What The IQF Self-Stacking Spiral Freezer Does
Howcool IQF Self-Stacking Spiral Freezers are the industry-leading solution for high-throughput Individual Quick Freezing of poultry, seafood, bakery, and prepared foods. The stainless-steel belt coils around a central drum in a self-stacking spiral — products stay on the belt without need for external supports, maximizing space efficiency (only 60% of floor area vs. straight tunnels).
Standard capacities: 500 kg/h to 3,000 kg/h. Cooling via ammonia (NH₃) direct expansion or hydrocarbon-brine indirect systems. Typical freeze time: 15-40 minutes depending on product thickness. Belt materials: food-grade stainless steel (304/316) or plastic modular belt for delicate products. CIP (Clean-in-Place) system and automatic defrost standard.
The perfect solution for quick and even freezing. Vertical cold airflow area ensures each product is individually frozen, resulting in continuous large output. Ice crystal formation area ensures products are frozen evenly and quickly, retaining deliciousness and juice.
Why Buyers Choose This Model
500 – 3,000 kg/h Capacity
Ideal for medium-to-large food processors. Modular design allows capacity expansion by adding belt tiers.
60% Floor Space Saving
Self-stacking spiral belt eliminates external belt-support structure. Fits in 50-80 m² footprint vs. 150-200 m² for straight tunnels.
Food-Grade Construction
304/316 stainless-steel frame and belt. FDA/EU food-contact certified. CIP system for wash-down sanitation.
Precise Temp Control
Product core temperature reaches -18℃ in 15-40 min. PLC monitors inlet/outlet temp and belt speed for consistent freeze quality.
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.
