The drying air is drawn from the atmosphere via a filter by a supply fan and is passed through the air heater to the air disperser. The atomized droplets meet the hot air and the evaporation takes place, while cooling of the air happen simultaneously. In Spray Drier, after the spray is dried in the drying chamber, the majority of the dried product falls to the bottom of the chamber and enters to a pneumatic conveying and cooling system. The fines, which are the particles with a small diameter, will remain in the air, and it is therefore necessary to pass the air through cyclones to separate the fines. The instrumentation comprises indication of the temperature of the inlet and outlet air, as well as automatic control of the inlet temperature by altering the steam pressure, amount of oil or gas to the air heater, and automatic control of the outlet temperature by altering the amount of feed pumped to the atomizing device.
