Selection Guide (Choose the Right Conveyor System Fast)
Share your product + line details and we’ll recommend the best conveyor tunnel configuration.
Step-by-step inputs (for accurate configuration)
- Product + packaging: material, size, and product effect
- Line speed: packs/min and belt speed
- Tunnel opening: belt width & product height (with clearance)
- Environment: dry vs washdown, IP requirement
- Reject method: pusher / air blast / drop flap / diverter
- Validation: test routine and logging needs
Conveyor Selection (Quick Checklist)
| Key Item | Best Practice | Notes |
|---|---|---|
| Opening / Tunnel Size | Match product width & height with safe clearance | Smaller opening generally improves sensitivity |
| Reject Method | Choose by pack type & line speed | Reject confirmation affects uptime and verification |
| Product Effect | Plan sensitivity using real product samples | Wet/salty products can increase false rejects |
Tip for sensitivity planning
Sensitivity depends on tunnel size and product effect. Share your target test piece requirement and product details—we’ll estimate a realistic achievable range and recommend the right configuration.

Validation & Documentation (Audit-Friendly Workflow)
Many food sites run routine tests and documented corrective actions. We support your validation planning with practical guidance.
Routine performance tests
Define test frequency and certified test pieces. Confirm reject function and record results per SOP.
- Start-up / shift / changeover checks
- Test piece pass/fail criteria
- Reject verification guidance
False reject reduction
Wet/salty products may increase product effect. Configuration and stable installation help reduce downtime.
- Learn-mode optimization
- Tunnel sizing guidance
- Mechanical stability checklist
Records & traceability (optional)
Where required, event logs and access controls can support traceability and accountability workflows.
- Event logging options
- Access control options
- Audit-ready documentation package
Note: Final compliance depends on your configuration and local regulations. This page provides general guidance for planning.

FAQ
Answers for procurement and engineering teams.
What contaminants can a food metal detector detect?
Food metal detectors typically detect ferrous, non-ferrous, and stainless steel.
Achievable sensitivity depends on tunnel size, product effect, packaging, and installation.
How do I choose the right conveyor metal detector?
Key inputs are product size and packaging, tunnel (aperture) size, line speed, target sensitivity and reject method.
For wet/salty products, configuration and stable installation help reduce false rejects.
Will wet or salty products reduce sensitivity?
Yes. Conductive products can create product effect. Proper configuration, stable mechanical installation,
and optimized learn modes reduce false rejects while maintaining detection performance.
How do we validate performance for HACCP or customer audits?
Typical validation includes documented test routines using certified test pieces, reject verification checks,
and clear SOPs for start-up/changeover/corrective action. Optional records can support audit workflows where required.
What information do you need to quote the right model?
Product type + package size, tunnel size (belt width & product height), line speed, target sensitivity,
reject method preference, and washdown/IP requirements.
