Gas injection assemblies for batch beverages having spargers

A gas injection assembly for injecting a gas into a liquid to form a solution, the gas injection assembly comprising;

• a vessel configured to receive the liquid;
• a flow channel having an upstream inlet configured to receive the liquid from the vessel and a downstream outlet;
• and
• a sparger having a porous surface positioned in the flow channel, wherein the sparger is configured to inject the gas through the porous surface into the liquid to thereby form the solution;
• and
• wherein the downstream outlet is configured to dispense the solution back into the vessel.

A gas injection assembly for injecting a gas into a liquid to form a solution, the gas injection assembly comprising:

• a first vessel configured to receive the liquid, the first vessel having an open end and a closed end;
• a second vessel having an open end and a closed end;
• a top cap on the open end of the first vessel and having an intake passageway;
• an intake member defining a central bore and having a first end coupled to the top cap and a second end opposite the first end, wherein the second end is configured to receive the liquid from the first vessel and the first end is configured to dispense the liquid to the intake passageway, and wherein the second end is positioned in the first vessel and located nearer the closed end of the first vessel than the open end of the first vessel;
• a flow channel having a upstream inlet configured to receive the liquid from the intake passageway and a downstream outlet configured to dispense the solution into the second vessel;
• and
• a sparger having a porous surface positioned in the flow channel, wherein the sparger is configured to inject the gas through the porous surface into the liquid to thereby form the solution.
