tunnel furnace for thin film curing.png

Low Temperature Continous Tunnel Product for Thin Film

Mesh Belt Continuous Thin Film Drying Tunnel Oven/Tunnel furnaces for thin film products must combine corrosion-resistant materials, heating methods, precise temperature control, and environmentally friendly features to meet industry requirements for throughput, quality, and environmental protection. Model selection should be based on the user's production needs, budget, and supplier's technical capabilities, with a focus on materials, heating methods, temperature control accuracy, environmental protection features, and after-sales service. Energy conservation, standardization, and environmental upgrades will become key trends in the industry's future.

    Structure and Operation Principle

    1. Core Structure

    Furnace: Constructed of high-temperature-resistant stainless steel (such as SUS310S) or welded carbon steel, with internal insulation panels (such as ceramic fiber modules) and air distribution plates. Air inlets and temperature control devices are located at the top and bottom, and heating devices (electric, gas, or steam) are installed on the side walls. Air outlets and exhaust devices are located at both ends.

    Conveyor:

    Teflon mesh belt: High-temperature resistant (above 250°C), anti-stick, and wear-resistant, suitable for materials prone to adhesion, such as films.

    Stainless steel mesh belt: Made of 304/310S, high-temperature and corrosion-resistant, suitable for high-temperature environments.

    Heating System: 

    Electric heating: Infrared heating tubes or resistance wires provide fast heating and uniform temperature, suitable for high-precision requirements.

    Gas heating: Low cost, but requires exhaust gas treatment facilities such as dust collectors, desulfurization and denitrification equipment.

    Steam heating: Requires boiler support, has a moderate cost, and is suitable for companies with a steam source.

    Temperature Control System:

    Sensor: Thermocouples or infrared thermometers monitor temperature in real time.

    Control Algorithm: PID control combined with fuzzy control dynamically adjusts heating power and conveyor speed. 

    Execution Layer: Temperature stability is achieved by adjusting steam flow, fan speed, or gas valves. 

    1. Workflow

    The film enters the oven via a conveyor belt. The heating system generates hot air or radiant heat, which exchanges heat and moisture with the film, evaporating moisture. An exhaust device removes moisture. Some designs use fans to accelerate air flow, improving drying efficiency. The cooling section uses natural cooling or fans to reduce temperature, ensuring that the film meets winding requirements after exiting the oven.

     

    Material Selection

    1. Furnace Material

    Main Body: SUS310S stainless steel (high-temperature and corrosion-resistant) or carbon steel with ceramic fiber cloth insulation.

    Insulation:

    Ceramic fiber modules: Temperature resistance exceeding 1000°C, low thermal conductivity, and excellent thermal insulation performance.

    MGF insulation: Thermal conductivity as low as 0.014 W/m·K, temperature range -60°C to 250°C. 

    1. Conveyor Belt Material

    Teflon mesh belt: Anti-stick and high-temperature resistant, suitable for easily adhered materials such as films.

    Stainless steel mesh belt: Made of 304/310S, high-temperature and wear-resistant, suitable for high-temperature environments.
