Industrial refrigeration tunnel TF series

air-cooled

Product overview
A tunnel blast freezer, also known as a tunnel quick freezer, is an efficient continuous freezing solution for high-volume food processing plants. Designed for continuous, high-volume production, it rapidly freezes food while preserving texture, flavor, color, moisture and nutritional value. Products enter one end of the insulated tunnel on a conveyor belt and travel through an extremely cold environment where high-velocity refrigerated air rapidly removes heat so that exiting products reach a core temperature of -18°C or below and are ready for packaging or cold storage.

Types of Tunnel Blast Freezers
Type | Key Features | Typical Applications
Flat Mesh Belt Tunnel Blast Freezer | General-purpose model with a simple, reliable structure. Continuous operation with production capacities from 100–2,000 kg/h. Easy to maintain and suitable for a wide range of products. | Meat, poultry, seafood, meatballs, frozen snacks, prepared meals, bakery products.
Multi-Layer Mesh Belt Tunnel Freezer | Multiple conveyor layers increase the freezing path within a compact footprint, allowing longer freezing times and higher capacity without requiring additional factory space. | Thick meat products, seafood, bakery items, prepared foods, factories with limited installation space.
Vibrating (Fluidized Bed) Tunnel Freezer | Designed for IQF (Individual Quick Freezing). Vibration or high-speed airflow keeps products separated during freezing, preventing clumping and ensuring uniform freezing. | Shrimp, green peas, corn kernels, diced vegetables, berries, small fruits, and other granular products.
Steel Belt Tunnel Freezer | Uses a stainless steel conveyor belt with excellent heat transfer efficiency. Provides stable product transportation, easy cleaning, and long service life. | Fish fillets, shrimp, seafood, flat products, and processed aquatic foods.
Liquid Nitrogen Tunnel Freezer | Uses liquid nitrogen (-196°C) for ultra-fast freezing. Compact design with exceptional freezing speed and optional nitrogen recovery system to reduce operating costs. | Premium seafood, high-value fruits, gourmet foods, ready meals, delicate bakery products, and other high-value food items.
