Device for instant cooling of liquids, beverages and food

Abstract

Device and system for producing instant cooling, particularly for lowering the temperature of liquids and beverages contained in bottles. The same device can be used, by means of appropriate positioning of the diffusers in specific trays, for cooling foods. Moreover, the diffusers appropriately positioned in insulated containers act as portable refrigeration cabinet for foods, beverages and any product or material that requires to be preserved at low temperatures. The particular characteristic consists in the fact that the device makes use of a container having parts suitable to be filled with gas. Said container has one part acting as a chamber which stores the dry ice formed by the gas and one part made of sintered metal through which heat exchange is triggered when in contact with the product to be cooled.
