Detecting Contaminants in Frozen Fish & Shrimp – Overcoming Low-Temperature Challenges

2025-08-16

Seafood such as fish fillets, prawns, and squid often require frozen storage at -18°C or lower. At these temperatures, the high water content in the product turns to ice, which can interfere with electromagnetic signals in metal detectors and reduce detection accuracy.

Challenges in Frozen Product Inspection:

Moisture Signal Interference: Frozen water crystals create a “product effect” that can mask small metal contaminants.
Variable Shapes & Sizes: Irregular seafood shapes make consistent inspection more complex.

Best Practices & Solutions:

Low-Temperature-Optimized Metal Detectors: Our cold-environment models use advanced phase adjustment technology to minimize product effect and achieve detection sensitivity of φ0.4 mm stainless steel even at -20°C.
X-ray Inspection for Export Markets: X-ray systems can detect metals, shell fragments, stones, and glass regardless of product temperature or shape, making them ideal for high-value export seafood.
Inspection Point: Install detection equipment at the exit of the spiral freezer or tunnel freezer, where product temperature and condition are most stable.

Shanan Technology’s frozen product metal detectors and X-ray inspection systems are trusted by seafood processors worldwide for their high accuracy, durability, and compliance with global standards.
