U-Type Tunnel Furnace

The U-Type Tunnel Furnace is an efficient continuous industrial baking and heating equipment. It adopts a unique U-shaped return tunnel structure, allowing materials to travel through the furnace in a circulating path. This design significantly extends the heating path within a limited floor space, achieving efficient space utilization and precise energy control.

Product Applications

Food Processing: Continuous baking of large quantities of food products such as bread, biscuits, and pastries.

Electronic Industry: Curing and drying of printed circuit boards (PCB) and electronic components.

Metal Coating: Drying and curing of surface coatings and paint on metal parts and plastic components.

Chemical Materials: Heating, vulcanization, and dehydration treatment of various new materials and rubber products.

Product Parameters

Product Features

Space Saving Design: The U-shaped return structure reduces required factory length by nearly 50% compared with traditional straight tunnel furnaces.

Single-Person Operation: The loading and unloading openings are located on the same side, allowing one operator to complete feeding and collection.

High Efficiency and Low Energy Consumption: The special internal heat circulation system minimizes heat loss and significantly improves energy efficiency.

Precise Temperature Control: Equipped with PID intelligent microcomputer temperature control and multiple independent heating zones, ensuring minimal temperature variation inside the furnace.

FAQ

Q1: What is the biggest advantage of a U-type tunnel furnace compared with a straight tunnel furnace?

A: The biggest advantages are space saving and reduced labor requirements. The U-shaped design shortens the production line length, and the loading/unloading positions are on the same side, allowing operation by one person.

Q2: How is temperature uniformity ensured inside the tunnel furnace?

A: Temperature uniformity is achieved through multi-section independent air circulation systems, optimized air duct design, and PID-controlled hot air circulation.

Q3: Can the conveyor speed and baking time be adjusted?

A: Yes. The equipment uses variable frequency speed control, allowing the conveyor speed to be adjusted according to different material processing requirements.

Q4: What are the installation requirements for the equipment?

A: The installation site should have a level floor, sufficient power supply capacity (or gas pipeline for gas-heated models), and adequate operating space around the loading and unloading areas.

Q5: Which heating method is better for a U-type tunnel furnace?

A: Electric heating provides the most accurate temperature control and is environmentally friendly, while gas heating offers lower operating costs for large-scale production. The best choice depends on available energy sources and operating cost requirements.
