1.Cassava choosing process: The quality of the raw cassava has an important influence on the starch quality, therefore the cassava choosing process is the first step towards a high quality cassava starch product. If the chosen cassava is less than 10 months, the cassava starch extraction rate will be very low. While the cassava more than 24 months old cassava has been qualitative which caused great difficulties to broken and grinding in cassava starch manufacturing process. Thus it not only resulted in the reduction of the extraction rate but also increase the  cost which is also not a good choice. Therefore it will be better to choose raw cassava between 10-12 month.

2.Cassava cleaning process: The most wildly used cassava cleaning machine is called dry sieve in cassava starch manufacturing process. This cassava starch processing machinery is normally used in the first step in cassava production line. It is mainly used for removing the sand, soil and other debris.

3. Cassava washing process: Paddle washing machine is the most widely used cassava washing machine in cassava starch manufacturing process 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.

4. Cassava grinding process: The washed cassava is then transported into grinding machine by screw feeder. 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 in cassava starch manufacturing process. DOING rasper is a high efficient machine with a breakage rate more than 94%.

5. Concentrating process: Starch separating is another key unit for how to extract starch from cassava which has an important effect on the extraction rate of cassava starch in cassava starch manufacturing process. The good centrifuge sieve and processing technology can extract the free starch from the cassava cells. After every processing, it need take samples of the starch slurry to test the starch content. During the repeat process, the water can be recycled which is a good way to reduce the water consumption.

6. Cassava desanding process: The main function of the cassava desander is to remove sand out of starch slurry in cassava starch manufacturing process. We all know that the sand content of cassava is high. If the sand is not removed, it will influence the taste of the final products. Therefore the desander machine is a necessary cassava starch extraction machine.

7. Concentration and refining process: After desanding, the cassava starch enters into hydrocyclone station. This process is mainly used for separate the fiber, protein and cell sap from starch. In cassava starch manufacturing process, DOING full hydrocyclone technology can achieve the concentration, recycling and refining of cassava milk.

8. Dewatering process: The next step in cassava starch manufacturing process is the dewatering. The dewatering machine by Doing Company is the peeler centrifuge. This touch material is made of high quality stainless steel which ensures high starch quality.

9. Cassava drying process: Flash dryer is the extemsively used cassava drying machine whose main function is to dry the wet starch in cassava starch manufacturing process. The working principle of this machinery is negative press drying which can drying the material within few seconds.
