Rotary dryer for cassava dregs‏

Time:2014年07月06日      Hits:

In fact. if we use the traditional rotary drum dryer to dry the cassava dregs, as the evaporate rate is very low, it also means that in order to evaporate same quantity water into water vapor, it will need much more heat, then need to burn much more coal to generate the heat. In one word, it will need much more coal to generate more heat to dry the cassava dregs, but much of the heat is wasted.

According to the special features of the cassava dregs and our past successful and unsuccessful actual experience, our design of the cassava dregs drying system is very different from the traditional rotary drum dryer:

1- Our cassava dregs dryer's inner structure is designed specially according to the features of the cassava dregs.
(Please kindly note that also seen from the surface all the drum dryer are similar, but the inner structure is very important factors to influence the work performance of the drum dryer.)

2- According to the features of the cassava dregs, we dry the wet cassava dregs by two steps.

A. As in high temperature, the wet cassava dregs is very sticky and very easy to become lump, here the special inner structure of the cassava dregs rotary dryer machine help to make the wet cassava dregs as loosened as possible, and to increase the contact area between the wet cassava dregs and hot air as much as possible, thus in the first dryer, much of the humidity is evaporated into water vapor quickly.

As you see, here we can take " use sunshine to dry the wet clothes" as sample, If we do not unfold the wet clothes, and just put the wet clothes into a lump of clothes under the sunshine, then to compare with the wet clothes which is unfolded under the sunshine. I suppose that it is clear that the unfolded wet clothes will get dry more quickly as the contact area between the sunshine and unfolded wet clothes are much more, and thus the heat exchange efficiency is much more high. 

B. After being dried by the first dryer, much of the humidity of the cassava dregs has been evaporated into water vapor, then the semi-dry cassava dregs goes into the second multi pass cassava dregs rotary drum dryer. In the multi pass rotary drum dryer, the semi-dry cassava dregs pass through the rotary drum three times, and come to the high temperature zone two times. Thus it has several advantages: 

a. The heat exchange efficiency is much more high as the cassava dregs come to the high temperature zone two times.

b. The coal consumption will be lower than the traditional rotary drum dryer;

c. The drying time is much more long as the cassava dregs need to pass through the drum three times, and thus the drying effect is much more better.

C. What is more, as we divide the drying system into two steps,between the two types of dryer, there are also several sets screw conveyor, belt conveyor, etc, thus means that the cassava dregs
needs pass through much more longer distance, during the transportation on the screw conveyor and belt conveyor, also some of the humidity of cassava dregs will evaporate.

In one word, the design of the cassava dregs drying system should be according to actual special features of the raw material, only in this way we can get better work performance of the cassava dregs drying system
