Candy itself typically won't go off in a metal detector, as metal detectors are designed to detect metallic contaminants, not food products. However, there are certain factors that could cause a candy product to trigger a metal detector under specific circumstances. Here's an explanation of how and why this might happen:
1. Presence of Metal Contaminants
Metal detectors are designed to detect foreign metal objects, such as:
- Steel (e.g., from machinery)
- Iron (e.g., from tools or equipment)
- Aluminum (e.g., from packaging materials)
- Stainless steel (e.g., from processing equipment)
If a piece of candy is contaminated with a metal fragment, whether it’s from equipment, packaging, or other sources, the metal detector will be triggered. For instance, if a candy piece contains a small metal fragment or if there’s metal in the packaging (such as a foil wrapper), the detector will identify this and trigger an alert for the contaminant.
2. High-Density Ingredients or Fillers
Certain high-density ingredients, such as those found in some candies (e.g., nuts, caramels, or hard candies), can sometimes cause issues with detection. If the candy is densely packed or has a thick coating, the metal detector might have difficulty distinguishing between the food and small metal contaminants. However, this does not mean the candy itself will "go off" or be falsely detected as metal—rather, it's the presence of metallic contamination that would trigger the alert.
3. Packaging
The type of packaging can also affect metal detection. Candy wrappers made of metallic materials (e.g., aluminum foil or metallic laminates) can cause issues in the detection process, especially if the candy is not fully wrapped or if the packaging contains metallic parts (like staples or foil). Metal detectors will often detect this type of packaging, but it's not the candy itself causing the reaction—it's the metallic packaging.
4. Type of Metal Detector
Different types of metal detectors have varying levels of sensitivity. Some may be more sensitive to smaller metallic contaminants, even those embedded in thicker or denser food items like candy. Metal detectors with multi-frequency detection and higher resolution may be more effective at detecting small or fine metal particles embedded in the candy or packaging.
5. Techik’s Metal Detectors for Candy
Techik’s metal detectors, like those in the MD-Pro series, are designed to detect a variety of metal contaminants within food products, including candies. These detectors are equipped with high sensitivity and advanced algorithms that help distinguish between food and metallic objects. Techik's systems can detect contaminants as small as 1mm (or even smaller, depending on the specific product) without falsely triggering on the candy itself.
Techik detectors also feature automatic rejection systems, ensuring that any contaminated candy is immediately removed from the production line, improving safety and quality control.
Conclusion:
Candy itself will not go off in a metal detector unless it contains metallic contaminants or metallic packaging. Metal detectors are highly effective at identifying and rejecting metal contaminants that may accidentally get mixed with the candy during manufacturing, handling, or packaging. If the candy is properly processed and does not contain metal objects, it should pass through the detector without issue. However, metallic packaging or contamination from production equipment could cause a metal detector to trigger.
