How is starch obtained from cassava root ?

The cassava starch production line of Doing Company adopts the wet processing technology of starch production without any additives. The process of how is starch obtained from cassava root is operated automatically from the whole process of cleaning, washing, grinding, separating, desanding, concentration and refining, dehydration and drying of raw materials.
Cassava & cassava starch


The following is the detail introduction of how is starch obtained from cassava root
1. Cassava cleaning unit:
The dry sieve is the firstly used for how is starch obtained from cassava root. It meanly remove the dirt, stand, small stones, weeds and other impurities on the surface of the cassava.

2. Cassava washing unit:
Paddle washing machine is the most widely used washing machine for how is starch obtained from cassava root whose main function is to further wash the attached dirt, mud, sand, ect. This machine adopts the countercurrent washing principle so that the material can be washed completed and thoroughly in cassava starch production process.

3. Cassava grinding unit:

The washed cassava is then transported into grinding machine by screw feeder for how is starch obtained from cassava root. This is the vital process in cassava starch processing line. The purpose of this process is to grind cassava into starch so as to releasse starch from cell wall. The breakage rate and extraction rate of the machine determines the final cassava starch yield. DOING rasper is a high efficient machine with a breakage rate more than 94%.

4. Starch slurry separation unit:
Separation is important for how is starch obtained from cassava root for it also determines the starch extraction rate. DOING use multi stage centrifuge sieve for separating fiber from starch in cassava starch processing plant. And fine fiber sieve is added for further removing the fine fibers out of starch slurry.

5. Cassava starch concentration and refining unit:
The hydrocyclone station is the next machine used for how is starch obtained from cassava root. The main purpose of this machine for how is tapioca made from cassava is to remove the fiber, protein and cell sap. The full hydrocyclone technology includes the concentration, refining and recycling of cassava starch.

6.Cassava dewatering unit:
Cassava dewater machine is mainly used for reduce the water content of cassava starch. The most widely used dewatering machine for how is starch obtained from cassava root is peeler centrifuge which is a continous operation machine. Afte the dewatering process, the water content of wet starch is about 38%.

7. Starch drying unit:

For drying process, flash dryer is the drying machine for the process of how is starch obtained from cassava root. The whole process time of air drying is completed in an instant, so the internal moisture of the starch granules is dried before gelatinized, and this process consists of heat transfer and mass transfer.

The above is the entire description of how is starch obtained from cassava root. Doing Company is a comprehensive company integrating R&D, production and trade. Welcome to contact us  DOING engineer for how is starch obtained from cassava root.
