Device for foaming a liquid
A device for foaming a liquid includes a casing with a turbine arranged inside the casing. A shaft connects an agitator with the turbine. An air supply nozzle is coupled to the casing and a tube is coupled to the casing for conducting a steam supply to drive the turbine. A pipe is connected between the agitator and the turbine to introduce a steam-air mixture to a region of the agitator. The steam-air mixture is whirled together with the liquid when the agitator is immersed in the liquid.
1. A device for foaming a liquid, comprising:
a casing;
a turbine arranged inside the casing;
an agitator;
a shaft connecting the agitator with the turbine;
an air supply nozzle coupled to the casing;
a tube coupled to the casing for conducting a steam supply to drive the turbine;
a pipe connected between the agitator and the turbine to introduce a steam-air mixture to a region of the agitator, wherein the steam-air mixture is whirled together with the liquid when the agitator is immersed in the liquid; and
a holder, wherein the casing, turbine, agitator, and pipe comprise a unit that is positioned on the holder such that the unit is pivotable.
2. The device according to claim 1 , further including a ring-shaped cover with a plurality of flow-through openings located around the agitator.
3. The device according to claim 2 , wherein the cover includes a plurality of webs that define slanted flow-guidance surface relative to a radial direction for the rotational axis of the agitator.
4. The device according to claim 1 , wherein the agitator and the shaft are together removable from a portion of the casing for the turbine.
5. The device according to claim 1 , wherein the casing, turbine, agitator, and pipe comprise a unit that is vertically displaceable.
