How is sweet potato starch made？

Sweet potato starch is one of the main products of sweet potato processing. But how is sweet potato starch made? Sweet potato starch is normally processed thorough a series of procedure. Doing Company is a professional starch deeply processing equipment manufacturer, we can not only offer you the solution for how is sweet potato starch made, but also provide potato starch processing machine. The production line of how is sweet potato starch made can automatically complete the whole process of cleaning, washing, crushing, rasping, separation, concentration and refinement, dehydration, drying and packaging of sweet potato.
Here are the detail introduction of how is sweet potato starch made
1. Sweet potato cleaning and washing: The sweet potato is firstly be cleaned in dry sieve to remove the sand, weed and other dirty materials. The dry sieve is a high effective cleaning 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 washing machine adopts countercurrent washing principle which can ensure the raw material be washed cleanly and thoroughly.

2. Sweet potato crushing: This is the key process for how is sweet potato starch made. In this process in sweet potato starch production plant, the sweet potato is crushed into slurry. And the bound starch in sweet potato turns to free starch. And the extraction rate of sweet potato determines the final starch yield. DOING rasper is an advanced rasping machine with high rasping rate and high extraction rate.
3. Starch slurry separation: This section is mainly used for separating fiber. The mainly used machine includes centrifuge sieve and fine fiber sieve. The centrifuge sieve is mainly used for removing fiber and fine fiber sieve is for further removing fine fiber. This is also an important procedure for how is sweet potato starch made.

4. Starch slurry concentration and refining section: After the separation section of how is sweet potato starch made, the sweet potato slurry need to be further refined. This process mainly removes the protein, fine fiber and cell sap. In this process, the mainly used machine for the how is sweet potato starch made is hydrocyclone station. A full hydrocyclone technology includes the concentration, refining and recycling.
5. Starch milk dehydration: In this process of how is sweet potato starch made, the purpose of dehydration is to reduce the water content of sweet potato milk. And starch vacuum filter is mainly used for this process. After dehydration by DOING vacuum filter, the moisture content of wet starch is around 38%.

6.Starch drying and packing: The dehydrated starch is then transported into flash dryer for drying in the process of how is sweet potato starch made. The flash dryer takes use of negative pressure principle which effectively controls the loss of the starch and ensures cleaning operation environment.
The equipment produced by Doing Company can complete the whole process from the input of raw materials to the production of finished starch. It can also be customized according to the actual situation and special requirements of users. We provide large, medium and small processing lines and machines for how is sweet potato starch made with various configurations to meet the needs of different customer groups.
