<p>Plant for the separation of undesirable substances from alimentary liquids, in particular from wine, which comprises a unit ( 3 ) with hydrophobic membranes ( 4 ) having holes ( 5 ) for trapping gas (G), supplied with wine to be treated (V) by means of first circulation means ( 6 ) and with an extraction fluid (L) having an alcoholic content substantially similar to that of the wine to be treated (V), by means of second circulation means ( 7 ). The two fluids pass along the two sides ( 4',4'' ) of the membranes ( 4 ), allowing the removal of the undesirable volatile substances which pass through the latter. The extraction fluid (L) is made to circulate by the second means ( 7 ) inside a purification circuit ( 8 ) which comprises a unit ( 9 ) for separation of the volatile substances, consisting preferably of an ion-exchange column. The process implemented in particular by the abovementioned plant envisages a step involving preparing the wine to be treated (V) inside a container ( 2 ), a subsequent step involving conveying to the abovementioned unit ( 3 ) and then a step involving removal of the undesirable volatile substances contained therein by means of evaporation, diffusion and consequent evaporation thereof which causes them to pass through the membranes ( 4 ) so as to be then evacuated by the extraction fluid (L) by means of ion-exchange resins, distillation, adsorption onto polymers or other system.</p> |
