  • Method for separating mill starch to obtain a protein-rich product and a starch-rich product
    Patent number: 4244748
    Abstract: A system for separating the mill starch fraction in a corn wet milling operation into a protein enriched stream and a starch enriched stream to obtain therefrom a protein-rich product and a starch-rich product. The system utilizes only hydrocyclones arranged in a plurality of separation stages that are divided into two separation zones. The mill starch is fed sequentially through the two separation zones under controlled conditions so as to obtain a protein-rich product from one separation zone and a starch-rich product from the other separation zone.
    Type: Grant
    Filed: January 22, 1979
    Date of Patent: January 13, 1981
