	A peristaltic pump delivers liquid from the sample container to the 2 fluid nozzle mounted on the drying chamber. Compressed air from the inbuilt compressor is also supplied to the nozzle, resulting in atomization of the liquid into a fine spray. Air from the blower is heated by an electrical air heater and blown through the drying chamber. Due to the large surface area, drying is very rapid, resulting in a sharp drop in temperature. The dry powder particles are separated from the air in the cyclone separator and collected in the glass collection bottle. The exhaust air is directed through a flexible ss hose into the atmosphere. A bag filter can be provided for secondary powder collection.		A peristaltic pump delivers liquid from the sample container to the 2 fluid nozzle mounted on the drying chamber.
