2.Washing:After cleaning, materials are transported into sweet potato washing unit. Rotary washing machine is a widely used washing machine for how to extract starch from sweet potato. It can effectively avoid the breaking of sweet potatoes in the washing process, so the starch in sweet potatoes can be retained to the maximum extent and the utilization rate is higher.

3.Cutting: Due to the big size of sweet potato, it will be better to cut it into small piece before crushing process for how to extract starch from sweet potato. The cutting machine is used for this purpose.

4.Grinding: After cutting, the sweet potato is transported into rasper for crushing by screw feeder. As an important machine for how to extract starch from sweet potato, rasper is sweet potato starch machine mainly used for destroying the tissue structure of sweet potatoes so that the small starch particles can be separated from the roots.

5.Separating: The crushed sweet potato slurry includes fibers, protein, cell sap and so on. The machines for how to extract starch from sweet potato for separating process is centrifuge sieve and fine fiber sieve. By utilizing the high speed centrifugal force, centrifuge sieve can effectively separate fiber from starch. The fine fiber sieve is a low speed centrifugal machine. It mainly remove small fibers from starch to further purify the starch slurry.

6.Desanding: According to the principle of specific gravity separation, the starch milk was pumped into the swirl sand separator by pressure pump for how to extract starch from sweet potato. The function of desander is to remove the fine sand particles in the starch slurry, so as to further improve the quality of starch.

7.Concentration and refining: Hydrocyclone station is also an important machine for how to extract starch from sweet potato. It is mainly used for the concentration and refining of starch milk.  Meanwhile, it can remove the protein and cell sap which can further improve the starch quality.

8.Dewatering:  Vacuum filter is a extensively used dewatering machine which is mainly for reducing the water content of starch milk for how to extract starch from sweet potato. After dewatering, the water content in starch milk is 38%-40%. DOING vacuum filter can achieve continuous automatic production, which ensures a cleaning production environment.

9.Drying and packing: After dewatering, the wet starch is transported to the flash dryer for drying. The flash dryer takes use of the negative press principle to dry the wet starch which can effectively control the loss of the starch.  And the last machine for how to extract starch from sweet potato is semi-automatic packaging machine. It can save labors for the factory.
