Ammonia R717/ R504 Refrigeration Cooling System Low Temperature IQF Spiral Freezer with CIP

Product Description

Product Overview

YURNFREEZE Spiral Freezer is designed not only for IQF (Individual Quick Freezing) but also for high-efficiency cooling (IQC) applications.With optimized airflow and spiral belt structure, it can achieve fast and uniform temperature reduction-from 80°C to 10°C or 30°C to 5°C, depending on product type.
Ideal for seafood, meat, bakery, sauces, ready meals, dairy, and even cosmetics cooling or freezing.

Technology Features
· Reliable transmission system for stable operation
· High-strength stainless-steel mesh belt
· Efficient evaporator with 30% higher heat exchange rate
· Double stainless-steel insulated panels for optimum airflow
· CIP automatic cleaning system
· ADF automatic air defrosting for continuous operation
· Optional IQC cooling or IQF freezing mode

Cooling & Freezing Performance
Many products require cooling rather than deep freezing. For example:
· Blueberries: 30°C → 5°C to prevent skin cracking
· Hot pot ingredients & custard: 80-60°C → 10-15°C for quick packaging
· Bakery goods: Rapid cooling after baking to preserve texture and shape
With frequency control and adjustable temperature zones, the system can perform both cooling and freezing in one unit.

Construction & Components

Insulation Library Body

• Material: Stainless steel + polyurethane sandwich panel, panel thickness 0.6mm per side, internal polyurethane high-pressure foamed (German material), filling density ≥42kg/m³.

• Panel thickness: S=120mm, with concave-convex joint connection between panels.

• Door: Reinforced structure with electric heater between door and frame, can be opened at any time; equipped with automatic sensor magnetic switch.

Main Frame

• Material: Rotating cage column support, shaft, transmission gears, and chains are all SUS304 stainless steel, compliant with QS, FDA, and other food certifications.

• Guide rails: Stainless steel covered with wear-resistant polymer composite, ensuring minimal friction.

• All structural parts fully welded.

• Rollers, drums, and guide rails in contact with the mesh belt made of ultra-high molecular weight polyethylene for wear resistance.

Evaporator

• Material: Evaporation tubes and fins made of rust-proof aluminum alloy; outer frame stainless steel, withstand voltage ≥24kg/cm².

• Tube specification: φ25×2.2mm; fin thickness 0.4mm, high flange 10-12mm.

• Variable fin pitch: 20mm at air inlet, 10mm at outlet, ensuring uniform frosting and extended continuous operation of the freezer.

• Efficiency: 30% higher than standard evaporators.

Cold Air Circulation System

• Annular air cooler cabin designed for high wind speed and low pressure loss.

• High-performance fans provide continuous circulating airflow.

• Closed-loop air duct with horizontal airflow design ensures smooth return air, low pressure loss, fast freezing, and low product dehydration.

Conveyor Belt

• High-strength imported mesh belt, meeting American Ashworth standards; smooth surface and long service life.

• Food can be placed directly on the belt for freezing; retractable design with 12mm ribs on both sides to prevent slipping.

• Plate products remain stable during freezing, avoiding collision or damage.

• Material: Food-grade SUS304 stainless steel for hygiene compliance.

• Structure: Mandrel φ5mm, chain piece thickness δ=2mm.
