Device and method for producing a frothed liquid from soluble ingredients and diluent

A beverage production apparatus comprising:

• a device for producing a frothed liquid comprising an opened, cylindrically shaped chamber comprising a transverse bottom wall, a longitudinal upward wall, a first diluent inlet, at least one liquid delivery outlet, and a diluent feed means connectable to the first diluent inlet, the first diluent inlet extends through the upward wall and is inclined downwardly in a direction toward the bottom wall at an angle (b) relative to a transversal plane of the chamber to direct a jet of diluent into the chamber, and the liquid delivery outlet is located in the bottom wall for enabling liquid to rise up along the side of the upward wall by the jet of diluent entering the chamber,
• wherein the first diluent inlet is oriented in a direction so that a ratio of a distance “d” to the radius “r” of the chamber is between 0.2 and 0.9, and wherein “d” is a distance measured orthogonally from a direction of orientation of the first diluent inlet to a central axis of the chamber.
