How to extract starch from cassava?

The process of to extract starch from cassava is operated by automatically cassava starch production line：cleaning, washing, grinding, separating, desanding, concentration and refining, dehydration and drying of cassava raw materials.

1. Cassava cleaning: 
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: 
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 cassava starch processing machine adopts the countercurrent washing principle so that the material can be washed completed and thoroughly in cassava starch production process.

3. Cassava grinding:
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.Rasper is a high efficient machine with a breakage rate more than 94%. 

4. Starch slurry separation:
Separation is important for how is starch obtained from cassava root for it also determines the starch extraction rate. Henan Jinrui 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: 
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: 
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%.

The above is the entire description of how is starch obtained from cassava root. Doing Holdings-Henan Jinrui is a comprehensive manufacture of cassava starch processing machine integrating R&D, production and trade. Welcome to contact our engineer for how to extract starch from cassava.
