The present study reports experimental results concerning the characterization of powdered-material fluidised-bed drying processes. A number of test were carried out in a Lexan® lab-scale fluidised bed with solids selected to effectively surrogate powders of interest in various industrial applications. In particular, pharmaceuticals and adsorption pellets manufactures were of interest. The effects of the temperature and the flow rate of the fluidising gas on the granulation issues were assessed. Experimental results were further worked out to highlight the effects of inlet air temperature and velocity on process thermal efficiency. Bed material was characterized to assess the modifications of the population of agglomerates as a function of the operating conditions.

Abstract

The present study reports experimental results concerning the characterization of powdered-material fluidised-bed drying processes. A number of test were carried out in a Lexan® lab-scale fluidised bed with solids selected to effectively surrogate powders of interest in various industrial applications. In particular, pharmaceuticals and adsorption pellets manufactures were of interest. The effects of the temperature and the flow rate of the fluidising gas on the granulation issues were assessed. Experimental results were further worked out to highlight the effects of inlet air temperature and velocity on process thermal efficiency. Bed material was characterized to assess the modifications of the population of agglomerates as a function of the operating conditions.
