Metal Detection & Weighing for Bakery & Snack Lines
Protect biscuit, chip and nut packs from metal contaminants—and control giveaway at 200+ packs/min.
Sensitive MD heads. Precision checkweighers. No product crushed.
Industry Challenges
Risks Unique to Dry Foods
· Wire & tool fragments: Mixer blades, sieve wires slip into dough/nut lines.
· Invisible profit leak: ±2g over-fill on snack packs costs ~3% material yearly.
· Dust-coated sensors: Flour/sugar demand sealed MD coils.
· Speed-pressure: 200+ ppm leaves zero manual inspection window
Our Solution
Optimized Metal Detection + Checkweighing
We size high-sensitivity metal detectors and dynamic checkweighers for bakery/snack:
Metal Detector NG-706: Phase-tune cancels product effect; detects Fe 0.6mm / SS 1.5mm in biscuits & nuts.
Checkweigher NG-709: ±0.2g accuracy at 200 ppm; auto-feedback to filler.
Soft reject integration: Air-knife or light-flap removes contaminated pack without breakage.
Data link: MD reject log + CW batch report via USB/Ethernet for HACCP.
