Our X-ray systems for packaged piece goods have been specifically designed for use in the food industry and are mostly deployed for end-of-line quality control purposes. They combine highly efficient contaminant detection with the greatest ease of operation and a hygienic design, and they comply with all key standards in the food industry. X-ray inspection systems not only detect metals, but also many other contaminants, such as glass, ceramics, stones, raw bones and PVC, not to mention a variety of product defects. All of this means precise end-of-line inspection and reliable protection against customer complaints and recalls.
X-rays screen the packaged piece goods transported on a conveyor belt. Our special analysis software uses the signals to create a digital X-ray image, which it examines for contaminants and many other product defects, such as air bubbles, too much or too little weight, and breakages. Integrated separation systems then ensure reliable removal. More information on how Sesotec X-ray inspection machines work is available here.
A flat conveyor belt moves the product being inspected evenly through the X-ray beam, which means it is possible to scan products in rows.
The X-rays are electrically generated in the X-ray tube. They leave the tube through a narrow slit and penetrate the product being inspected from bottom to top as a fan-shaped beam. Depending on the product’s height and density, some of the X-rays are absorbed by the product.
The linear detector line installed above the conveyor belt converts the radiation that reaches it into an electrical signal from which a digital image is created.
