DEVICE FOR FROTHING A LIQUID

摘要

Device (1) for frothing a liquid, comprising a chamber (10), which chamber comprises a supply tube(11) for supplying the liquid to be frothed and frothing gas, and comprises a substantially round outlet tube(12)provided at the bottom of the chamber. 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 (10) is cylinder- shaped and the supply tube(11) has a tangential arrangement with respect to the chamber (10)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.
