The full automatic sweet potato starch making machine inclueds remove stone—washing-- steam peeling-- dry brush peeling-- sorting and pruning--slicing--blanching and cooling-- cooking and mashing—transport—unifying materials—making flakes—scraping--packing.

Washing &Crushing Section
potato, the material is sent to cage washer through scrape board to get the result of decontamination, cleaningand peeling .Then through a paddle-washing slot, material is sent to crash section.

Milling and grinding section
Grinding clean potato root into cassava slurry to make it easy dewatering and drying.

Concentrating Section
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.

De-hydrating section  
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%.

Drying section
Drying the dewatered cassava flour in the air dryer to get dry product.
