The outlet tube being arranged for letting out a mixture of the liquid and the frothing gas, i.e. the liquid in a frothed state, and for letting out excess frothing gas. The chamber () is cylinder-shaped and the supply tube () has a tangential arrangement with respect to the chamber () and is provided at a height h from the bottom of the chamber. The ratio of the value of the height (h) of the supply tube and the height (H) of the chamber is in a range between 0.2 to 0.7, and the ratio of the value of the diameter of the outlet tube (d) and the value of the diameter (D) of the chamber is in a range of 0.6 to 0.95. This device provides for a high quality of milk froth without excessive or insufficient foam formation or very coarse foam bubbles.
