Abstract
A method and equipment for the pressurized injection of air or other gases in a controlled manner into wine making tanks or similar for the purpose of efficiently breaking up the cap and extracting polyphenolic and aromatic compounds from the skins to the liquid portion (must) after the crushing of the grapes using the method for pumping over the grape harvest during the maceration thereof.
Claims11
A method for pumping over a grape harvest during maceration comprising:
- injecting pressurized air or other gasses in a controlled manner into a tank simultaneously striking at least two regions of a cap formed on a top portion of the tank by means for a pressurized injection of air or other gases by means of a compressed air distribution circuit located outside a tank wherein the means for a pressurized injection of air or other gases comprises at least two diffusers having gas outlets located at different heights or levels on a lower portion of the tank,
- wherein each of the at least two diffusers comprises an on-off valve connected to a compressed air distribution circuit,
- wherein an injection time during which each of the at least two diffusers introduces air or other gasses into the tank continuously comprises between 1 and 10 seconds,
- wherein a switching time elapsing between injection by each of the at least two diffusers comprises between 0.5 and 10 minutes,
- wherein a cycle rest time elapsing between an end of a pumping over cycle of each of the at least two diffusers and a start of the following pumping over cycle comprises between 90 and 720 minutes,
- wherein a cycle consists of actuation of each of the at least two diffusers sequentially, and
- wherein the injection time, the switching time and the cycle rest time are controlled through a microprocessor located outside of the tank, wherein the microprocessor controls the on-off valves of the compressed air distribution circuit through corresponding control circuits from solenoid valves or control valves installed in a junction box or control valve center.

A means for pumping over the grape harvest, comprising:
- a pressurized injection of air or other gases comprising at least two diffusers for the pressurized injection of air or other gases in a controlled manner into wine making tanks with gas outlets of the at least two diffusers located at different heights or levels on a lower portion of the tanks, wherein each of the at least two diffusers comprises an on-off valve connected to a compressed air distribution circuit,
- a microprocessor located outside of the tanks configured to control an injection time, a switching time and a cycle rest time by controlling the on-off valves of the compressed air distribution circuit through corresponding control circuits from solenoid valves or control valves installed in a junction box or control valve center,
- wherein the at least two diffusers are configured to inject air into the tanks, simultaneously striking at least two regions of a cap formed on a top portion of the tanks,
- wherein the injection time during which each pair of diffusers introduces gas into the tanks continuously comprises between 1 and 10 seconds, the switching time elapsing between injection by each of the at least two diffusers comprises between 0.5 and 10 minutes, and the cycle rest time which elapses between an end of a pumping over cycle of diffusers and a start of the following pumping over cycle comprises between 90 and 720 minutes under control of the microprocessor, wherein a cycle consists of an actuation of all the pairs of diffusers sequentially.
