Case Study | X-ray Inspection for Ready-Meal Lunch Boxes with Meat and Bones

With the rapid growth of ready-meal and central kitchen production, food safety standards are becoming increasingly strict. One of the key challenges for manufacturers is how to accurately detect foreign bodies inside sealed lunch boxes — especially when the meals include meat with bones.

Recently, we provided an X-ray foreign body inspection solution for a food manufacturer producing ready-meal lunch boxes consisting of three dishes and rice, including bone-in meat.

Customer Challenges

During production, the customer faced several difficulties:

• Bone-in meat products often cause false alarms on metal detectors

• They needed to detect metal, glass, stone, hard bone fragments and other foreign bodies

• Inspection must be online and high-speed

• Products must be inspected after sealing — without opening or damaging the package

Therefore, the customer required a stable, reliable and highly accurate inspection solution that supports traceability.

Our Solution: Food-Grade X-ray Inspection System

Based on the product structure and production layout, we configured a food-grade X-ray inspection system for online detection of the lunch box products.

Key advantages include:

✔ Detects metal, glass, stone and dense bone fragments
✔ Not affected by aluminium foil or multilayer packaging
✔ Suitable for bone-in meat and complex meal structures
✔ High-precision image detection with stable performance
✔ Optional automatic rejection system
✔ Inspection data can be stored for traceability and quality records

During testing, the system clearly identified abnormal foreign bodies even when the meal contained bone-in meat, providing strong technical support for food safety control.

Results & Customer Feedback

After installation and commissioning, the customer reported:

• Higher detection efficiency

• Reduced product risk and complaints

• Improved internal quality control

• Enhanced brand trust and market competitiveness

The system is now running continuously and stably as part of the customer’s daily quality assurance program.
