aisber1The process consists of a solution of salts in water it requires energy, in the form of ambient heat.

Young chemistry, Paola Fatas, He has developed a cooler for cans and bottles 33 centilitres that does not need electricity or ice.

This innovative and environmentally friendly product, called Aisber, It has already been released to the market by the company Cool everywhere, una ‘start up’ University of Zaragoza.

Aisber works by a solution of salts in water, which mixture is cooled in seconds reaching temperatures close to 0 ° C. It's components, mainly urea and water, let cool the beverage, standing inside the cylinder, up to 20 degrees in less than 10 minutes anywhere. The mixture is kept cold for half an hour.

Aisber is formed in the inner part by grants with separate cavities, containing liquid and salts. Pressing on the cavity containing liquid, seal separating the two cavities is opened, producing the mixture of components active cooling.

“We have developed a manufacturing technology that enables rapid cooling and effective at a competitive price”, He said Paola Fatás, Honors Degree in Chemistry and a PhD in Organic Chemistry from the UZ since June 2012.

aisber2A bike path on a hot day made Fatás began investigating because it seemed “amazing” that did not exist a product that did lower the temperature of the drink that could be used anywhere.

Processes salt solution in water are very common and observed daily every time we add salt or sugar to food or drink.

In many cases, salts solution leads to an increase or decrease in temperature although, using small amounts, we do not realize.

Sometimes, even without being aware, increase the energy of the system to facilitate dissolution, either by stirring with a spoon or by heating the mixture.

The cooling process inside Aisber It occurs instantaneously at the time when the components are mixed, reaching temperatures close to 0. By placing the drink inside the cooler, it comes into contact with the mixture being cooled.

After activation, the mixture is kept cold around 30 minutes, preventing the hot beverage during consumption.
