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.

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.
