Packaging is a very crucial aspect of producing beer.
It not only preserves quality and freshness but also presents the brew in an attractive manner.
Among the many different methods of packaging, one of the most used is kegging.
This method allows a considerable quantity of beer to be packed into one container.
Kegging plays an integral part in this process, whereby a beer kegging machine provides automation to the otherwise labor-intensive jobs of filling, cleaning, and maintaining kegs.
This article will explain in depth the important role kegging plays in beer production, how keg machines, or keg lines, work, and their differences, so as to present options for your brewing operation.
WHAT IS A BEER KEGGING MACHINE?
A kegging machine is that special piece of equipment that helps one in automatic filling and sealing of beer into kegs.
Kegs are great big, reusable containers that enable brewers to package and distribute their beer in bulk lots.
Be it for commercial breweries or the smaller, craft operations, kegging systems will be required to preserve freshness in the beer and allow easy distribution.
Kegging is the final stage before reaching the consumer and is followed after fermentation, filtration, and carbonation of beer.
This process, in general, consists of two major phases: washing of the keg by cleaning and sterilizing, and filling the keg by transferring beer into the clean keg.
The kegging machine is designed to provide ease in the process, save time, minimize waste, and enhance consistency.
BENEFITS OF USING BEER KEGGING MACHINE
Automating the kegging process through a kegging machine can bring a number of benefits, especially one intending to scale up operations or improve efficiency.
Efficiency: Kegging machines reduce the total time spent filling and cleaning kegs; thus, brewers can package more beer in less time.
This is pretty helpful for huge breweries that feel the pinch of trying to keep up with high demand.
Consistency: Machines ensure that kegs are precisely filled, hence avoiding under or overfilling and further ensuring that all kegs have the same volume of beer.
Consistent fills will also maintain proper carbonation levels; this will be crucial in retaining the taste and quality of beers.
Sanitation: Cleaning and sterilization are very important to avoid any chance of contamination.
Kegging systems, or keg lines, with functions for washing ensure that every keg is cleaned at extreme depth before it gets filled.
This limits any probable chance of spoilage or off-flavors of the beer.
Labor Savings: Automating kegging operations means not too many people are required to do manual cleaning and filling of kegs, hence saving labor costs and freeing more time for workers to attend to other pressing matters in the brewery.
DIFFERENT TYPES OF KEGGING MACHINES
There are lots of different kegging systems designed for any given need; from keg cleaning to keg filling to the dispensing of beer.
Some of the more common types of beer kegging machines and systems are described below.
- Keg Washing Machine
- Keg Filling Machine
- Kegerator and Keg Dispenser
- Mini Keg Machine
- Combination Keg Washer and Filler
Let’s take an in-depth look at each one to understand its role and importance.
KEG WASHING MACHINE
This step is important because left-over materials, bacteria, or yeast from previous batches in the keg can contaminate the fresh beer.
Keg washers have commonly between three and five cycles: a rinse cycle to remove the remaining beer; detergent cycle to eliminate heavy residue; and sterilization cycle through steam or chemical sanitizers to sanitize the keg.
Automatic keg washing machines are ideal for large breweries, because several kegs can be cleaned at a time, which speeds up cleaning significantly.
KEG FILLING MACHINE
Examples of keg filling machines are made for transferring beer from storage tanks or fermenters into the cleaned kegs.
Precision controls are part of their build so that each keg is filled precisely to the right level to maintain proper carbonation and cut down on spillage or waste.
Most keg filling machines have adjustable settings for accommodating different sizes of kegs.
They are thus versatile to handle a myriad of different formats.
More importantly, this machine will be helpful to those breweries offering their beers in a couple of keg sizes.
Advanced models possess integrated CO2 purging systems.
They remove oxygen from the keg before filling.
This method reduces the risk of oxidation, hence preserving freshness of beer.
KEGERATOR AND KEG DISPENSER
A kegerator is simply a refrigerator that is designed to house and serve kegs of beer.
They can be found in bars, restaurants, and even in the homes of enthusiasts who like their fresh draft beer at the pull of a tap.
While they are not technically part of the kegging process on the brewery side of things, they are necessary in serving the beer once it has been kegged.
Kegerators have built-in taps and CO2 regulators to allow the beers to dispense at the right pressure and temperature.
The sound keg dispenser ensures freshness with each serving and proper carbonation for the brewer and bartender alike.
MINI KEG MACHINE
Mini keg machine would be great for the small-scale brewer or the homebrewer desiring to enjoy draft beer without the full-size keg commitment.
Most of the mini keg systems employ 5-liter kegs, which make them even more portable and easier in handling.
They generally include a so-called CO2 dispenser or pump for carbonation purposes.
While more lowly represented in the high-capacity use that commercial kegging systems are, they suffice for personal use and small group entertainment.
COMBINATION KEG WASHER AND FILLER
The keg washer and filler can be combined into a single unit for automation of both the cleaning and filling processes.
This machine will work for breweries that want to make their kegging process more efficient.
Brewers will save much time in keg preparation by housing both functions in one unit, hence assuring faster turnarounds.
Combination machines generally have separate chambers for washing and filling, and the entire process can be programmed and monitored through digital controls.
This kind of machine is particularly useful for medium to large breweries where there is a high volume of kegs that need to be processed.
CONCLUSION
Kegging machines are among the important machines that help modern breweries package their beers efficiently, with high standards of quality and sanitation.
Whether it’s a large brewery operation or a small craft one, finding the right kegging system can make all the difference in your production process.
From very important keg washing machines, which clean, to the highly accurate and efficient filling by the keg filling machines, there is something different that each has to offer.
The Kegerators and keg dispensers ensure that the final product is enjoyed at its best, while mini keg machines bring the kegging experience to smaller operations or homebrewers.
And for those looking to simplify the overall process of kegging, combination keg washers and fillers provide a little bit of both worlds.
Picking the right kegging system for your brewery is far more than a question of convenience: it’s about making sure that every pint of beer that goes out of your brewery is as fresh, full-bodied, and delicious as possible.
