Canned beer

Abstract

The invention relates to a canned beer, which comprises a can and beer in the can. Wherein, it is characterized in that: the bear inside the can contains liquid nitrogen container filled with liquid nitrogen; the container has the air hole of nitrogen; when canning the beer, the liquid nitrogen ball is put in, therefore, part liquid nitrogen will contact the air to be transformed into nitrogen gas, to discharge the air at the top of can, to prevent beer being oxidized; when the can is opened, the liquid nitrogen will be gasified to be discharged via the air hole, to generate bubbles.

Description

technical field [0001] This invention relates to beer, and more particularly to finished beer in a container. Background technique [0002] The internal volume of containers such as cans / bottles containing beer is greater than the amount of beer to be filled, so there will be a gap after the beer is poured into the container. This part of the void will be filled with air and CO 2 Occupied by the mixture, and the amount of gas in it is called the bottleneck air. [0003] Taking a 640mL glass bottle as an example, the inner volume of the bottle is 670mL, the effective volume of filling is 640mL, and the gap in the neck of the bottle is 30mL. If all of it is occupied by air, the air content in the neck of the bottle is about 30mL, which is equivalent to 8.4% oxygen. mg, if all dissolved in the beer in the bottle, the dissolved oxygen concentration for 640mL beer is 13.125mg / L, and the concentration of oxygen that affects beer is 0.5mg / L, exceeding 2mg / L, that is, the stabilit...
