Tunnel Freezer vs. Fluidized Bed Freezer August 18, 2025 Tunnel Freezer IQF fluidized bed freezer There are two types of IQF equipment commonly used in frozen food processing — Tunnel Freezer and Fluidized Bed Freezer. Tunnel Freezer The products are placed on a conveyor belt and pass through a long tunnel with continuous cold air circulation. Suitable for larger-sized or irregular-shaped products, such as whole fish, meat blocks, bakery products, etc. It provides uniform freezing but generally requires more space and has a higher energy consumption compared to fluidized systems. Fluidized Bed Freezer Designed for small, particulate, or cut products such as French fries, peas, diced vegetables, shrimp, etc. Cold air is blown upward through a perforated belt, suspending the product in a “fluidized” state, preventing clumping and ensuring true IQF effect. Offers high efficiency, shorter freezing time, and excellent product quality retention. Summary If your product is small and granular, the Fluidized Bed Freezer is the best choice. If your product is large, block-shaped, or irregular, a Tunnel Freezer may be more suitable. fluidized bed freezerIQFTunnel freezer You Might Also Like May 29, 2024 Specific advantages of vacuum frying technology on the nutrition preservation Specific Advantages Of Vacuum Frying Technology, The Nutrition Preservation Of Vitamins And The… Read More May 29, 2024 How to choose the right method for sterilizing canned food: immersion water vs. water shower Canning is an age-old technique of preserving food that has been used for centuries.
