The Farhat Infrared Tunnel Oven is a continuous bakery oven that uses infrared emitters or radiant-heating surfaces to transfer energy directly toward the product. Oven selection begins with the product and heat-transfer requirement—not with an unsupported promise that one technology is always faster or more efficient.
For flatbread, pizza and pita, the bake may last only seconds or minutes, yet it must develop structure, color and moisture consistently across the band. Farhat therefore engineers the baking surface, top and bottom heat, zones, belt speed, burner or emitter control and exhaust around the target product.
How the baking process works
- Products enter on a conveyor selected for the bake and temperature range.
- Infrared energy heats exposed product surfaces while conduction and internal moisture movement complete the bake.
- Zoned emitter output and belt speed establish the time-temperature profile.
- Exhaust removes released moisture and combustion products where applicable.
Product temperature, evaporation and expansion change throughout the oven. Zone settings and exhaust should be treated as a coordinated recipe: increasing temperature alone may darken the surface without producing the required pocket, base structure or final moisture.
Suitable products
The infrared tunnel oven can be evaluated for:
- flatbread and pizza formats validated on the system
- rapid-bake products
- products requiring strong radiant input
- multi-product portfolios when the heater and band configuration support them
Farhat should run or review thermal trials when a new product differs materially in thickness, hydration, topping load, surface flour or required bake time. One oven can support several SKUs, but the useful operating window must be demonstrated for each.
Process controls
- zone power or burner modulation
- top/bottom energy balance
- belt speed and residence time
- product and exhaust temperature
- flame supervision and safety interlocks where gas is used
Gas-fired models require a compliant gas train, purge sequence, ignition control, flame supervision, pressure switches, emergency shutdown and plant ventilation designed for the installation country. Electrical models require the corresponding load, protection and safe isolation. Final compliance scope belongs in the quotation and local approval process.
Reference configuration and technical data
Final dimensions, capacity, utilities, materials and control scope are configured for the approved product and project. Farhat should issue a model-specific technical data sheet with every quotation.
How to select the oven configuration
- electric versus gas infrared source
- product absorptivity, thickness and moisture
- direct exposure versus heated-surface design
- required color profile and bake time
- utility cost, exhaust and maintenance capability
Farhat also needs the product loading map, upstream proofing discharge, acceptable color variation, cooling destination and available exhaust route. A heat-and-mass balance helps size the oven and cooling section from actual product load.
Oven integration, hygiene and maintenance
The oven should exchange ready, run, fault and speed signals with infeed and discharge equipment. Mechanical layout must provide safe burner or heater access, band tracking and tensioning, inspection doors, crumb removal, hood and duct access, and clearance for maintenance. Cleaning methods must be compatible with insulation, hot-zone materials, burners, sensors and the selected baking band.
Preventive maintenance should cover the drive, band or chain, bearings, burners or emitters, flame-safety devices, temperature sensors, exhaust system, seals and insulation condition. Only trained personnel should adjust combustion or safety parameters.
Request a thermal and layout review
Send Farhat the product range, target output, plant utilities and available layout. The oven team can recommend a heating configuration and define the data required for trials and acceptance testing.
