Whole cassava starch processing plant

The whole cassava starch processing plant can be divided into the following units:

Cassava harvest

1 Harvest Unit

Cassava tubers harvested from the ground should first dry and sieve to remove the impurities as much as possible, and then stored in daily designated area.

2 Cassava grinding unit

Firstly, cassava tubers feed into the screw conveyor, during this part, cassava tubers also could be washed by the water sprayed by water pipe. After twice washing of two sets screw conveyors, cassava tubers feed into rasping machine. In order to production line not to stop when changing the saw blade, it should install the second rasping machine.

3 Starch Extraction/Fiber Separation Unit during cassava starch processing plant

The cassava paste after mixing with water then pump into the first level screen, the wet fiber come down from the first screen is pumped into the second, third and the fourth extraction screen, be sent to the fiber dryer dehydration. Wet residue dry matter content after dehydration is 10-12%.

4 Enrichment Unit

Down from extraction process in the first level of cone sieve starch slurry pump into rotary self-cleaning filter. Then starch slurry is concentrated.

Desanding unit

5 Desanding Unit

Starch milk after concentration is sent to a mixing tank, and then starch can use two levels of de-sander expel sand, the sand collected uses butterfly valve to eject.

6 Refined Unit

At this time the starches with 12-14 level cyclone stand to clean, refined. Refined unit automatic work and is equipped with the necessary instruments. Starch slurry concentration after the refined is 35-40%.

7 Fine Fibre Sieve Unit

After the refined overflow contains a lot of protein, salt, sugar, soluble fiber material and fine fibres, transfer them to fine fiber separation screen to extract fine fiber. it can collect with cans so as to use to cleaning in extract unit..

8 Dehydration Unit

After refining from the hydrocyclone, starch slurry flow into the buffer pot, and will be desand by the desanding machine. Then remove moisture through vacuum filter. The wet starch water content after dehydration is 38—40%.

9 Starch Dry Unit

This system is suspension air dry, its characteristic is the product of dry and hot air evenly mixed, suspended airflow drying efficiency is very high, even the product particle size distribution is wide.

After drying the product with high efficiency cyclone to collect, with a low speed screw conveyor discharging. The air through the filter with saturated steam heating and through the fan into the dryer, drying machine of finished with pneumatic conveyor or screw conveyor to cool it. Cooling dry starch collected with two stage cyclone separator and screw conveyor sent to the sieving machine, packaging warehousing after screening. The whole cassava starch processing plant completed.
