Metal Detectors

Metal Detectors Overview

Food metal detectors are critical inline inspection systems that identify ferrous, non-ferrous, and stainless steel contaminants in products, protecting consumers, brands, and production lines from recalls—mandatory for HACCP, BRCGS, and UK Food Standards compliance.

Conveyor/tunnel models suit packed foods like ready meals or meat trays, while gravity fall or throat detectors handle bulk powders/granules before packaging, often with auto-reject arms, flaps, or pushers and multi-frequency tech to cut false rejects in wet/frozen goods.

Common Examples

Type Application Key Features
Conveyor/Tunnel Packed meat, poultry, bakery (e.g., LOMA IQ3+) IP69K washdown, 3-400 ppm sensitivity, integrates with checkweighers 
Gravity Fall/Throat Snacks, spices, powders (e.g., LOMA Free Fall) 2-50kg/hr free-fall, auto-divert for rework, VFFS integration 
Pipeline Sauces, liquids, slurries (e.g., LOMA PS range) Non-invasive heads, pump sync, detects in conductive products
