Sweet potato starch making line machine introduction:
The sweet potato starch 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 in Sweet Potato Starch Making Line :
Sweet 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 in Sweet Potato Starch Making Line :
Grinding clean sweet potato root into sweet potato slurry to make it easy dewatering and drying.

Concentrating Section  in  Sweet Potato Starch Making Line :
The crashed material is sent to centrifugal sieve through pump to extract starch and separate sweet 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 sweet potato residues. The whole stage adopts countercurrent washing to get the best results and saving water.

De-hydrating section  in  Sweet Potato Starch Making 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 Making Line :
Drying the dewatered sweet potato 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 viscosity.

Features of sweet potato starch making line:

1.Economic type .Calculation is based on the dry starch output.

2.good factory design, processing art consultation, processing machinery manufacturing and after-sale service of spare parts

3.advanced potato deep-process technology and equipment, and the mature production techniques of all kinds of starch.


We also offer design for new starch factory and give consultation and design scheme for innovation of ready old factory, and is responsible for installation, test-run and ensure the follow-up sevice of equipment and technological support.

Our starch production line equipments have been widely used domestically and exported abroad to Vietnam, Indonesia, Thailand, Nigeria, etc. where it is broad accredited by the clients due to its excellent performance and good service for the cvassava starch processing industry and ethanol industry.
