Abstract:
1. A frothing device adaptable to a steam outlet for producing milk froth comprising: a steam inlet, a milk inlet, an air inlet, a vacuum chamber adapted to receive steam, liquid milk and air therein, a restriction with a limited cross-section adapted for conducting a product there through at a high velocity, an emulsifying chamber of larger cross section than the restriction from which the product froth is emulsified, the emulsifying chamber having an outlet for draining the product froth out of the chamber in a first direction, downstream of the outlet is provided a froth flow regulation system which comprises a flow dampening member positioned in front of the outlet which is configured to break the kinetic energy of a froth stream and to redirect the froth stream in a second direction that is substantially opposite to the first direction so that the froth is gently delivered out of the flow regulation system downstream of the outlet of the emulsifying chamber; and wherein the flow regulation system is so constructed and arranged such that most of the kinetic energy of the froth drained from the outlet of the emulsifying chamber is lost by passage through the flow regulation system.
