  • Patent number: 5192513
    Abstract: A process and apparatus for rapidly carbonating water for use in applications such as beverage mixes by producing carbon dioxide gas by chemical reaction within a first pressure vessel, transferring the carbon dioxide to a second pressure vessel where it is injected under pressure beneath the water in the second pressure vessel to carbonate the water therein while maintaining sufficient pressure to prevent dissolved carbon dioxide from coming out of solution in the water and for dispensing the carbonated water upon demand. Restrictive venting of the second pressure vessel may be used if needed, to aid in the transfer of carbon dioxide from the first to the second pressure vessel.
