Abstract
A method is provided for treating distiller's grains with solubles (DGS) to produce one or more byproducts. The method includes separating the DGS into a low protein mixture and a high protein mixture. The method includes generating, from the low protein mixture, a biogas by an anaerobic digestion process. The method includes generating, from the high protein mixture, at least one of a vegetable oil from a vegetable oil separation process, a high protein animal feed from a separation process and a microalgae biomass material from a microalgae production process.
Claims11
A method for treating distiller's grains with solubles (DGS) to produce a high protein animal feed, the method comprising:
- treating the DGS with a steeping process that includes using a chemical;
- treating the DGS with a size reduction process;
- then separating the DGS into a low protein mixture and a high protein mixture;
- and
- generating, from the high protein mixture:
- a high protein animal feed from a separation process, wherein a percentage of protein content in the DGS is between about 25% and about 30%.
A method for treating distiller's grains with solubles (DGS) to produce a high protein animal feed, the method comprising:
- treating the DGS with a steeping process that includes using an enzymatic solution;
- treating the DGS with a size reduction process;
- then
- separating the DGS into a low protein mixture and a high protein mixture;
- and
- generating, from the high protein mixture:
- a high protein animal feed from a second separation process, wherein a percentage of protein content in the DGS is between about 25% and about 30%.
