Simultaneous Food And Fuel Corn Refining

摘要

Food grade products are given priority with a sustainable integrated corn based bio grind refining process. Premium fractions are fractionated for human foods and premium fermentable products. The balance food feedstocks are refined for animal feed with no loss of nutritional value. By-products of refining are used to produce ethanol and other energy products. There is no process waste. The integrated processes can be adapted to new continuous refineries or to optimize or retrofit one or more individual process steps.

主权项

1. A sustainable integrated bio grind refining process for a feedstock of corn and corn stover, the process operating batch or continuous to produce fuel ethanol, the process comprising:
(a) feeding 15 to 30 percent of the feedstock to a wet grind stream; (b) feeding 15 to 18 percent of the feedstock to a dry grind stream; (c) feeding 15 to 30 percent of the feedstock to a ligno cellulose stream; and (d) processing the feedstock to form germ, steep liquor, high protein soft starch, pre-liquefaction corn germ, post-distillation corn oil, and by-products of standard DPGS, low oil DPGS, high protein DPGS, and batch feed lignin.
