Self stacking Spiral Freezer--IQF

Working Principle
In the lower part of the self-stacking freezer, the conveyor belt is entered by the inlet port and is loaded into two special structures.
The two tracks are driven by the drive motor, the two chains do the circular spiral, and the supporting baffles on both sides of the conveyor belt are pout on the drive chain.
Driven by internal and external chains, the conveyor belt completes the conveyor belt’s self-accumulating spiral linear motion. The lubricating system is controlled by PLC.

Structure Features:

Special structural form of self-stacking belt made of food-grade stainless steel suS304 material.
The use of imported special equipment and special technology, a belt with high strength, long life, easy to clean, and so on.
Meet the hygiene requirements of food processing.

Why Choose Yurnfreeze Self-Stacking Spiral Freezer

Self-Stacking Belt

Yurnfreeze Tech Co., Ltd self-stacking spiral freezer is designed for rapid freezing while preserving superior product quality. Featuring a unique self-stacking belt system with chain-driven operation and vertical airflow, it ensures optimal performance while meeting the highest hygiene and energy-efficiency standards.

The chain-driven, self-stacking belt runs smoothly on rolling balls, significantly reducing friction, noise, and energy consumption. This allows the system to operate with smaller, more efficient motors.

Unlike conventional belts, our design eliminates tension during operation, minimizing stretching and deformation. The self-stacking mechanism allows the belt to stack securely without the need for supporting rails, enhancing durability and reducing maintenance.

With faster freezing times, improved product quality, and lower operational costs, our spiral freezer delivers unmatched efficiency and reliability.

Efficient Evaporator

Our heat exchanger is precision-engineered for optimal performance:

Hydraulic tube expansion ensures tighter fin contact and better heat transfer
Variable fin pitch reduces frost buildup, extending operation time
Easy to clean with open-access design
Durable construction: Stainless steel/aluminum tubes with aluminum fins

Designed using advanced European thermal simulation software for reliable, energy-saving operation.

ADF System

Our ADF system uses high-speed air pulses to remove frost from evaporator fins without stopping production, maintaining optimal heat transfer efficiency.

Benefits:

Continuous operation – No downtime for defrosting
150-200% longer runtime by preventing frost buildup
Energy efficient alternative to hot gas defrost

Ideal for spiral freezers and processing lines requiring uninterrupted operation.
