Agitated Swirl Flash Dryer with Mono Screw Feeder

In Agitated Swirl Flash Dryers, the wet feed is fed into the dryer housing by suitable feeding mechanism above the rotating swirl agitator. The hot air / gas stream is also admitted in the drying duct through specially designed distributor, admitting the air in swirling fashion. The material remains in agitated bed & dried material gets carried forward & separated in the Cyclones or bag filters. Some applications require pre-conditioning of feed by back-mixing of dry product.
