Individual Quick Freezing (IQF) tunnels—including fluidized bed mesh belt tunnels for berries and peas, impingement freezers for burger patties, and flighted freezers for shrimp and diced chicken—demand massive thermal extraction at ultra-low temperatures (-35°C to -45°C).
At CSTHEATEXCHANGER, we engineer Heavy-Duty Evaporator Coils and Unit Coolers for IQF Freezing Tunnels. Engineered for high-velocity air blast fluidization, deep multi-row refrigerant evaporation, and progressive anti-frost fin spacing, our IQF coils freeze individual food pieces in minutes, locking in cellular moisture and preventing clumping.
Ultra-Low Temperature Sizing (-35°C to -45°C): Deep multi-circuit tube passes maximize internal boiling heat transfer, dropping product core temperatures in under 5 to 10 minutes.
Progressive Variable Fin Spacing (15mm / 10mm / 7.5mm): Wide fin pitch at the air inlet accommodates heavy incoming food moisture, preventing frost choking and extending shift runs.
High-Static Pressure Aerodynamics (> 250 Pa): High-thrust axial fans maintain intense fluidization air velocity across continuous stainless steel mesh belts.
Sanitary Stainless Steel Construction: Built with electropolished SS304/SS316L casings, seamless tubes, and food-grade washdown compliance.
