Abstract
The present disclosure relates methods and systems for refining grain oil compositions using water, and related compositions produced therefrom. The present disclosure also relates to methods of using said compositions. The present disclosure also relates to methods of using grain oil derived from a fermentation product in an anti-foam composition.
Claims26
A method of recovering a byproduct of a grain oil composition feedstock from distillers corn oil, the method comprising:
- recovering whole stillage from distillation of a grain feedstock;
- separating the whole stillage into wet cake and thin stillage;
- processing the thin stillage in a separator to recover a grain oil composition feedstock;
- cooling the grain oil composition feedstock to form a temperature adjusted grain oil composition feedstock including a grain oil product and a byproduct of the grain oil composition feedstock;
- recovering the byproduct of the grain oil composition feedstock;
- and
- wherein the byproduct of the grain oil composition feedstock is any fraction or phase separated from the temperature adjusted grain oil composition feedstock other than the grain oil product.
A method of recovering a grain oil product low in impurities from distillers corn oil, the method comprising:
- recovering whole stillage from distillation of a grain feedstock;
- separating the whole stillage into wet cake and thin stillage;
- processing the thin stillage in a separator to recover a grain oil composition feedstock;
- cooling the grain oil composition feedstock to form a temperature adjusted grain oil composition feedstock including a grain oil product and a byproduct of the grain oil composition feedstock, wherein the byproduct of the grain oil composition feedstock is any fraction or phase separated from the temperature adjusted grain oil composition feedstock other than the grain oil product;
- and
- recovering the grain oil product and wherein a level of impurities in the grain oil product is less than a level of impurities in the grain oil composition feedstock.
