Direct Gas-Fired Ovens
In these ovens, the product and the band are directly heated by the pipe burners installed over and under the band. Mainly used for baking hard biscuits, crackers, pies (puffs), pretzels, and pizza dough.
The air preheated in a separate combustion chamber is circulated in the heating furnace (convection) to bake food products. Mainly used for baking soft biscuits (cookies).
Indirect Radiant Ovens
Air preheated in a separate combustion chamber is continually recirculated through air pipes mounted in the heating furnace, as biscuits are baked by radiant heating. Mainly used for baking soft biscuits (cookies) and hardtack biscuits.
