摘要： 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.

摘要： Improved processes and systems for recovering products from a corn fermentation mash. In some examples, a process recovers an oil product, a protein meal product, and a fiber product from a slurry. A process includes the following steps: introducing the slurry into a device with a flexible screen and mechanical agitation to produce a filtrate and a fibrous solid stream; and introducing the filtrate into a three-phase centrifuge to produce an oil stream, a high protein solids stream, and a water with solubles stream. The flexible screen includes a washing nozzle. The slurry is whole stillage from an ethanol process. The three-phase centrifuge is a three-phase decanter. The filtrate is heated before introducing into the three-phase centrifuge. The filtrate is optionally evaporated before introducing into the three-phase centrifuge.

摘要： 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.
