Food-Grade X-Ray Testing Equipment (FA-XIS Series) with Metal Detection & Rejection

The Food-Grade Metal Detector Automatic X-Ray Inspection System (FA-XIS Series), developed by Tianjin ENAK Automation Equipment Co., Ltd., is a professional B-end Testing equipment designed for food safety inspection. It integrates advanced X-ray technology and high-precision metal detection, providing comprehensive contaminant screening for food production enterprises to meet global food safety standards.

Product Overview

This Testing equipment covers five models (FA-XIS3012 to FA-XIS8030) to adapt to different production line scales, from small-batch precision food processing to large-volume bulk production. It is suitable for both packed and unpacked foods, detecting contaminants in plastic, glass, metal, and foil packaging without being affected by food moisture, salt content, or temperature.

Product Performance

Equipped with VJT X-ray generators and DT sensors, the system ensures stable radiation output and high-quality imaging. It supports 100 product inspection parameter memories, enabling quick switching between different food types. With an IP66 protection rating and SUS304 stainless steel construction, it resists corrosion and high-pressure cleaning, fitting harsh food production environments.

High-Sensitivity Metal Detection for Food-Grade Applications

As a core Testing equipment for food safety, the FA-XIS Series delivers industry-leading detection sensitivity tailored to food-grade requirements. It can identify ultra-small metal contaminants—including 0.3mm SUS304 stainless steel balls and 0.2×2mm metal wires—impurities that pose hidden risks in food production (e.g., metal shavings from mixer wear in bakery lines or fragment residues in meat processing). This level of sensitivity ensures compliance with strict regulations like FDA and EU 178/2002, preventing contaminated products from reaching consumers. Unlike traditional metal detectors, it maintains accuracy across all packaging types (foil, metalized film, glass jars) and food textures (wet, frozen, high-salt), with false alarm rates below 0.05% to avoid disrupting high-speed production.

Automatic Rejection Device to Block Defective Products

The integrated automatic rejection system of this Testing equipment acts as a non-negotiable barrier against defective products. With multiple rejector options (flipper, pusher, air jet, etc.), it adapts to diverse food types: air jets for fragile items like glass-bottled sauces, heavy-duty pushers for canned goods, and flippers for lightweight snacks. Triggered in 0.3 seconds upon detecting contaminants, it outperforms manual sorting—critical for lines running at 70m/min (FA-XIS3012/4016). For example, in a frozen vegetable line using FA-XIS5025, the system removes 100% of batches with 1.5mm glass fragments, eliminating recall risks that could cost enterprises millions. The rejectors are made of food-grade SUS304, with smooth surfaces that prevent product residue buildup and secondary contamination.

Automatic Data Recording for Traceability & Quality Management

This Testing equipment supports end-to-end data traceability, a cornerstone of modern food quality management. It automatically logs inspection data (timestamp, product batch, contaminant type, operator ID) and stores up to 100 product profiles for quick recall. Data can be retrieved via USB or synchronized to ERP/MES systems via Ethernet, enabling real-time quality monitoring. In case of a safety incident, enterprises can trace affected batches in minutes—e.g., if a retailer reports metal contamination in a cereal pack, the FA-XIS Series’ logs pinpoint the exact production shift and line, narrowing recalls to specific batches instead of entire inventories. The data also empowers proactive quality control: analyzing trends (e.g., frequent wire detection in a snack line) helps identify and fix root causes like worn conveyor parts, reducing contamination risks long-term.

Food-Grade Material Selection & Precision Fabrication

Every component of the Testing equipment adheres to food safety standards. The frame and tunnel use SUS304 stainless steel, which resists corrosion from acidic/alkaline cleaning agents and meets FDA food contact requirements. The stainless steel undergoes 3-stage polishing (grinding, buffing, mirror finishing) to achieve Ra≤0.4μm surface roughness—preventing food particle adhesion and enabling easy sanitization. The anti-static polyurethane belt is non-toxic, wear-resistant, and compliant with EU 10/2011 food contact regulations, ensuring no harmful leaching even at 80℃. Critical parts like conveyor rollers are machined via CNC turning, with dimensional tolerance within ±0.05mm, ensuring stable belt operation and avoiding vibration-induced detection errors.

Core Component Integration & Calibration

The Testing equipment’s performance relies on premium global components: VJT X-ray generators (US) for stable radiation output, DT sensors (Finland) for high-resolution imaging, and Schneider electrical parts (France) for reliable power control. During assembly, technicians follow ISO 9001 protocols—each wire connection is torque-tightened and labeled, and the X-ray module is sealed with IP66-rated gaskets to prevent dust/water ingress. Post-assembly, a 120-hour calibration process ensures accuracy: engineers test 50+ food samples (frozen, wet, powdered) across all models, adjusting X-ray voltage/current to optimize contrast. For FA-XIS8030 (800×300mm tunnel), calibration focuses on uniform radiation distribution to detect 0.3mm SUS304 fragments even at the tunnel edges, guaranteeing no blind spots.

Hygienic & Ergonomic Structural Design

Hygiene and usability are embedded in the Testing equipment’s design. The IP66 rating allows high-pressure washing (100bar) of the tunnel—essential for dairy or meat plants where daily sanitization is mandatory. The conveyor belt features a tool-free quick-release design, enabling full disassembly in 5 minutes for deep cleaning. Ergonomically, the 17-inch touchscreen is angled at 15° for optimal visibility, with height adjustable from 700-950mm to suit operators of different statures. Control buttons are backlit and color-coded (green for start, red for emergency stop), reducing operation errors. The modular rejector system allows on-site replacement in 30 minutes, minimizing downtime—critical for 24/7 production lines.

Q1: Can the FA-XIS Series Testing equipment detect non-metallic contaminants like stones or glass in all food types?

A1: Yes. The series detects 1.0-1.5mm glass/ceramic balls and stones across most foods. For low-density products (e.g., bread, crisps), the high-contrast X-ray imaging clearly distinguishes 1.0mm contaminants; for high-density products (e.g., canned meat), the 350-480W X-ray power (FA-XIS6030/8030) ensures penetration while maintaining sensitivity. Note: It cannot detect low-density non-metals (nylon, hair) due to similar density to food—we offer optional optical modules for such needs.

Q2: How do I choose the right model (e.g., FA-XIS4016 vs. FA-XIS6030) for my production line?

A2: Select based on 3 factors: 1) Product size: FA-XIS4016 (400×160mm tunnel) for small items (snack packs), FA-XIS6030 (600×300mm) for large products (5kg flour bags). 2) Line speed: FA-XIS3012/4016 (10-70m/min) for high-speed lines (confectionery), FA-XIS5025-8030 (10-40m/min) for bulk products (frozen vegetables). 3) Load capacity: FA-XIS8030 (50kg) for heavy items (canned tuna), FA-XIS3012 (5kg) for lightweight goods (yogurt cups). Our team can also conduct on-site line assessments to recommend the best model.

Q3: Does the Testing equipment comply with global radiation safety standards?

A3: Absolutely. It meets EN 61010-02-091 (EU), CFR 21 Part 1020 (US), and GB 18871 (China) radiation standards. The surface radiation dose rate is <0.5μSv/h—far below the 2.5μSv/h global safety limit. Safety features include: 1) Interlock system: X-ray shuts down if the tunnel cover is opened. 2) Emergency stop button: Cuts power to all components in 0.1 seconds. 3) Radiation warning lights: Alert operators to active X-ray use. We also provide radiation safety training and annual compliance testing.

Q4: Can the Testing equipment’s data be integrated with our existing ERP system?

A4: Yes. The system supports Ethernet and RS232 communication, enabling seamless integration with SAP, Oracle, or custom ERP/MES systems. Our technical team provides API documentation and on-site support to set up data synchronization—inspection results (pass/fail, contaminant type) are automatically sent to your ERP in real time. This eliminates manual data entry, reduces errors, and streamlines quality audits (e.g., providing historical data to FDA inspectors in minutes).
