Product Description
A flash dryer or pneumatic dryer is an industrial continuous and rapid drying system that suspends moist materialssuch as powders granules pastes and slurriesin a hot highvelocity air stream to evaporate moisture within seconds It is widely used in industries like food chemical pharmaceutical and biomass for its efficiency low residence time and high evaporation capacity
This video provides a detailed overview of the working principle of a flash dryer
Key Features and Working Principle
Rapid Process Drying typically occurs in less than 60 seconds which is ideal for heatsensitive materials
Mechanism Wet material is introduced into a highspeed heated air stream often via a venturi or pneumatic feeder immediately reducing moisture content
Particle Suspension The material is conveyed dispersed and dried simultaneously preventing overheating of the product
System Components Usually includes an air heater feeder drying duct cyclone separator and bag filter
