Potato starch processing plant description

Starch is very normal in our daily life, it is one important raw material of many delicious food. Potao, sweet potato and cassava can be made for starch.Then how do we make the starch from potato? Following are the main sections during potato starch processing plant:

crushing machine

Crushing machine

Washing & crushing section

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 crush potatoes. Compared with traditional crasher, it has the large capacity, high efficiency, 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 and refining section

This section is the most important section during potato starch processing plant. It directly influent the starch quality. 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 discharge 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 screw conveyer.

Drying section

Drying the dewatered potato starch in the air crash dryer to get dry product fine starch. Dried starch reaches sieving system. High efficiency cooling starch sifter is used to cool starch and get the best final product potato starch.

Above are the main sections of potato starch processing plant. Any questions about the potato starch processing plant, please feel free to contact us, we will offer you the professional knowledge of potato starch processing and supply you available potato starch project proposal.
