Abstract
An improved fermentation device and method uses a combination of substantially pure Oxygen as the Oxygenation gas and a separate air (or other Oxygen reducing gas) purge through the headspace of a fermentation device. The air injection and air purge vent line are configured to maintain a backpressure within the headspace. The air purge permits improved oxygen utilization and increases safety through dilution and removal of ammonia gas emitted during fermentation.
