Abstract: A method and a device for air injection into a vinification tank (1) use air injection nozzles (2) installed therein. A rule is applied for automatic variation of injections with time, by a coordinated and combined action of the nozzles, so that for each of the installed nozzles the delivered air jets may be modulated in duration and frequency and combined with the jets delivered by the other nozzles according to a programmable sequence.

Abstract: An automatic apparatus for regulating and controlling the level of a liquid (1) in a tank (2) includes a liquid level detector (8). A vessel (3) associated with the tank (2) has a predetermined volume and is equipped with an upper closure (6) and with an open bottom (5) in communication with the interior of the tank (2) at a height below the level of the liquid (1). The automatic apparatus increases/decreases a liquid-free portion of the volume inside the vessel (3) and consequently transfers part of the liquid to/from the tank (2) through the bottom (5) in response to changes in the liquid level inside the tank (2) as detected by the liquid level detector (8).
