Foreign Material Detection
X-Ray Food Inspection Systems
As X-rays pass through the product, they image density differences: stone, glass and metal — even inside the package or the product itself — are detected and automatically rejected. Where the metal detector stops, X-ray begins.
How It Works
It Sees Density,
Not Color
- Pass: The product travels on a conveyor beneath the X-ray curtain.
- Imaging: The detector measures how much the beam is attenuated as it passes through the product.
- Analysis: Software flags anomalies in the density map.
- Rejection: The reject system (pusher arm, air jet, or drop flap) removes the defective product from the line.
- Logging: Every detection is automatically archived with its image.
Detection Capability
What Does It Detect?
Metal
Including stainless steel — even inside aluminum foil packaging.
Glass
Glass fragments a metal detector can never see.
Stone and ceramic
Recognized by density, even when it is the same color as the product.
Plastics with metal-like density
High-density plastics such as PVC and Teflon.
Choosing the Right Point
Bulk Product or Packaged Product?
In-Line — Bulk Product
Foreign material is removed before it is ever packaged; only the defective section is rejected, keeping product loss to a minimum.
- Nuts, pulses, and IQF flows
- Machine protection upstream of crushers and mills
- Low product loss, high tonnage
End-of-Line — Packaged Product
The final critical control point: it sees inside sealed packaging and verifies every package on its way to your customer.
- Metal + foreign material in foil packaging
- Deep-learning in-line inspection
- Image-backed reject archive and traceability
Our X-Ray Model
VALOR 5 — X-Ray Hazelnut Sorter
Our real X-ray model on the nut side is VALOR 5; it sees inside without cracking the shell and separates empty and defective kernels with X-ray plus AI. Beyond hazelnuts, it also works for pistachios, walnuts and almonds.
