Dongguan, August 25, 2026 — Doria (Dongguan Doria Intelligent Technology Co., Ltd.), a leading global manufacturer of industrial inspection equipment, today officially launched its 2026 new generation smart metal detector series. Equipped with the innovative Multi-Frequency Synchronous Detection (MFSD) technology and intelligent adaptive anti-interference algorithms, the new series delivers comprehensive breakthroughs in detection sensitivity, anti-interference capability, and production line compatibility, providing an elevated metal contaminant inspection solution for food, pharmaceutical, chemical, plastics, and other industrial production lines.
Traditional single-frequency metal detectors often face the dilemma of reduced sensitivity and increased false alarm rates when dealing with inspection scenarios characterized by strong "product effects," such as high-moisture, high-salt, or metal-foil packaged products. Doria's 2026 new generation metal detectors overcome this challenge through innovative multi-frequency synchronous detection technology, simultaneously emitting five groups of detection signals at different frequencies (50kHz–1000kHz), combined with phase analysis algorithms to accurately distinguish genuine metal contaminants from the conductive signals of the product itself.
Field test data shows that in complex application scenarios such as wet meat products, pickled foods, and aluminum-foil packaging, the new generation product achieves up to 25% higher spherical metal detection sensitivity compared to traditional single-frequency equipment, while reducing false rejection rates by over 40%, effectively minimizing production line material waste and downtime.
| Parameter | Technical Specification |
|---|---|
| Detection Sensitivity (Air) | Ferrous Fe ≥ Φ0.5mm / Non-Ferrous ≥ Φ0.8mm / Stainless Steel SUS ≥ Φ1.0mm |
| Detection Frequency | Multi-frequency synchronous 50kHz–1000kHz (5 frequencies operating simultaneously) |
| Conveyor Speed | 20–60 m/min (stepless adjustment, customizable) |
| Detection Aperture | Width 100–600mm × Height 50–300mm (customizable) |
| Protection Rating | IP65 (standard) / IP66 / IP67 (optional for high-pressure washdown environments) |
| Construction Material | SUS304 stainless steel (SUS316L food-grade optional) |
| Rejection Method | Push-arm / Air-blast / Flap / Lifting type (optional) |
| Power Supply | AC 220V / 50Hz (110V optional), Power ≤ 200W |
| Data Interface | RS485 / Ethernet / USB, MES/ERP system integration ready, Industry 4.0 compatible |
| Product Memory | Stores up to 100 product parameter presets, one-click switching |
| Alarm Method | Audio-visual alarm + automatic rejection + line stop (optional) |
1. Smart Product Effect Compensation
Built-in AI learning algorithm automatically learns the signal characteristics of the inspected product and dynamically adjusts detection parameters. For challenging products such as freshly thawed, partially frozen, or high-salt items, optimal detection status is maintained without repeated manual calibration.
2. Self-Diagnostics & Predictive Maintenance
The system continuously monitors equipment operating status, including coil temperature, power stability, and conveyor belt tension. When potential failure risks are detected, maintenance reminders are issued in advance to avoid unplanned downtime and ensure continuous production line operation.
3. Complete Data Traceability & Compliance Support
Automatically records every inspection event (timestamp, product type, alarm reason, rejection status), with data exportable in CSV/PDF format, meeting audit traceability requirements of international food safety standards including HACCP, BRC, IFS, and FDA.
4. 7-inch Color Touchscreen HMI
Industrial-grade color touchscreen with intuitive user-friendly interface, supporting multi-language switching (Chinese/English/Spanish/Russian, etc.), enabling operators to get started quickly without specialized training.
| Industry Sector | Typical Applications | Detection Focus |
|---|---|---|
| Food Processing | Meat products, bakery, confectionery, dairy, snacks, frozen foods | Iron filings, wire, metal fragments from equipment wear |
| Pharmaceutical | Tablets, capsules, powders, APIs, medical devices | GMP compliance, ultra-high sensitivity metal particle detection |
| Plastics & Chemicals | Plastic pellets, rubber products, chemical raw materials, films | Protect downstream processing equipment, prevent mold damage from metal |
| Textile & Apparel | Garments, home textiles, non-woven fabrics, toys | Broken needles, iron filings and other sharp metal foreign object detection |
| Wood & Building Materials | Engineered wood, furniture, panel processing | Nails, screws and other embedded metal detection |
✓ Superior Cost Performance: Core components independently developed, prices 30%–50% lower than imported brands, with performance indicators reaching international equivalent levels.
✓ Fast Delivery & Customization: Standard models delivered in 7–15 days, supporting full customization of detection aperture, rejection method, conveyor belt material, etc., to meet special production line requirements.
✓ Global Service Network: Products exported to over 50 countries and regions across Southeast Asia, Middle East, Europe, and South America, providing remote technical support and on-site installation & commissioning services.
✓ Strict Quality Assurance: CE, FCC, RoHS certified, 2-year whole-machine warranty, 3-year core component warranty, lifetime technical support and spare parts supply.
As global food safety regulations become increasingly stringent and consumer demands for product quality continue to rise, metal inspection equipment has become an indispensable quality assurance component in modern industrial production lines. According to industry research data, the global industrial metal inspection equipment market size is expected to exceed USD 2.5 billion in 2026, with a CAGR of 6.8%, with the Asia-Pacific region experiencing the most rapid growth.
Doria Intelligent Technology remains committed to driving industrial inspection upgrades through innovative technology. The launch of the new generation smart metal detector not only further enriches the company's product portfolio but also marks an important step forward for domestic brands in the high-end industrial inspection sector. Moving forward, Doria will continue to invest in R&D, achieving continuous breakthroughs in AI intelligent inspection, X-ray foreign object detection, and integrated checkweighing & sorting solutions, providing superior industrial inspection solutions for customers worldwide.
