X-ray Beam Orientation in Food Inspection: Maximizing Detection Performance

1/26/2021 Mekitec

Understanding X-ray Beam Orientation in Food Inspection

Selecting the right X-ray beam orientation for food products is crucial. There are three primary types of X-ray systems:

  1. Vertical beam systems
  2. Horizontal beam systems
  3. Combined beam systems

A good rule of thumb is to choose the inspection method based on your product's shape:

  • If your product is taller than wider, image it from the side
  • For products that are wide and low in height, use top-down inspection

Vertical Beam Systems: When and Why to Use Them

Standard X-ray inspection systems are typically designed for flat packages like:

  • Flow wraps
  • Pouches
  • Small bags

Vertical beam systems offer several advantages:

Top-Down vs. Down-Top Configurations

  • Top-down: X-ray generator placed above the products
  • Down-top: X-ray generator placed below the products

Benefits of top-down systems include:

  • Smaller generator size
  • Reduced X-ray power requirements
  • Prolonged generator lifetime
  • Lower operating costs
  • Compact system design

Horizontal Beam Systems: Ideal for Tall Packages

Horizontal (side-shoot) X-ray systems are best for products that are:

  • Taller than wide
  • Packaged in containers like:
    • Cans
    • Bottles
    • Tall cartons

Challenges with Tall Packaging

Tall food products present unique inspection challenges:

  • Foreign objects often settle at the bottom
  • Package quality defects appear in upper sections
  • High production line speeds
  • Minimal gaps between packages

Single vs. Multi-Beam X-ray Systems

Addressing Inspection Limitations

Challenges with single-beam systems:

  • Potential blind spots
  • Difficulty detecting contaminants in glass packaging
  • Limited visibility across different product sections

Multi-beam advantages:

  • Reduced blind spots
  • Improved detection from multiple angles
  • Better suited for complex packaging
