The difference between single spiral freezer and double spiral freezer

2025-06-05

1、 Structure and principle of spiral freezer
A single spiral freezer is a device that uses a screw conveyor and temperature control system to push food from the cold air chamber to the hot air chamber, thereby achieving high-speed freezing. Its main components include feed inlet, transmission shaft, refrigeration compressor, container, and control system. The single spiral quick freezing machine can achieve automatic conveying and temperature control during the processing, with high production efficiency.
Double spiral freezer machine is also a device used for quick freezing of food. It consists of two adjacent conveyor helices, with the upper and lower helices rotating in opposite directions to cool the food inside. Its main components include feed inlet, transmission shaft, cooler, container, and control system. The double helix single freezing machine can adapt to different processing conditions and meet different cooling requirements.
2、 The difference between single screw double screw single spiral freezer
The difference between a single spiral freezer and a double spiral freezer mainly lies in the structure and working principle of the equipment. The single spiral freezer mainly uses a screw conveyor to transport materials and transfer heat, while the double screw freezer cools food through two adjacent helices. Therefore, the cooling effect of the double spiral single freezer is better, but the equipment structure is more complex.
3、 Advantages and disadvantages of single screw double screw single spiral freezer
The advantages of a single screw quick spiral freezer include small footprint, energy savings, and high degree of automation. But its cooling effect is not as good as that of a double spiral single freezer, which can easily cause freezing on the surface of food and affect food quality. The advantages of the double spiral single freezing machine are good cooling effect, short freezing time, and the ability to maintain the quality and taste of food. But the equipment structure is relatively complex and the price is also high.
4、 Scope of application of single screw double screw single spiral freezer
The single spiral freezer is suitable for freezing heat sensitive foods such as fruits and vegetables. The double spiral single freeze machine is suitable for cooling foods that require high quality and taste, such as meat and seafood.
