Automatic potato starch processing technology

Potato starch production line adopts the wet processing technology of starch production, and no additives are added in the whole production process.The potato starch processing technology includes the following:
Potato cleaning and washing-crushing-separating-desanding and refining-dewatering-drying and packing

1.Pretreatment of potato process
Cleaning and washing: For potato starch processing technology, the first step is cleaning. Cleaning process is for removing the stone, seed and dirt of sweet potato. Dry sieve is mainly used for this purpose. Then the potato need to be washed in rotary washing machine. After the two process, the sweet potato is completely and thoroughly washed.
2.potato starch extraction process
Cutting and rasping: After washing in potato starch production plant, the potato is firstly cut into small pieces so that it can be crushed fully in potato starch processing technology. After cutting, the potato is crushed into slurry for further processing. Crushing plays an important role in the potato starch processing technology for it determines the starch yield. DOING rasper is a high efficient machine with high rasping coefficient and high extraction rate.

3.potato starch separation and refining process
a. Separating and desanding: After crushing, the fiber, protein, cell sap and other materials are released from cell wall. Therefore the separating is needed to separate starch from fiber and other impurities for potato starch processing technology. Separating process mainly remove fiber from starch. Centrifuge sieve is the mainly used potato starch processing machine.

b. Concentration and refining: The starch slurry from the desander unit is transferred to the multi-stage concentration and refining unit. For the potato starch processing technology, hydrocyclone station is mainly used for this process. The process water is pumped in from the other end of the hydrocyclone station to wash the starch in a countercurrent way. Usually a full process includes the concentration, recycling and refining of starch milk.
4.Starch dehydrating and drying process
a. Dehydrating: The dehydrating is used to reduce the water content of starch milk so that is can be dried in the potato starch processing technology. Vacuum filter is a potato starch processing machine take use of negative pressure to achieve the purpose of dehydrating. After dehydrating,  the filter cake is scraped down by the scraper and transported into the feed hopper of the flash dryer with food-grade conveyor belt.

b. Drying and packing: The final process for potato starch processing technology 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 semi-automatic packaging machine and packaged into finished products.
The whole potato starch processing technology adopts the company's new automatic starch processing production line, from fresh potato to starch products are all automated production, high quality, high efficiency, energy saving and labor saving.
