Device for the controlled injection of air into a winemaking tank and winemaking tank provided with said device

摘要

Vinification tank equipped with a device for injecting air or inert gas into the vinification tank (1), wherein the device for injecting air or inert gas comprises: - an air or gas distribution circuit inert (3), - at least three nozzles (2) for the injection of compressed air or compressed inert gas, supplied through the distribution circuit (3), said nozzles (2) being mounted on said tank (1) to a level (h) from the bottom of the tank (1) not higher than one third of the total height of said tank (1), and said distribution circuit (3) including a separate supply line for each nozzle, where : the control valves (4) of air or inert gas flow to each nozzle (2) are present in said distribution circuit (3), each of the control valves (4) being present in the line of respective supply of the distribution circuit (3); and the microprocessor means (11) are configured to act on the control valves (4) and are programmed to actuate said control valves (4) independently of one another, characterized in that the microprocessor means are programmed to control a delivery of air or inert gas from each nozzle, changing the duration and frequency of the air or gas jet over time, according to a specific predetermined modulation, and the delivery sequence of all nozzles that activate the nozzles one behind the other or in a partially overlapping way, or at the same time, with the same or different durations and frequencies
