| Potato starch production plant |
The main characteristic of this process: the whole potato starch production plant adopts closed way and spiral flow device，low consumption, high efficiency and good product quality. In the process of starch recovery and purification, no longer use the centrifuge but spiral flow station, so as to avoid the extensive use of the moving parts.
The potato starch production plant process can be divided into the following units:

| Potato starch production plant process |
1. Potato Washing/De-stone Unit in potato starch production plant :
New harvest potatoes from the ground should first dry and sieve to remove the impurities as much as possible, and then stored in daily designated area.
2. Crushing Unit in potato starch production plant :
Potatoes feed rasping machine through screw conveyor. In order to production line not to stop when changing the saw blade, it should install the second rasping machine.
The potato paste after breaking mixed with water then pump into the first level screen, the wet fiber comes down from the first screen is pumped into the second, third and the fourth extraction screen, be sent to the fiber dryer dehydration. Wet residue dry matter content after dehydration is 10-12%
4. Desand Unit in potato starch production plant :
Starch milk after concentration is sent to a mixing tank, and then starch can use two levels of de-sander expel sand, the sand collected uses butterfly valve to eject.
At this time the starches with 12-14 level cyclone stand to clean, refined. Refined unit automatic work and is equipped with the necessary instruments. Starch slurry concentration after the refined is 35-40%.
6. Dehydration Unit in potato starch production plant :
Starch slurry in starch jar after refined, and then removes moisture through vacuum filter. The wet starch water content after dehydration is 38—40%.
The product after drying uses high efficiency cyclone to collect, finished products of drying machine use pneumatic conveyor or screw conveyor to cool, cooling dry starch will use two stage cyclone separator collection and screw conveyor sends to the sieving machine, after screening to package warehousing.The whole potato starch production plant completed.
