High efficiency sand removal Rotary Peeler is specially designed for underground tuber raw materials with high sediment content, realizing deep sand removal, mud removal and impurity removal while peeling, effectively avoiding sediment wear to subsequent crushing and separation equipment, extending production line service life. The equipment adopts multi-stage countercurrent scouring technology, which can completely remove sediment impurities on the surface and recesses of raw materials, no additional sand removal equipment is needed, simplifying production process and reducing equipment investment. The raw material cleanliness is greatly improved, which can significantly increase starch whiteness and purity, improve product quality and enhance market competitiveness.
