Spray dryer including fluidized spray dryer, single stage fluidized spray dryers are used for producing large particles. Fluidized spray dryer offers particle size of dried material from 50-250 microns.

Single stage fluidized spray dryers offer particle sizes of dried material from 50-250 microns. For producing large particles fluidized spray dryers are employed. The atomization of the feed solution is done to produce large droplets and the drying in the first stage is done keeping the moisture content of the powder relatively high.
