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.
Claims20
A method treatment of grapes comprising:
- providing a vinification tank with a gas injection device having:
- at least three nozzles for the injection of compressed gas into the vinification tank,
- a distribution circuit including a separate supply line for each nozzle,
- control valves on said distribution circuit for controlling gas flow to each nozzle, each of the control valves being present on the respective supply line of each nozzle;
- independently actuating the control valves and cause injection of compressed gas in the form of a plurality of gas pulses which are injected into the vinification tank through each one of said at least three nozzles,
- wherein said injection of compressed gas in the form of gas pulses comprises a cycle of gas injection through each nozzle, each cycle of gas injection comprising gas pulses through each nozzle,
- wherein the nozzles are activated in sequence with the at least three nozzles starting respective cycles of gas injection in turn, one after the other, such that cycles of subsequently activated nozzles are partially overlapping over time.

A method treatment of grapes comprising:
- providing a vinification tank with a gas injection device having:
- at least three nozzles for the injection of compressed gas into the vinification tank,
- a distribution circuit including a separate supply line for each nozzle,
- control valves on said distribution circuit for controlling gas flow to each nozzle, each of the control valves being present on the respective supply line of each nozzle;
- inserting crushed red grapes into the vinification tank,
- allowing grape skins to separate from liquid to form a compact layer cap above the liquid,
- independently actuating the control valves and cause injection of compressed gas in the form of gas pulses which are injected into the vinification tank through each one of said at least three nozzles,
- wherein said injection of compressed gas in the form of gas pulses comprises a cycle of gas injection through each of said at least there nozzles, each cycle of gas injection comprising gas pulses through each nozzle,
- and wherein the cycles of gas injection through the at least three nozzles form waves in the liquid which break the cap, flooding it with liquid.
