(1) Vacuuming: the bottle and the centering cover are tightly pressed onto the filling valve, and the vacuum valve is pushed open by a fixed stopper. In a short time, the vacuum degree in the bottle can reach 90%.
(2) CO2 filling: by operating the handle of the butterfly valve (roller), the CO2 gas valve is opened for a short time, so that CO2 can be introduced into the bottle from the wine jar; This process is very short, and it will end when the handle of a butterfly valve (roller) is reset; At this time, the pressure in the bottle rises to near atmospheric pressure.
(3) Secondary vacuuming: the first step is repeated, and about 90% vacuum degree is obtained again. As the mixture of the air left after the last vacuuming and CO2 is pumped out this time, only about 1% of the air in the bottle is left after this step.
