Abstract

The device (1) contains a first chamber (3) in which a gas is mixed with a liquid. The first chamber (3) is of tubular shape and leads into a second chamber (4) which contains a channel (16) in the form of a gap in which turbulent flow is generated in the liquid/gas mixture. The foam is thus homogenised before it emerges from the outlet (17) of the second chamber (4). <IMAGE>
