Abstract: Processes for grinding corn, ground corn products, and processes for making ethanol from the ground corn products. In some examples, a process for making ethanol can include introducing a plurality of corn pieces into a mill. The process can also include milling the corn pieces in the mill to produce a ground corn product. Greater than 25 wt % of the ground corn product can have a particle size of greater than 105 μm, as measured according to AOAC 965.22-1966. Greater than 80 wt % of the ground corn product can have a particle size of 425 μm or less, as measured according to AOAC 965.22-1966. The process can also include processing the ground corn product to produce a fermentation mash that can include ethanol and separating at least a portion of the ethanol from the fermentation mash to produce a stillage.

Abstract: Processes and systems for recovering products from a fermentation mash. In some examples, a process for recovering products from a fermentation mash can include processing a ground corn product to produce a fermentation mash that can include ethanol. At least a portion of the ethanol can be separated from the fermentation mash to produce a whole stillage. The whole stillage can be separated to produce a fiber rich product and a filtrate. The fiber rich product can be hydrolyzed to produce a saccharification mash. The saccharification mash can be processed to produce additional ethanol and a stillage protein product.

Abstract: Processes and systems for recovering products from a corn fermentation mash. In one example, a process for recovering products from a corn fermentation mash can include separating ethanol from a fermentation mash to produce a whole stillage. The fermentation mash can be derived from a ground corn product milled from a plurality of corn pieces. The plurality of corn pieces can include whole corn kernels, fragmented corn kernels, size-reduced corn kernels, milled corn kernels, or a mixture thereof. Greater than 25 wt % of the ground corn product can have a particle size of greater than 105 μm and greater than 80 wt % of the ground corn product can have a particle size of 425 μm or less, as measured according to AOAC 965.22-1966. The process can also include separating the whole stillage to produce a fiber rich portion and a filtrate.
