ABSTRACT:
A fermentation apparatus of the loop flow type includes tubular member forming a continuous or substantially continuous loop flow path defined by the interior surface of the tubular member. A heat exchanger surrounds a portion of the tubular member and is in heat transfer relation thereto and inside the tubular member at the point where the heat exchange means surrounds the tubular member mixing vanes or fins are secured to the tubular member to effect mixing of medium flowing through the tubular member. A spray nozzle is provided just upstream of the mixing vanes and is operable for discharge of medium into the flow path adjacent the heat exchange means. A pump is connected to the nozzle and pressurizes medium taken from the flow path and discharges same through the nozzle. Injectors open into the flow path adjacent the heat exchange means and are operable for introducing an oxygen-containing gas into the medium contained in the flow path. A phase separator has an inlet and outlet communicating with the flow path and is operable for receiving a portion of the medium for separating same into a gas phase and liquid phase and returning a portion of the liquid phase to the flow path.
