Olive oil and edible oil lines are built around accurate dosing of a viscous product. Depending on the machine, the product and the container format, dosing may be volumetric or piston based, mass-flow or gravimetric, or weight based on load cells.
A typical oil line runs: depalletizer or container feed, rinser, filler, capping station, optional capsuler for premium glass, labeller and end-of-line packaging. Where oxidation matters, an inert-gas system may be fitted to manage headspace.
Technical Buying Guide — Used Oil Bottling Lines
Identify the dosing technology on the specific filler and ask for its calibration and maintenance records. Different principles behave differently with viscosity and temperature variation, so match the technology to the oils and container sizes you actually run rather than to a general rule.
Check product-contact materials, seals and gaskets for compatibility with your product, and confirm whether an inert-gas pre-flush or headspace system is present and operational on that machine.
Closures for oil include screw, pilfer-proof, T-cap and cork depending on the package. Confirm which closure tooling and container formats — from small glass bottles up to large PET containers — the supplied change parts cover.
Frequently asked questions
Which filling technology is used for olive oil?
Volumetric or piston, mass-flow or gravimetric, and weight-based filling are all used. The right choice depends on the product, the container format and how the specific machine is configured.
Why is inert gas used on oil lines?
Inert gas can be used to manage headspace and limit oxidation where the machine is equipped for it. Check whether that system is present and working on the specific line.
What should I verify before buying?
Dosing technology and calibration records, product-contact materials and seals, viscosity and product compatibility, inert-gas system if fitted, closure tooling and the container formats covered by the included change parts.
