Conventional spray dryers are known by their high capital and operating costs. Furthermore, low air inlet temperatures and small gas-solid slip velocities limited by gravity leads to low drying rates. In order to develop a commercially viable alternative spray drying technology, a high drying rate in a smaller volume must be achieved. In this study, the possibility of spray drying in a novel multi-zone vortex chamber is investigated using CFD tools. High-G fluidization in vortex chambers leads to intensification of interfacial heat, mass and momentum transfers. Additionally, due to small particle residence times, high air inlet temperatures can be employed that further enhances the drying rates.
