Abstract

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.
