Abstract
A fermentation vessel comprises an outer shell, and an annular draft tube located within the shell and spaced therefrom to promote continuous circulation of fluids through said draft tube within said shell. The draft tube has an internal cavity located within its walls. The cavity is connected to a fluid supply conduit that extends externally of the shell. A plurality of discrete nozzles are disposed about the circumference of the tube and communicate with the cavity to permit egress of fluids from the cavity to the interior of the shell to promote circulation.
