Abstract
Apparatus providing for the growth of cells in a nutrient bath under controlled conditions includes a pressure vessel with a surrounding dimpled jacket. The pressure vessel is adjustably mounted on three vertical mounting columns, from which it is thermally isolated. Temperature control for the pressure vessel is achieved by a closed heat transfer system which includes a pair of heat exchanger sections in series, one for heating and one for cooling the heat transfer fluid. A removable head or lid for the pressure vessel is lifted by three cables running through a common pulley mounted above the pressure vessel. Impeller blades for agitating the contents of the fermenting apparatus have a drive shaft that extends through the head and is connected to a gear box by a removable driving link. The gear box, and an associated drive motor, are affixed to a common mounting bracket that is pivotable to permit maximum displacement of the head.
