A food metal detector machine is a specialized device that uses electromagnetic induction technology to identify metal impurities in food products during the packaging stage. Our high-precision FL500C series food metal detector machine detects all types of metal contaminants, including ferrous (iron, steel), non-ferrous (copper, aluminum), and stainless steel particles. Whether you run a small bakery or a large-scale food processing plant, this metal detector for food industry delivers consistent performance to keep your operations compliant with HACCP, GMP, and FDA standards.

How Does A Food Metal Detector Work?
Our metal detector for food packaging is engineered to work with various packaged food forms—from bags of snacks and boxes of frozen meals to bottles of sauces and cans of preserved foods. The machine uses advanced digital signal processing to identify metal impurities. When products pass through the detection channel, the system generates an electromagnetic field. If metal is present, it disrupts the field, triggering an immediate alert through audio and visual signals, and can automatically reject contaminated items via customized mechanisms. This process ensures continuous, reliable monitoring without slowing down your line.



Key Features of Metal Detectors for Food Industry

Smart Data Management: Integrated logs capture up to 700 detection events, with statistical tools to simplify reporting and support food safety compliance.
Automatic Diagnostics: The metal detector machine with automatic diagnostics runs at power-on to prevent and ensure consistent performance.
Customization Options: We offer size customization, rejection mechanisms, and housing options for wet, dusty, or high-vibration settings.


Benefits of Using A Metal Detector in Food Packaging
Enhanced Productivity: Fast parameter recall and automated rejection systems keep your line moving with fewer interruptions.
Improved Safety: Early detection of metal contaminants reduces the risk of recalls and helps protect your brand’s reputation.
Regulatory Compliance: Built-in recording and reporting functions help meet HACCP, GMP, and other industry standards with accuracy.
Seamless Integration: Customizable input and rejection systems ensure the metal detector machine fits seamlessly into your existing food packaging workflows.
FAQ:
Q1. What is the sensitivity range for different metals?
Sensitivity varies by model—for example, it can detect ferrous metals as small as 1.0mm. Actual performance depends on product characteristics, but we provide tailored solutions
Q2. Can the machine be customized for specific production lines?
Yes! We offer adjustable speeds, sizes, and automated systems to fit your line perfectly.
Q3. What certifications does the food metal detector have?
Our equipment is CE certified, the factory is ISO9001 certified, and the belt is FDA approved for food safety.
Q4. How does the self-learning function work?
You just run your product through the detector once according to the program; it automatically learns and saves settings for future use.
