Description

Technical Field

[0001] The present invention relates to the technical field related to beer packaging machines, and specifically relates to a pressure monitoring component inside an aluminum foil bag and a beer packaging machine. Background Technique

[0002] Beer is an alcoholic beverage brewed from wheat malt and barley malt as the main raw materials, added with hops, through liquid gelatinization and saccharification, and then through liquid fermentation.

[0003] The packaging methods of beer are usually divided into three types: bottled, canned, and bagged. Among them, the packaging costs of bottled and canned are relatively high, while the method of using aluminum foil bags for beer packaging is increasingly favored by beer manufacturers because of its low cost.

[0004] However, compared with bottled and canned, the pressure-bearing capacity of the aluminum foil bag is lower when using the aluminum foil bag for packaging. Therefore, when filling beer with an aluminum foil bag, it is necessary to monitor the pressure inside the aluminum foil bag during the filling process to avoid potential safety hazards caused by excessive pressure inside the aluminum foil bag due to factors such as filling rate. For this reason, the present invention proposes a pressure monitoring component inside an aluminum foil bag and a beer packaging machine to solve the above problems. Summary of the Invention
