The Double-layer Production Line is an efficient industrial material conveying system. It adopts an upper and lower conveyor belt structure arranged in a staggered vertical layout. The upper layer is usually used for transporting materials, semi-finished products, or feeding operations, while the lower layer is used for returning empty trays, transporting finished products, or serving as a material transfer channel for the next process.Compared with traditional single-layer conveyor lines, this structure significantly reduces floor space requirements by utilizing vertical space effectively. It has become an essential automated conveying solution for modern lean manufacturing and smart factories.
Electronic Manufacturing:
Used for assembly and testing of mobile phones, computers, home appliances, and other electronic products.
Automotive Parts:
Applied in the assembly of automotive instrument panels, lamps, wiring harnesses, and other components.
E-commerce Logistics:
Used for rapid circulation of material boxes, sorting center operations, and package conveying.
Packaging Industry:
Suitable for product filling, labeling, and transportation of outer packaging cartons.
Food Processing:
Used for food sorting, packaging, and cooling transportation after baking processes.
The Double-layer Conveyor Oven adopts a structure of lower-layer baking and upper-layer return conveying. It is widely used for material drying applications in industrial sectors such as chemical, food processing, electronics, and other manufacturing industries.
The equipment consists mainly of two parts: the conveyor system and the drying oven system. The lower conveyor layer is used for product baking, while the upper layer is designed for material return circulation, improving space utilization and production efficiency.

Standard Functions
Efficient Hot Air Circulation Design
The hot air circulation duct is intelligently designed. Hot air circulates throughout the oven with high coverage, ensuring uniform material drying while reducing energy consumption.
Intelligent Temperature Control
Equipped with PLC touch-screen temperature control system and PID calculation technology, enabling automatic temperature regulation and constant temperature maintenance. The operation is simple with high control accuracy.
Flexible Timing Function
The drying time can be freely set from 1 second to 99.99 hours. After the set time is reached, the heating system automatically stops and a buzzer alarm is activated.
Continuous Operation Capability
The oven features a strong and durable structure, capable of maintaining constant temperature operation for 24 hours a day.
Customized Design
The internal dimensions, body color, maximum temperature, heating speed, load capacity, shelf structure, and number of layers can be adjusted according to actual requirements without necessarily increasing additional costs.
Upgrade Functions
Over-temperature Protection Device
Prevents continuous heating caused by temperature control failure, ensuring the safety of baked products.
Temperature Record Printing
Supports temperature data recording and printing.
Exhaust System
The exhaust outlet can be equipped with an exhaust fan system to improve moisture and volatile gas discharge.
Computer Monitoring and Control
Supports computer-based temperature monitoring, data printing, and centralized control of multiple oven units.
The conveyor system mainly adopts stainless steel chains or stainless steel mesh belts, suitable for different product production requirements. The running speed can be adjusted according to different process requirements.
The heating system uses high-quality stainless steel electric heating elements or far-infrared directional radiation heaters as heating sources. These heating elements feature:
High radiation efficiency
Low energy consumption
Fast heating speed
Small temperature fluctuation
The conveyor oven can be designed with different functional zones, including:
Preheating zone
Constant temperature zone
Temperature reduction zone
Cooling zone
Available temperature ranges:
Room temperature ~200℃
Room temperature ~300℃
The equipment can be customized according to different materials, production capacity, drying processes, and factory layout requirements.
Product Features
Space Saving
The vertical double-layer design effectively doubles space utilization, greatly reducing the occupied production area.
Efficient Material Circulation
The upper and lower conveyor layers work together to achieve a closed-loop flow of “material delivery and empty tray return”, eliminating unnecessary manual handling.
Highly Customizable
The conveyor length, width, layer height, and conveying materials can all be customized according to customers’ product requirements and production processes.
Improved Work Efficiency
The ergonomic design reduces excessive bending and large body movements for operators, lowering labor intensity and improving production efficiency.
Intelligent Integration
The system can be seamlessly integrated with stoppers, elevators, lifting transfer units, and MES systems to achieve fully automated production control.
Q1: Can the upper and lower conveyor layers operate at different speeds independently?
A: Yes. Each layer can be equipped with an independent motor and frequency converter, allowing the upper and lower conveyors to operate in different directions and at different speeds according to production requirements.
Q2: How can the problem of limited visibility or operation obstruction caused by the double-layer structure be solved?
A: During design, the height difference between the two layers is carefully calculated. LED lighting or angled guide plates can also be installed on the upper layer to ensure clear visibility and convenient operation for workers on the lower layer.
Q3: How are empty trays transferred from the lower layer back to the upper layer, or finished products transferred from the upper layer to the lower layer?
A: Normally, vertical lifting conveyors or inclined transition conveyors are installed at both ends of the production line to achieve smooth automatic transfer of materials or trays between the upper and lower layers.
Q4: What are the environmental requirements for the equipment? Is it anti-static?
A: For standard working environments, aluminum profiles or carbon steel structures can be used. For electronic manufacturing workshops, the entire conveyor line can be equipped with anti-static belts and grounding systems. For food or pharmaceutical industries, a full stainless steel structure can be selected.
Q5: Is maintenance of the double-layer production line complicated?
A: No. The equipment adopts a modular design. Key components such as bearings, belts, and motors are equipped with convenient maintenance access points. Regular inspection of belt tension and lubrication of transmission chains are sufficient for routine maintenance.
