Air Cooling Tunnel Furnace

The Air Cooling Tunnel Furnace is an industrial automated cooling equipment that uses strong airflow to rapidly reduce the temperature of materials transported through the tunnel conveyor system. It is usually connected to the rear end of a high-temperature baking furnace or sintering furnace. Through forced air convection, the equipment quickly cools high-temperature products after baking to a safe handling temperature or the temperature required for the next production process, enabling continuous production line operation.

Product Applications

Food Processing:

Used for rapid cooling and shaping of baked products such as pastries, bread, mooncakes, and other baked goods after high-temperature baking.

Electronic and Electrical Industries:

Used for cooling PCB boards and electronic components after soldering, encapsulation, or drying processes.

Metal and Plastic Products:

Used for heat dissipation and cooling after spray coating baking of metal parts and plastic products, helping complete the curing process.

Automotive Components:

Used for rapid cooling of automotive parts after heat treatment or coating processes before entering the next production stage.

Technical Parameters

Product Features

Continuous Operation:

The tunnel-type structure enables uninterrupted cooling operation on the production line.

Uniform Heat Dissipation:

Multiple groups of fans provide multi-angle circulating airflow, ensuring no dead zones during the cooling process.

Adjustable Speed:

The variable frequency speed control system allows adjustment of conveyor speed to meet different product cooling time requirements.

Energy Saving and High Efficiency:

The optimized air duct design reduces air consumption while achieving excellent cooling performance.

Seamless Integration:

The height and width of the equipment can be customized to match the upstream and downstream production equipment.

FAQ

Q1: What is the difference between an air cooling tunnel furnace and a drying tunnel furnace?

A1:A drying tunnel furnace uses a heating system to increase temperature and promote moisture evaporation or material curing. In contrast, an air cooling tunnel furnace works in the opposite way. It does not contain heating elements and only uses fans to blow air to reduce the temperature of high-temperature products.

Q2: Can the air cooling tunnel furnace still achieve effective cooling if the workshop temperature is high?

A2:The standard model uses ambient air from the workshop for cooling. If the workshop temperature is too high or the product requires extremely low cooling temperatures, a cold air system (air-conditioning cooling) or water-cooled jacket system can be added.

Q3: Can the conveyor medium, such as mesh belt or chain, be selected according to the product characteristics?

A3:Yes. Different conveyor options can be selected according to product requirements, including:

Teflon mesh belt: Anti-stick and corrosion-resistant, suitable for products requiring non-stick transportation.

Stainless steel mesh belt: High-temperature resistant and suitable for heavy-load applications.

Flat belt: Provides smooth transportation and prevents product scratches.

Q4: Where does the energy consumption of this equipment mainly come from?

A4:The energy consumption is very low. Since there are no electric heating elements, power consumption mainly comes from the conveyor motor and high-power cooling fans. It is an energy-saving type of industrial cooling equipment.

Q5: How should the equipment be maintained and cleaned?

A5:Regularly clean the air inlet filter to prevent blockage. Check the conveyor belt tension every month and lubricate the bearings regularly. The internal cooling channel is usually equipped with cleaning access doors for convenient wiping and maintenance.
