Abstract: Equipment for yeast rehydration, in particular in dry, moist or in liquid dispersion form, which comprises a containment tank (2) closed by a cover (70) intended to receive a measured dose of yeasts to be rehydrated; first and second supply means (3, 4) adapted to respectively insert a rehydration liquid and nutritive substances in the tank (2); a circulation duct (14) placed in connection between at least one outlet opening (15) and at least one return opening (16, 16?) of the containment tank (2), intercepted by pumping means (17) for making the fluid mixture flow between the openings (14, 16). The equipment comprises means for insufflating air (32) inside the tank (2) susceptible for creating an over-pressure of a value that is regulated through suitable vent means (18).

Abstract: A method for tartaric stabilization, in particular for wine, and an apparatus for its implementation are provided. The wine to be treated is placed in a container and conveyed into a filtering unit. A permeated liquid is sent to a tartaric stabilisation unit for treatment. The tartaric stabilisation unit can operated by means of ionic exchange resins, electrodialysis or other separation processes. The treated liquid is reunited with a retained liquid at the outlet of the filtering unit to obtain a treated wine. Also provided are a cyclical operation of the apparatus and a cyclical method.

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.
