A highly improved unit operating on diesel or Gas (Propane or Natural Gas) and designed to supply a rationally and properly distributed heat for the production of an excellent quality Pita Bread. Equipped with a feeding unit conveying automatically the leavened dough sheets from the final proofer into the baking chamber of the oven. The perfect thermal insulation of the body prevents any heat loss, resulting a remarkable gas saving. The external body is entirely covered with Stainless Steel plates, giving the unit a distinguished appearance. The machine is mechanically simplified, permitting easy operation and minimizing the need of maintenance. Frame Assembly: -Made by painted steel frame and covered with Stainless Steel 1 mm thickness sheets. Conveyer assembly: -The tunnel combustion chamber made by Heat Resistant refractory bricks or Stainless steel S309 specially designed for baking thin and thick bread and completely isolated by high density Rock-Wool sheets. -All mechanical parts, such as: chain-sprockets-bearings are from the external side to insure a complete isolation for the dough pieces . -The parts subjected to direct flame are made by 6 mm Heat Resistant Stainless Steel (S309). -Heat resistant Stainless Steel conveyer chain for long life trouble free operation. -Heat resistant Stainless Steel (S309) conveyer plates for high quality bread and long life trouble free operation -Production speed controlled by mean of frequency inverter. Burner: -High quality diffusion flame burner working on Gas that compliance with safety and health regulations with respect to ISO and FDA Norms. Thermal Power: from 180 to 400 Kw. -Optionally: Electronically modulated burner where the fan and the fuel pump are equipped with inverter.
