Abstract
Abstract A method and apparatus for simultaneously carbonating and cooling a liquid beverage. The apparatus includes an upright enclosed vessel with an upright coaxial carbonating column within the same space therefrom to define an upright channel. A source of liquid to be carbonated and liquid carbon dioxide are directed into the lower end of the carbonating column and the product overflows the carbonating column into the annular channel wherein it passes downwardly and out of the vessel. A bypass line of ambient liquid is sprayed onto the top of the carbonating column to dissolve floating ice crystals. Also, a screen is placed between the carbonating column and annular channel to prevent passage of such ice crystals.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
In a system for carbonating and cooling a liquid, a. an upright enclosed vessel, b. an upright carbonating column including a heat conductive wall portion, said column being centrally disposed in and supported by said vessel, said column and vessel defining an upright channel therebetween, c. the upper portion of the carbonating column including an opening in communication with said channel, d. means defining a source of liquid to be carbonated, e. a source line connected between the carbonating column at a location proximal to the lowermost portion of the carbonating column and the means defining a liquid source, f. means defining a source of liquid carbon dioxide, g. means for injecting liquid carbon dioxide from its means defining a source into liquid to be carbonated, said carbon dioxide being introduced into said carbonating column at a location proximal to the lowermost portion of said carbonating column, and h. an outlet line connected to a lower portion of the channel for removing cooled carbonated liquid therefrom, wherein said carbonating column is of sufficient height to provide sufficient residence time to accomplish stabilizing of the carbon dioxide bubbles in the liquid.
Claim 2
Dependent Claim
190 words
In a system for carbonating and cooling a liquid, a. an upright enclosed vessel, b. an upright carbonating column including a heat conductive wall portion, said column being centrally disposed in and supported by said vessel, said column and vessel defining an upright channel therebetween, c. the upper portion of the carbonating column including an opening in communication with said channel, d. means defining a source of liquid to be carbonated, e. a source line connected between the carbonating column at a location proximal to the lowermost portion of the carbonating column and the means defining a liquid source, f. means defining a source of liquid carbon dioxide, g. means for injecting liquid carbon dioxide from its means defining a source into liquid to be carbonated, said carbon dioxide being introduced into said carbonating column at a location proximal to the lowermost portion of said carbonating column, and h. an outlet line connected to a lower portion of the channel for removing cooled carbonated liquid therefrom, wherein said carbonating column is of sufficient height to provide sufficient residence time to accomplish stabilizing of the carbon dioxide bubbles in the liquid.
Claim 3
Dependent Claim
27 words
The system of claim 1 in which said vessel and carbonating column are coaxial and of generally cylindrical shape so that said channel is of annular configuration.
Claim 4
Dependent Claim
19 words
The system of claim 1 in which said liquid carbon dioxide injection means is disposed in said source line.
Claim 5
Dependent Claim
57 words
The system of claim 1 together with a bypass line connected at one end of said source line for said liquid to be carbonated and terminating at its other end at a position sufficiently proximal to the interior of the upper portion of the carbonating column to spray said liquid to be carbonated into said carbonating column.
Claim 6
Dependent Claim
23 words
The system of claim 4 in which said other end of the bypass line includes means for spraying liquid into said carbonating column.
Claim 7
Dependent Claim
19 words
The system of claim 1 together with screen means disposed in the opening between said carbonating column and channel.
Claim 8
Dependent Claim
35 words
The system of claim 1 together with means defining a source of gaseous carbon dioxide under pressure, and means for injecting carbon dioxide from said last named means defining a source into said source line.
