In Flash Dryer, the wet feed is dispersed into the hot air/gas stream in the drying duct through suitable feed dispersing mechanism. The material gets dried during conveying travel through the drying duct separated in the Cyclones or bag filters. Some applications require preconditioning of feed by back-mixing of a dry product or mixing with oversize particles tapped through particle classifiers installed at suitable locations on the drying duct. AVM offers Customized Flash Drying Systems with a variety of Configurations.
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 a 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 preconditioning of feed by back-mixing of dry product. AVM offers Customized Agitated Swirl Flash Drying Systems with a variety of Configurations.
