Direct Fire Tunnel Oven
Industrial Tunnel Ovens for Bakeries
Since 1957, POLKA Ltd. has defined the gold standard for industrial tunnel ovens. We don't just build ovens; we help the world’s leading bakeries perfect the art of pita and flatbread production. With over 65 years of engineering refinement, our gas-powered tunnel technology delivers unmatched consistency and quality, backed by a global commitment to superior customer support.
Direct Fire vs. Indirect Fired Tunnel Ovens
Unlike indirect systems that rely on heat exchangers, a direct fire tunnel oven places the heat source, typically high-efficiency ribbon burners, directly inside the baking chamber. This configuration offers three distinct advantages:
-
Near 100% Thermal Efficiency: By eliminating the "middleman" of a heat exchanger, fuel-to-heat conversion is maximized, significantly reducing operational utility costs.
-
Rapid Heat-Up & Recovery: Direct fire ovens reach target temperatures faster than any other system, making them ideal for high-volume lines with frequent product changeovers.
-
Radiant & Conductive Harmony: Our ovens utilize a combination of radiant heat (from the flame) and conductive heat (from the belt or stone hearth) to create the "flash heat" necessary for superior dough spring.

Key Benefits of Direct Fire Tunnel Ovens
High-Temperature Performance
Direct flame allows for extremely high baking temperatures, reducing dwell time and increasing hourly output.
Precise Color and Texture Control
Multi-zone design with independent burners ensures consistent browning and surface finish across every unit.
Energy Efficiency at Scale
With no heat exchanger and fast heat transfer, direct fire systems reduce thermal lag and improve overall baking efficiency in continuous operations.
Modular, Scalable Design
Tunnel sections can be extended to increase capacity as production grows, protecting your capital investment.
Production Reliability
Industrial-grade burners, belt systems, and control architecture minimize downtime in 24/7 environments.
Products That Benefit Most from Direct Fire Baking
Flatbreads: Pita, Naan, Lavash, Tortillas, Focaccia
High heat creates rapid expansion, signature blistering, and consistent coloration.
Pizza and Par-Baked Bases: Delivers strong bottom bake and fast top browning, ideal for frozen or par-baked pizza production.
Crackers and Baked Snacks: Direct fire provides rapid surface dehydration and crisp texture in early baking stages.
Rolls, Bagels, and High-Heat Bread Products: Supports high-output lines that require aggressive baking without sacrificing internal structure.
