In this section, the mainly used potato starch processing machine includes dry sieve and rotary washer. Dry sieve is mainly used to remove the sand, impurities and dirty on the potato appearance. Normally when dry sieve will produce many impurities when it works, so the professional engineer of Doing Company suggest that the machine should be installed outside of workshop.

The main potato starch processing machine used in this section are rasper, centrifugal sieve, fine fiber sieve, desander, hydro cylcone station etc. After washing, the potatoes are transported into the storage hopper then to a rasper to be crushed into potato pulp. The potato crushing yield of a high efficiency rasper can be up to 95%. DOING rasper is designed with our professional engineer with 30 years of experience and introduce international technology, which can reach a 95% crushing rate. Then, the potato slurry is pumped to the horizontal centrifugal sieve to separate the starch and fiber.

The used potato starch processing machine includes vacuum filter, flash dryer and packaging machine. Potato starch is a kind of macromolecule which has bigger size than cassava starch, so a vacuum filter is normally used for potato starch dewatering. This potato starch processing machine can effectively dewater the wet starch milk to a moisture content around 38%~40%
