A corn oil extraction process is disclosed. The process includes the recovery of corn oil and other co-products, including but not limited to steam, electric power and chemicals, from an ethanol production process and in particular, a process that involves dry corn milling methods. The process involves extraction of oil from milled corn and residues from the fermentation step, including thick stillage, distillers wet grain, distillers dry grain and distillers dry grains with solubles, by the application of an alkyl acetate, phase separation and recovery of the separated matter. A process of drying wet co-product using ethanol and carbon dioxide from the production facility is also disclosed.
L'invention concerne un processus d'extraction d'huile de maïs. Ce processus comprend la récupération d'huile de maïs et d'autres coproduits notamment, mais non exclusivement, de vapeur, d'énergie électrique, et de produits chimiques, dans un processus de production d'éthanol, et en particulier dans un processus utilisant des méthodes de mouture à sec de maïs. Ce processus consiste à extraire de l'huile du maïs moulu et des résidus de l'étape de fermentation, notamment la vinasse entière, la drêche humide de distillerie, la drêche sèche de distillerie, et la drêche sèche avec solubles, par application d'un acétate d'alkyle, séparation des phases, et récupération des matière séparées. Un processus de séchage du coproduit humide par l'utilisation d'éthanol et de dioxyde de carbone issus de l'installation de production est également décrit.
