SOLVENT EXTRACTION OF OIL FROM DISTILLERS DRIED GRAINS AND METHODS OF USING EXTRACTION PRODUCTS

摘要

A process for extraction of crude oil from distillers dried grain solubles and/or distillers dried grains and producing corn distillers meal that may be used as a livestock supplement is disclosed. For example, the corn distillers meal may be used as a crude protein supplement for use in a livestock feed diet or a poultry feed diet. The solvent extracted crude oil may be suitable for oleochemical processing for personal care and home care products, biodiesel production, and/or renewable diesel production from hydro-treating the extracted oil to make green diesel fuel.

1. A facility for solvent extraction of distillers dried grains with solubles, distillers dried grains, or both, comprising:
a solvent extraction facility configured to extract crude plant oil from the distillers dried grains with solubles, the distillers dried grains, or both, thereby producing distillers meal, wherein the solvent extraction facility is configured to extract crude plant oil from distillers dried grains with solubles, the distillers dried grains, or both, using an extraction process using a non-polar solvent having a boiling point in the range of about 36° C. to about 99° C., thereby producing distillers meal comprising a crude protein content ranging from about 28% to about 35% by weight on, a crude fat content ranging from about 0.25% to about 6% by weight, and a content of phosphorous and phosphorous containing compounds ranging from about 1 ppm to about 50 ppm.
