Abstract: A sprinkling device, particularly for processes for making wine from red grapes, which can be associated with a fermentation and/or storage tank in order to recirculate the wine must that is being fermented from the base region to the top region of the fermentation tank and to sprinkle the recirculated wine must in a stream into the top region of the fermentation tank, comprises: an auxiliary tank which can be fitted in a hatch or similar top opening of a main tank and which is provided with means for fixing to the hatch, first discharge means for the discharge of the wine must supplied to the auxiliary tank from the main tank, which means comprise a base opening of the auxiliary tank and a closure member which is movable between a closure position and an open position in order to produce a first sprinkling stream of the recirculated wine must, and second discharge means for the discharge of the wine must, which means are associated with the closure member and can discharge the wine must by means of a second

Abstract: An automatically operating fermentation vat for wine-making establishments includes a main vat (2), an upper vat (4) over the main vat, an uplift pipe (8, 12, 10, 24, 26) for feeding the fermenting liquid from the bottom of the main vat to the upper vat, means (16, 14, 18) for discharging this liquid from the upper vat into the main vat so as to spray the layer of marc floating in the main vat and injector means (20, 32) associated with the uplift pipe for injecting an oxygen-containing gas into the liquid flowing through the said pipe, characterized in that the uplift pipe has a first outlet aperture (24) directing liquid into the upper vat (4) and a second outlet aperture (40) which directs the liquid into the mass of liquid in the main vat, valve means (22) being associated with the uplift pipe for selectively directing the liquid into the upper vat or into the main vat or both at the same time though the two outlet apertures.

Abstract: Fermentation apparatus, particularly for wine-making, of the type comprising a main tank and a secondary tank, disposed on top of the main tank, having a lower opening for the discharge of the fermentation liquid into the main tank, and provided with a closure member movable vertically between a position for closure of the lower opening and an open position. Means for the output of jets of washing liquid are associated with the closure member in a manner such that the vertical movement of the closure member and of the washing means associated therewith enables the position of the washing jets to be adjusted.

Abstract: Automatically operating fermentation equipment: for winemaking of the type comprising:

Abstract: A fermentation tank particularly for plants for making red wine is described and comprises a main tank for holding the must, an upper tank disposed above the main tank, apparatus for periodically supplying a portion of the must from the bottom of the main tank to the upper tank, valve apparatus defining, with the base of the upper tank, an out-flow aperture the size of which is variable between a closed position and a fully-open position and which can discharge the must from the upper tank to the main tank so as to spray the layer of marc floating on the must held in the main tank, and actuator apparatus associated with the valve apparatus for the opening and closure thereof; the actuator apparatus comprise an electromagnetically operated actuator, a control and operating unit optionally being provided and arranged to define, by way of the actuator apparatus, the position of the valve apparatus and/or the rules governing the opening/closure movement thereof.
