The following is the detail introduction of potato starch machinery:

(1) Dry sieve: The potato is carried besides the storage pool after weighing. The firstly used potato starch machinery is dry sieve which is used for removing the stones, and and other debris. Then the pre-cleaned potato falls on the screw conveyer and enters into the storage pool, and the rubbish will be carried away by truck.

(2) Drum-type washer: The remaining sand and dirt will be cleaned out in rotary washing machine by rolling and friction. This potato starch machinery is low water and power consumption.

(3) Rasper: After the cleaning and washing process, the potato is crushed in rasper which is a high efficient potato starch machinery. The breaking rate of potato is up to 95%.

(4) Centrifuge sieve: The centrifuge sieve is a potato starch machinery used for separating potato starch slurry and fibers.

(5) Desander machinery: the sand and residue will go out from the cyclone of this potato starch machinery because of the specific gravity. And then we can get the starch milk with less impurities.

(6)Hydrocyclone station: The starch milk from desander goes into the 18 stages of refining hydrocyclone separator, and fresh water comes into the cyclone from the end of this potato starch machinery. Firstly, starch milk is pumped into 3 stages of concentration unit to remove the water, then the condensed starch milk enter the next 13 stages of washing unit, and the overflow enters into another 2 stages of recycle unit to recycle starch. Most of the effluent with fiber is discharged out of the process, and a little part goes back to the process water system. Finally, the condensed starch slurry is pumped into the starch slurry storage tank.

(7) Vacuum dewatering machinery: The starch slurry is pumped into inlet tank of vacuum filter. Then the rotary drum of this potato starch machinery 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 drying and packing machinery: After dewatering process, the air dryer will dry the starch to the required moisture of the commercial starch. And the last potato starch machinery is semi-automatic packing machinery which is used to pack the collected starch for storage.
