The dry sieve machine is mainly to remove the adhering dirt, sand or other impurities from the sweet potato surface prior to washing. 

After cutting, the sweet potatoes are disintegrated with addition of water into pulp by a rasper machine, which releases the starch granules from the fibrous matrix. The sweet potatoes raw materials become starch slurry which can be considered as a mixture of pulp (cell walls) and starch. The high speed rotating blade in the rasper machine guarantees the grinding efficiency of sweet potato cells that can fully release the starch.
