The device has a foodstuff feed line (4), a steam feed line (7) and an air feed line (8) connected to a foaming chamber (5) in a fluid-conducting manner. A control unit (9) controls an intermittent air valve (10) of the air feed line, where the control unit switches the air valve between a high air flow state and a relatively lower air flow and/or airless state. The control unit and the air valve have an interacting construction such that the average air flow of the air valve is controlled by repeated switching between the two states of the air valve. An independent claim is also included for a method for foaming a liquid foodstuff. |
