Spin Flash Dryer

Tunnel and cupboard dryers are inherently costly to run, occupy a larger floor space, involve higher number of manual labor and yet the drying rate is slow with much lower thermal efficiency. Compared to this, the FLASH DRYER in its simplest form of mechanical design; is merely a Hot Air Conveyor into which solids, if reasonable free flowing, may be dropped. The material then gets dispersed, thus exposing maximum surface to the drying process. This leads to a very rapid drying rate and the time required is in seconds and not in minutes or hours. Due to the short exposure time and rapid evaporation of water, even though high temperature is employed; the material remains at wet bulb temperature (W.B.T.) until all traces of surface moisture is removed. Thus it is possible to employ high inlet temperature, may be up to 700 C, without affecting the quality of the material, which may even, if it is a heat sensitive one.
