Kenwei Metal Detector Procedure for the Food Industry

Kenwei Metal Detector Procedure for the Food Industry

Kenwei offers a practical and reliable metal detector procedure designed for food manufacturers who demand safety, consistency, and compliance. As an experienced manufacturer of metal detectors and multi-head weighers, Kenwei combines proven inspection steps with easy-to-follow routines to protect product quality and meet regulatory requirements.

1. Pre-operation checks

Before production, inspect the detector and conveyor for cleanliness and damage. Verify power, grounding, and signal connections. Confirm the reject mechanism is functional and empty test samples are available. Quick pre-checks reduce downtime and false rejects.

2. Calibration and sensitivity verification

Calibrate the metal detector per product type using certified test pieces (ferrous, non-ferrous, and stainless). Record sensitivity settings and ensure they meet customer specifications and HACCP or internal food safety plans. Recalibrate after any major maintenance or product changes.

3. Product setup and challenge testing

Run challenge tests at production speed with representative packaging. Adjust detection thresholds so real contaminants are consistently caught while minimizing false trips. When paired with Kenwei multi-head weighers and packaging lines, set synchronized speeds and checkpoints for seamless operation.

4. In-line monitoring and routine checks

Implement scheduled verification during shifts: test blocks at defined intervals, log results, and act immediately on rejects. Use simple logs or digital records to track detector performance and trace incidents.

5. Maintenance and training

Perform regular cleaning, component inspections, and firmware updates. Provide operator training on basic troubleshooting, rejection handling, and record keeping. Kenwei supports on-site commissioning and technical training to ensure consistent practice.

6. Documentation and compliance

Maintain test results, calibration records, and maintenance logs to meet audit requirements and demonstrate due diligence. Integrating Kenwei metal detectors with automated weighing and packaging systems strengthens traceability and audit readiness.
