IQF Spiral Freezer
European technology + Howcool advanced concepts. Spiral-rotating conveyor belt.
- European tech spiral design
What The IQF Spiral Freezer Does
Howcool IQF Spiral Freezers combine high capacity with compact footprint. The stainless-steel belt spirals upward around a central drum supported by external tower structure — providing 8-20 tiers of belt in a small floor space. Typical product residence time 15-60 minutes — long enough for deep-freezing of thick products (up to 60mm).
Available in 8 standard models: SD100 (100 kg/h) to SD2000 (2,000 kg/h). Belt widths 500-1,200mm, tier counts 8-20. Drum diameter 2-4m. Ammonia direct-expansion or brine indirect cooling. CIP system, programmable defrost, and PLC monitoring all standard.
Designed and manufactured by our experienced team, combining European technology and Howcool's advanced concepts. The conveyor belt rotates in a spiral, allowing rapid individual quick-freezing.

Why Buyers Choose This Model
High Capacity, Small Footprint
100-2,000 kg/h throughput in 40-100 m² footprint. 8-20 belt tiers maximize throughput per square meter.
Deep-Freeze Thick Products
Long residence time (15-60 min) allows freezing of thick products (up to 60mm) — fish, poultry pieces, bakery.
8 Standard Models
SD100 to SD2000. Detailed spec table with drum diameter, belt width, and freezing capacity for all 8 sizes.
Proven Design
External tower structure simplifies maintenance access. Visible belt path for easy product tracking and jam detection.
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.
