A fermentation apparatus for preserving the aroma of a fermentable beverage is provided. The fermentation apparatus comprises a flow passage fluidly connectable to the headspace located above a fermentable beverage in a fermentation container. A carbon dioxide scrubber in the flow passage receives a headspace fluid mixture comprising at least carbon dioxide gas and an aromatic fluid originating from the fermenting beverage. When the headspace fluid mixture contacts the carbon dioxide scrubber, the carbon dioxide scrubber retains a modified fluid in the flow passage. The modified fluid has a lower carbon dioxide gas concentration and a higher aromatic fluid concentration than the headspace fluid mixture. The flow passage directs the modified fluid back to the headspace to at least partially retain the aromatic fluid in the fermentable beverage in the fermentation container. A method for preserving the aroma of a fermentable beverage is also provided.

Provided are methods and systems for remediating toxins present in feedstock that are used in processes to produce ethanol and other products.

A device is provided having a fermentation chamber having one or more inlets to receive a mixed stream to be fermented and an outlet to release fermented product; a distillation vessel surrounding the fermentation chamber having communication with the fermentation chamber outlet to receive fermented product to be distilled and a turbine located within the outlet of the fermentation chamber, the turbine having a rotor rotatable by force of flow of fermented product from the fermentation chamber to the distillation vessel, to generate electricity. A sidewall common to both the fermentation chamber and distillation vessel allows for heat transfer of heat generated from fermentation to the distillation vessel to heat the product to be distilled. A method of fermenting and distilling a product is also provided. The method involves receiving in a fermentation chamber a mixed stream to be fermented; transferring heat energy generated by fermentation to a distillation vessel surrounding the fermentation chamber; allowing pressurized fermented product to flow from the fermentation chamber into the distillation vessel via a turbine and rotating a rotor of the turbine by a force of flow of the fermented product to the distiller to generate electricity.

A system and method for expanding the production capacity of an existing ethanol production facility including: a source of fermented mash (beer); a first beer column configured for receiving beer input from the source and for producing overhead comprising alcohol vapor and water vapor; and a first rectifier receiving an alcohol and water mixture from said first beer column. The system includes a second beer column, first and second condensers receiving overhead from the beer columns and a second rectifier receiving condensed overhead from the second condenser and bottoms from the first rectifier. A processing component receives bottoms from the first and second beer columns and steam condensate. The method includes the steps of retrofitting an existing ethanol production facility with a second beer column, first and second condensers and a second rectifier.
