- Temperature variations: Detection sensitivity can be affected by temperature fluctuations; advanced systems incorporate automatic compensation
- Vibration isolation: Sensitive detection coils must be isolated from production equipment vibration
Rejection Mechanism Engineering
The rejection system is as critical as detection itself. Modern gravity feed systems typically employ:
- Pneumatic flap gates: For free-flowing granular products
- Rotary valves: For products with higher density or abrasive characteristics
- Diverter systems: For applications requiring product stream separation
A recent case study involving a major North American spice processor demonstrated that upgrading from a standard flap gate to a precision pneumatic diverter reduced product waste during reject events by 34% while improving contamination removal effectiveness.
