Process of sweet potato starch equipment processing line

(1) Raw material receiving and screw conveying: The sweet potato is carried and transported on the conveyer.

(2) Water cleaning and destoning : The water will wash the sweet potato and destoning during the process of conveying.

(3) Crushing: The crushing unit is the most important step for extracting sweet potato starch. Highly-efficient crushing machine will release the starch in sweet potato at most.

(4) Centrifugal extracting:The starch slurry and residue  will be separated from the starch milk.

(5). Desanding: Removing the sand in the starch slurry.

(6) Concentration and refining:Working through the hydroclone, there are 2 steps, including concentration and refining so that we can get purier starch slurry.

(7) Vacuum dewatering: The starch slurry is pumped into inlet tank of vacuum dewatering machine. Then the vacuum rotary drum will adsorb the starch on the drum surface and the filtrate is transferred out of the system by filtrate pump. The filter cake on the drum will be peeled off by peeler and then transferred to the air dryer by screw conveyor.

(8) Air-stream drying: After dewatering process, the air dryer will dry the starch to the required moisture of the commercial starch.
