Overseas Installation Potato Starch Rotary Washer Machines Processing Plan
Rotary drum washer is applied to wash potatoes, cassavas, sweet potatoes and etc. Rotary washer is the washing section machine in starch
processing line and it adopts the principle of countercurrent to clean out mud, sand and small stones effectively.

Advantages of rotary washer machine
1. Combining the latest technology and years’ experience into a whole
2. Adopting method of countercurrent washing, excellent washing result, mud and sand removing.
3. Reasonable feeding structure. The damage rate of raw material is under 1% and this can ensure high starch extraction yield.
4. Compact design, big capacity, energy and water saving
5. Stable operation and rational motor equipped.
Working principle
The washing machine is designed with counter-current washing, that is, the washing water enters the washing machine from the material outlet.
The material enters into the rotating drum and is cleaned in the tumbling collision. Meanwhile, the material's skin is effectively removed. The
cleaned sediment skin falls between the drum and the inner wall of the water tank through the mesh, moves forward under the push of the blades,
and is discharged through the overflow tank.
There are four steps to making starch
1. Cleaning:To remove the stone sand and from the raw material.
2. Crushing :To destroys the fiber structure and makes the starch particles free.
3. Separator:To removing sand ,mud from starch slurry, degreasing, microslag separation, protein separation, washing and concentration of all
kinds of starch and modified starch emulsion.
4. Drying and Packing:To dehydrator the wet starch, sifter and packaged.
