Potato /Sweet Potato Starch Process Machine Starch Flash Dryer

Potato /Sweet Potato Starch Process Machine Starch Flash Dryer

Working Principle:

The flash dryer consists of dry main engine, feeder, heat source device (hot air furnace or steam), air filter, air blower,

cyclone separator, bag filter, and induced draft fan. The hot air tangentially enters the bottom of the dryer and is driven by the agitator to form a powerful rotating wind field. The paste material enters the dryer by the screw feeder. Under the strong action of the high-speed rotating stirring paddle, the material is dispersed under the action of impact, friction and shearing force, the block material is rapidly pulverized, and it is fully contacted with hot air and heated ,and dry. The dehydrated dry material rises with the hot gas flow, and the classification ring intercepts the large particles. The small particles are discharged from the center of the ring to the outside of the dryer, and are recovered by the cyclone separator and the dust collector. The dry material is not dried or the bulk material is subjected to centrifugal force , fell to the bottom and was crushed and dried.

Type of flash dryer :

Description of flash dryer :

Flash dryer is designed by ourselves.The hot air enter into the dryer chamber from the bottom of dryer host, it's going into the dryer chamber by inlet entrance. The rotor at the conical base of the drying chamber fluidity product particles in a drying-efficient hot air flow pattern in which any wet lumps are rapidly disintegrated. Using the heat from the air stream, the material dries as it is conveyed. The product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.
