Liquid nitrogen contact causes immediate vaporization, pulling heat away 5-10 times faster than standard methods. This rapid temperature drop pushes prawn through its critical ice crystal phase (0 to -5°C) in minutes. The ultra-fine ice crystals prevent cellular rupture, minimizing drip loss upon thawing and perfectly maintaining the prawn's firm texture and ocean-fresh taste.

Food grade stainless steel
The conveyor system is built with food-grade SUS304 stainless steel, offering high strength and excellent corrosion resistance for marine environments. Thickened components ensure extended service life and reliable performance.
Up and down lifting structure
The split lifting design allows the chamber to be elevated for complete access. This facilitates rigorous cleaning and complies with HACCP standards for premium seafood processing.
Independent fan
Zone-specific independent fans guarantee uniform temperature distribution without cross-interference. This ensures every prawn receives consistent, high-quality freezing.
Actual production cases
Perfect for prawn, lobster, scallops, and other high-value shellfish. Also ideal for premium fish fillets, and prepared gourmet foods. Essential for luxury seafood lines requiring top quality.
