Due to maintain the integrity of potato granules as much as possibly in the produce process the potato granules and flakes after watering have the nutrition, flavor and taste of cooked potatoes. Potato starch is only one of many ingredients of potato. So potato starch does not have the nutrition, flavor and taster of potatoes.
 

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.

 

The Fully Automatic Sweet Potato Starch Product Line processing technology is describing briefly as following: raw material washing, peeling off, general crushing, fine crushing, separating of residue and starch slurry, starch slurry refining, dewatering, airflow drying, dressing and 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.

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

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. The whole stage adopts countercurrent washing to get the best results and saving water.

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%. Wet starch is sent to drying system through belt conveyer. 
 

Drying section

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 .
