Abstract The present research work deals with drying of particulate solids in inductively heated fluidized bed. Capillary-porous and non-porous solids are dried by inductive and convective (benchmark experiments) heating. The influence of both heating types and test materials on the drying rate and the product moisture content is discussed. The conducted drying trials present very similar drying rates and product moisture contents under the same drying conditions by both energy input methods in fluidized beds. Moreover, it was demonstrated that this novel method for energy input in fluidized beds allows rapid heating and cooling and therefore enables considerably more controllable temperature profiles. In this way, the costly and time consuming start-up processes in batchwise fluidized bed processing can be shorten. This study therefore clearly points out the enormes potential of inductive energy input in fluidized beds.
