The invention is directed to a device () and a process for dissolving a gas into a liquid like carbonating a water based beverage, comprising a pump () for the liquid, a mixing venture nozzle () with a main inlet () fluidly connected to the pump (), at least one side inlet () connectable to a source of pressurized gas (), and an outlet. The device () comprises also a conical flow restrictor () fluidly downstream of the mixing venture nozzle (), and a pipe () of a length of at least 0.5 m fluidly interconnected between the mixing venture nozzle () and the flow restrictor ().

In-line carbonation of water-base beverages

A device for the enrichment of a liquid stream with a gas is provided including a flow mixer () with a venturi nozzle (), having a rotationally symmetrical contraction () with a diameter D and being flown through axially by the liquid stream. The invention additionally includes a gas feed for the lateral feed of the gas into the contraction () of the venturi nozzle (). The gas feed includes at least one gas channel (') with a diameter d&#x3c;0.5D, ending laterally in the contraction () of the venturi nozzle () in a way, such that the elongated longitudinal axis (&#x2032;) thereof is tangential to an imaginary cylinder surface (), which is coaxial to the contraction () and has a diameter D&#x2032;&#x3e;d.

Device for the enrichment of a liquid stream with a gas

A pressure reducer includes a housing with an axially displaceable biased control body in order to close a connection between an inlet and an expansion chamber, where the housing is equipped with an axially displaceable biased actuating piston in order to displace the control body against the spring load of the control body as a function of the pressure in the expansion chamber and to open the connection, the housing being made of plastic, and the pressure reducer includes a separately made insert, where the insert is fixed between the inlet and the expansion chamber in the plastic housing and said insert has a guide bore, which is connected to the inlet and supports the control body, and a connecting bore, which adjoins the guide bore and which opens into the expansion chamber, where the insert forms an annular shoulder surface between the connecting bore and the guide bore, said shoulder surface interacting as a seating surface with the seal on the control body.
