In supermarket or restaurant freezers, you may notice shrimp that are clear, individual, and separated, unlike traditional frozen shrimp that stick together.
Behind this is the IQF tunnel freezer, which allows each shrimp to freeze quickly, retain moisture and freshness, and improve production efficiency. It’s the preferred choice for modern seafood processing plants.
Shrimp Freezing Process
1. Cleaning and Grading — Quality from the Source
Fresh shrimp are cleaned, peeled or split, and graded by size. Each shrimp is prepared to be uniform and consistent, laying the foundation for effective freezing.
2. Pre-cooling — Preparing for Rapid Freezing
Before entering the freezer, shrimp are pre-cooled to an optimal temperature to minimize ice crystal damage and ensure even freezing.
3. IQF Tunnel Freezer — Individual Freezing to Preserve Freshness
Shrimp are evenly spread on the conveyor belt and enter the tunnel with high-speed cold air, like a “freezing marathon”:
Rapid cold air removes heat quickly
Each shrimp freezes individually, without sticking together
Freezing time is precisely controlled to lock in moisture and texture
4. Packaging — Attractive Appearance, Stable Quality
Frozen shrimp remain separated and can be packaged directly or portioned. The final product looks great and maintains stable quality, ideal for export or retail.
