Tunnel Drying Oven

The tunnel drying oven is a continuous drying and baking system designed to process products on a conveyor line. Products are continuously transported through the heated tunnel chamber for drying, curing, baking, or heat treatment processes. This continuous operation significantly improves production efficiency, increases output capacity, and ensures consistent product quality.

Heat conduction design: Heating elements such as electric heating tubes are evenly installed on the top or two sides of the cabinet to transmit heat through thermal radiation and convection. Conveyor speed adjustment: The conveying speed can be modified based on material properties to guarantee adequate heating. Zoned temperature control: The equipment is normally split into three zones including preheating, constant temperature and cooling zones to avoid thermal shock.

High Efficiency:The continuous conveying system transports materials through the heating zone rapidly, greatly boosting production efficiency.

Uniform Heating: Equipped with a precise temperature control system and hot air circulation design, it ensures even heat distribution on materials and improves product quality.

Energy Saving & Environmental Protection: Adopting advanced heat recovery technology, it cuts down energy consumption and exhaust emissions, complying with environmental protection standards.

Wide Adaptability: Parameters such as heating temperature, conveying speed and air volume can be adjusted to match the characteristics of various materials and production process requirements.

Easy Operation:The automatic control system simplifies operating procedures, reduces labor costs and guarantees operational safety.

The tunnel drying oven is a drying equipment suitable for mass and continuous production with a wide range of industrial applications. Its major application fields are as follows:

• Pharmaceutical industry: Drying, sterilization and depyrogenation of glass containers such as ampoules and vials;
• Food industry: Drying, baking, crisping and other processing procedures for food products;
• Chemical industry: Drying, dilution, synthesis and other processes of chemical raw materials;
• Electronics industry: Drying and curing of LEDs, LCDs, circuit boards, electronic components and other parts;
• Other industries: Drying processes for textiles, metal products, printing materials, silicone rubber, instruments and meters, etc.

This tunnel drying oven mainly comprises two core assemblies: the conveying system and the drying furnace body.

Conveying System Equipped with dual-side chain transmission structures to effectively avoid material deviation during transportation. The conveying speed is adjustable to match different processing requirements of materials.

Sectional heating design with separate electric control cabinets for each zone, facilitating convenient individual operation and parameter setting.

Multi-section independent PID temperature control systems are deployed inside the furnace to maintain consistent and even temperature distribution throughout the working chamber.

Heating elements are evenly mounted on the top or two sides of the furnace, transferring heat via thermal radiation and hot air convection to ensure uniform heating of workpieces.
