New Type Spiral Freezer

The New Type Spiral Freezer used for individually quick freezing (IQF) various foods. It utilizes a flexible conveyor belt that spirals vertically, allowing products to undergo a long freezing process within a compact footprint. Compared to older models, it offers higher energy efficiency, greater flexibility, superior product quality, easier maintenance, and more intelligent control.

Overview
Recommended Products

Compared to traditional models, this new spiral freezer achieves comprehensive upgrades with five key advantages: high efficiency, flexibility, superior quality, easy maintenance, and intelligent control. It significantly improves energy efficiency, reducing both energy use and operating costs. Highly adaptable, it meets the quick-freeze needs of diverse foods and specifications. Its precise freezing process better retains food flavor, nutrition, and texture for stable end-product quality. Designed for easier maintenance, it simplifies cleaning and inspection while cutting downtime. The built‑in smart control system allows precise freezing regulation, data monitoring, and intelligent management, supporting automated and intelligent food‑processing lines.

Working Steps of Spiral Freezer

Infeed

Product is evenly distributed onto the lower end of the conveyor belt via an infeed.
A spreader is typically used to ensure even distribution and prevent pile-up.

Spiral Ascent

The product enters the freezing zone, composed of multiple tiers of spiraling conveyor belts.
The belt moves in a spiral on a vertical plane, carrying the product upward.

Forced Convective Heat Transfer

Inside the spiral tower, high-power, high-static-pressure fans generate a powerful, uniform stream of low-temperature air. This airflow passes through the ascending product layer in a cross-flow pattern, rapidly extracting heat.

Freezing

During the spiral ascent process, the product's internal moisture rapidly passes through the "maximum ice crystal formation zone," creating fine and uniform ice crystals to achieve rapid freezing.

Discharge

Upon reaching the top of the spiral tower, the product is discharged through the outlet to the next processing stage.

It typically uses a fixed-speed compressor and permanent fixed-frequency fans. The system runs at fixed power regardless of load, leading to high energy efficiency.	Full variable frequency drive (VFD) technology cool on-demand, saving up to 30%-40% in energy compared to traditional fixed-speed units.
Air duct design may be less optimized, leading to uneven heat exchange efficiency.	Utilizes high-efficiency evaporators and optimized air duct design to ensure uniform airflow and maximize heat transfer.
Insulation thinner, leading to greater cold loss.	Employs thicker, high-performance insulation to significantly reduce cold air leakage.
Uses simple relay-based controls, which offer limited functionality.	Equipped with advanced PLC + color touchscreen HMI. Allows precise setting and monitoring of all operating parameters.
Uses simple timed defrost, which can waste energy.	Uses intelligent on-demand defrost. Activates only when necessary, making it more energy-efficient.
It has hard-to-reach areas that make cleaning labor-intensive.	Strictly adheres to hygienic design principles. Extensive use of quick-release panels for easy cleaning.
Airflow distribution may be uneven, leading to variable freezing.	Precise air duct design ensures extremely uniform airflow distribution for highly consistent freezing quality.
