The original canned fruit beverage, because it is heated during sealing, when the content is cooled, it will shrink and cause negative pressure inside the can, which will cause the tank to sink, so the tank wall is made thicker and more Liquid nitrogen can prevent this from happening, thereby reducing the wall thickness of the tank and saving the material.
In addition, after liquid nitrogen is filled in the fruit beverage cans, some air is eliminated, which is also advantageous for the storage of beverages. According to experiments, about 0.7g of liquid nitrogen is required for each can of beverage (in which, the liquid nitrogen in the actual sealed can is only 0.1g, and the others are vaporized during the filling process).
Japan Kirin Brewery Co., Ltd. produces a fruit beverage can filled with liquid nitrogen.
