Abstract
Device for foaming a liquid comprising a mixing unit (). The mixing unit () comprises a first element () having an inner surface (), a second element () having an outer surface (), a gap () between the inner surface () of the first element () and the outer surface () of the second element (), a first opening () and a second opening () connected through the gap (). At least one of the first element () or the second element () is rotatable about an axis of rotation (AR) with respect to the other one. The inner surface () and the outer surface () are symmetric with respect to a common axis of symmetry (AH, AW), coincident with the axis of rotation (AR), and have circular sections, perpendicularly to the axis of symmetry, having diameters which increase going in a direction along the axis of symmetry (AH, AW).
