What is an optical sorting system and how does Raytec Vision technology work?
An optical sorting system uses optical sensors (RGB, NIR, multispectral) to detect defects, impurities, or foreign objects in food products and automatically separate them. Raytec Vision designs these machines to ensure the highest standards of food safety and quality.
Which industries and products can benefit from Raytec Vision solutions?
- Fresh fruits and vegetables
- Processed and packaged products (e.g., frozen foods, canned goods, snacks)
- Agricultural products such as unwashed potatoes, where it is critical to remove soil, stones, and green material
What is the difference between optical sorting machines and X-ray inspection machines?
- Optical sorters use light (visible, near-infrared, multispectral) to detect color, shape, and surface defects.
- X-ray machines detect internal or dense contaminants, such as metal, glass, bones, fish bones, or hard plastics, that cannot be identified with optical inspection alone. Raytec Vision offers both technologies to meet different food safety needs.
How do I choose the right machine for my product/industry?
Some key selection criteria:
| Criterion | Importance |
|---|---|
| Type of product (shape, size, color, texture) | Determines choice of optical vs multispectral sensors |
| Type of contaminant/defect | Whether it’s foreign objects, internal defects, or just visual/esthetic flaws |
| Production capacity / tons per hour | Defines machine size, speed, and throughput |
| Food safety / regulatory requirements | Ensures compliance with local and international standards |
| Ease of maintenance and after-sales service | Minimizes downtime and ensures technical support availability |
What are the benefits of installing Raytec Vision machines?
- Improved product quality

What are the emerging technologies in optical sorting and food inspection?
Some key trends include:
Multispectral and hyperspectral sensors
Artificial Intelligence / Machine Learning for advanced defect recognition
IoT / Industry 4.0 integration for remote monitoring and data analysis
Greater sustainability: reduced energy consumption, less waste, and overall process efficiency
How are costs and initial investment managed?
Investment depends on the chosen technology, production capacity, and type of contaminant/defect to be removed.
Raytec Vision supports customers with ROI (Return on Investment) analysis, highlighting operational savings, waste reduction, and quality benefits.
Investments are often offset through reduced waste, lower manual quality control costs, and improved yield.
What are the space, energy, and infrastructure requirements to install a Raytec Vision machine?
Space: requires a dedicated area with proper access for loading/unloading, cleaning, and maintenance
Power supply: appropriate electrical requirements for power and stability
Environment: temperature, humidity, and cleanliness
Data connection: if remote monitoring or Industry 4.0 integration is required
How does Raytec Vision ensure compliance with international food safety standards?
- Machines are designed according to strict quality standards, using materials suitable for food environments
- Internal and external certifications and validations ensure compliance with local and global regulations
- Quality control and testing before shipment
