In the modern food processing industry, ensuring food safety is the top priority for manufacturers. Metal contamination in food not only affects product quality but can also pose serious health risks to consumers and damage a company's reputation. As a result, food metal detectors have become essential equipment in production lines, safeguarding food safety. What is a Food Metal Detector? A food metal detector is a device that can detect metal contaminants in food. It operates based on electromagnetic induction principles, using high-frequency electromagnetic fields to identify metal contaminants such as iron, copper, and stainless steel, effectively preventing foreign objects from entering the market. Statistics show that thousands of food recall incidents occur worldwide each year due to foreign object contamination, with metal contamination accounting for a significant proportion. Consequently, an increasing number of food companies are adopting advanced metal detection equipment to reduce potential risks. How Does a Metal Detector Work? A metal detector typically consists of a conveyor belt, detection coils, a control system, and a rejection mechanism. As food passes through the detection area, the device generates a high-frequency magnetic field. If metal contaminants are present, the magnetic field changes, triggering an alarm, and the rejection system automatically removes the contaminated product to ensure food safety. Why Do Food Companies Need Metal Detectors? Protect Consumer Safety – Prevents metal contaminants from causing harm, such as dental injuries or digestive system damage. Enhance Product Quality – Effectively controls foreign object contamination in the production process, improving product quality and increasing consumer trust. Meet Industry Regulations – Ensures compliance with food safety standards such as HACCP, IFS, and BRC. Reduce Recall Risks – Food recalls can cause significant financial losses and reputational damage; metal detectors help identify problems early in the production process, minimizing recall risks. Which Food Industries Benefit from Metal Detectors? Food metal detectors are widely used in various food processing industries, including: Baked Goods (bread, biscuits, etc.) Meat and Seafood (frozen foods, processed meats, etc.) Dairy Products (cheese, milk powder, etc.) Snack Foods (nuts, candies, etc.) Grain and Oil Products (rice, flour, etc.) How to Choose the Right Metal Detector? When selecting a metal detector, consider the following factors: Detection Sensitivity – Can it detect tiny metal contaminants? Packaging Compatibility – Is it suitable for aluminum foil packaging? Operating Environment – Can it function effectively in high-humidity or high-temperature environments? Automatic Rejection System – Can it quickly remove non-compliant products? Conclusion Food safety is a matter of public health, and food metal detectors play an irreplaceable role as the “gatekeepers” of product quality, effectively reducing contamination risks. As the food industry continues to raise safety standards, metal detection technology is also evolving to provide more efficient and precise solutions for manufacturers.

Located in Sichuan, China, Chuanwei Food Co., Ltd. is a well-known manufacturer of Chinese-style cured sausages and other meat products. Since its establishment, the company has earned a strong reputation in both domestic and international markets for its high-quality products and strict quality control. Chuanwei Food is committed to blending traditional craftsmanship with modern technology to ensure that every sausage is safe, delicious, and free from foreign contaminants. Problem: Aluminum Clip Residues in Sausages During the sausage production process, minced meat is mixed with seasonings, stuffed into natural or synthetic casings, and sealed with aluminum clips. The sausages are then hung in curing rooms for up to two months to dry and ferment. In the slicing and packaging stage, workers manually remove the casings and aluminum clips. However, in some cases, small aluminum clip residues may remain attached to the sausage, posing a serious food safety risk. Previously, Chuanwei Food used standard metal detectors, but due to the high salt and moisture content of the sausages, strong product effects interfered with the accuracy of metal detection. To overcome this challenge, the company sought a more advanced inspection solution to ensure food safety and product quality. Ultimately, Chuanwei Food chose Shan'an Technology’s X-ray inspection system to precisely detect aluminum clip residues and other contaminants in sausages. Solution: X-ray Penetration Technology for Reliable Foreign Object Detection Due to the high water and salt content in meat products, traditional metal detectors often suffer from false alarms caused by product effects. This phenomenon makes it difficult to accurately identify foreign objects. To address this issue, Shan'an Technology’s X-ray inspection system was introduced. Unlike conventional metal detectors, X-ray machines use high-energy X-rays to penetrate products, allowing for the detection of a wide range of foreign objects, including: *Aluminum fragments *Stainless steel, iron, and non-ferrous metals *Glass, stones, and hard plastic contaminants Implementation at Chuanwei Food To ensure optimal performance, Chuanwei Food conducted rigorous testing at Shan'an Technology’s technical center.
