ABSTRACT:
In apparatus for filling cans with beverage the can is coupled to the filler valve and purged of atmospheric air with a mostly inert gas and air mixture derived from the space of the liquid in a storage tank. When the exhaust valve is closed, another valve opens to permit pure inert gas stored in a reservoir to flow into the can and pressurize it to slightly above atmospheric pressure but below the pressure in the storage tank. A pre-pressurization valve is then opened to let some of the inert gas and air mixture in the storage tank flow to the can which is occupied by the substantially pure inert gas so practically none of the downflowing gas and air mixture from the storage tank enters the can although it fills the chamber to which the can is connected and thereby pressurizes the can. When the can pressure and storage tank pressure become equal, a liquid control valve opens to drain liquid from the tank into the can. Liquid flow is shut off in a conventional manner when the liquid level in the can reaches the lower tip of the pre-pressurizing gas return tube. As the liquid beverage flows into the can it displaces the most pure inert gas into the space above the liquid in the storage tank so as to increase the concentration of the inert gas in the storage tank.
