Abstract
An apparatus for chilling and carbonating a liquid comprising a source of carbon dioxide disposed in a container the carbon dioxide in a container being capable of existing in both a liquid and gaseous state, the gaseous state above the liquid state. The container has an outlet opening in the top thereof and a dip tube is disposed in a container for selectively accommodating the flow of liquid carbon dioxide from the bottom of the container through the outlet opening. A tank is provided for holding a supply of liquid to be carbonated and a conduit connects the outlet opening of a container to the inlet opening of the tank. An orifice is provided in the conduit for creating a pressure drop to assure that all carbon dioxide flowing through the conduit is in liquid form and is injected in liquid form into the tank to thereby vaporize the injected liquid carbon dioxide and agitate, carbonate and chill the liquid in the tank. Suitable vents are provided in the tank for releasing carbon dioxide gas caused by the vaporization of liquid carbon dioxide wihch exceeds a predetermined pressure.
