Abstract: Systems and methods for fractionating whole stillage from an ethanol production facility are provided. Whole stillage undergoes a separation of its liquid portion (thin stillage) from the solid portion (fiber cake). In some embodiments, the solids and liquids in whole stillage may be separated utilizing a screening centrifuge. The fiber cake may be dried to generate a high fiber animal feed. The thin stillage may be provided to a three-phase separator for separation into an oil emulsion, an aqueous clarified stillage, and a protein paste. The protein paste may be dried to generate a high protein animal feed with greater than about 45% protein content. The clarified thin stillage is condensed to yield a syrup with greater than around 60% solids. The oil emulsion is subjected to a pH adjustment to liberate the oil from the emulsion, which is then separated.

Abstract: Systems and methods for improving stillage are disclosed. Stillage may include either whole stillage or thin stillage. The system includes taking the stillage and placing it within a bioreactor with an inoculation of fungi. The fungi may include any of Aspergillus niger, Phanerochaete chrysosporium and Yarrowia lipolytica. The fungi and stillage broth is then subjected to fermentation which removes solubles and particulates from the stillage. The fungi generate a biomass material that may be collected and dried for use as a nutritional supplement or other purpose. The remaining liquid is a clarified, treated stillage suitable for a variety of downstream applications, including being used as a backset in an ethanol production facility.
