Spray dryer consists of a spray chamber and a separating chamber (cyclone separator). They are interconnected by means of a narrow pipe (see Figure 1). An atomizer is fitted at the top of the spray chamber which sprays the feed as droplets. An inlet for hot air (or gas) is present at the top. The entire equipment is made up of stainless steel.
