Beer Canning Equipment
Beer canning has seen a major resurgence in recent years among craft and microbreweries looking for an efficient way to package and distribute their products. This guide will explore all aspects of beer canning equipment needed to can beer, from an overview of the entire canning system to a breakdown of the individual components.
Overview of a Beer Canning Line
A complete beer canning line is comprised of several pieces of equipment that work together to clean, fill, seamer and package filled beer cans. Here is a high-level overview of the typical beer canning line process:
- Empty Cans – Cans arrive to the brewery empty on pallets via a can supplier. Cans move through the canning line on a conveyor system.
- Can Depalletizer – Takes layers of empty cans from pallets and places them onto the conveyor.
- Can Rinser – Cans are rinsed clean prior to filling. Usually a hot water spray system.
- Can Filler – Filled with beer to the proper level, often using vacuum and CO2 purge cycles.
- Seamer – Seals the lid onto the filled can using rollers that crimp the edge.
- Pasteurizer – Quickly heats filled cans to stabilize beer and kill bacteria.
- Labeller – Labels are wrapped around cans if required.
- Packaging – Six packs, cases, pallets for distribution.
Additionally, a canning line will also need all the standard brewery equipment like fermentation tanks, brite tanks for beer storage, filtration systems, cooling systems and more. Automation and control systems are also critical for monitoring throughput, efficiency, carbonation levels and other parameters.
Now let’s break down the major components of a canning line in more detail.
Beer Canning Equipment Guide
The following table provides an overview of the typical beer canning machinery:
| Equipment | Function |
|---|---|
| Can Depalletizer | Takes layers of empty cans from pallets and loads onto conveyor |
| Can Rinser | Cleans and rinses interior + exterior of cans |
| Can Filler | Fills cans with beer to correct level |
| Seamer | Seals lids onto filled cans |
| Pasteurizer | Stabilizes beer by quickly heating filled cans |
| Labeller | Applies labels to cans after filling |
Can Depalletizer
A can depalletizer, sometimes called a destacker, is used to transfer layers of empty cans from pallets provided by the canning supplier onto the conveyor of the canning line. This automation equipment uses vacuum plates to lift entire layers of cans, separating them from pallets as needed to feed the canning line. Models are sized based on the dimensions of pallets and cans being run.
Can Rinser
Since cans come directly from the manufacturer, a heated can rinse system is needed to wash both the interior and exterior of cans before filling. Most can rinsers use a hot water spray system to vigorously clean cans just prior to filling. Some use ionized air rinses too. This ensures no debris, oil or contaminants enter the cans during the filling process.
Can Filler
Can fillers handle the precise filling of each can with carbonated beer. Most systems use volumetric filling logic by measuring CO2 levels. Typically a two-step CO2 purge and vacuum process is used prior to bottom-up filling. No oxygen should touch beer to avoid oxidation. Fill levels are electronically monitored to ensure each can is filled equally for consistent packaging. Automated systems can fill at very high speeds.
Can Seamer
Also referred to as a seaming unit, the can seamer is critical for applying lids and sealing cans air tight through a process called double seam crimping. Two rotating wheels fold the lid over the rim of the can in multiple stages to create two sealed folds. This protects beer from oxygen and contamination. The seaming wheels must be precisely aligned to the can diameter, often with change parts, to create a hermetic seal.
Pasteurizer
While the canning process should be sanitary, beers are quickly pasteurized after packaging by heating filled cans to stabilize flavors and kill bacteria. Pasteurizers use a hot water spray or bath process for rapid heating. The pasteurization time and temperature depends on the beer recipe and packaging materials. This extends shelf life for distribution while minimizing beer taste impact.
Labeller
High speed label application systems can be integrated into canning lines if branding cans is desired. Pressure-sensitive label applicators quickly and accurately wrap labels around each can after filling and pasteurization. Labels serve to build brand recognition and inform consumers about the beer. Clear or opaque labels are options.
Beer Canning Line Capacity and Layout
Canning lines are typically categorized by the maximum number of cans that can be filled per minute, which also determines overall output. The following table provides some typical benchmarks:
| Canning Line Speed | Cans Per Minute | Cans Per Hour |
|---|---|---|
| Small | 30 cpm | 1,800 cph |
| Medium | 60-100 cpm | 3,600-6,000 cph |
| High Capacity | 150+ cpm | 9,000+ cph |
The physical footprint of a canning line varies based on configuration but they often have length around 100 feet to allow inline space for each process. Conveyors provide product travel through rinsers, fillers, sealers and pasteurizers in order. Height is another factor for ergonomic access and lift systems.
Given their complexity, custom-designed solutions are common to match equipment to production environment and output targets in the most compact, efficient floorplan. Modular systems provide flexibility as needs change. Consult an experienced canning line integrator for layout recommendations. Budget, production goals, beer types and packaging formats impact possible configurations.
Factors When Choosing a Beer Canning Line
Selecting filling and sealing equipment for a craft brewery project depends on weighing several factors against budget:
Speed – Desired hourly canning throughput based on demand. Scalable growth options.
Automation – Improves speed, efficiency and consistency. Sterile.
Size – Dimensions based on space. Height for lifts. Length of conveyors.
Output Volume – Total barrels packaged per year. Various can formats.
