Cocoa Products Foreign Body Detection Solution — X-ray Machine Application Case

Ensuring food safety starts at the source. Cocoa beans, as the core raw material for chocolate and other cocoa-based products, are highly susceptible to foreign body contamination during harvesting, drying, transport, and storage. Common contaminants include stones, metal fragments, glass, and ceramics—posing a significant risk for manufacturers and exporters.

Client Background

Our client, based in West Africa, is a major exporter of cocoa beans with an annual processing volume exceeding 2,000 tons. Their main markets include Europe and South America, where food safety regulations are especially strict. Although they had previously relied on manual sorting and magnetic separation, they struggled to eliminate non-metallic foreign bodies such as small stones and glass fragments.

Solution

To address this challenge, we recommended our SA-X Series X-ray Inspection Machine, designed to detect a wide range of dense foreign objects in bulk cocoa beans. The system is equipped with a high-resolution X-ray generator and advanced imaging software, capable of detecting:

• Metal fragments (iron, aluminum, stainless steel, etc.)

• Stones

• Glass pieces

• Ceramic particles

• Hard plastic debris

To match the client’s bulk material handling process, we customized the machine with a sealed protective housing and automatic rejection system, ensuring efficient inline inspection without interrupting the production flow.

Client Feedback

After installation and testing, the client reported a significant improvement in detection accuracy, especially for hard-to-identify non-metallic contaminants. The rejection system reliably removed defective batches, reducing product complaints and minimizing risk during third-party inspections.

“The X-ray system gives us greater confidence in our quality control. It has helped us pass stringent export inspections more easily, especially for the EU market.”

Application Benefits

• Wide detection capability: Detects both metallic and non-metallic dense contaminants

• Non-contact inspection: No damage or contamination to cocoa beans

• Flexible for raw materials: Suitable for both bulk and packaged cocoa

• Improved compliance: Helps meet international food safety standards
