Wine Aging in Pressure Vessel with Spring Return Cork

The patent applies parameter changes by subjecting the wine to elevated pressure conditions (e.g., 3-10 times atmospheric pressure) and controlled temperature fluctuations within a pressure vessel. These parameter modifications accelerate the chemical reactions and physical processes involved in wine aging, enabling the wine to reach peak maturity much faster than under normal storage conditions, thus resolving the contradiction between quality improvement and time loss.

The patent employs periodic action through cyclic pressure changes and temperature variations in the aging process. The wine is subjected to repeated cycles of pressurization and depressurization, along with temperature fluctuations, which simulate and intensify the natural aging process. This periodic stimulation accelerates maturation while maintaining wine quality, effectively reducing the required storage time.

The patent uses an inert or controlled atmosphere within the pressure vessel to prevent contamination during accelerated aging. The vessel is sealed and maintains a controlled environment that excludes harmful external factors such as seawater, contaminants, and microorganisms. This allows the wine to be aged rapidly under elevated pressure and temperature conditions without introducing contamination, thus resolving the contradiction between aging speed and contamination prevention.

The pressure vessel acts as an intermediary between the wine and the external environment. It provides a controlled medium that enables accelerated aging through pressure and temperature control while simultaneously protecting the wine from harmful external contaminants. This intermediary structure allows the benefits of unconventional aging methods to be achieved without their associated risks.

The patent replaces complex mechanical cork securing mechanisms with a simpler approach using elastic bands or rubber bands placed around the bottle neck. This substitution maintains the necessary function of preventing cork intrusion while significantly reducing device complexity. The elastic bands provide sufficient restraining force to counteract cork movement during pressurization without requiring complex mechanical systems.

The patent employs simple, inexpensive elastic bands that can be easily applied and removed as a temporary measure during the aging process. These disposable or reusable elastic bands serve their purpose effectively during pressurized aging and can be discarded or replaced, avoiding the need for complex, expensive, or permanent cork securing mechanisms while preventing wine adulteration.
