Working principle 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.

The X-ray detection system detects metal contaminants, bone pieces, glass, ceramics, stones and high-density plastics. Product defects are also detected, such as cracks or crumbling of the product, too high or too low filling level of the packaging, or empty spaces. At the same time, the device 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.

Why choose our X-ray metal detectors?

The DMX X-ray detector is a device that not only detects metals, but also pieces of bones, glass, ceramics, stones as well as some types of plastics, e.g. PVC and rubber. The detector also detects product defects, such as deficiencies, damage or deformations. Thanks to this, the consumer will receive a final product of the highest quality. Due to its compact design, it can be easily installed even in an existing production line, where it can be the last control - CCP (Critical Control Point). The detector is characterized by a hygienic design - stainless steel construction, adapted for use in the food industry. The device has been designed for easy and quick cleaning and disinfection. The design protects the operator against X-ray radiation. This ensures time savings and comprehensive safe operation, without the need for mandatory documentation of working times.

Software with automatic learning function ensures simple and intuitive operation. The device automatically sets appropriate algorithms and filters to quickly introduce a new product. This function facilitates working conditions and saves the operator's time, who no longer needs to have specialized knowledge and training. The software allows you to control different products (max. 20) from different production lines. The detector recognizes which product passes through the X-ray beam in any order and independently selects the appropriate set of parameters. This allows for savings related to the purchase of only one detector instead of several and the lack of the need for prior sorting and changing product batches in the control unit. An additional benefit is the detection zone analyzer, which allows you to define zones in the X-ray image for which you can separately count and weigh the product. The obtained sensitivities are consistent with the guidelines in food directives and are even better than those required by IFS. The device is equipped with a complete log that allows you to identify settings and events, which provides solid arguments during internal and external audits. The detector can be operated on-site or remotely, ensuring short downtime in the event of technical problems.
