Metal detection

Metal detection is a crucial link in food safety. It identifies metal particles that accidentally end up in your product — through machine wear, raw materials or human handling — and removes them before they reach the consumer. As a distributor of CEIA, the world's largest manufacturer of metal detectors, VME supplies high-precision detection systems and the expertise to integrate them seamlessly into your production line.

A metal detector works on the balanced coil principle: a transmitter coil generates an electromagnetic field, and two receiver coils are perfectly balanced. When a metal particle passes through, it disrupts that balance and generates a signal. The system thus detects magnetic (iron), non-magnetic (copper, aluminium) and stainless steel contaminants, and automatically ejects the affected product or triggers an alarm. CEIA goes further with unique multi-spectrum technology: multiple frequencies simultaneously, for maximum sensitivity with minimal false rejects.

• Food safety: metal contaminants are detected and removed before they reach the consumer
• Standards compliance: essential control point (CCP) for HACCP, IFS, BRC and GMP
• Consumer and brand protection: prevents recalls and reputational damage
• Maximum sensitivity: detection of iron, non-ferrous metals and stainless steel
• Fewer false rejects: multi-spectrum technology distinguishes product from metal
• Machine protection: prevents damage and downtime further down the line

Metal detection can be applied at any point on the line and for any product type. On the conveyor for packaged and unpackaged products, ready meals and fresh or frozen goods; in free fall for powders and granules (for example before a vertical bagging machine); and in pipelines for pumpable, liquid or viscous products such as cheese, sauces, soup and meat. This protects production lines in the meat, dairy, bakery, ready-meal and snack industries. Built in AISI 316L stainless steel, EU/FDA compliant and resistant to intensive cleaning.

As a distributor of CEIA, VME offers the complete THS range. Conveyor systems (THS/21) with a choice of ejection mechanisms, free-fall detectors (THS/G21) for powders and granules, pipeline systems for pumpable products, and the multi-spectrum THS/MS21 for the most difficult applications with strong product effect. All systems feature auto-learn, self-calibration and continuous self-diagnosis. We tune each system precisely to your product, line speed and hygiene requirements.
