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

DMX detector during operation

Principle of operation of the X-ray detector

The tested product is fed into the device chamber using the "C" belt conveyor at a constant speed. The X-ray radiation emitted by the "A" lamp is limited to a beam "B" with a width of several millimeters using the collimator - two parallel plates. The radiation beam passes through the tested product and is then directed to the "D" detector consisting of X-ray photodiodes that record the received radiation. The tested product absorbs a certain part of the radiation, therefore lower intensity radiation reaches the "D" detector. The degree of radiation absorption depends on the height of the product, its density and composition. Signals from the detector "D" are converted into a digital X-ray image by the industrial computer "E". The obtained X-ray image is checked for dark spots (higher density foreign bodies) and deviations (position, shape, etc.) from the reference image using special software and appropriate algorithms.

A pneumatic rejecter is used to separate defective products. Other systems for separating or marking defective product are available on request. The X-ray detector is equipped with numerous test programs to ensure its reliable operation. X-ray images of questionable products are saved in the detector's memory.
