Quality Food Metal Detector & Food Grade Metal Detector manufacturer

As food safety regulations tighten and audits become more frequent, food manufacturers must be fully prepared to pass inspections and meet all compliance standards. One key factor in passing audits with ease is ensuring that your metal detectors, X-ray inspection systems, and checkweighers are fully documented and operational. To help food factories stay audit-ready, we’ve compiled a comprehensive checklist of the essential documentation you’ll need to provide during customer audits: 1. Metal Detector Documentation Daily Sensitivity Test Logs: Ensure your metal detectors are calibrated regularly, with daily tests verifying their effectiveness for detecting Fe, SUS, and Non-Fe metals. Test Piece Verification: Records showing that metal detectors have been tested with various test pieces. Reject System Function Log: Evidence that the reject system is working properly to remove contaminated products from the production line. Calibration Certificates: Certificates confirming that your machines are properly calibrated to meet industry standards. HACCP Validation: Documentation that your metal detectors are validated as Critical Control Points (CCPs) within your Hazard Analysis and Critical Control Points (HACCP) plan. 2. X-ray Inspection Documentation Image Verification Records: Logs that demonstrate the system’s ability to detect contaminants through image analysis. Product Learn Documentation: Details showing the products the X-ray system is calibrated to inspect. Reject Confirmation Log: Verification that rejected products are consistently logged for traceability. Detection Capability Report: A report detailing the effectiveness of the X-ray machine in detecting foreign materials. Annual Calibration Certificates: Certification that the X-ray system is calibrated yearly. 3. Checkweigher Documentation Accuracy Verification Logs: Records proving that the checkweigher’s accuracy is regularly tested. Zero / Span Check Records: Confirmation that the machine’s zero point and span range are checked frequently. Reject Records for Over/Underweight Products: Evidence that products that fail weight specifications are rejected. Packaging Weight Standards: Details showing that product weight standards are maintained for packaging. Maintenance & Calibration Logs: Maintenance records to prove that equipment is regularly serviced and calibrated. 4. General Audit Essentials Cleaning SOPs & Records: Documentation of cleaning procedures and frequency. Traceability Records: Systems that allow tracking of products from raw materials to the final product. Non-conformity Handling: Records of how deviations are detected, documented, and corrected. Preventive Maintenance Logs: Documentation showing proactive maintenance to minimize downtime. Operator Training Records: Proof that personnel are trained on using equipment and understanding safety standards.

In recent years, consumers have become increasingly concerned about food safety, especially in natural and minimally processed products such as fruits and dried fruits. Manufacturers are therefore seeking more advanced inspection technologies to ensure product purity, enhance production efficiency, and comply with international export standards.   Challenges with Metal Detection Traditional metal detectors are widely used in the food industry, but they have clear limitations when applied to fruits and dried fruits. Moisture and mineral interference: Fresh and dried fruits often contain natural moisture, sugar, and minerals that create product effects, reducing metal detection sensitivity. Limited detection range: Metal detectors can only identify metallic contaminants (Fe, Non-Fe, SUS) and cannot detect non-metallic foreign objects such as glass, stones, or hard plastic. Packaging restrictions: Many dried fruits use metalized film or aluminum foil packaging, which interferes with metal detection.   Benefits of X-ray Inspection X-ray inspection systems overcome these challenges and provide a comprehensive solution for fruit and dried fruit processing lines. They can detect a wide range of foreign bodies regardless of moisture or packaging material. Key advantages include: Detects both metallic and non-metallic foreign objects such as glass, stones, bones, and hard plastic. Stable and consistent performance in detecting loose, sticky, or irregularly shaped fruits. Applicable for both bulk inspection and packaged products. High-resolution imaging ensures accurate rejection of contaminated items.   Ensuring Consistent Quality and Compliance By integrating X-ray inspection, manufacturers can significantly reduce product recalls and customer complaints, while meeting international standards such as HACCP, ISO22000, and BRC. This technology helps ensure that every batch leaving the factory is safe, clean, and of consistent quality.   About Shan’an Technology With over 15 years of experience, Guangdong Shan’an Technology Co., Ltd. specializes in providing intelligent inspection and weighing solutions for the food industry.
