Abstract (en)
[origin: WO2020160644A1] A fermentation apparatus and method for preserving the aroma of a fermentable beverage is provided. The fermentation apparatus comprises a flow passage fluidly connected to the headspace located above a fermentable beverage in a fermentation container. A rubbery membrane in the flow passage receives a gaseous headspace fluid comprising carbon dioxide gas and a first concentration of an aromatic fluid. The rubbery membrane strips a portion of the aromatic fluid from the gaseous headspace mixture thereby reducing a concentration of the aromatic fluid in the headspace mixture in the upstream portion of the flow passage. A first portion of the gaseous headspace mixture from the fermentation apparatus is discharged, the first portion having a second concentration of aromatic fluid less than the first concentration. Carbon dioxide is diffused from a second portion of the gaseous headspace mixture through the rubbery membrane, the diffused carbon dioxide gas entraining the aromatic fluid at the permeate side of the rubbery membrane. The flow passage directs the permeated modified fluid back to the headspace to at least partially retain the aromatic fluid in the fermentable beverage in the fermentation container.
