Target: Weight control and metal detection

For wet environments, at 100 ppm, with 5 conveyor belts


The Challenge

Target: Weight control and metal detection

A dairy producer required a solution to guarantee both accurate weight control and metal contaminant detection for tubs of spread cheese. The system needed to meet strict EU regulatory standards for packaged food while operating reliably in a wet production environment.

Key requirements included:

  • Dual inspection – Metal detection and weight control in a single system.

  • High throughput – At least 100 pieces per minute.

  • Precision – Weighing accuracy with a scale interval of 1 g.

  • Safe rejection – Reliable and hygienic removal of non-compliant products.


The Solutions

To achieve these goals, a combination checkweigher and metal detector system was provided, incorporating five conveyor belts for smooth product flow.

Key features included:

  • Metal detection – Containers pass through a detector antenna capable of identifying ferrous, non-ferrous, and stainless-steel contaminants, even in wet or conductive products. Contaminated items are automatically rejected into a dedicated collection bin for safe disposal.

  • High-accuracy weighing – Conforming containers are then weighed with 1 g accuracy. Products outside the set tolerance range (180–230 g in this case) are rejected into a separate bin, with cheese reclaimed for reprocessing.

  • Smart rejection controls – Photocells confirm each ejection, ensuring that non-compliant products are always correctly removed. Full-bin photocells alert operators when reject bins need to be emptied.

  • Throughput – The line operates at speeds of 100+ containers per minute, maintaining high production efficiency.


The Benefits

  • Space-saving design – Combines weight control and metal detection in a single compact system.

  • Operational reliability – Smart sensors provide real-time confirmation of rejection and system status.

  • Efficiency – High-speed throughput maintains production pace without compromise.

  • Comprehensive inspection – Guarantees 100% of products are both weight-compliant and contaminant-free.

  • High hygiene standards – Built for wet environments, supporting full wash-down and sanitation.
