Detectable Composite Material for Wear-Resistant Food Processing

The patent applies composite materials by incorporating magnetisable particles (such as iron, nickel, or cobalt) into the plastic matrix. This creates a composite plastic element that maintains the flexibility and operational advantages of plastic while adding detectability through the embedded magnetic particles. The composite structure allows the material to be detected by metal detectors even when fragmented, solving the reliability issue without sacrificing operational ease.

The patent applies parameter changes by carefully controlling the size, concentration, and distribution of magnetisable particles within the plastic matrix. By optimizing these parameters, the material achieves sufficient detectability by metal detectors while maintaining adequate mechanical strength and wear resistance. The particle size is kept small enough to not compromise structural integrity but large enough to provide detectable signal.

The patent enables the use of detectable plastic elements in food and pharmaceutical applications by making fragments detectable through embedded magnetisable particles. This allows for monitoring and replacement of worn components before they cause contamination, effectively creating a system where components can be safely used until detection indicates they need replacement, reducing contamination risk.
