Agitated Swirl Flash Dryer

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.
