Optimization of Coating Uniformity Using Modified Bio-Polymer in a Tangential Fluidized Bed Coater

Experimental Study of Coating in a Bottom Sprayed Fluidized Bed

Several investigations have been devoted towards understanding the coating process in fluidized beds. Most of these studies focused on spraying liquid droplets over the bed. However, due to the complexity of these systems, more investigations are still required to quantify the effect of operating conditions on the coating criteria. The present work aims at fundamentally understanding and pr...

Mapping the Droplet Drying Phenomena within a Fluidized Bed Coater as a Prediction Tool for Coating Qualities

For a high coating quality, agglomeration and excessive evaporation of the coating droplets during fluidized bed coating process should be avoided (1-3). This means that the coating process can often only be performed within a narrow operating window. Consequently, the selection of the process conditions and the process control are delicate steps to assure a good coating quality. In spite of be...

Investigation of the Effect of Coating Time on the Inter-tablet Coating Uniformity, Using a Bohle Lab Coater

Film Coating of Nifedipine Extended Release Pellets in a Fluid Bed Coater with a Wurster Insert

The objective of this work was to study the coating process of nifedipine extended release pellets using Opadry and Opadry II, in a fluid bed coater with a Wurster insert. The coating process was studied using a complete experimental design of two factors at two levels for each polymer. The variables studied were the inlet air temperature and the coating suspension flow rate. The agglomerate fr...
