Abstract
Deoxygenating apparatus and method for use with a system for producing deoxygenated beverages comprises a deoxygenating column with stacked units each comprising a distributor plate and a subjacent shallow tray, both of which are perforated for downward dripping of water. Carbon dioxide gas flows upwardly, counter to the water, in a serpentine path over the plates and trays and through the dripping water for replacing the air in the water by the carbon dioxide gas. The water flow rate and extent of perforation of the plates and trays is such that films of water cover the respective plates and trays to permit some of the carbon dioxide gas to bubble through the plates and trays and thereby enhance the absorbtion of the gas into the water.
