Model Rasper -Rasing

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.
