Single-Drum Spiral Freezer
Lynxcool's Single-Drum Spiral Freezer significantly optimizes your food freezing workflow. Designed for high-efficiency operation and made in China, this machine sets the industry benchmark for continuous single-quantity freezing. Designed for high-volume processors, it freezes products individually within minutes, eliminating clumping and deformation associated with traditional methods. With throughput rates ranging from 200 kg/h to over 5,000 kg/h, our spiral freezer maximizes production capacity while minimizing your factory footprint.
Why Choose the Lynxcool's Single-Drum Spiral Freezer?
1. Maximized Space Efficiency
Unlike traditional tunnel freezers, the single-drum spiral design stacks the conveyor belt in a continuous helix. This allows for a significantly longer belt length within a compact footprint.
Space-Saving: A 500 kg/h unit occupies roughly the same floor area as two parking spaces.
Volume Reduction: Cuts refrigerated enclosure volume by 50–70% compared to equivalent tunnel freezers, drastically reducing insulation and energy costs.
2. Superior Product Integrity
Our high-velocity recirculating air system blasts cold air at 3–5 m/s across the product layer. Combined with operating temperatures of −30°C to −40°C, this achieves rapid surface crust-freezing. The result? Individually separated, free-flowing products with zero clumping—perfect for direct packaging.
3. Maintenance & Hygiene Built-In
Self-Stacking Belt: The positive drum drive system eliminates belt slip and reduces tension to near zero, extending belt life by 3–5 years.
Hygienic Design: Full AISI 304/316L stainless steel construction meets EHEDG and NSF standards. The open-frame design allows for full CIP (Clean-in-Place) and manual wash-down access, ensuring strict food safety compliance.

Optimized for Diverse Food Applications
The Single-Drum Spiral Freezer is engineered to handle the specific challenges of various food categories:
Meat and Poultry: Perfect for burger patties, nuggets, and meatballs. The gentle handling preserves shape, while rapid freezing locks in juiciness.
Seafood: Rapid crust formation prevents moisture loss in shrimp, scallops, and fish fillets, preserving texture and color. Ammonia-compatible models available.
Bakery and Ready Meals: Ideal for croissants, par-baked goods, and prepared dishes. The system prevents deformation of delicate dough products.
Convenience Foods: The gentle self-stacking mechanism is perfect for fragile dumplings, spring rolls, and dim sum, preventing wrapper cracking.
Fruits and Vegetables: High-density freezing for berries, peas, and corn ensures free-flowing output without cell damage.
Our Services and Advantages
1. Factory-Integrated and Tested
Every Single-Drum Spiral Freezer is assembled and factory-tested in our China production facility. We don't just ship a machine; we ship a verified solution. Each unit undergoes:
Refrigeration system leak testing.
Belt and drum run-in tests.
PLC logic verification.
Performance data recording at rated conditions.
2. Competitive "Made in China" Advantage
By manufacturing in China, we offer fully engineered, food-safety-certified IQF solutions at 25–40% below equivalent European alternatives, without compromising on quality or engineering support.
3. Application-Specific Engineering
No two products are the same. Our engineering team conducts a product-specific freezing time analysis to configure the exact drum diameter, tier count, and belt speed required for your specific SKU, guaranteeing performance from day one.
