A spray dryer is a device used to convert liquids containing dissolved or suspended solids into powder of required specifications by evaporation of liquid with hot air. Spray drying is a highly efficient drying method with possibility to have close control over the particle size, bulk density and moisture content of the dried powder.
Liquid or slurry is pumped into the spray dryer
A nozzle or rotary atomizer converts the liquid into fine mist droplets
Heated air enters the suitably designed drying chamber
Droplets rapidly lose moisture as they fall, turning into powder
Solid dry particles are collected at the bottom of the chamber, are carried by air and separated in cyclone separator, bag filter or wet scrubber
