SAIMAI ‘s new type tunnel oven is a direct heated oven for industrial bakeries. The required heat is created directly in the baking tunnel by means of modulating ribbon gas burners. The construction of the baking tunnel, divided into modules, guarantees an even heat transfer to the product.
In order to directly transfer heat to the products, direct gas fired ovens use ribbon burners that are placed above and below conveyor belts, the flames created by each burner then radiate energy into the baking chamber, heating the air and the products.
Integrated PLC Control System;
Baking chamber width | 1050mm-3200mm |
Baking chamber length | To be customized |
Baking conveyors | Slat band plate, Mesh wire conveyor, Steel band |
Conveyor load capacity | Up to 40Kg/m2 |
Baking time control | Ratio up to 1:10 |
Modular design | Pre-assembled, fully insulated, pre-wired |
Heat resource | NG,LPG |
Features:
Air supply system | Each zone is equipped with an independent air supply system. |
Gas supply system
| Each zone is equipped with an independent gas supply system and equipped with the dual electromagnetic slow-opening valves can prevent the sudden connection of the gas |
Exhausting system | It is equipped with two sets of exhaust dampers respectively at upper and lower of each zone, Each exhaust fan is equipped with independent inverter, and the exhaust volume can be adjusted in real time. |
Ignition system
| It is automatically controlled by the burning program controller, and each burning pipe can be selected and turned on/off from the touch screen, Flame detection ensures gas is cut off when there is no flame in the combustion system. |
Temp Control system
| Three temperature probes are set for the upper fire in each temperature zone, another three temperature probes are set for the bottom fire, and the average value of the three temperature measurement points is taken as the reference temperature, to reduce the measurement error and improve the temperature control accuracy. |
Control system | The core control system is Rockwell PLC, and the distributed IO control method is used to realize regional modular control. The main control module is used to control the overall operation of the system; each zone is equipped with independent temperature control modules to achieve precise control; The whole oven is equipped with multiple safety monitoring systems to ensure the safety and stability of equipment operation. |
