ABSTRACT:
Fermentation equipment is provided with multiple rotating conical surfaces which create a flow of the liquid phase along the conical surfaces and produce a forced flow of the gaseous phase across the liquid phase, thus resulting in much improved mass transfer between the phases and preventing the formation of foam. The equipment is provided within a standard sterilizable fermentation vessel at the bottom of which is located propeller means for circulation of the liquid phase, cylindrical heat exchanger means for heating or cooling the liquid phase and a gas sparging system for introduction of the gaseous phase.
