What The IQF Tunnel Freezer Does
Howcool IQF Straight Tunnel Freezers are the simplest and most cost-effective quick-freezing solution — products ride a continuous belt through a refrigerated tunnel. Standard choice for medium-capacity processors freezing a variety of products: poultry cuts, seafood, vegetables, fruits, dim-sum, ready meals, and bakery.
Modular design: 3m, 6m, 9m, 12m, 15m tunnel lengths available. Belt widths 500-1,500mm. Capacity 200-1,500 kg/h. Single or double belt configurations. Mechanical or ammonia direct-expansion refrigeration. Can be configured as combined chill + freeze tunnel for products requiring pre-cooling.
With a large freezing area and the ability to freeze various types of food including individual freezing, block freezing and plate freezing, the IQF Tunnel Freezer is the ideal freezing equipment. Simple linear layout suits any production line configuration.
Why Buyers Choose This Model
Most Cost-Effective IQF
Simplest design, easiest to operate and maintain. Lowest capex vs. spiral or impingement freezers.
Versatile Product Range
Handles poultry, seafood, vegetables, fruits, bakery, ready meals. Belt speed adjustable 0.2-5 m/min per product.
Modular Length
3m to 15m tunnel lengths. Can be daisy-chained for higher capacity or split into pre-cool + freeze zones.
Easy Maintenance
Straight-belt path simplifies belt replacement and deep cleaning. Access doors along entire tunnel length.
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.
