Double Spiral Freezer

Double Spiral Freezer

The low-tension spiral freezer with double drums produced by Square Technology is applicable to individual quick frozen of granulated and small-piece food, large-sized frozen food, such as the prepared meals, whole chicken, and whole fish. Double drum spiral freezer positions infeed and outfeed at low, making it convenient for operation and better matching the production lines of customers.


  • 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.
Air Defrost System
The ADF blows pulses of pressurized air of high velocity repeatedly over the evaporator fins while the products continue to run in the freezer. The freezer inside temperature is more stable because of less frost on the fin. Thanks to longer runtime, the production output is increased.
CIP(Cleaning-in-Place)
The system cleans and disinfects the interior of the freezer completely to meet the sanitary requirements of food safety production. Our system design is programmed with tailored CIP recipes to suit various product and needs.
