The '''Flash Dryers''' offer an effective and efficient method of removal of  surface or on  bound moisture from a feed product. Flash dryers are  pneumatic driers  having very low residence time within the equipment,  thus flashing off  the moisture from the feed. They are used for  efficient drying of moist  powders. Slurry, filter cakes, granules, etc.  They operate on varying  throughput rates from few hundred kilograms per  hour to hundreds of  tons per hour. Low temperature dehumidified air  could be used for heat sensitive products to hot gases with temperature  up to 500 - 600 deg.  C. For temperature resistant products. Flash dryers  comprises of the  feeding section normally a screw feeder, rotary valve,  vibratory  feeder, etc. Which feeds the wet product in a controlled  fashion into  the throat of the flash drier, where it is mixed with hot air produced  by a hot air generator or heat exchanger.
