In-Line Carbonation of Water-Base Beverages

A device for dissolving a gas into a liquid, comprising:

• a pump configured to pump the liquid;
• a mixing venture nozzle having a main inlet fluidly connected to the pump and at least one side inlet connectable to a source of pressurized gas;
• an outlet;
• a conical flow restrictor fluidly downstream of the mixing venture nozzle;
• and
• a pipe having a length of at least 0.5 m fluidly interconnected between the mixing venture nozzle and the flow restrictor.

A process for dissolving a gas into a liquid, comprising:

• providing a circuit having a mixing venture nozzle;
• pressurizing the liquid in the circuit;
• adding the gas to the liquid flowing through the mixing venture nozzle by connecting at least one side inlet of the venture nozzle to a source of the pressurized gas;
• providing a conical flow restrictor fluidly downstream of the mixing venture nozzle;
• and
• fluidly interconnecting a pipe of a length of at least 0.5 m between the mixing venture nozzle and the flow restrictor.
