X-ray inspection systems for bulk goods

Our RAYCON BULK series X-ray inspection systems are used to inspect bulk goods such as coffee, tea and spices, and detect both metallic and non-metallic contaminants. They represent the state of the art in terms of guaranteeing contaminant-free food.

The complete systems consisting of vibration chute, X-ray scanner and reject system can be integrated straight away into any production line. They are user-friendly and comply with all key standards in the food industry. In optimal fashion, the inspected bulk goods make their way separately onto the conveyor belt by way of a vibration chute. After inspection, contaminants are removed from the product flow with pinpoint accuracy through reject flaps. This set-up provides reliable protection against customer complaints paired with minimal loss of material.

The benefits in detail

  • Our X-ray systems detect contaminants from 0.6 mm in particle size
  • They feature an outstanding design: hygienic, very quickly accessed and possible to service without tools
  • They provide hassle-free installation thanks to a modular design
  • Their space requirements are minimal thanks to a compact design and low center of gravity
  • They comply with common food industry standards, such as BRC, IFS and HACCP
  • They provide excellent radiation protection in line with the German X-ray Regulation (Röntgenverordnung − RöV)
  • Due to their low radiation energy levels for detecting contaminants in food, they can even be used with organic products in accordance with Directive 1999/2/EC
  • They detect contaminants such as metals, glass, ceramics, stones, raw bones, PVC, Teflon, rubber and glass-fiber-reinforced plastics in food
  • They detect metal contaminants from non-magnetic stainless steels and non-ferrous metals
  • The intuitive user interface provides the user with a swift overview and is extremely easy to operate
  • Thanks to the real-time operating system with flash card…
    • …our X-ray systems remove contaminants with precision, even when faced with high throughput levels
    • …their full processing power is used exclusively for product inspection
    • secure data storage is ensured, regardless of external influences
    • …you have full control of all hardware components for each system state
    • no UPS is needed to safeguard the system
  • The AuditCheck function actively assists the operator in process monitoring, thereby reducing the effort for manual logging on the line

Application examples



Vibration chute

Bulk goods are transferred evenly and continuously onto the conveyor belt by way of a vibration chute.


Conveyor belt

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.


X-ray tube

The X-rays are electrically generated in the X-ray tube. They leave the tube through a narrow slit and penetrate the bulk goods 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.


Detector unit

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.


Industry PC

This is where the X-ray image is analyzed for contaminants and other product defects.


Reject system

Detected contaminants are precisely removed through segmented reject systems with minimal loss of material. Different versions are available.
