How to Set Up an Aluminum Can Filling Line for Beer

Views: 3069 Author: Howie SUN Publish Time:
A can line is rated in cans per hour because the seamer sets the pace, and the seam, not the filler, is where the rating is usually lost.
Key facts at a glance
Filling principleIsobaric for beer and CSD, volumetric for juice and tea
CapacityUp to 25,000 CPH
Can rangeStandard 250, 330 and 500 ml
SeamingRoller seamer integrated with the filler
OptionsHot fill for juice and tea, nitrogen dosing
Key controlFill level, seam tightness, dissolved oxygen

Why is can filling measured in CPH and not BPH?

A can line is counted in cans per hour because the container is the unit the seamer closes. CPH and BPH cannot be converted without the fill volume, and the downstream packer is sized in cases per hour. Comparing a 24,000 CPH can line with a 24,000 BPH bottle line compares two different plants.

What changes between a beer can and a juice can?

Beer and CSD run isobaric, cold, under counter-pressure. Juice and tea often run hot fill or a volumetric fill with a downstream pasteuriser. The can is the same format; the filler, the valve set and the temperature control are not, so one can line rarely covers both without a second specification.

What does a hot-fill can line need that a cold line does not?

A heated product path, a fill temperature control loop and a cooling tunnel after seaming. The can itself tolerates the heat; the lining and the product do not always. The temperature window belongs to the product specification.

What is the smallest viable can line?

Small can lines exist for craft producers, usually with a compact filler-seamer and manual or semi-automatic packing. The limit is not the filler but the seam quality control, which needs a tear-down station and a trained operator at any volume.

The same question is worked through from another angle in How Aluminum Can Filling Machines Handle Hot Juice.

How to read the numbers. Capacity figures are the reference ranges on the product specification. Seamer stops, can-size changeover and downstream accumulation sit outside a rated CPH, so plan on 0.65-0.85.

Frequently asked questions

How often is a seam checked?

At a fixed interval during production, by tear-down and measurement, plus a check after every seamer adjustment. The interval is set by the plant quality plan; the point is that it is measured, not inspected by eye.

Does a can line need nitrogen dosing?

It is common for beer, juice and some CSD, where headspace oxygen has to be pushed down. It is an option with a consumable cost, so it belongs in the utility and consumable schedule, not in the base price.

Why do cans dent on the conveyor?

Usually conveyor pressure or a jam at a transfer, not the can quality. Air conveyor pressure, guide rail gaps and accumulation length are the three settings to check first.

Can a can line run 330 ml and 500 ml in one shift?

With change parts for the filler, the seamer and the conveyor, yes. The changeover is longer than a label change and is normally scheduled between campaigns.

Key takeaways
  1. Dissolved oxygen in the finished can is the number that decides shelf life.
  2. Beer and juice cans share a format, not a filling specification.
  3. The seamer transfer is the most alignment-sensitive point on a can line.
  4. Seam quality needs a tear-down station at any volume.
