Definitions

• the present invention relates to a refrigerating device for beverage.
• a refrigerating device for beverage There are numerous devices for refrigerating beverages at their ideal temperature of consumption, especially for sparkling wines, Champagne, whose optimum temperature of consumption is around 8 to 12 ° C, or strong alcohols such as vodka, cognac , etc., whose preferred consumption temperature may be negative (about -5 ° C to -10 ° C).
• Champagne are generally relatively thick glass bottles whose thickness is not constant over the entire bottle, which does not facilitate heat exchange and may lead to a non-uniform temperature of beverage.
• a cooling device comprises an enclosure inside which the bottle to be cooled is arranged.
• a cooling means is then introduced into the chamber.
• reaction should take place on contact with the bottle.
• Reactive products are likely to remain on the bottle which poses health and safety problems for the end user.
• Industrialists then turned to a gas path.
• Such devices include a gas cartridge under pressure in the liquid state. The gas is then injected into the enclosure where it relaxes and evaporates, then taking heat from the surrounding environment (enthalpy of vaporization) and in particular the liquid contained in the bottle which cools it. Vents allow evacuation of the gas.
• the pressurized gas can be injected and circulate through a coil surrounding the enclosure or directly into the enclosure, thus being brought into direct contact with the bottle which improves heat transfer and increases the cooling rate.
• these devices hardly meet clear objectives of efficiency, reproducibility and quality.
• these devices use a liquefied refrigerant gas tank.
• the amount of such gases used should generally be as low as possible for both economic and ecological reasons.
• it is necessary to maximize the heat exchange between the bottle and the liquefied gas so that the amount of gas to be evaporated is closer to the amount of heat that it is desired to remove the bottle to lower the temperature.
• the present invention relates to a method of cooling a container with a refrigerant gas comprising the steps of: placing the container inside a non-leakproof enclosure
• the gas flow rate is less than 90 m! per minute.
• the gas flow rate is less than 60 ml per minute.
• the gas flow rate is substantially equal to 45 - 50 mi per minute.
• the gas flow is greater than 30 - 35 m! per minute. Surprisingly, it has been found that it is not enough to simply inject a specific quantity of gas but that its injection rate is also an important parameter for obtaining a more homogeneous and more efficient cooling.
• the present invention also relates to a device for cooling at least one container, comprising an enclosure designed to receive said container and provided with at least one venting vent, said enclosure being furthermore equipped with minus means for admitting a liquefied refrigerant gas, characterized in that the intake means is configured so as to ensure an injection of the gas according to the method that is the subject of the present invention.

• At least a portion of the gas inlet means in the enclosure opens substantially to two-thirds from the bottom of the container, and in particular near a neck in the case of a bottle. Indeed, it has been found that an injection substantially at this level of a bottle ensures the best homogeneity of the cooling.
