Remember the X-ray Intelligent Foreign Object Defect Detection System that provides a clear view of hidden contaminants within products? Today, we introduce one of its cutting-edge variants:

The "Dual-Energy Model"

In challenging scenarios of food quality inspection, such as detecting residual bones in nuggets or small stones in fries, traditional single-energy X-ray systems often struggle due to similar densities between bones and meat, leading to inaccuracies. Additionally, overlapping fries with varying thicknesses can present varying gray levels, making it difficult to detect foreign objects effectively.

So, what's the solution?

Introducing the "Dual-Energy X-ray Intelligent Defect Detection System," which excels in revealing foreign objects in complex scenarios.

Both involve X-ray inspection, but the outcomes are strikingly different. Is it magic?

Dual-energy high-definition detection uncovers hidden foreign objects with precision. Just as a prism splits sunlight into a rainbow, an X-ray beam can be "split" into low-energy and high-energy rays. When these rays pass through an object, they experience different energy attenuations, especially if the object contains varying materials, creating a distinct "code" for each material's dual-energy signals. Standard X-ray equipment only performs single-energy detection, failing to capture these nuanced differences.

Equipped with a 0.1mm dual-energy high-definition detector, the system captures both high and low-energy X-rays after they pass through the object, converting these "codes" into two distinct images. Coupled with a dual-energy image analysis algorithm, it goes beyond simple gray level differences to detect foreign objects, comprehensively analyzing both gray level variations and material attributes. This addresses the challenge of detecting tiny foreign objects in complex, overlapping products.

· Clear differentiation of materials

The high and low-energy X-ray images each focus on different details of the object.

↑In the detection of raw chicken breast meat for chicken steaks and nuggets, calcified bones strongly attenuate low-energy X-rays, making bones prominent in the low-energy image. High-energy X-rays, on the other hand, easily penetrate thick meat, solving the occlusion issue caused by thick meat layers.

· Material identification

Based on the difference in attenuation coefficients between high and low-energy X-rays, the atomic number of different materials can be calculated, revealing the composition of the substance. An atomic number diagram is created, clearly distinguishing food from foreign objects.

↑The atomic number diagram simplifies the complex background into a uniform color, ensuring that foreign objects, no matter how small (down to 1mm), are clearly visible.

Equipped with Hikvision Guanlan Large Model: Enhanced Detection Accuracy

The dual-energy X-ray intelligent defect detection system integrates AI algorithms for automatic identification and precise image judgment. Leveraging the Hikvision Guanlan Large Model, pre-trained on vast samples from diverse scenarios, it rapidly transfers learned knowledge to new production environments, accelerating project deployment and application.

For meat products like chicken, beef, and pork, as well as processed foods such as fries, nuggets, and popcorn chicken, and frozen vegetables like edamame and cauliflower, the large model significantly improves detection accuracy for tiny foreign objects. It achieves a 10% increase in the comprehensive detection rate and reduces the false positive rate from 20% for ordinary models to less than 1%.

Hardware Design Upgrade: Reliable and Efficient Operation

Safety starts with attention to detail. Tailored to the high standards of meat production, the dual-energy model features an anti-stick conveyor belt, multiple anti-condensation technologies for intelligent dehumidification and moisture resistance, and an integrated exterior design for ease of cleaning and safety.

Channel numbers can be customized based on needs, such as simultaneous detection of two products, combined with a conveyor belt anti-deviation design, doubling production capacity. Efficient air ducts rapidly cool the cabinet, extending the X-ray tube's lifespan and ensuring stable production with extended standby times.

Data Integration with Production: Ensuring Quality Traceability

Quality inspection results, operating conditions, and records are meticulously recorded and can be integrated with enterprise production management systems like ERP, MES, and WMS.

When an increase in foreign objects is detected over a period, targeted improvements can be made to the production process. Should a quality issue arise with a specific product, the corresponding production batch can be identified for quality traceability.

In today's society, food safety remains paramount. Hikvision's dual-energy X-ray intelligent defect detection system offers reliable detection of metals, stones, glass, bones, and rubber fragments. Coupled with an automatic rejection system, it ensures efficient quality inspection on the production line, suitable for various scenarios including meat processing, packaged foods, frozen vegetables, and pet food quality inspection. Furthermore, the dual-energy model, integrated into an overall solution, can analyze meat fat content, scientifically control nutrition, and enhance product health quality.
