Abstract
The invention is directed to a device (1) and a process for dissolving a gas into a liquid like carbonating a water based beverage, comprising a pump (4) for the liquid, a mixing venture nozzle (8) with a main inlet (10) fluidly connected to the pump (4), at least one side inlet (14) connectable to a source of pressurized gas (6), and an outlet. The device (1) comprises also a conical flow restrictor (24) fluidly downstream of the mixing venture nozzle (8), and a pipe (20) of a length of at least 0.5 m fluidly interconnected between the mixing venture nozzle (8) and the flow restrictor (24).
Claims19
A device for dissolving a gas into a liquid, comprising:
- a pump configured to pump the liquid;
- a mixing venturi nozzle having a main inlet fluidly connected to the pump and at least one side inlet connectable to a source of pressurized gas, and an outlet;
- a conical flow restrictor fluidly downstream of the mixing venturi nozzle, comprising a body and a conical element housed in the body, a gap being provided between an external surface of the conical element and an internal surface of the body, said gap forming a flow section for the liquid, the conical element comprising a plate-shaped end abutting the body and provided with apertures for permitting liquid to flow to an outlet on the body;
- and
- a pipe fluidly interconnected between the mixing venturi nozzle and the flow restrictor.
A process for dissolving a gas into a liquid, comprising:
- providing a circuit having a mixing venturi nozzle;
- pressurizing the liquid in the circuit;
- adding the gas to the liquid flowing through the mixing venturi nozzle by connecting at least one side inlet of the venturi nozzle to a source of the pressurized gas;
- providing a conical flow restrictor fluidly downstream of the mixing venturi nozzle, comprising a body and a conical element housed in the body, a gap being provided between an external surface of the conical element and an internal surface of the body, said gap forming a flow section for the liquid, the conical element comprising a plate- shaped end abutting the body and provided with apertures for permitting liquid to flow to an outlet on the body;
- and
- fluidly interconnecting a pipe between the mixing venturi nozzle and the flow restrictor.
