Several spouted bed configurations have been proposed in order to overcome the limitations and disadvantages of the conventional spouted bed (CSB). This paper evaluates the performance of a modified mechanically spouted bed (MMSB) fitted with a helical screw, which was applied in the drying processes of alumina and skimmed milk. In this equipment, the cyclic movement of the solid phase was promoted by the screw and the air was supplied perpendicularly, following the CSB design. The main objective of this study was to analyze the energy performance of the MMSB. The results showed that the MMSB provided a drying process under stable conditions at air velocities lower than the minimum spout velocity, due to inclusion of the helical screw, leading to greater energy efficiency and lower energy consumption.
