NOVELTY - A cereal (corn or wheat) refining process comprises steeping cereal kernels (100) in aqueous liquid to produce softened cereal; milling softened cereal (200) to produce milled cereal comprising germ, protein, starch, and fiber; separating at least some of at least one material consisting of germ, starch, and protein to produce at least one of germ, starch, and first protein portion (220), and also producing first fiber portion comprising fiber and starch, and light steep water comprising protein; and burning (600) at least some of fiber to produce flue gas (620) and first quantity of energy;    USE - Method for cereal (corn or wheat) refining process (claimed).    ADVANTAGE - The process can be performed on batch, semi-batch, and/or continuous basis; provides greater yield of dextrose or ethanol, and achieves similar yield of ethanol but provides better yield of germ and protein than conventional cereal wet milling process compared to conventional wet milling processes; and allows recovery of ash-based products which may be variously used as fertilizer additives, land application materials, or cement additives. The extraction of energy from fiber burning or biogas burning reduces external energy inputs, thus yielding more carbon-neutral milling process than previously known.    DETAILED DESCRIPTION - The cereal refining process comprises:    (A) steeping cereal kernels (100) in aqueous liquid to produce softened cereal;    (B) milling softened cereal (200) to produce milled cereal comprising germ, protein, starch, and fiber;    (C) separating at least some of at least one material consisting of germ, starch, and protein from milled cereal to produce at least one of germ, starch, and first protein portion, and also producing first fiber portion (220) comprising fiber and starch, and light steep water comprising protein; burning (600) at least some of fiber to produce flue gas (620) and first quantity of energy;    (D) powering at least one previous step with first quantity of energy; and    (E) drying at least one separated material consisting of germ, starch, protein, and saccharides with flue gas to produce dried separated material and dryer exhaust.
