Abstract
This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by applying non-condensable media to create density differences and then using a mechanical device to separate the solids from the liquids based on the density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.
Claims18
A method comprising:
- separating with a separation device a fractionated stillage stream to provide a heavy phase with suspended solids stream and a light emulsion phase stream;
- fermenting with a fermentation vessel at least a portion of the heavy phase with suspended solids stream and an organism to provide a fermentation mixture comprising at least the portion of the heavy phase with suspended solids stream and the organism;
- wherein the fermenting converts a carbon source of the fermentation mixture to generate a feed product;
- and
- drying the feed product to provide a dried feed product, wherein the dried feed product has an amino acid content of lysine of from about 1% to about 9% dry basis.
A method comprising:
- separating with a separation device a fractionated stillage stream to provide a heavy phase with suspended solids stream and a light emulsion phase stream;
- fermenting with a fermentation vessel at least a portion of the heavy phase with suspended solids stream and an organism to provide a fermentation mixture comprising at least the portion of the heavy phase with suspended solids stream and the organism;
- wherein the fermenting converts a carbon source of the fermentation mixture to generate a feed product, and wherein a concentration of the organism in the fermentation mixture is from about 1% to about 30% by volume.
A method for separating components in a fractionated stillage stream, the method comprising:
- separating with a first separation device the fractionated stillage stream to provide a heavy phase with suspended solids stream and a light emulsion phase stream;
- fermenting with a fermentation vessel at least a portion of the heavy phase with suspended solids stream and an organism to provide a fermentation mixture comprising at least the portion of the heavy phase with suspended solids stream and the organism;
- wherein the fermenting converts a carbon source of the fermentation mixture to a biomass;
- and
- separating with a second separation device the fermentation mixture to provide a separated liquids stream and a separated solids stream that includes at least a portion of the biomass,
- wherein the separated solids stream forms at least a part of a feed product.
