With this equipment, different nozzle sizes are available to disperse the liquide into fine droplets, which are dried quickly and gently in the drying chamber. The generated powder is trained by the aspiration into the cyclone which separates the particles to the gaz.

For organic solvents, and explosive materials, the spray-dryer operates as a closed-loop system, with a condensation system for solvents vapour and a security system for gas detection).
