Abstract
A pump-over fermentation tank has a valve between the pump-over chamber and fermentation chamber providing multi-directional diffusion of the pump-over liquid into the fermentation or extraction chamber. The valve is opened slowly for irrigation of the fermentation cap and is opened rapidly to achieve mixing of the contents in the fermentation chamber. The valve is self-centering in the near-closed position, and in a particular embodiment has diffusers on the perimeter of the valve to direct the pump-over liquid to different regions of the surface of the contents in the fermentation chamber.
