Self-Stacking Spiral Freezer
Square’s self-stacking spiral freezer is a compact and hygienic freezer design. Compared to the traditional low-tension spiral freezer, the self-stacking spiral freezer eliminates the rails supporting the belt, which means up to 50% more freezing output with the same footprint.
The conveyors are almost 100% accessible for cleaning thanks to the elimination of the belt rail and drum. The freezer has combined the state-of-the-art clean-in-place (CIP) system.
This open and accessible structure improves hygiene, minimizes downtime for maintenance, and prolongs equipment lifespan by preventing waste accumulation.
- Customized to client specifications
- Capacity ranges from 300kg to 5000kg/hr
- Efficient, Energy-Saving, Easy Cleaning

Product Features
Why Choose Square's Self-Stacking Spiral Freezer
Self-Stacking Belt
Our self-stacking spiral freezer features a self-stacking belt, chain-driven system, and vertical airflow.
The food can be frozen in a shorter time and better quality. The self-stacking spiral freezer meets the highest hygiene and energy-efficiency standards.
The self-stacking belt is driven by a chain system and operates completely on rolling balls. The resistance and noise caused by running the chain are reduced, so smaller motors can drive the system.
The belt is not in tension in the run. The belt is less likely to be stretched and deformed. Self-stacking belt stacks on the top of each otherโs side links.
This self-stacking feature eliminates the rails supporting the belt.
Self-contained Freezing Zone
The unique belt design contains the product in a self-contained freezing zone, for gentle and uniform handling and superior hygiene.
The vertical airflow of high velocity touches the product through all stacks, providing an even, quick, efficient freezing result.
The special holes on the side links also introduce cold air into the product zone and create turbulence. This provides uniform product temperature across the belt and increases the heat-exchanging efficiency.
The centrifugal fans on the top of the coil suck the cold air from the coil and push the high-velocity air down through all belt tiers.
Efficient Evaporator
The design was simulated with European professional heat exchanger software.
All tubes are expanded hydraulically rather than mechanically. More uniform expansion and tighter fit between tube and fins. Improved heat exchanging performance.
Variable fin pitch is used to delay the frost formation on the fin surface. Longer frosting interval.
Easy access and cleaning
Tube material: Stainless steel, Aluminum
Fin material: Aluminum
ADF System
The ADF system blows pulses of pressurized air of high velocity repeatedly over the evaporator fins to remove the frost while the products continue to run in the freezer.
The heat transfer efficiency is significantly improved. Air Defrosting can extend production runtime by 150 to 200% by eliminating frost buildup on the evaporator.
Multiple Automatic Cleaning Systems
The design eliminates the belt-supporting rails and cages. It is hygienic and easy to clean.
The self-stacking freezer provided multiple automatic cleaning systems. They are PZC, PZE, and CIP. PZC cleans the product zone that is in direct contact with the product.
PZE cleans the product zone and coil. CIP is the full mode. It cleans product zones, coils, enclosures, and structures.
The systems have multiple cleaning programs for customers to choose from, including lathering, rinsing, disinfectant spraying, and belt drying.
The self-stacking freezer is ideal for quick freezing of fried food, ready meals, and pastries.
