Potato Starch Processing Plant
The main characteristic of this process: the whole potato starch processing 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 whole process can be divided into the following units:
1 Potato Washing/De-stone Unit
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 Broken Unit
Potatoes feed rasping machine through screw conveyer. In order to production line not to stop when changing the saw blade, it should install the second rasping machine.
3 Starch Extraction/Fiber Separation Unit
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 Enrichment Unit
Down from extraction process in the first level of cone sieve starch slurry pump into rotary self-cleaning filter. Then starch slurry is concentrated.
5 Desand Unit
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.
6 Refined Unit
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%.
7 Fine Fibre Sieve/Dehydration Unit
Starch slurry in starch jar after refined, and then removes moisture through vacuum filter. The wet starch water content after dehydration is 38—40%.
8 Starch Dry Unit
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 processing plant completed.
