Its optimized design ensures consistent performance, making it ideal for industries requiring precise and efficient freezing solutions.
The plate belt tunnel freezer is specifically designed for the rapid freezing of seafood products such as scallops, shrimp, fish fillets, and fish portions. It is also ideal for freezing fried pastries and portioned meats, ensuring the integrity of delicate food products. The efficient design of this tunnel freezer makes it a reliable choice for industries requiring precision and consistency in their freezing processes.
Plate Belt Tunnel Freezer (Standard)
-
Freezing Capacity 250-800 kg/h (single plate belt), 500-1600 kg/h (double plate belt)
Plate Belt Tunnel Freezer (High Efficiency)
-
Freezing Capacity 400-750 kg/h (single plate belt), 800-1500 kg/h (double plate belt)
- The tunnel freezer consists of an inlet, insulation structure, outlet, conveyor belt, transmission system, air distribution system, evaporator, fan, and an electrical control system.
- Depending on the number of conveyor belts, it is available in configurations such as single plate belt, single mesh belt, double plate belt, and double mesh belt.
- The double plate belt and double mesh belt tunnel freezers divide the insulated structure into two relatively independent freezing chambers using insulated panels. Each chamber is equipped with its own transmission and air distribution systems. This design significantly reduces the required length of the processing area while meeting customer requirements for production processes and output capacity, making it an efficient solution for industrial freezing needs.
Insulation Structure
The insulation structure is constructed using double-sided stainless steel polyurethane panels, assembled for maximum efficiency. It is supported by an integrated rigid base frame, ensuring excellent insulation performance and structural durability.
Access Door
The access door features a PVC door frame molded with integrated foam and equipped with an automatic temperature-controlled electric heating device. This design completely eliminates cold air leakage, ensuring optimal insulation and energy efficiency.
Evaporator
The evaporator is constructed with an aluminum tube and aluminum fin structure, utilizing a combined water and hot ammonia defrosting method. This design meets food safety and hygiene standards while ensuring efficient refrigeration performance.
Conveyor Belt
The conveyor belt features a hardened plate surface that is not only visually appealing but also highly durable. Its strong load-bearing capacity accommodates a wide range of freezing products, making it versatile and reliable for various industrial freezing applications.
Transmission System
The transmission system utilizes precision-cast ductile iron drive rollers, offering an optimal balance of rigidity and flexibility. This ensures long-lasting, stable, and reliable operation over extended periods, even under demanding conditions.
Fan
The fan features a stainless-steel casing and blades, ensuring compliance with food hygiene and safety standards while providing durability and reliable performance in industrial freezing applications.
Air Distribution System
The air distribution system uses the air guide groove specially designed with TOYO’s patent technology. This unique design enables the implementation of a "thermal fluctuation" freezing method, ensuring high freezing efficiency and consistent performance.
