High quality sweet potato starch processing line

Introduction of Sweet Potato Starch Production Line

Washing &Crushing Section in sweet potato starch production line
The sweet potato, the material is sent to cage washer through scrape board to get the result of decontamination, cleaning and peeling . Then through a paddle-washing slot, material is sent to crash section.
We adopt the rasper to crash materials. Compared with traditional crasher, it has the large capacity, high starch dissociation degree features, which are essential to get high starch recovery.

Milling and grinding section in sweet potato starch production line
Grinding clean potato root into cassava slurry to make it easy dewatering and drying.

Concentrating Section in sweet potato starch production line
The crashed material is sent to centrifugal sieve through pump to extract starch and separate potato residues.Centrifugal sieve group are 4 or 5 stages, the front stages is to extract starch and the last stage is to dewater the potato  residues. The whole stage adopts countercurrent washing to get the best results and saving water.

De-hydrating section  in sweet potato starch production line
Sending the fine slurry to dewatering machine to remove the moisture inside the slurry, and then send it to the air dryer.
Compared with other starch, it is more suitable for potato starch to dewater by vacuum filter. Moisture content of
dewatered starch is 38~40%. Wet starch is sent to drying system through belt conveyer.

Drying section in sweet potato starch production line
Drying the dewatered cassava flour in the air dryer to get dry product.
Dried starch reaches sieving system. High efficiency cooling starch sifter is used to cool starch and get the best starch.
