One of the most essential thing about the bottling as well as kegging process is to keep the beer from being polluted by stray yeasts, as well as to maintain oxygen far from the beer. These are the main things that can reduce the shelf-life of beer.
The manner ins which the beer is moved into containers and kegs is pretty similar; but bottling has a couple of additional actions, so we'll discuss bottling.
To start the process, the empty bottles are packed onto the bottling line, where they are first washed with a chlorine service, and then blasted with carbon dioxide to eliminate the solution.
Next, the containers enter a turret-like mechanism that can hold 12 containers simultaneously. Each bottle trips around the turret once. During its flight, the container is purged with CO2 numerous times prior to it is loaded. The bottles are pressurized with carbon dioxide to ensure that when the beer is pushed into the bottles under pressure it does not foam up way too much. After the beer has been included in the bottles, the pressure is gradually soothed until the beer is at ambient pressure. As each filled up bottle leaves the turret, a vacant one takes its place.
Next comes the covering device-- now there is a little bit of air space at the top of the container that needs to be purged. To do this, the container is passed under a really narrow, high-pressure jet of water that hits the beer, causing it to foam up and also drive the air out of the bottle. The cap is then applied prior to any type of air can return to the bottle.
After the cap is used, the beyond the container is washed to remove any kind of beer that might have lathered out throughout the process.
Surprisingly, one of the most tough part of the bottling procedure is using the label to the container. Getting a tag to adhere to a chilly wet beer bottle is no easy technique.
The labels are fed into the labeling device, which has a spinning device that rolls adhesive onto the tags and after that sticks them to the containers as they pass by. If all works out, the label will be appropriately placed, smooth as well as well-adhered.
A special inkjet printer sprays the day onto the tag as it passes the print head. The day the beer was bottled as well as likewise a "finest prior to" day (three months after the bottling day) are published on the label.
Next off, the bottles get in a turret-like mechanism that can hold 12 containers at when. The containers are pressurized with CO2 so that when the beer is forced into the containers under pressure it does not foam up also much. To do this, the container is passed under a very narrow, high-pressure jet of water that strikes the beer, creating it to foam up and also drive the air out of the container.
