The Iqf Spiral Freezer is designed for food processors that need high freezing efficiency within limited floor space. Its compact, multi-layer spiral structure occupies about one-third to one-half less space than conventional freezers of similar capacity. Both top-blow and lateral-blow airflow are available, while adjustable freezing times from 20 to 90 minutes support products with different sizes, temperatures, and processing requirements.
The system handles prepared foods, small packages, cross-cut meats, ice cream, seafood, fruits, and vegetables. Its flexible configuration helps manufacturers simplify production while maintaining stable product quality across delicate produce and heavier meat products.

Product Features
1. Compact Footprint: The multi-layer spiral arrangement increases usable belt length without demanding a large installation area, making better use of valuable factory space.
2. Flexible Processing: The Iqf Spiral Freezer supports adjustable residence time, customizable infeed and discharge directions, and smooth integration with frying, packaging, or other processing lines.
3. Hygienic Operation: An aluminum-alloy evaporator with easy-clean fins helps reduce bacterial buildup, while the high-speed cleaning system quickly dries the conveyor belt.
4. Durable Construction: SUS304 stainless steel, mechanical and electrical safety protection, anti-slip tray stoppers, and fewer replaceable parts support dependable operation and lower maintenance costs.
Adjustable airflow and residence time also help operators match freezing intensity to each recipe, reducing unnecessary handling while supporting consistent texture, appearance, and throughput across frequent product changes during daily production.
For processors managing multiple frozen-food categories, the Iqf Spiral Freezer offers a practical balance of space efficiency, product flexibility, hygiene, and reliable daily performance.
Q&A
Q: What temperature is IQF stored at?
A: An IQF freezer ensures products rapidly pass through the "maximum ice crystal formation zone," completing the quick-freeze process once the core temperature hits -18°C. Typically, these IQF freezing systems operate at ambient temperatures ranging from -15°C to -35°C to maintain peak efficiency.
Q: What is a spiral freezer?
A: A spiral freezer uses a continuously rotating conveyor belt arranged in tiers to freeze food rapidly within a compact space.
Q: What is the typical operating temperature of a Iqf Spiral Freezer?
A: Most spiral freezers operate between -30°C and -40°C, depending on product requirements and freezing capacity.
