Pass Through Tunnel Oven

A Pass Through Tunnel Oven is an industrial-scale continuous drying and heating system. It allows materials to continuously pass through the heating tunnel via conveyor belts, mesh belts, or overhead chain conveying systems. The equipment adopts heating methods such as far-infrared radiation, hot air circulation, or microwave heating to achieve rapid and uniform baking, drying, curing, or heat treatment of materials.

FAQ

Q1: What types of conveying systems are available for the Pass Through Tunnel Oven?

A1:The equipment supports various conveying methods, including stainless steel mesh belts, Teflon mesh belts, chains, rollers, and overhead chain conveyors. The suitable conveying system can be selected according to the material shape, weight, and processing requirements.

Q2: How does the tunnel oven ensure uniform temperature distribution over long distances?

A2:The oven adopts multi-zone independent temperature control combined with high-power hot air circulation systems and optimized airflow channel designs, ensuring temperature differences within ±3℃ throughout the heating chamber.

Q3: How are exhaust gases and moisture generated during drying processes handled?

A3:The equipment is equipped with independent exhaust ducts and exhaust fans on the top of the oven, which can continuously remove moisture and process gases or connect directly to the factory central ventilation system.

Q4: Does the equipment have energy-saving designs to reduce power consumption?

A4:Yes. The oven body adopts high-density rock wool and aluminum silicate double-layer insulation structures to effectively reduce heat loss. Combined with variable frequency temperature control technology, the system can reduce energy consumption by more than 30% compared with conventional drying equipment.

Q5: Can the tunnel oven be customized according to factory space requirements?

A5:Yes. The total length, machine width, inlet and outlet sections, heating zone quantity, and overall structure can be customized according to production capacity requirements and available installation space.
