Beverage Canning Line
Modern Machinery supplies canning lines that handle carbonated cola, non-carbonated juice, and beer. The system uses isobaric filling for carbonated drinks and gravity filling for still drinks. The line supports can sizes from 150 ml to 500 ml and works with aluminum, tinplate, and PET cans.
What is a Beverage Canning Line
A beverage canning line is a production system that fills and seals drinks into metal or PET cans for retail distribution.
The filling method changes based on the product. For carbonated drinks (cola, soda, sparkling water), MD uses isobaric filling. This method keeps the gas in the liquid under pressure and stops foaming. The isobaric system handles carbonation levels up to 4.1 volumes of CO₂. For still drinks (juice, iced tea, flat water), MD uses gravity filling. This method uses a simple flow valve and works faster for low-viscosity liquids. For beer, we offer a vacuum filling option to reduce oxygen pickup.nnThe line supports can sizes from 150 ml to 500 ml and switches between aluminum, tinplate, and PET cans with quick-change parts.

Key machines in a CSD Canning Line
Automatic Can Depalletizer
This machine receives stacked pallets of empty cans. It removes the cans layer by layer and feeds them onto the conveyor line.
Can Rinsing Machine
The rinser flips each can upside down. Spray nozzles inject purified water or sterile air to wash out dust and loose particles before filling.
2-in-1 Can Filler u0026 Seamer
This monobloc integrates two functions. The filling turret fills the can with the set volume. The seaming turret applies the easy-open lid and forms the double seam.
Air Dryer
High-velocity air knives blow off residual water from the can exterior after the warmer and before the wrapper.
Can Warming Tunnel
This heated tunnel raises the can temperature to 25–35°C. Warming prevents condensation on the can surface when it moves into a warm packing area. The warmth also stabilizes internal pressure for carbonated products.
Combined Half-Tray Shrink Wrapper
This machine groups the cans into fixed packs (e.g., 4×6 or 6×4). It places a cardboard tray under the group. The film shrink unit wraps the group with PE film and applies heat to shrink the film tightly around the tray and cans.

Features of the 2-in-1 Filler-Seamer Monobloc
The isobaric system uses compressed CO₂ gas to equalize the pressure inside the can and the filler bowl. The drink flows in under the same pressure as the can. This method stops the release of dissolved CO₂, so the final product keeps its fizz without excess foam. The system handles carbonation up to 4.1 volumes.
For juice and flat water, MD uses a gravity feed valve. The liquid flows from the elevated bowl into the can by gravity alone. This design is simpler, uses fewer moving parts, and runs faster for non-carbonated products.
Each filling position has a proximity sensor. The sensor checks for a can before the valve opens. If a can is missing, the valve remains closed. This action prevents liquid spills and reduces product waste.
The seaming turret uses a first-operation roller and a second-operation roller. The rollers form the double seam step by step. The seamer checks the seam thickness and hook length during the cycle to guarantee a leak-proof seal.
Modern Machinery supplies change kits for different can diameters and heights. Operators swap the can grippers, starwheels, the filling valve stroke, and the seamer rollers. The complete change takes about 90 minutes, depending on the size difference and operator experience.
The conveyor and grippers support aluminum (soft metal), tinplate (harder metal), and PET (plastic). The machine adjusts gripper pressure to avoid denting aluminum or crushing PET.
The filling bowl, pipes, and valve manifolds have CIP connections. Operators run a hot water and caustic detergent cycle between product changes. This design cuts manual cleaning time.
The filler-seamer discharge starwheel matches speed with the warming tunnel infeed. The conveyor uses a frequency drive to adjust speed. This synchronization prevents cans from pushing against each other and avoids dented ends.
Project workflow from formula to installation
Product and Can Specification
Modern Machinery reviews your beverage recipe (CO₂ volume, viscosity, pH), can material (aluminum, tinplate, or PET), can dimensions, and lid type. We confirm the filling method: isobaric, gravity, or vacuum (for beer).
Factory Layout Drafting
Our CAD department drafts the plant layout. The drawing marks the 6 machine positions, conveyor lengths, service connections (compressed air, CO₂ gas, electrical, and drainage).
Assembly and Factory Acceptance Test (FAT)
We assemble the line in our factory. We invite you to run your actual cans and drink samples. During the FAT, we measure filling accuracy, seam integrity (cut and inspect the seam), and overall line speed.
Installation u0026 Training
Our field service team handles the mechanical setup and electrical connection at your location. We then start up the line, adjust the seamer rollers, train your operators, and provide the maintenance documentation.

Select Your Canning Line by Beverage Type, Size, and Output
By Beverage Type
- Carbonated Drinks (Cola, Tonic, Soda) – Use isobaric filling. This method preserves CO₂ volume and prevents foaming. Handles up to 4.1 volumes CO₂.
- Still Drinks (Juice, Iced Tea, Flat Water) – Use gravity filling. This method is faster and uses less energy for non-carbonated products.
- Beer – Use isobaric with a vacuum pre-evacuation option. This combination keeps carbonation and cuts dissolved oxygen.
By Can Size
- 150 ml – 250 ml – Mini cans for energy drinks, small juice portions, and sample sizes.
- 250 ml – 355 ml – Standard for cola, beer, and single-serve beverages.
- 355 ml – 500 ml – Tallboys for craft beer and larger juice servings.
By Hourly Output
- 1,000 – 3,000 CPH – For craft beverage producers and start-up brands.
- 4,000 – 8,000 CPH – For regional distributors and contract packers.
- 9,000 – 15,000 CPH – For large-scale beverage plants with multi-brand contracts
Frequently Asked questions
What is the difference between a 2-piece can and a 3-piece can? Does your line handle both?
A 2-piece can has a seamless body formed from a single sheet of aluminum through a drawing and ironing process. It is lighter and used for beer and carbonated soft drinks. A 3-piece can has a body made from a flat sheet rolled and welded into a cylinder, with two separate ends. It is typically made of tinplate and used for some juices, teas, and non-carbonated products. Modern Machinery’s canning line handles both types. The seamer adjusts to the different material thicknesses and end styles automatically.
What is the maximum carbonation level your isobaric filler can handle?
The isobaric filling system handles carbonation levels up to 4.1 volumes of CO₂. This covers standard lagers (2.5–2.7 volumes), most craft beers (2.7–3.2 volumes), and high-carbonation sodas and sparkling waters (3.5–4 volumes). For products above 4.1 volumes, we recommend a counter-pressure filler with additional foam control features.
Do I need a separate can warmer if I am not labeling my cans?
Not necessarily. The warming tunnel is primarily used to raise can temperature above the dew point to stop condensation. Condensation can wet cardboard trays, weaken shrink film seals, and cause corrosion on cans during storage. Even if you do not label, we recommend a warmer for any product filled cold (below 10°C) that will be packed in cardboard or shrink film. For ambient-temperature filling, you may bypass the warmer.
How does the seamer check seam quality during production?
The seamer includes a seam inspection system that monitors seam thickness and hook length during the sealing cycle. Some models use sensors to measure the seam dimensions in real time. If the seam falls outside the set tolerance, the machine alerts the operator or automatically rejects the faulty can. We also recommend manual seam cutting and inspection at regular intervals (every 30–60 minutes) as a standard quality practice.
What is the minimum can size and maximum can size your line supports?
The standard line supports can diameters from 50 mm to 85 mm and heights from 80 mm to 200 mm. This covers mini cans (150–200ml), standard 330ml and 355ml cans, and tall 500ml cans. For sizes outside this range, we offer custom engineering. Please provide your specific can dimensions for a confirmed fit.
