Step 1: Loading the Machine with Empty Cans

The process starts with rows of empty cans. Depending on the brewery or copacker’s canning machine, the cans may be fed into the machine in two ways:

Automatic canning: In a high-output automated system, a depalletizer is used to load the empty cans onto a conveyor belt in groups.
Manual canning: For manual or semi-automatic systems, the operator must feed each empty can into the machine by hand.
Regardless of the method, the empty cans arrive on the conveyor belt without tops, ready to be filled. In some cases, copackers may use pre-printed cans to skip the labeling step, but most of the time, the cans are blank, with labels added later.

Step 2: Rinsing the Interiors of the Cans

The cans are thoroughly washed before filling, whether they are brand new or recycled. They travel down a conveyor belt and into a twist rinser that looks like a rollercoaster for cans. The twist rinser flips the cans upside down and blasts them with sanitizing water, cleaning the interiors, before returning the cans to their upright position.

Step 3: Purging the Oxygen

As the cans are open, they are full of oxygen and residual water. To remove this, carbon dioxide (CO2) is pumped into each can to purge the oxygen and prevent it from affecting the beer’s flavor and shelf life.

Step 4: Filling the Cans After purging the oxygen.

The cans are ready to be filled with beer. A Teflon tube descends from above, filling the cans with the desired beer. The number of cans filled at once depends on the size and capacity of the filling station, with more filler heads allowing for more cans to be filled at once. Most machines pour slightly more than the required amount into each can to account for spillage. GX Canning offers end-to-end capabilities to fill 12oz. standard, 12oz. sleek, 16oz. standard cans, and other sizes upon request.

Step 5: Adding the Ends

The top part of the can, the end or lid, is dispensed from above and clangs onto the open cans. Some setups may have a vacuum sealing machine that sprays nitrogen into the can as the lid is added, expelling any remaining oxygen.

Step 6: Seaming the Cans

A seamer fastens the end to the rest of the can. Each full can is lifted into the seamer for double seaming, which involves two rollers rotating around the can to crimp the end and can together. Some seamers may drop the end and seam simultaneously.

Step 7: Rinsing outside of the Cans

To prevent stickiness, the outside of the cans are rinsed to remove any spillage. The cans are then carried into a blow-off tunnel for a quick burst of air to remove any remaining water before they are dried.

Unleashing Your Beverage Empire What to Consider When Canning

Ready to take your beverage business to the next level and introduce your craft beer to the world? The canning process is a crucial aspect to consider, as even small variations in material and packaging can impact your product’s flavor, taste, and quality. Here’s a guide on what to expect and what to look for in a canning machine.

Start with Your Goals

To ensure the success of your venture, define your goals from the start. This is especially important in the beverage industry where standards need to be upheld from production to consumption. Outline your plan for distribution, the type of canned options you want to offer, and talk to experts in the field to gain insights.

Mind Your Space

Canning involves a lot of space, so make sure you have enough room for storage, organizing, and production. Consider the number of cans you’ll store, electricity requirements, necessary equipment, safety standards, and ease of loading/unloading. Plan ahead and allocate enough space to meet your production goals without creating headaches.

Budget Matters

Budgeting for canning can be unpredictable with changes in material costs, supply chains, and consumer preferences. Consider your options, whether to opt for a mobile vendor or contract canning or invest in your own equipment. If you’re just starting out, a mobile vendor may be the right choice, but for established brands, research the long-term implications of purchasing a canning machine. Don’t forget installation and maintenance costs, output speed, and the machine’s ability to keep up with your demand. Efficient machines may cost more upfront but can save time and labor costs in the long run.
