Cryogenic freezing tunnel for crust-freezing delicate foods
Enhance your production with rapid crust-freezing, expertly preserving the shape and appearance of delicate food products while maintaining high-speed continuous operations.

Freezes and Crust-Freezes Soft Food Products
The Cryogenic Tunnel Freezer – CFP from The SERAP Group is engineered to deliver unmatched precision in crust-freezing soft and fragile food products. Utilizing a high-speed conveyor saturated with liquid nitrogen, it enables instant freezing, critical for protecting the structural integrity and appearance of products like ravioli, ice cream bars, and filled pasta shells. This tunnel offers versatility in freezing methods, allowing either immersion in a nitrogen bath or an overhead spray system. Ideal for food processing, confectionery, and ready meal industries, it seamlessly integrates into continuous production lines, effectively reducing deformation and product marking. Constructed from robust AISI 304 stainless steel, it is compliant with European standards and designed for enduring performance. Its energy-efficient design, developed in partnership with AIR LIQUIDE, ensures operational cost savings. The Cryogenic Tunnel Freezer – CFP can handle a variety of product types, both solid and liquid, enhancing your production capacity while maintaining quality. For maintenance ease, the equipment is designed with accessibility in mind, simplifying cleaning and reducing downtime. Custom configurations are available to meet specific throughput requirements and product specifications.
