Collection: InstaLock LN2 Tunnel Freezer | Liquid Nitrogen Freezer for Shrimp, Durian & Meat
About InstaLock LN2 Tunnel Freezer | Liquid Nitrogen Freezer for Shrimp, Durian & Meat
The InstaLock LN2 tunnel freezer uses liquid nitrogen to freeze products rapidly at very low temperatures, forming tiny ice crystals that protect cell structure. Shrimp, durian and meat retain color, texture and weight after thawing. It suits seafood processors, fruit exporters and meat plants producing individually quick frozen (IQF) products.
How to Choose
- Freezing capacity (kg per hour) matched to your production volume
- Belt width and tunnel length for your product size and line layout
- Liquid nitrogen consumption and operating cost per batch
- Temperature control precision and PLC programming options
- Sanitary stainless steel construction and cleaning access
FAQ
Q: Why use liquid nitrogen for freezing instead of a mechanical freezer?
A: Liquid nitrogen freezes products in minutes at very low temperatures, creating smaller ice crystals, reducing dehydration and preserving color, texture and flavor better than slow mechanical freezing.
Q: Which products can be frozen in the InstaLock tunnel?
A: Shrimp, seafood, durian, fruits, meat, poultry and other high-value foods that need individual quick freezing without sticking together.
Q: How fast is freezing in an LN2 tunnel freezer?
A: Products move through the tunnel on a continuous belt and freeze within minutes, depending on product thickness, temperature settings and belt speed.
Q: What is the main operating cost?
A: Liquid nitrogen consumption is the primary operating cost, so selecting the right capacity and optimizing belt speed and temperature settings helps control the cost per kilogram of frozen product.
