Project Delivery: Four Self-Stacking Spiral Freezers for DaChan Food
Square Technology engineered and delivered four drumless Self-Stacking Spiral Freezers to DaChan Food (DaChan Great Wall Group), one of Asia’s foremost vertically integrated poultry and food processing groups. Manufactured and factory-tested at Square Technology’s integrated Nantong campus, all four self-stacking units were delivered on schedule to support DaChan’s high-capacity poultry and value-added prepared food production lines.
Regional Benchmark: Multi-Plant Deployment with CP Foods Group in Thailand
Square Technology’s self-stacking spiral freezers are widely deployed by leading poultry processors across both China and Southeast Asia. Prior to the DaChan project, multiple Square self-stacking spiral freezers were installed and placed into continuous full-load operation across three separate poultry processing plants of CP Foods Group (Charoen Pokphand Foods / CPF) in Thailand—the largest poultry processor in Asia.
Across these multi-plant installations, CP Foods recognized the self-stacking systems for their open hygienic structure, mechanical reliability, ease of sanitation, intuitive Siemens PLC/HMI recipe operation, and responsive technical support.
Why Leading Poultry Processors Choose Square’s Self-Stacking Architecture
With more than 40 self-stacking spiral freezers delivered for raw and cooked poultry, meat portions, and ready meals, Square Technology’s drumless design addresses the strictest hygiene and throughput demands in industrial protein processing:
- Drumless Self-Supporting Belt Stack (Up to 50% Higher Capacity in the Same Footprint): By eliminating the central rotating drum and stationary belt support rails, the TitanStack® self-stacking mesh belt forms a self-enclosed freezing zone that increases usable belt tiers and airflow efficiency within a compact footprint.
- 100% Sanitization Access & Automated CIP: Removing the central drum and rail structure eliminates hidden grease and debris traps, allowing the integrated Clean-in-Place (CIP) foaming, rinsing, and sanitizing system to reach every interior surface between production runs.
- Controlled Vertical Airflow for Low Dehydration: High-velocity cold air passes vertically through the enclosed belt stack, ensuring uniform heat transfer across chicken breast fillets, wings, nuggets, and patties while minimizing product moisture loss.
