| Key control | Fill accuracy, closure integrity, CIP time |
The product fixes the filling principle; output only fixes the size. Still liquid at a steady density runs gravity or volumetric; carbonated product needs isobaric; thick product with solids needs a piston; product sold by weight runs a load cell. A machine picked ahead of the product usually gets picked again.
Thin walls may lead to deformation or collapse under pressure, compromising the efficiency of the filling line.
Four variables sit behind a fill number: the dosing principle, the product temperature, the bottle geometry, and the condition of the valve or piston seal. A machine that holds its tolerance on the factory test can drift in the plant when the product arrives warmer or the bottle wall gets thinner.
| Principle | Doses by | Fails when |
|---|---|---|
| Gravity | Fill level in the bottle | Bottle geometry varies |
| Volumetric | Chamber volume | Valve seal wears |
| Isobaric | Volume under counter-pressure | Pressure or temperature drifts |
| Piston | Displacement | Product carries solids |
| Load cell | Net weight | Product temperature moves |
The unit behind this configuration is the Gravity Filling Machine for Still Water.
The parts cost is small; the time is not. A format change touches star wheels, guide rails, grippers, the cap chute and the recipe. On a line with two formats and two changes a day, the annual hours lost exceed the price of a second small machine in many plants.
Site requirements, air and water consumption sit with the Volumetric Filling Machine for Still Water.
The neck finish sets the rinser clamp, the filling valve seal and the capping head. A change of a millimetre in the thread is a change of change parts and often of the capper. It is the single most under-specified item in a filling line enquiry.
The same question is worked through from another angle in Troubleshooting Common Filling Machine Problems: Leaks, Foam, Inaccuracy.
Gravity fills to a level set by a tube, so accuracy depends on the bottle. A volumetric filler measures a chamber volume, which keeps it accurate when the format changes. Gravity is simpler and cheaper; volumetric is more repeatable when the bottle changes.
It depends on the principle and the product. A volumetric or load cell filler holds a tighter band than gravity on a variable bottle. The tolerance belongs in the acceptance protocol, measured by weight on a defined sample.
From tens of minutes to over an hour, set by the circuit volume and the soil. It is a fixed cost per production day and should be planned as downtime, not squeezed into the shift.
Valve seals, piston seals, capping head inserts, guide rail blocks and one set of change parts for the second format. These are the items that stop a line for days when they fail.
