    Technical Parameters

    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.

    2. Workflow

    Process Execution

    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.

    Frequently Asked Questions (FAQ)

    Q1: What are the main components of a conveyor belt drying oven?

    The core structure consists of an insulated furnace chamber, a conveyor system (such as Teflon or stainless steel mesh belts), a heating system (electric, gas, or steam), and a precise temperature control system featuring sensors and PID controllers.

    Q2: How do I choose between a Teflon and a stainless steel mesh belt?

    Teflon mesh belts are ideal for sticky materials like films and operate well up to 250°C. Stainless steel mesh belts (SUS304/310S) are preferred for high-temperature and highly corrosive environments where anti-stick properties are not the primary concern.

    Q3: Which heating method offers the highest temperature precision?

    Electric heating, using infrared heating tubes or resistance wires, provides the fastest heating speed and most uniform temperature distribution, making it the best choice for high-precision thermal processing.

    Q4: How does the oven control and stabilize the internal temperature?

    The system utilizes thermocouples or infrared thermometers for real-time monitoring. A PID and fuzzy control algorithm then dynamically adjusts the execution layer, regulating steam flow, fan speeds, or gas valves to maintain temperature stability.

    Q5: What happens to the moisture evaporated during the drying workflow?

    As the heating system evaporates moisture from the film, dedicated exhaust devices continuously remove the moisture-laden air. Fans are often integrated to accelerate airflow and boost overall drying efficiency.
