Features
- Hygienic stainless steel construction.
- Cryogenic spiral freezer is custom designed to meet your specific requirements.
- IQF spiral technology is characterized by transporting food products around a rotating drum on a conveyor belt using the principle of fast and cold air circulation that flows horizontally and is guided over the product. Our unique and efficient airflow results in faster freezing times, less product dehydration, and higher quality and yield.
- Our meticulous attention to detail ensures that the spiral freezing machine is optimized for all applications, ranging from raw ingredients to ready-to-eat foods.
