In fiber sieves, protein sieves also have different machines that can be chosen according to the buyer’s requirements. There are fine fiber sieves, centrifuge sieves, and hydrocyclone stations that can choose to get different separating rates. After processing moisture content will be around 40%, then dewatering by vacuum filter and drying by flash dryer, and sieving.
