X-ray detector (DMX)

X-ray detector (DMX)

The DMX type X-ray detector is designed to detect foreign bodies in food products with the highest sensitivity. The X-ray detector detects metal contaminants, bone pieces, glass, ceramics, stones and high-density plastics. The detector also detects product shortages or defects, such as cracks or crumbling of the product, too much or too little filling level of the packaging, or empty spaces. At the same time, the detector can mask signals coming from the type of packaging, e.g. metal clips. The product can be tested loose or in any type of packaging.

The X-ray detector is reliable, easy to use and designed for continuous operation. It is characterized by the highest sensitivity of foreign body detection and hygienic design. The X-ray detector meets the requirements of food quality management systems ISO 9001, ISO 22000, HACCP, BRC, IFS.

X-ray detector during operation



The detectors we manufacture are high quality products. They are distinguished in the market by:

  • Highest sensitivity for the detection of metals and foreign bodies in food products,
  • Ability to detect product deficiencies and defects - damage, breakage, etc,
  • Automatic adjustment of sensitivity and product learning,
  • Simple operation via touchscreen display with intuitive menu,
  • Manufactured from food-grade materials (FDA approved),
  • Long service life of key components - X-ray tubes and diodes.



RAYCON X-ray detectors are mainly used in the food industry and other industries with similar quality requirements - product liability, ISO 9000, TQM, machine and consumer protection. The detector makes it possible, without interrupting production, to check packaged products for the presence of foreign bodies which, due to their density, chemical composition or dimensions, absorb the emitted X-rays better or worse than the surrounding product.

On this basis, metals, glass, ceramics, stones as well as certain types of plastic such as PVC and rubber are detected in products. Product deficiencies or defects such as cracked or crumbled products, over- or underfilled packaging or trapped air can also be detected. At the same time, signals from the type of packaging can be masked, e.g. metal clips on the ends of sausages. The product can be tested in bulk or in any packaging - cardboard box, metallised film, plastic or aluminium tray, etc.



The controlled product, via a conveyor belt, is fed into the digital X-ray detector chamber at a constant speed. X-rays are emitted by a tube and, by means of a so-called collimator (two parallel plates), limited to a width of a few millimetres. The beam passes through the product under examination and is then directed to a digital detector consisting of X-ray photodiodes, which record the received radiation.

The product under test absorbs some of the radiation, so less radiation reaches the metal detector. The degree of radiation absorption depends on the height of the product, its density and composition. The signals from the detector are processed by an industrial computer and assembled into a digital X-ray image. Using special software and appropriate algorithms, the resulting image is checked for dark spots (foreign bodies with higher density) and so-called deviations (position, shape, etc.) from the reference image.

A pneumatic ejector is used to separate defective products. Other systems for separating or marking defective product are available on request. The machine is equipped with numerous test and evaluation programmes to achieve reliable operation and the ability to identify product defects. X-ray images of objectionable products are stored in the unit's memory.
