Milk frothing system (1) including a water conduit (10) that successively interconnects a water reservoir (11); a pump (12); a heater (15), configured to evaporate water; and a mixing node (31). The system further includes an air conduit (20) that successively interconnects an air inlet (21); a first check valve (22); a second check valve (24); and the mixing node. The system also includes a steam/air conduit (30) that successively interconnects the mixing node, and a frothing device (32). The milk frothing system additionally includes an expansion vessel (60), having a water chamber and an air chamber, said water chamber being connected to a point of the water conduit, downstream of the pump and upstream of the heater, and said air chamber being connected to a point of the air conduit, downstream of the first check valve and upstream of the second check valve provided therein. |
