Cassava been feed into raw material silo by loader. Then cassava will fall on belt conveyor uniformly by means of vibration device below silo. After that cassava will passing through two stages of cleaning devices dry sieve and washing slot. Cleaned cassava will be crushed into slurry by means of two stages smashing, cutting machine and rasper. The slurry will be transported into centrifuge sieve by screw pump to remove fiber. Then remove small practical of fiber by fine fiber sieve. Then the slurry will enter refining and concentration stage. There are disc separator and hydro cyclone station design according to design capacity requirement. Starch slurry concentration will increase to be 20-22 Baume after refining stage. Then it will be pumped into peeler centrifuge for dehydration. Starch cake after dehydration will be blend and below up into drying pipe system by the winnow. The final starch product will be collected in the buffer tank and packing and transported into the warehouse.
