Flash dryer

The introduction of flash dryer

Flash dryer not only applies to various kinds of potato starch drying, but also for corn and wheat starch drying. And it is also suitable for drying of other heat sensitive power or flake materials that need fast drying. Flash dryer makes use of high speed hot air flow to suspend the wet starch in the air. And in the process of airflow transportation, the starch drying process is completed. It has the features of large heat transfer area, short drying time and so on. In the cassava starch processing industry, flash dryer is an ideal cassava starch drying machine. Starch dried by this equipment features in clean appearance, glossy luster, smooth powder, and stable moisture.

The structure and working principle of flash dryer

The flash dryer machine is composed of air filter, air pre-heater, hopper, powder thrower, dry air pipe, cyclone separator, blower, wind shutoff device and other equipment as well as temperature measurement and speed measurement device.

The working principle of this cassava starch drying machine is negative press drying.The wet starch enters into the flash dryer pipe, in the effect of high speed hot air flow,  rotating along the hot pipe wall. The rotating movement aggravates the continuous rolling of the starch in the pipe which make the hot air and starch fully contacted.  Under negative pressure in the pipe system, the heat and mass exchange between the hot air flow and the cassava starch suspended in the hot air pipe. After the water in the wet starch evaporates, it is carried away by the hot air. Then the dried starch passes through the cyclone separator and enters into the next machine. Due to the fast speed and large heat transfer area, the whole drying process is completed in an instant.

The features of flash dryer

1.The technical parameters of the whole process is strictly controlled according to the theoretical calculation which ensures the physical and chemical index of the of final starch after drying.

2.The parts in contact with material of this cassava starch drying machine is made of stainless steel which ensures high standards of final product.

3.The negative press in the whole system effectively controls the loss of starch and purifies the working environment.

4.There is a special cooling system which guarantees the moisture uniformity of the finished starch and the long distance transportation.

5.The short time of materials retention in the dryer tower and high heat-exchange rate could dry starch instantly.

6.Doing Company can design and produce the flash dryer  based on customers' requests on space and warehouse.
