In the food production industry, metal contamination is one of the most common and dangerous issues that can occur. Metals such as iron, stainless steel, aluminum, and copper can be introduced at various stages of processing due to the use of machinery, handling equipment, and utensils. A high-sensitive conveyor belt type metal detector is essential in ensuring the safety and quality of food products by detecting any metallic contaminants during processing or packaging.
As part of a HACCP (Hazard Analysis and Critical Control Points) program, these detectors help meet food safety standards, retailer guidelines, and legal requirements. The system ensures that contaminated products are identified and removed before reaching consumers.
### Types of Contaminants
There are three main types of metallic contaminants that a food metal detector can detect:
- **Ferrous** – Magnetic and conductive, easily detected.
- **Non-Ferrous** – Non-magnetic but conductive, relatively easy to detect.
- **Stainless Steel** – Most challenging due to low conductivity and non-magnetic properties. Sensitivity may decrease if the product is wet or has high salt content.
For non-metallic contaminants like glass, ceramics, or stones, an X-ray inspection system is recommended for enhanced detection.
### Key Features
