Introduction
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.

Structure
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.
Features
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.
