Industrial IQF: The CBFI Continuous Tunnel Freezer
The Science of Individual Quick Freezing (IQF)
Beyond Bulk Freezing: Preserving Cellular Integrity Traditional batch freezing often results in "clumping" and large ice crystal formation. CBFI's Tunnel IQF technology utilizes a high-velocity vertical airflow system. By suspending the corn kernels or cobs in a fluidized or semi-fluidized state, we achieve a super-fast thermal exchange. This prevents the sharp-edged ice crystals from piercing the corn's cell membranes, ensuring that when the consumer thaws the product, it retains the "fresh-picked" snap and sweetness.
High-Performance Thermal Engineering
Cascaded Refrigeration & Airflow Precision The CBFI Tunnel Freezer (BF Series) is engineered with high-efficiency finned evaporators and a multi-vane fan system.
Ultra-Low Temperature Sinks: Utilizing R404A or R507 eco-friendly refrigerants, the system maintains a consistent -35°C to -40°C environment.
Aero-Dynamic Air Guiding: The internal air pressure is balanced to ensure that cold air penetrates the "boundary layer" of the food product instantly, reducing the freezing time to just 15-20 minutes depending on the product diameter.
Hygienic Design & Structural Integrity
Sanitary Standards for Global Export To meet international food safety requirements (HACCP/FDA), the entire tunnel interior is constructed from SUS304 food-grade stainless steel.
Full-Slope Drainage: The floor is designed with a specific pitch to ensure that cleaning water and debris are completely flushed out, preventing microbial buildup.
High-Density Insulation: Using 120mm-150mm PIR/PU sandwich panels, we minimize thermal leakage, ensuring the exterior remains at ambient temperature while the interior is a cryogenic vault.
Smart Integration: The "Dark Factory" Concept
Reducing Labor, Increasing Yield The modern corn processing line is moving toward full automation. CBFI's system integrates seamlessly with:
Optical Sorting: High-speed cameras detect discoloration or irregular shapes before the product enters the tunnel.
Automated Defrosting (ADF): Our sensors detect frost buildup on the evaporator coils and trigger a rapid defrost cycle without stopping the production line, maintaining a 98%+ uptime.
Strategic Advantage in the Ready-to-Eat (RTE) Market
As the global demand for frozen organic vegetables surges, the CBFI Tunnel Freezer provides the scalability required for enterprises to move from regional suppliers to national powerhouses. By stabilizing the "Gold Standard" of texture and nutrition, brands can command premium pricing in supermarkets and high-end catering chains.
