Abstract
Abstract An improvement in a process for introducing carbon dioxide into a liquid flowing through a main line, the improvement residing in withdrawing a portion of said liquid through a by-pass line, introducing carbon dioxide into said liquid while in said by-pass line and returning the carbon dioxide enriched liquid to said main line while adjusting the amount of carbon dioxide introduced into said by-pass line to provide a desired carbon dioxide concentration in said liquid in said main line and a device therefore. The process and device disclosed are especially useful for introducing a gas into a beverage, for example, beer, mineral water, barley water, fruit juices, milk and generally alcoholic and nonalcoholic carbon dioxide containing beverages.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
A device for introducing carbon dioxide into a liquid which comprises a main line through which a liquid can pass, a bypass line branching from said main line at a first point and returning to said main line at a second point, means for introducing carbon dioxide into said liquid maintained in said by-pass line, said means comprising a jet producing system which in turn comprises a driving jet nozzle connected to said bypass line, said bypass line having a low pressure chamber in fluid communication with a source of carbon dioxide, the cross sectional areas in said jet producing system being in the ratios: f 1 :f 2 :f M =1:(0.2 to 0.45):(1.3 to 2.6), where f 1 is the cross sectional area of the outlet of said driving jet nozzle, f 2 refers to the induction channel inlet in the plane of said driving jet nozzle outlet and f M is the bore area of a mixing tube which mixing tube is in fluid communication with the outlet of said driving jet nozzle said mixing tube being cylindrical and having a length equal to 24.5 to 30 times the internal diameter d M of said mixing tube.
Claim 2
Independent Claim

A device for introducing carbon dioxide into a liquid which comprises a main line through which a liquid can pass, a bypass line branching from said main line at a first point and returning to said main line at a second point, means for introducing carbon dioxide into said liquid maintained in said by-pass line, said means comprising a jet producing system which in turn comprises a driving jet nozzle connected to said bypass line, said bypass line having a low pressure chamber in fluid communication with a source of carbon dioxide, the cross sectional areas in said jet producing system being in the ratios: f 1 :f 2 :f M =1:(0.2 to 0.45):(1.3 to 2.6), where f 1 is the cross sectional area of the outlet of said driving jet nozzle, f 2 refers to the induction channel inlet in the plane of said driving jet nozzle outlet and f M is the bore area of a mixing tube which mixing tube is in fluid communication with the outlet of said driving jet nozzle said mixing tube being cylindrical and having a length equal to 24.5 to 30 times the internal diameter d M of said mixing tube.
Claim 3
Dependent Claim
50 words
A device according to claim 1 wherein downstream of the point where said means for introducing said carbon dioxide introduces carbon dioxide into said by-pass line and upstream of the point where said by-pass line re-joins said main line said by-pass line has a portion comprising a plurality of bends.
Claim 4
Dependent Claim
28 words
A device according to claim 1 wherein downstream of the point where the by-pass line re-joins the main line the main line has at least one venturi nozzle.
Claim 5
Dependent Claim
36 words
A device according to claim 3 wherein downstream of the point where said by-pass line joins said main line said main line has a plurality of venturi nozzles disposed in series with respect to one another.
Claim 6
Dependent Claim
62 words
A device according to claim 1 wherein downstream of the point where said by-pass line re-joins said main line there is a means for determining the carbon dioxide content of the liquid in said main stream, said carbon dioxide determining means being connected to a controller which controls the amount of carbon dioxide introduced into said liquid while in said by-passing line.
Claim 7
Dependent Claim
35 words
A device according to claim 1 wherein said main line, downstream of the junction where said bypass line rejoins said main line, has an expanded portion with an annular channel for passage of the liquid.
Claim 8
Dependent Claim
49 words
A device according to claim 6 wherein in the direction of flow said expanded portion has a generally elliptical cross section and within the ellipse there is a flow splitting member disposed in such a manner that it produces a passage channel with annular cross section for the fluid.
Claim 9
Dependent Claim
19 words
A device according to claim 1 wherein said main line is in fluid communication with a source of beer.
