XSpectra®: a disruptive technology

We at Xnext® have developed XSpectra®, a new generation of X-ray inspection systems, which can analyse the composition of a product directly on the production line and determine its compatibility/incompatibility with the quality requirements.

XSpectra® is the result of over 8 years of R&D and almost €8 million investment.
Fully developed and engineered in-house, the technology is protected by 2 patents.

In short, XSpectra®

  • A unique technological solution for the identification of both high-and low-density foreign bodies.
  • Real time non-destructive quality tests on industrial production lines, guaranteeing very high-quality standards (target zero defect).
  • Increases the efficiency of production processes and their sustainability thanks to its abilities to characterise products quickly and accurately.

How does XSpectra® work?

The general structure and functioning of X-ray inspection systems

X-ray inspection machines are commonly placed in a specific spot on the production line, so that they can eject non-compliant products. An X-ray beam produced by a so-called X-ray tube passes through the product as it moves along the conveyor belt and is then projected on an X-ray detector. Measurement of the differences in X-ray beam absorption between the product and a foreign body is the basis of X-ray inspection.

The ground-breaking identification performance of XSpectra®

Whereas conventional X-ray machines use detectors based on scintillators, XSpectra® exploits semiconductor detectors. Scintillators only give indirect evaluation of the number of X-ray photons, independently from their energy.
To date, there is nothing on the market such as XSpectra®, as current inspection systems are capable to perform a 1- or 2-level of energy analysis. XSpectra®, instead, is capable of distinguishing multispectral energies, meaning that it can detect the full energy spectrum of the incident radiation, up to 1024 energy levels.

XSpectra® offers a completely new approach of quality inspection, resulting from a unique combination of 3 different high-level innovations: photonics, nuclear electronics and Artificial Intelligence Algorithms.

Photonics

The XSpectra® EYE

A solid state CdTe detector that converts photons of the electromagnetic radiation into directly proportional electric signals.

Nuclear electronics

The XSpectra® BRAIN

An integrated circuit (ASIC), for the data acquisition and management, for the specific technical features of XSpectra®.

Machine learning artificial intelligence

The XSpectra® SYNAPSE

Neural machine learning algorithms that allow it to identify patterns, models, recurrent schemes within the dataset.

XSPECTRA®: A PROCESSING SYSTEM EASY-TO-USE, EASY-TO-LEARN, EASY-TO-PERFORM

The inspection machines that adopt XSpectra® on the production line become smart! The integration of XSpectra® within the production process allows for the implementation of a KPI management system which, by enabling remote control, means fast and effective corrective interventions. This also speeds up the whole control process, thus streamlining the entire production activity, while guaranteeing high quality standards.

Besides, thanks to the specific properties of XSpectra®, the quality control machines become flexible, meaning compatible with different productions on the same line, without requiring set-up interventions. Today, technicians must intervene by setting new configuration parameters, which often cause delays and malfunctions.

Why do we make the difference?

Comparing existing inspection technologies

PRO

CONS

XSPECTRA

METAL DETECTOR

PRO

Low-cost, efficient in detecting metal foreign bodies, both magnetic and not

CONS

Fail to detect metals when the product is enclosed in a metal container; not always effective in identifying steel, as the carbon composition influences the metal resistivity

XSPECTRA

No influence from the material composition of the package

INFRARED & UV

PRO

Very high accuracy on physical-chemical properties of sample inspected

CONS

Can identify contaminants located only within the superficial layers, due to the low penetration ability provided by the electromagnetic radiation energy

XSPECTRA

Detect the contaminant no matter its position in the product

X-RAY SINGLE OR DUAL ENERGY

PRO

Thanks to the higher radiation energy, can penetrate deeply into materials detecting defects even if placed in a metal or glass container

CONS

Not sensitive to low density FBs; density analysis (no chemical, but only physical properties)

XSPECTRA

Detect both low- and high-density FBs; chemical and physical characterisation of the product

CONVENTIONAL X-RAY SYSTEMS VS. XSPECTRA®

The chart shows the energy spectrum range generally used by X-ray inspection systems to identify foreign bodies within the foodstuff

XSPECTRA

• operates on a wider energy range
• puts strong emphasis on lower energies
• detects both low – & high-density FB
• is not affected by the type of containers

In short, XSpectra®: the must-have solution for in-line real time inspection

THE SOLUTION IS XSPECTRA®, A WIN-WIN-WIN KEY FOR THE SOCIETY, INDUSTRIES AND THE ENVIRONMENT

Thanks to its unique properties, such as the capacity to characterise the chemical-physical components of the inspected materials, XSpectra® can be used in many sectors: food, waste and material recycling, pharmaceutics, metallurgy, plastics and composites, electronics, clothing, shoes, biomedical, extraction industry, and security controls.

Specific Advantages

Higher safety levels

XSpectra® detects both high- and low-density foreign bodies, whereas the conventional X-ray systems detect only high-density foreign bodies.

Product nature recognition

Like no other technology currently available, XSpectra® performs an analysis of the physical and chemical properties of the product. It is like getting the fingerprint of the material inspected.

False positive alarms reduction

XSpectra® eliminates only non-compliant products, drastically reducing the number of FPA and consequently the risk and impact of product recalls

Detection speed

XSpectra® is faster than current technologies, thus increasing the number of products analysed on the production lines.

Toward smart factory

Very easy to use, XSpectra® supports the plant management with real-time information on the nature and the localisation of the problems identified

Multiple applications

Food, material recycling, pharmaceutics, metallurgy, plastics and composites, electronics, clothing, biomedical, extraction industry, security controls etc.

A WINNING BET: keep the products safe and the industry effective, while ensuring optimal sustainability!
