Champagne Cooler

Warm Champagne – not any longer!

We all know this situation: There is something to celebrate, but the Champagne is not cold enough ...

To solve this situation, Zeo-Tech has developed two innovative Champagne Cooler Concepts with Zeolite Technology:

Concept 1:

Smart-Packaging Champagne Cooler for single use

Concept 2:

Rapid Champagne Cooler for double use

 

Concept 1:

Smart-Packaging Champagne Cooler for single use

Currently, Zeo-Tech is working on innovative developments in the area of “Smart-Packaging“. These are packaging units or packaging elements that have a self-cooling function and can be activated by pressing a button. In the following, a self-cooling packaging unit for Champagne bottles will be presented:


The single use cooler encloses the whole bottle. In separate sections of the foil cover, there are 250 g of Zeolite (yellow area) and 55 g of water.

With only two hand movements, the cooling can be started:

First step:


Press the start button.
After activating the button, 55 g of water is extended into the inside of the cooler around the bottle in a fleece cloth and evaporated under vacuum. Water vapour is sucked out of the zeolite filling and stored in its air cavities. Evaporation temperatures can drop to 0°C.
The zeolite is getting hot and the bottle cold.

For a maximum cooling capacity, the rise of the zeolite temperature has to be restricted. This means, the outer packaging surface in the area of the zeolite filling is coated with a yellow fleece cloth that is saturated with water.

Second Step:
The protective packaging around the saturated fleece cloth is stripped down. Water can now evaporate and the zeolite filling is kept at an optimum temperature.

While the water is evaporating, the bottle is cooled within a few minutes.

At the start of the cooling process, bottle content and ambient have a temperature of 26°C.The temperature of the bottle starts to drop. After approx. 20 minutes, the bottle content has reached a temperature of 10 °C. Therefore, the Champagne bottle could already be taken out of the packaging unit (single use cooler) after only 20 minutes. After further 10 minutes, the temperature drops below 7 °C. The lowest temperature lies at 4 °C and was taken after 70 minutes.

Conclusion:

With only 250 g of dry zeolite and the evaporation of 55 g of water, a bottle can be cooled down by 22 K and kept cold for more than 2 hours.

This remarkable invention is also - after Zeo-Tech’s development of a Self-cooling BeerKeg “CoolKeg”, a further highlight within the cooling/refrigeration technology.

For this development, Zeo-Tech is seeking licence partners.

Concept 2:

Rapid Champagne Cooler for double use

Zeo-Tech has developed a Champagne Cooler as an element of an innovative packaging concept. Here, the zeolite cooling technology is embedded into foils which consequently leads to an optimal cost-effectiveness. In two separate chambers (see photo below), there is each the exact water volume that is needed to cool down two Champagne bottles - one after the other - to drinking temperature with zeolite technology:

 

When crushing a water bag in one of the chambers, released water is then spread around the evaporator area, around the bottle from where it evaporates under vacuum-tight conditions and flows towards the zeolite. Now the placed Champagne bottle is cooled down via well attached walls of the evaporator area. Within 20 minutes, the system reaches an ideal Champagne drinking temperature of 8…12°C.

The Champagne Cooler for double use has been invented as an innovative component of a packaging unit that consists of a Champagne bottle, a Champagne cooler, two glasses and an outer packaging.
