Stainless Steel 20L Kegs
These kegs are highly coveted because of their durability and rust-resistant. In addition to this, the stainless steel construction enhances the value of the 20l kegs because it keeps the content safe. Also, the material guarantees that the contents of the keg are either beer, cider, or any soft drink for external elements and contaminants. In short, stainless steel is suitable for both the brewery and event rental businesses due to its long lifespan and reusability.
Rubber-Coated 20L Kegs
Rubber-coated kegs provide an additional layer of protection to the stainless steel underneath. They ensure the keg does not dent or break easily when it is dropped or knocked over. This coat also acts as insulation for products that are sensitive to temperature changes. Thus, rubber-coated 20-liter kegs are ideal for breweries and other companies that wish to reduce the risk of damage to their equipment or stock.
Cornelius 20L Kegs
Cornelius kegs, or Corny kegs, are more popular with the home brewer and small operations. They can also be called adjustable post kegs easily to attach different types of posts to the liquid and gas sides. Most Cornelius kegs have a capacity of 20 liters, which makes them useful for smaller batches of beer, soda, or other beverages. They are also quite modular and can be used for a variety of product storage and dispensing applications.
Chrome-Plated 20L Kegs
Chrome 20L kegs are often used in the hospitality industry due to their attractive finish. If given an opportunity, all owners would want to have their kegs chrome plated because of the aesthetic value it provides. However, while chrome kegs are visually appealing, the plating can wear off over time if not properly maintained. Nevertheless, these kegs still make a great option for restaurants or bars wishing to enhance the visual appeal of their beverage service.
Aluminum 20L Kegs
Aluminum kegs are lighter than stainless steel. Unfortunately, they also cost the user some extra dent, and they are not as durable. Nonetheless, these kegs can be an economical option for companies that require a keg that can be used on a temporary basis. One advantage of aluminum kegs is that they can be used with anodes to provide resistance to corrosion.
Considerations for Design
The design of a 20L keg depends on several factors. They include intended use, desired materials, and required performance features. Some of these features may be important for enhancing product quality or even included for aesthetic purposes. Here are some design elements that must not be overlooked when designing a 20-liter keg:
Valves and Fittings
The design of the valve and the keg's fitting is important and, most importantly, must ensure that the contents are properly sealed. One of the common fittings is the Sanke D System since many manufacturers use it. Other styles include pin lock and ball lock configurations. These valve types determine how the keg should be used to dispense or recharge the beverage inside. Therefore, before anything else, users should match the valve and fitting design with their dispensing systems. This will ensure seamless compatibility.
Internal and External Coatings
Kegs used to store sensitive liquids, particularly food and drink, may need to be coated to improve safety or quality. Common coatings include epoxy or FDA-approved linings that help prevent contamination and corrosion. These coatings are helpful in maintaining the purity of the keg's contents, particularly in beverages that are prone to chemical reactions with metal. Also, there are external coatings to help improve aesthetics or provide increased protection against impacts or corrosion.
Keg Pressure and Capacity Design
This is where the designer uses the interplay between pressure and capacity to ensure that the keg can effectively contain the liquid under normal operating conditions. Most commonly, kegs are pressurized during filling to help keep the liquid carbonated and extend shelf life in beverages. The 20-liter size, of course, provides a large enough volume that makes it ideal for commercial applications.
Ease of Use Features
Designers should consider incorporating Sanke coupler slots, uncomfortable handles, and stacking features into the design of the keg. These features make it easy to transport, store, and connect to the beer dispensing system for draft beer in the bar or restaurant. Other ease-of-use considerations include replacing parts and serving, maintaining, and cleaning.
Shape and Portability
Since kegs are sometimes moved by hand or with carts, the shape and overall weight should provide easiness. Cornelius kegs may have curved bodies for easier grip and carts for portability.
Brewery Operations
Brewery companies use the 20L keg system for storing and dispensing their beer or other brewed products. Because of its size, it is perfect for either large-scale operations or small boutique breweries to use to serve to their customers or supply to other businesses. All large breweries will use kegs in tightly controlled environments to ensure consistent quality and easy product tracking. Plus, the 20-liter size makes it possible for efficient rotation of stock and ensures workers do not have to change kegs frequently.
Bars and Restaurants
These places use kegs in their draft beer systems. They all prefer the 20L size because it is conveniently large enough to reduce the frequency of required replacement but is not too huge that it becomes cumbersome. Kegs used in bars and restaurants are managed to make sure that beer quality is preserved while making it easy for the customer to enjoy great-tasting beer. Other small pubs and restaurants that do not have draft beer systems can use their kegs to dispense soda or other beverages.
Event Catering
Catering companies who are hired for large outdoor events and receptions use 20-liter kegs to guarantee that there will be enough beer, wine, cider, and soft drinks for the guests. The kegs are perfect because they can easily be transported, are easy to set up and use, and are rugged and durable. They also make them simple to integrate into portable bar systems.
Homebrewing
Only people who brew their own beer will be able to use Cornelius kegs. Since homebrewing is not common for many users, only a small percentage will own Cornelius kegs and use them for beer storage and dispensing. Still, those homebrewers who own a Cornelius keg will use it. They may enter their homebrew into competitions or just store it for personal consumption. They also offer a means to carbonate homemade beverages.
Industrial and Chemical Storage
Apart from its purpose in beverage processing, kegs can also be used to store or transport various chemicals and industrial liquids. For such applications, the Keg must be constructed out of either aluminum or stainless steel, as these materials are resistant to chemical corrosion.
To ensure longevity and optimal performance, it's essential to pay attention to specifications and maintenance routines for 20L kegs.
Technical Specifications
Key specifications for 20L kegs include material type, dimensions, valve configurations, and internal pressures. Most Kegs are made of either stainless steel or aluminum, with the former being more durable. Each 20L keg can have a variety of valve styles and configurations, depending on the particular use or need. A key compatibility factor, especially for draft beer systems, is the valve design. Last but not least, Kegs are usually designed with a specific internal pressure rating to ensure the safe retention of carbonated liquids, particularly beverages. Common pressures range between 2.5 to 4 bars.
Regular Maintenance Tasks
The maintenance of the kegs goes as follows: Regular inspection means looking for corrosion, dents, and other signs of wear and tear. Cleaning is important to remove any leftover residues to wash out contaminants and deposits inside. This is where cleaning solutions or simply warm, soapy water are used. Sanitizing usually involves using a commercial sanitizer or a bleach solution to kill any possible remaining bacteria before refilling or reusing the keg.
Seasonal Maintenance
Seasonal maintenance may involve deep cleaning, checking the keg for faults, replacing worn-out parts such as seals and gaskets, and putting away kegs in safe storage for winter.
Storage and Preservation Guidelines
It is important to store kegs in a cool, dry, and sheltered area to avoid direct sunlight. This slowly deteriorates the rubber seals and other coating elements. In addition to this, a space that has controlled temperatures will prevent warping or bending the metal as the seasonal temperatures change.
Choosing Components
The choice of components in the keg—its valves, seals, and fittings—will impact both the performance and the ease of maintenance. For ease of maintenance, it's better to go for kegs with commercially available spare parts for ease of maintenance.
