art’ approach towards a more science based engineering design methodology, with a view to develop a ‘granulation theory’ and a comprehensive multi-scale model. In order to do this it is necessary to employ various experimental techniques across all the length scales; micro-, meso-, and macro-. Some of the techniques being further developed; such as particle image velocimetry (PIV), High Speed Imaging, Thermal Imaging, X-Ray Tomography, Visual On-line sizing (VOS) and DEM modelling, and their application from drop-powder and drop-granule interaction and evolution of granule structure at the micro-scale, to intra-granulator powder motion and collision rates, binder distribution at the macro-scale, will be introduced.
