Abstract

A method of producing additional distillers com oil and a high protein product from an ethanol production facility includes obtaining a supply of whole stillage from the ethanol production facility after ethanol has been extracted therefrom; and introducing at least one diluent into the whole stillage, wherein the diluent has a lower solid percentage than the whole stillage, and the mixture of the whole stillage and at least one diluent produces a distillers com oil containing diluted stillage product.

Abstract

The invention is directed to a method of producing a biomass-derived product, comprising filtering through at least one paddle screen a high solids liquefaction slurry that comprises starch and fiber, thereby separating the starch into a starch rich stream and the fiber into a fiber rich stream; and fermenting the starch rich stream to produce a biomass-derived product.

Abstract

Processes and systems for recovering oil from a fermentation product are provided that optimize oil recovery during fermentation. The processes and systems described herein introduce a gas into the fermentation product in order to cause the oil within the fermentation product to separate therefrom, thereby facilitating its subsequent recovery. The processes and systems described herein can maximize the amount of oil that can be recovered during fermentation.

Abstract

A process and system for producing ethanol from a biomass feedstock is provided that improves ethanol production by using a biomass feedstock containing high amounts of solids and starch. The process can involve subjecting the biomass feedstock to a primary fermentation to produce a whole stillage and subjecting this whole stillage to a secondary fermentation. The processes and systems described herein can maximize the amount of ethanol produced in ethanol production facilities.

Abstract

A process of producing ethanol from whole stillage, includes obtaining a supply of whole stillage from an ethanol production facility after ethanol has been extracted therefrom; pre-treating the whole stillage to convert hemicellulose portions of the whole stillage into sugars; adding enzymes to the whole stillage to convert cellulose portions of the whole stillage to sugars; fermenting the whole stillage to create a beer mixture; and distilling the beer mixture to separate ethanol therefrom. The pre-treating step may include adding acid to the whole stillage to decrease its pH level; heating and pressurizing the whole stillage; holding the whole stillage under pressure and heat for a dwell time; removing pressure from the whole stillage to cause flashing; and cooling the whole stillage before the enzymes are added.
