Project Summary
In July 2026, we completed the installation of another large-capacity double-drum spiral freezer in Jeddah, Saudi Arabia. This unit is one of our largest models, measuring 15 m in length, 5 m in width, and 7 m in height, with a processing capacity of up to 5,000 kg/h for poultry products.
This installation marks the third spiral freezer supplied by Square Technology to this leading global poultry producer. All three units have been installed in the same production facility over the past few years. The customer has consistently expressed strong satisfaction with both our equipment quality and on-site installation services.
Given the customer’s tight production schedule, our installation team worked diligently, often under demanding conditions—and completed the entire commissioning process within just 25 days. This rapid turnaround significantly minimized production downtime associated with integrating the new line.
Phase 1: High-Pitch Tier Design
We designed the spiral tier with a pitch of 135 mm, considerably higher than that of conventional spiral freezers. The increased clearance accommodates a wide variety of poultry products, including chicken breast fillets, nuggets, strips, and even whole birds, while reducing the risk of product jamming or damage.
Phase 2: Four-Evaporator Configuration
The system is equipped with four evaporators, each constructed with stainless steel coils and aluminum-alloy fins. Every evaporatoris fitted with four fans, providing powerful horizontal airflow to ensure rapid and uniform cooling across different product types. During installation, we interconnected all four evaporators on-site. This required the customer only to connect the main ammonia piping at the top of the unit, greatly simplifying the final connection and hook-up process.
Phase 3: CIP (Clean-in-Place) System
The integrated CIP system automates the entire cleaning cycle. After production is completed, the system sprays hot water over the evaporators, fans, both the interior and exterior surfaces of the spiral tower, the belt working surface, and the decking. This is followed by the application of foam cleansing agents and rinse water. After the disinfection stage, the system performs a final water flush. Users can select from several preset cleaning modes.Once a mode is selected, the complete cleaning sequence runs automatically, reducing manual labor while ensuring consistent hygiene standards.
Phase 4: ADF (Air Defrosting) System
The ADF system uses high-velocity air to rapidly remove frost from the evaporator surfaces. It operates continuously according to a preset schedule and covers the entire evaporator area. This enables more efficient evaporator utilization and extends the effective operating time between defrost cycles.
In this system, an air dryer conditions compressed air from the main compressor. Using filters, it achieves a pressure dew point of –40°C, with a maximum delivery temperature of +30°C. The dried air is stored in an air receiver and then directed to spray nozzles through electrically actuated angle solenoid valves. As the ADF mechanism traverses the evaporator, the nozzles direct the airflow accordingly. At the end of each traverse, a limit switch reverses the motor, which also reverses the direction of the nozzle spray. The ADF system activates automatically whenever the freezer temperature falls below icing conditions.
Conclusion
This project clearly demonstrates Square Technology’s capability to deliver large-capacity spiral freezer solutions tailored to the demanding requirements of the poultry industry. It also further strengthens our growing presence and reputation in the Middle Eastern market.
The customer’s repeat orders—three installations in the same facility—are a strong testament to the long-term reliability, operational stability, and superior build quality of our equipment. Moving forward, we remain committed to providing the industry with increasingly efficient, robust, and hygienic freezing solutions that create lasting value for our clients worldwide.
