Desanding, protein isolation and starch refining(7)

The crude starch separated from the pressure curved sieve (fiber) is removed by a desander and then enters a disc separator to separate out protein and light gluten (1 - 2% dry matter). The protein enters the protein concentration and drying section. The starch milk separated by the disc separator has a concentration of 15 - 17 °Be, and is pumped into a 13-stage washing and concentration cyclone. The refined starch milk washed and refined by the cyclone has a water content of about 62%, and is stored in a refined starch tank for dehydration.
