Abstract
A device for putting in solution a powdery concentrate includes a liquid supply pipe (), an extraction pipe () with a valve (), and a transfer pipe () connected to a junction point, the transfer pipe being for connecting to a receptacle () containing the concentrate. The junction point is in the constriction of a venturi tube (), the supply pipe () being connected to the convergent chamber () and the extraction pipe () to the divergent chamber (). If the valve () is closed, the liquid leaves the venturi tube through the vacuum tapping to enter the receptacle. When the valve () is opened, the liquid leaves the venturi tube through the divergence chamber, causing a pressure drop in the vacuum tapping. The saturated liquid contained in the receptacle is then sucked and entrained by the liquid passing through the venturi.
