Description of flash drying system

Flash drying system is the ideal equipment for tapioca starch production. Starch dried by this equipment features in clean appearance, glossy luster, smooth powder, and stable moisture while wheat gluten features in high water absoption,  excellent activity and original flavor. 
 
Flash drying system can be designed and produced based on customers' requests on space and warehouse, which is convenient for installation, operation and maintenance. 
 
Air speed in this flash drying system is continuously changed because of different section diameters of pulse tubes, therefore, heat transfer coefficient is high and mass materials can be dried well. 
 
This equipment features in simple structure, easy operation, low investment, as well as compactness.

Working principle of flash drying system
 
Sludge, powder and granular material are in the state of suspension under the effect of high-speed hot air in this tapioca starch production. As flow speed is high, the wet tapioca starch particles suspended in air, the heat transfer surface and heat transfer coefficient of gas-solid is high, and drying time is short (most of the dry material less than 2 seconds), it is particularly suitable for drying of heat sensitive materials.

During the drying process, clean the air heater through the cold air from the wet starch after delivering the transport auger feeder into the air duct by the young wet starch mixture, are instantly dry, dry starch cyclone, discharging auger off air control exhaust, emissions into the atmosphere by the fan.
 
The machine can be controlled, both manual and automatic operation. When it is by automatic control, the exhaust gas temperature of automatic measure by water controlled will send back the signal to the previous feeding adjustable motor. By this way, the feeding capacity can be controlled. Also the output moisture content of tapioca starch production will be ensured.
