Single Spiral Freezer
Single Spiral Freezer

The low-tension spiral freezer with single drum produced by Square Technology is applicable to individual quick frozen of granulated and small-piece food. However, the large-scale freezing devices of which also apply to individual quick frozen of large-sized frozen food such as the prepared meals, whole chickens, whole fish and so on. The height of infeed and outfeed position is adjustable in the low-tension spiral freezer to match the production lines of customers before and after, and it can also be supplied with matched conveyors.

  • The spiral freezer is equipped with a high efficiency sanitary evaporator, using the latest liquid supply method, which makes the heat exchange efficiency more than 20% higher than the traditional freezers.
  • The spiral freezer uses a symmetrical and smooth circular air duct design which enhances the heat exchange effect.
  • We equip with food-grade stainless steel mesh belt and plastic modular belt with the spiral freezer according to different requirements of various products.
  • The spiral freezer is equipped with an intelligent central control system, automatic detection and alarm light device, which is convenient for users to operate and maintain.
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 exhanging performance. Variable fin pitch used to delay the frost formation on the fins surface. Longer frosting interval. Easy access and cleaning Tube material: Stainless steel, Aluminum Fin material: Aluminum
Finite Element Analysis
When designing a spiral freezer, structural analysis is performed to ensure its structural integrity during operation.
