IQF Impingement Freezer
Dense high-speed airflow hits top & bottom of product. Penetrates air layer for rapid freezing.
- High-velocity airflow
What The IQF Impingement Freezer Does
Howcool IQF Impingement Tunnel Freezers use high-velocity cold air jets (15-25 m/s) directed perpendicular to the product surface, dramatically increasing the surface heat-transfer coefficient. Typical freeze time is 30-50% faster than conventional tunnel freezers, producing smaller ice crystals and better product texture.
Primary applications: thin/flat products such as shrimp, fish fillets, chicken wings, burger patties, sliced vegetables. Belt widths 600-1,200mm. Capacity 300-2,000 kg/h. Air velocity adjustable per product type. Frost build-up managed by scheduled defrost cycles — fully automated.
Specially designed low-temperature airflow and air duct circulation. Dense high-speed airflow hits top and bottom of the product as it passes through the freezer on the conveyor belt, penetrating the surrounding air layer for efficient rapid freezing.
Why Buyers Choose This Model
30-50% Faster Freeze
High-velocity air jets (15-25 m/s) increase surface heat-transfer coefficient by 2-3×. Forms smaller ice crystals for better texture.
Ideal for Thin Products
Shrimp, fish fillets, chicken wings, burger patties, sliced vegetables. Product thickness up to 40mm.
Adjustable Air Velocity
Variable-frequency fans adjust airflow per product. Prevents lightweight products (like peas) from being blown off the belt.
Automated Defrost
PLC-scheduled hot-gas or water defrost cycles maintain constant freezing performance over 20-hour production runs.
IQF Quick Freezing System Failure Modes
Drip loss and texture damage
High-velocity impingement and fluidised airflow freeze individual pieces quickly enough to keep ice crystals small.
Floor space
Self-stacking and spiral freezers put a long belt into a small footprint — 500 to 4000 kg/h and 1000 to 6000 kg/h respectively.
Line balance
Tunnel freezers from 300 to 5000 kg/h sized to the throughput of the line feeding them.
