	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.

 ==Spin Flash Dryers==
-If the wet cake is a paste or sludge, swirl flash  dryer is the most suited for drying application. The dryer is fitted  with a mechanical agitator which helps to disperse the wet cake without  any need for back mixing of the dry powder. the feeding system  includes a feed tank with agitator and a screw feeder for feeding into  the drying unit. The heart of drying process is cylindrical drying  chamber, where the drying air enters the air distributor. The tangential  air distributor of special design introduces the air as an intense  swirl flow. the simple spin flash dryer is designed to handle  materials that can be suspended directly in air. The drying process  usually is completed in 0. 5 - 2 sees, and the final moisture is  generally in the constant rate drying zone. Various types of spin flash  dryers designs are available based on uniform / non uniform particle  size of the feed / product. the feeding of cake is through  specially designed paddle mixer / screw conveyor with / without rotary  injector depending on rheology of feed material. For difficult to handle  feed materials part of dried powder can be re-cycled. Spin flash dryers  are suited for filter cakes, semi dried powders.
