IQF Fluidized Tunnel Freezer
Cutting-edge European design. Four-dimensional airflow — products pass through in a suspended state.
- 4D airflow suspension
What The IQF Fluidized Tunnel Freezer Does
Howcool IQF Fluidized-Bed Freezers suspend small, uniform products (peas, berries, diced vegetables, shrimp) in a bed of high-velocity cold air — each piece freezes individually (IQF) without clumping. Delivers the highest quality free-flowing frozen product with the smallest ice crystals and best cell-structure preservation.
Two-stage design: stage 1 fluidization freezes the surface (crust forms in seconds), stage 2 completes the core freeze. Typical throughput 500-3,000 kg/h. Product size range 5-30mm. Stainless-steel perforated fluidization plate with adjustable air velocity. Integrated metal detector and automated weighing systems available.
Inspired by cutting-edge European design. The latest fluidized quick-freezing technology — a revolutionary solution. Unique four-dimensional airflow technology allows products to pass through the quick-freezing zone in a suspended state.
Why Buyers Choose This Model
True IQF Output
Every piece freezes individually — no clumping, free-flowing final product. Best quality for retail-packaged frozen vegetables and berries.
Highest Freeze Speed
Products fully surrounded by cold air on all surfaces — core temp -18℃ in 5-15 min. Smallest ice crystals preserve cell structure.
500 – 3,000 kg/h
Industrial capacity for export-grade frozen vegetable/fruit processors. Two-stage design maximizes throughput.
Small Product Ideal
Peas, corn kernels, diced carrots, berries, shrimp, small fish. Product size 5-30mm. Uniform shape required.
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.
