β¦ Synopsis
A kinetic model is d e v e l o p e d for t h e drying of solids in fluidized b e d s , assuming a falling rate period following a constant rate period. Experimental d a t a obtained using b a t c h a n d continuous single a n d spiral fluidized b e d s are satisfactorily m a t c h e d with t h e assumed drying kinetics a n d t h e r e s i d e n c e time distribution of solids appropriate for t h e t y p e of dryer.

A sucroselactose-starch granulation was used to study particulate motion and attrition in a fluid bed dryer. There is some classification of material in the dryer as drying proceeds; fine particles are dried faster and become less dense, and the less dry but denser large particles show some (althoug
