Abstract
A milk foaming device for emulsifying steam, milk and air to produce foamed milk. The milk foaming device includes an ingredient combining assembly for combining the steam, milk and air connected to a swirl chamber for blending the ingredients. A discharge tube is attached to the swirl chamber for dispensing foamed milk therethrough. A concave notch is formed in the walls of the discharge extending from a dispensing port of the tube upwardly along the walls. The notch retards or prevents formation of bubble surfaces over the dispensing port of the discharge tube and thereby prevent splattering of milk. A laminator is provided in the tube and extending therefrom for inducing a columnar flow of foamed milk from the discharge tube.
