Small foreign bodies and packaging defects are frequently not detected by food producers, but our inspection systems help reduce the risk of spoilage and food poisoning. The systems use low energy X-ray to produce highly detailed images of food products and damaged goods and can be used to check seals in food wrappers, locate packaging defects and find foreign particles of (almost) any size in (almost) any kind of food.
- Optimal detection capability
- Packaged or unpackaged products
- Single or multiple lanes
- Designed according to EHEDG guidelines
- Low false reject
- High probability of detection
Standard X-ray systems used for food inspection, especially for contaminants detection, are very much similar in terms of the fundamental technical basis for the acquisition of the X-ray images, 0.4 or 0.8 mm pixels, and Gadox (a robust, cheap and well-known material for X-ray imaging), to convert X-ray information to a digital number. The InnospeXion systems use low energy X-rays to produce highly detailed images of food products. The technology has received multiple awards, based on the very unique performance, with 50% higher contrast and typically 16 times better resolution. It can verify the integrity of seals in food wrappers, locate packaging defects and find foreign particles of (almost) any size in (almost) any kind of food.
High performance and fast image analysis software enables the automatic on-line detection and rejection of even the smallest and most difficult to detect foreign objects.
Examples are: small glass fragments in glass jars, bones in fish and chicken, small stones in bread and dried products, high-density plastics and rubber, and many others.
The InnospeXion low energy X-ray technology finds the smallest bones, due to a much higher contrast between bones and meat and lower X-ray energy, due to a 16X better resolution, and an advanced software solution. It offers the same speed as conventional systems, is hygienically designed, with a straightforward human interface. The system for fish and chicken bone detection is identical and installed worldwide in the fish & poultry industry. The InnospeXion low energy technology offers:
- reducing loss and making best use of raw materials
- better product classification and a better product price
- avoiding customer complaints
- a robust, reliable, and safe inspection technology
- hygienic design guidelines
For chicken and poultry, the Probability Of Detection (POD) for bones is less than 2 x 2 x 2 mm in continuously produced chicken fillets. substantially better than conventional systems. For fish, the minimum bone diameter is 0.2 mm, with a minimum length of 5 mm. The technology works on fillets, pieces, packaged products, ready meals, and others.
EXAMPLES OF USAGE
Detection of contaminants in large cheese blocks
High sensitivity and high resolution. Detection of sub-millimeter contaminants in large and thick cheese blocks cannot be accomplished using standard X-ray technology.
The InnospeXion solution offers: Detection down to 0.2 mm, Tailoring to the production line, EHEDG guidelines conformity, proven technology, dedicated software solutions e.g. for cheese internal structure quantification and validation.
Modern food production is a well controlled process. However, occasionally deviations occur, and contamination of the cheese with plastics, rubber, steel and other materials is possible.
Traditional X-ray imaging may find application to detect larger foreign objects of high density, but present day requirement is a detection of defects down to 0.2 mm and detection also of light foreign objects, such as some plastics and rubber, as well as integrity assessment of the packaging.
The InnospeXion technology is a hygienically designed system for the on-line inspection of food products, with a dual focus: verifying the conformity of the product in the package (if any), and detection of foreign objects.
Glass splinters constitute a major problem in the production of food products packaged in glass jars, bottles, and containers. The splinters may have very hazardous consequences. X-ray technology has been used for years for the inspection of filled glass packaging with food products. The problem is, that the normal X-ray technology is inadequate for the revelation of critical glass splinters. This is due to the fact that the contrast between the glass pieces and the product inside the glass jar has to be relatively large in order for automated image analysis algorithms to detect and correctly reject a faulty product. In addition, the resolution of the image acquisition sensor has to be high in order for as many pixels as possible to represent a defect. Unfortunately, high resolution and high contrast are in contradiction. High resolution implies small pixels, and hence a small “count number” due to a very small detection area. This makes noise be relatively high compared to a (small) “count” difference between a defect and a neighbor area without a defect.
The high contrast, high-resolution imaging in the Royal Awarded InnospeXion glass-in-glass detection system integrated with a novel, fast and very robust and reliable automatic glass splinter detection algorithm. This enables even the tiniest glass fragments to be detected, even when placed next to the glass wall.
This new X-ray technology pushes the detection level to the real need – to detect what is critical for the consumer.
