Cassava Dregs Dryer Design

Time:2014年06月18日      Hits:

In this article Sunco Machinery engineer will introduce how to design the Cassava Dregs Dryer.  As the wet cassava dregs will has mellow effect ripening in the high temperature during drying process, the cassava dregs then will be very sticky and it is very easy to become lumps which is very bad for the drying efficiency of the cassava dregs dryer machine


In order to solve this problem, we use different type cassava dregs drying machine to dry the wet cassava dregs in two steps:

A. Use the paddle type dryer to dry the wet cassava dregs firstly. 

On the inner wall of the paddle type cassava dregs dryer there are many welded guide plate, also there is one paddle type shaft which is installed in the center of the dryer drum. 

When the paddle type dryer is rotating, the paddle type shaft also is rotating quickly. The guide plate and the high rotation speed paddle type shaft make the wet cassava dregs more loosened, and thus increase the contact area between the wet cassava dregs and hot air as much as possible, and then increase the heat exchange efficiency between the wet cassava dregs and hot air as much as possible.

As a result, many of the humidity of the wet cassava dregs is evaporated into water vapor in the paddle type dryer. 

When the cassava dregs leaves the paddle type dryer, and then goes into the multi pass rotary dryer, the cassava dregs is not so sticky, and then the work performance of the multi pass rotary dryer will be much better.

Please note that the paddle type dryer mainly is used to solve the cassava dregs lumps problem.

B. Use the multi pass rotary dryer to dry the cassava dregs again. 

Supplying the room for drying the cassava dregs. The cassava dregs goes through the drum three times, and come to the high temperature zone two times. Thus, it not only increase much of the drying time, but also use the heat much more sufficiently. 

After being dried by the multi pass rotary cassava dregs dryer, finally we get 3.5 tons 13%-15% dried cassava dregs.
