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.
Claims20
A method for separating components in a fractionated thin stillage stream, the method comprising:
- separating liquids from solids in the fractionated thin stillage stream having about 4% to about 14% total solids, to provide a heavy phase with suspended solids stream and a light emulsion phase stream;
- adding an organism to the heavy phase with suspended solids stream to provide a fermentation mixture;
- aerobically fermenting the fermentation mixture;
- converting a carbon source in the fermentation mixture to a biomass;
- separating the fermentation mixture through a device to create a separated liquids stream and a separated solids stream;
- and
- using the separated solids stream which includes the biomass, to form part of a feed product.

A method comprising:
- receiving a fractionated thin stillage stream having 3% to about 12% by weight of total solids;
- separating the fractionated thin stillage stream into a light emulsion phase and a heavy phase with suspended solids;
- adding an organism to the heavy phase with suspended solids, wherein the organism comprises at least one of Candida utilis, Saccharomyces cerevisiae, Pichia stiptis, Pichia pastoris, Escherichia coli, Kluyveromyces marxianus, Corynobacterium lilim, and Corynobacterium glutamicum;
- aerobically fermenting the organism with the heavy phase with suspended solids;
- converting a carbon source in the heavy phase with suspended solids to generate a feed product;
- and
- drying the feed product.
