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.
A fermentation tank, particularly for plants for making red wine, comprising a main tank for holding the must, an upper tank disposed above the main tank and having a discharge opening in its base, means for periodically supplying a portion of the must from the bottom of the main tank to the upper tank, valve means defining, with the discharge opening 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 means associated with the valve means for the opening and closure thereof, wherein the actuator means comprise an electrically operated actuator, a control and operating unit being provided and arranged to define, by means of the actuator means, the position of the valve means and/or the rules governing the opening/closure movement thereof.
