1. Cleaning and washing: The sweet potato is firstly be cleaned in dry sieve to remove the sand, weed and other dirty materials for how is sweet potato starch made. The dry sieve is a high effective washing machine which will not damage the raw material. And the washed sweet potato is transported into rotary washing machine to further wash the attached impurities, such as soil and sand. This sweet potato starch machine adopts countercurrent washing principle which can ensure the raw material be washed cleanly and thoroughly.
2. Cutting and crushing: After washing, the sweet potato is firstly cut into small pieces so that it can be crushed fully. After cutting, the sweet potato is crushed into slurry for further processing. Crushing plays an important role for how is sweet potato starch made for it determines the starch yield. DOING rasper is a high efficient sweet potato starch machine with high rasping coefficient and high extraction rate.

3.Starch and residue separating: After crushing, the sweet potato slurry includes many fiber, protein, cell sap and other impurities for how is sweet potato starch made. They need to be separated from starch in extraction of starch from sweet potato. And in this process, centrifuge sieve and fine fiber sieve are mainly used sweet potato starch machine. The centrifuge is used to separate the fiber and starch by using the high speed centrifugal force. While the fine fiber sieve is low speed sieve which is mainly used for the separation of the small fiber. Normally in order to separate the impurities better, the centrifugal process will repeat several times.
4. Concentration and refining: After the separation section, the sweet potato slurry need to be further refined for how is sweet potato starch made. This process mainly removes the protein, fine fiber and cell sap. In this process, the mainly used sweet potato starch machine for the extraction of starch from sweet potato is hydrocyclone station. A full hydrocyclone technology includes the concentration, refining and recycling.
5. Starch milk dehydration: In the process of how is sweet potato starch made, the purpose of dehydration is to reduce the water content of sweet potato milk. And vacuum filter is mainly used sweet potato starch machine for this process. After dehydration by DOING vacuum filter, the moisture content of wet starch is around 38%.

6. Drying and packing: The final process about how is sweet potato starch made is the drying and packing. The dehydrated starch cake is transported to the feed inlet of the flash dryer through the conveyor belt and enters the hoist through the feeder. The wet starch is heated by the high speed hot air and the water is evaporated. Finally, the dried starch is then transported to sweet potato starch machine for packaging.
The whole production process for how is sweet potato starch made adopts Doing Company's new automatic sweet potato starch production line, from fresh sweet potato to starch products are all automated production, high quality, high efficiency, energy saving and labor saving.
