To cassava, the material is sent to cage washer through scrape board to get the result of decontamination, cleaning and peel. Then through a paddle-washing slot, material is sent to crash section.
We adopt the rasper to crash materials. Compared with traditional crasher, it has the large capacity, high starch dissociation degree features, which are essential to get high starch recovery.
The crashed material is sent to centrifugal sieve through pump to extract starch and separate potato residues. Centrifugal sieve group are 4 or 5 stages, the front stages is to extract starch and the last stage is to dewater the potato residue. The whole stage adopts countercurrent washing to get the best results and saving water.
