A device (3) for frothing a liquid comprises a first space (10) having an outlet (11) for allowing content from the space (10) to flow out of the space (10), means (40) for supplying the liquid to be frothed to the first space (10), and a second space (50) for allowing the liquid to mix with a gas in order for a frothing process to take place. The second space (50) is open to the first space (10), and has an inlet (51) for receiving content from the first space (10), which is separated from the outlet (11) of the first space (10) by a free space (60) for containing the frothing gas. At the position of this free space (60), when the device (3) is operated and frothing gas is present, the frothing gas is allowed to flow into the second space (50).
Device for frothing a liquid, comprising a first space having an outlet for allowing content from the space to flow out of the space, means for supplying the liquid to be frothed to the first space, and a second space for allowing the liquid to mix with a gas in order for a frothing process to take place, wherein the second space is open to the first space, and has an inlet for receiving content from the first space, which is separated from the outlet of the first space by a free space for containing the frothing gas and for allowing for a supply of the frothing gas to the second space under the influence of a flow of liquid from the first space to the second space, characterized in that the device further comprises means for pumping the liquid towards the outlet of the first space, wherein the pumping means comprise means for supplying a fluid to the first space, which are connected to the space through a constriction.
