SPRAY DRYER DESIGN CONSIDERATIONS

SPRAY DRYER DESIGN CONSIDERATIONS

spray dryer design considerations The most important variables in the design of a spray dryer are the evaporation rate and the required particle size distribution of the product. The evaporation rate and the dryer ΔT (inlet air temperature minus the outlet air temperature) dictates the amount of drying air needed, which dictates the sizing and cost of almost all of the system components.
