(505e) Comparing a Semi-Continuous Tablet Coating Process at Different Scales Using CFD-DEM
AIChE Annual Meeting
Wednesday, October 31, 2018 - 1:54pm to 2:15pm
We developed a computational CFD-DEM model that allows the simulation of the coating process inside the GEA ConsigmaTM coaters including tablet fluid interaction. We will show a model to simulate accurately biconvex tablets including a drag model that takes into account the non-sphericity of the tablets. At the end we will compare two different drum scales of the GEA ConsigmaTM coater (160 mm width and 320 mm width) and compare the scalability of the drum design. The comparison will include the mixing inside the ConsigmaTM coater, as well as the coating performance and the heat transfer during the coating process. Guidance on how to scale between the two tablet coaters will be developed with the help of the simulation results.
