Rotary-stream fluidized bed drying is the combination of fluidized bed drying and pneumatic drying. Both non-viscous and viscous materials and even sticky paste can be dried successfully with this technique. The material being processed is turned to powder or granular product of controlled homogeneous in one treatment and no further pulverization is necessary. Correlation of Eu vs Re and Nu vs Re were obtained from hydrodynamic experiment and drying experiment respectively.
