Canned food production uses compressed air for filling, seaming, retorting and packaging, with air contacting the product and the container. The system must be hygienic and oil-free to protect food safety.
Key applications
- Filling and dosing systems
- Seaming and lid handling
- Retort and sterilisation controls
- Labelling and palletising
Air quality
Specify ISO 8573-1 Class 0 oil-free air for contact applications, with drying to prevent moisture issues. Control air needs a low dew point for reliable operation of filling and seaming machines.
System design
Use oil-free compression with drying and filtration, design for washdown, and provide redundancy for continuous canning lines. Point-of-use filtration protects the filler and seamer.
