How to make tapioca starch ?

Tapioca starch making plant

Tapioca starch is a fine white powder , similar to corn starch. Tapioca starch is  mainly made by wet milling from the cassava root .

How to make tapioca starch ?

 The whole process of making tapioca starch can be divided into the following steps :

1 Cassava Washing/De-stone step : 

New harvest cassavas from the ground should first clean and wahsing to remove the impurities as much as possible by cassava cleaning machine and cassava washing machine. 

2. Cassava Crushing and Milling step : 

Cassavas feed into crushing and milling machine through belt conveyer to mill cleaned cassava to cassava slurry.

3. Starch Extraction/Fiber Separation step : 

The cassava slurrry after miiling mixed 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 Fine Fibre Sieve strp :

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

5. Desand step :

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 step :

At this time the starches with 18 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%

8 Dehydration step : 

Tapioca starch slurry after hydro cyclone refined, and then pump to vacuum filter for removing moisture . The wet starch water content after dehydration is 38—40%.

9 Starch Dry step : 

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.
