Freeze Tunnel for Fish, Meat & Crayfish | Industrial Freezer

Freeze Tunnel for Fish, Meat & Crayfish | Industrial Freezer

Key Advantages

• True Continuous Operation for Maximum Throughput
  Designed for non-stop, 24/7 production. Products are continuously fed into the tunnel and discharged as individually frozen units, creating a seamless flow that eliminates batch waiting times and dramatically increases overall plant throughput. This continuous operation integrates perfectly with upstream processing and downstream packaging lines.
  
  

• Ultra-Rapid Freezing for Premium Quality Preservation
  Employs high-velocity, ultra-low-temperature airflow (down to -40°C) that quickly extracts heat from all surfaces of each product. This quick freezing minimizes ice crystal formation, preserving cellular structure and preventing moisture loss. For delicate seafood like shrimp and fish fillets, this means superior texture, flavor, and appearance upon thawing.
  
  

• Uniform Freezing Across All Products
  Features a precision-engineered multi-zone airflow system that ensures consistent temperature and air velocity throughout the tunnel. This eliminates hot spots and guarantees that every product—regardless of its position on the belt—receives the same intensive freezing treatment, ensuring batch-to-batch consistency.
  
  

• Flexible Design for Diverse Seafood Products
  Adaptable to a wide range of seafood types and sizes—from small shrimp and scallops to whole fish and thick fillets. Adjustable belt speed, airflow, and temperature profiles allow you to optimize the freezing parameters for different products, ensuring perfect results across your entire product line.
  
  

• Fully Customizable to Your Production Volume
  Each tunnel quick freezer is engineered to match your exact throughput requirements. We customize the tunnel length, belt width, and capacity based on your target hourly output and specific product freezing time needs, ensuring a perfect fit for your production scale.

Our company one-stop set of quick-frozen solutions, using domestic and foreign advanced refrigeration design concept multiple parallel units, no barrel no pump technology, through the PLC in the program automatic energy adjustment to match the ever-changing cooling cooling that the refrigeration system maintain the best efficiency, to achieve energy saving, reduce operating costs.

1. Multiple units are connected in parallel and multi-level energy regulation is used to achieve timely and reasonable matching according to the actual refrigeration capacity required for production, which saves more than 30% energy compared with a single unit.

2.It can match multiple evaporators to achieve one machine suitable for different evaporation temperatures, making the refrigeration system run in the most energy-saving working state.

3. Adopt high-quality compressors and accessories from home and abroad, with reliable performance, stable operation and long service life.

4. Simple design, the refrigeration main unit, accessories and controls are concentrated in one body, which fully saves the machine room space and is extremely convenient for operation and maintenance.

5. The use of fault separation technology can ensure that when some machines fail, other machines can still operate normally, ensuring normal and continuous production for customers.

STC series evaporative condensers are the latest type of evaporative condensers developed by our company by absorbing the latest technologies and manufacturing processes at home and abroad. They are one of many types of condensers and are widely used due to their energy and water saving, high efficiency and low operating cost.

When the equipment is running, the refrigerant in the coil is reversely exchanged by the cooling water from top to bottom and the natural air from bottom to top, and the heat is taken away from the air; the water passing through the coil flows into the packing layer and then flows into the water pan after being cooled. The small water droplets passing through the top layer are collected by the water collector, thus reducing the water escape rate.
