304 Stainless Steel Direct Gas Tunnel Oven with Independent Temperature Probes and Rockwell PLC Control System
This industrial direct gas fired tunnel oven utilizes ribbon burners positioned above and below conveyor belts to directly transfer heat to products. The combustion flames radiate energy throughout the baking chamber, efficiently heating both the air and products.
Each burner receives a precisely controlled mixture of gas and air, with flow rates determining combustion intensity and maintaining precise temperature set points.
The oven features sophisticated temperature monitoring with three independent temperature probes for both upper and bottom fire in each zone. The system calculates average values from these measurement points to minimize errors and achieve exceptional temperature control accuracy.
| System | Features & Specifications |
|---|---|
| Air Supply System | Each zone equipped with independent air supply system for precise combustion control |
| Gas Supply System | Independent gas supply per zone with dual electromagnetic slow-opening valves to prevent sudden gas connection |
| Exhausting System | Two sets of exhaust dampers per zone (upper and lower) with independent inverters for real-time exhaust volume adjustment |
| Ignition System | Automatically controlled by burning program controller with individual burner selection via touch screen; flame detection ensures automatic gas cutoff when no flame present |
| Control System | Rockwell PLC core with distributed IO control for regional modular operation; multiple safety monitoring systems ensure operational safety and stability |
The oven is constructed from durable 304 stainless steel, providing excellent corrosion resistance and longevity in industrial baking environments.
- 304 stainless steel construction for superior durability and corrosion resistance
