IQF

Ammonia IQF systems use ammonia (NH₃) as the refrigerant to rapidly freeze individual food pieces separately. This technology preserves product quality by freezing items quickly and preventing them from sticking together. IQF stands for Individually Quick Frozen, a freezing method used to freeze food items one at a time instead of in a block. This technology is widely used in the food industry to maintain quality, freshness, and shape of individual products.

 

Key Features:

1. Ammonia Refrigerant

• Natural refrigerant with zero ODP and GWP

• Highly efficient thermodynamics reduce energy consumption and operating costs

• Widely used in large-scale industrial freezing applications

2. Individual Quick Freezing

• Rapid freezing of individual pieces (e.g., peas, shrimp, chicken nuggets)

• Prevents clumping, enabling free-flowing frozen products

3. High-Velocity Cold Air or Fluidized Bed Freezing

• Uses blast freezing with powerful fans or fluidized bed technology for enhanced contact between cold air and product

• Typical temperatures range from -30°C to -40°C

4. Continuous Freezing Process

• Designed for high-throughput, automated lines

• Products continuously move on conveyors or vibrating beds through freezing zones

5. Energy Efficiency

• Ammonia’s excellent heat transfer reduces compressor workload

• Efficient airflow design minimizes energy loss

6. Hygienic and Food-Safe Construction

• Stainless steel components and sanitary design for easy cleaning

• Meets food safety standards (FDA, USDA, HACCP)

7. Flexible Product Handling

• Suitable for a wide range of products: seafood, fruits, vegetables, meat, and bakery items

• Adjustable airflow, temperature, and conveyor speed to optimize freezing for different products

8. Advanced Automation and Controls

• PLC/SCADA control systems for precise monitoring and adjustment

Integrated safety features including ammonia leak detection and emergency shutdowns
