1. A process for a fermentation facility, the process comprising:
(i) providing a grain feedstock;
(ii) dividing the grain feedstock into at least a first grain feedstock portion and a second grain feedstock portion;
(iii) providing the first grain feedstock portion to a first process flow comprising:
(a) saccharifying the first grain feedstock portion to produce at least one monosaccharide sugar; and
(b) fermenting at least a portion of the at least one monosaccharide sugar to produce one or more biochemicals; and
(iv) providing the second grain feedstock portion to a second process flow different from the first process flow, the second process flow comprising:
(a) saccharifying the second grain feedstock portion to produce a sugar stream comprising at least one monosaccharide sugar; and
(b) separating grain fiber from the second process flow and introducing at least a portion of separated grain fiber into the first process flow so that separated grain fiber is provided to and/or after the fermenting at least a portion of the at least one monosaccharide sugar to produce one or more biochemicals.
