Self-stacking spiral freezer is a continuous freezing system that uses a self-supporting spiral belt to create multiple freezing levels without a traditional spiral drum. The belt forms and supports the spiral path itself, allowing efficient use of vertical space while maintaining continuous product conveying and freezing.

The main difference is the belt support structure. A traditional spiral freezer typically uses a central drum to support and guide the spiral belt, while a self-stacking spiral freezer uses a self-supporting belt structure. This design can reduce mechanical components, simplify cleaning and maintenance, and provide a more compact equipment layout.

Self-stacking spiral freezers can be used for a wide range of food products, including meat, poultry, seafood, prepared foods, bakery products, dumplings, spring rolls, meatballs, chicken products, shrimp, fish, and other individually quick frozen (IQF) products. The actual freezing configuration depends on product characteristics and production requirements.

Yurnfreeze self-stacking spiral freezers can be configured for approximately 300–8,000 kg/h, depending on the product, inlet and outlet temperatures, freezing time, belt width, refrigerant conditions, and required product temperature. The final capacity is determined through application-specific engineering calculations.

The self-stacking design reduces the need for a traditional central drum and uses a food-grade stainless-steel belt structure. The freezer can also be configured with a CIP cleaning system and compressed-air defrosting system to support cleaning, defrosting, and routine sanitation. The final cleaning configuration depends on the production line and hygiene requirements.

Yes. Yurnfreeze self-stacking spiral freezers can be configured according to product characteristics, required capacity, freezing time, inlet and outlet temperatures, available floor space, belt width, refrigerant type, and production-line layout. Options such as CIP cleaning and different conveyor configurations can also be considered according to the project requirements.

The appropriate freezer configuration depends on several factors, including product type, product size and weight, production capacity, inlet and target outlet temperature, required freezing time, belt width, available installation space, and refrigeration conditions. Yurnfreeze can evaluate these parameters and recommend a suitable freezer configuration based on your production requirements.
