IQF Tunnel Freezer Solutions

Efficient Continuous Freezing Systems for Seafood, Meat, Fruits, Vegetables and Prepared Foods.

IQF Tunnel Freezer

An IQF Tunnel Freezer is designed for continuous, rapid freezing of food products as they travel through an insulated freezing tunnel on a conveyor. Controlled low-temperature airflow removes heat quickly from the product, helping individual pieces freeze efficiently while reducing sticking, excessive dehydration and quality loss.

UFEC provides tunnel freezing solutions for seafood, meat, poultry, prepared foods, fruits and vegetables. Depending on the product shape, production capacity and required freezing performance, different conveyor and airflow configurations can be selected to match the processing line.

Our tunnel freezer solutions can be integrated with complete refrigeration systems and upstream or downstream food processing equipment, helping processors build a continuous freezing line around actual production requirements.

Mesh Belt IQF Tunnel Freezer

A Mesh Belt IQF Tunnel Freezer provides continuous freezing for a wide range of seafood, meat and prepared food products. Products are transported through the freezing tunnel on a stainless steel mesh belt while cold air circulates around the food to achieve efficient heat transfer.

The open mesh structure allows cold air to contact more of the product surface, making this configuration suitable for products such as shrimp, fish fillets, cut meat, dumplings, spring rolls, breaded seafood and other individually separated foods.

UFEC can configure the conveyor width, freezing capacity, tunnel dimensions and refrigeration system according to the customer's product, hourly output and factory layout.

Typical Applications:

Shrimp / Fish Fillets / Seafood / Cut Meat / Dumplings / Spring Rolls / Breaded Foods

Plate Belt Impingement IQF Tunnel Freezer

The Plate Belt Impingement IQF Tunnel Freezer combines a stainless steel plate conveyor with high-velocity cold-air impingement. Air is directed toward the product from both sides to accelerate heat removal and support more uniform freezing.

The stable plate belt provides reliable product transportation and is especially suitable for seafood, meat and other products that benefit from controlled belt contact and intensive airflow. UFEC plate belt tunnel freezer models can be configured for different processing capacities and operating conditions.

This type of freezer is particularly useful when processors require fast freezing, stable conveying and improved control over product dehydration during continuous production.

Typical Applications:

Headless Shrimp / Fish / Shellfish / Cut Meat / Fried Foods / Flat Food Products

Fluidized IQF Tunnel Freezer

A Fluidized IQF Tunnel Freezer is designed primarily for small, loose food products such as fruits and vegetables. High-velocity cold air passes through the conveyor belt and lifts or agitates the product, helping individual pieces remain separated during freezing.

UFEC's fluidized tunnel freezing solution uses staged freezing. The first stage rapidly freezes the product surface and helps prevent pieces from sticking together. The second stage continues deep freezing until the required frozen condition is reached.

This configuration is especially suitable for granular, sliced, diced or strip-shaped foods that need good separation and free-flowing characteristics after freezing.

Typical Applications:

French Fries / Strawberries / Green Beans / Peas / Corn Kernels / Carrots / Cauliflower / Mushrooms / Other Fruits and Vegetables

Complete IQF Tunnel Freezing Solutions

UFEC provides complete IQF tunnel freezing solutions tailored to different food products, processing capacities, freezing requirements, and refrigeration systems.

Choosing the right tunnel freezer depends on more than hourly capacity. Food type, product size, inlet temperature, required outlet temperature, freezing time, belt loading, available factory space and refrigeration conditions all affect the final configuration.

UFEC can provide equipment selection and system design based on actual processing requirements. Tunnel freezers can also be integrated with refrigeration compressor units, condensers, evaporators, cold storage and food processing equipment to form a more complete freezing and cold-chain system.

Available solutions can be designed around different refrigeration requirements, including ammonia, Freon and CO₂ refrigeration systems where appropriate.

Why Choose UFEC for IQF Tunnel Freezing?

Our goal is to work closely with partners to help customers achieve greater success in multiple fields.

Customized Freezing Configuration

Tunnel dimensions, conveyor type, production capacity and refrigeration requirements can be designed around the food product and production line instead of relying on a single standard configuration.

Complete Refrigeration Support

UFEC provides not only IQF freezing equipment but also refrigeration compressors, condensers, pressure vessels and other supporting refrigeration equipment for integrated projects.

Food Processing Experience

Our freezing solutions serve seafood, meat, poultry, fruits, vegetables and prepared food processing, allowing the freezer to be matched more closely with upstream and downstream production requirements.

Project-Based Engineering

From equipment selection and refrigeration-system design to manufacturing, installation and after-sales support, UFEC can provide integrated services for industrial food freezing projects.

Find the Right IQF Tunnel Freezer for Your Product

Different foods require different freezing methods. Before selecting an IQF tunnel freezer, it is useful to confirm your product type, hourly capacity, product dimensions, inlet and outlet temperatures, available installation space and preferred refrigeration system.

Send us your processing requirements, and the UFEC engineering team can help determine whether a mesh belt tunnel freezer, plate belt impingement tunnel freezer or fluidized IQF tunnel freezer is more suitable for your production line.
