Abstract: A process for obtaining clear must from grape berries includes feeding grape berries into a plant, controlled addition of adjuvant and/or clarifying substances to said grape berries while the grape berries are still at least partially intact, centrifuging said grape berries, in such a way as to separate the liquid phase or must from the solid phase with at least one centrifugal separator device, extracting and collecting the solid phase in a respective storage container and settling and/or flotation of the liquid phase or must so that the liquid phase of said must and the solid residue are separated.

Abstract: A plant is described for obtaining clear must from grapes including at least one centrifugal separator device with horizontal axis that is arranged to carry out a first separating operation, through application of a centrifugal force, between the liquid phase or must and the solid phase from the grape berries in solid state, and at least one tank for settling and/or flotation, either spontaneous or possibly promoted through injection of gas, said tank for settling and/or flotation being arranged downstream of the centrifugal separator device with horizontal axis, said tank for settling and/or flotation being configured to receive the must from such a centrifugal separator device with horizontal axis and being configured to carry out a second separating operation between the liquid part of the must and the respective solid residue or tank bottoms.

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.
