How do you get starch from cassava?

Date:Aug 18, 2021/ FAQ/ Chat online/ Technical support
In general, you can get starch from cassava either by hand processing or by machine processing. Both ways have the same cassava starch production process: cleaning, washing, crushing, separating, concentrating, dehydrating and drying. Now more people choose the machine processing way because of its high work efficiency and economic benefits.So in the following, let Jinrui, a professional, introduce how to get starch from cassava in detail combined with the needed machine.

First step: cleaning

First of all, using the dry sieve to remove the dirt, sand, small stones, weeds and other impurities on the surface of cassava.

Second step: washing

Then using paddle washing machine to make the cassava washing completely and eliminate sand and mud effectively.

Third step: crushing

After washing, using cutting machine and rasper to crush the cassava into cassava slurry. This step is extremely important, which can crush cassava to the maximum extent and free the binding starch, which is the key step to improve the yield of cassava starch.

Fourth step: separating

Using centrifuge sieve to separate the fiber and starch slurry, and then using fine fiber sieve to separate small fiber further.

Fifth step: concentrating

In concentrating step, using hydrocyclone station to remove fiber, protein and cell sap out of starch milk to concentrate and delicate scrubbing starch milk.

Sixth step: dehydrating

Using peeler centrifuge to make the solid-liquid separation. That’s the dehydration step of starch milk, after this step, you can get the wet cassava starch. Peeler centrifuge can shorten the dehydrating time, increase production capacity by 50% and decrease moisture content to 36.5%.

Seventh step: drying

Using flash dryer to dry the wet cassava starch into final cassava starch product. Flash dryer is equipped with special negative pressure system and cooling system, which can not only control the loss of cassava starch, but also guarantee the moisture uniformity of the finished starch.
