Danfoss Drives

Danfoss DrivesIt operates as an independent unit or within automated lines. Main advantages are:    Extremely low consumption of energy needed for baking. For freely-baked bread also below 200 kWh/t of bread.  Significant heat energy savings achieved via – Insulation to reduce heat loss, including high-quality insulated return part and glazed windows state of the art burners – automatic regulation of conveyor traction in the baking zone  Potential additional energy savings, including – automatic vapor flow – compatible recuperators for flue gases and vapor    Electrical energy savings via the optimization of heating valves A frequency converter-driven centrifugal fan for flue gases. The frequency converter ensures better power transmission efficiency and, above all, essentially reduces maintenance needs and prolongs the oven lifetime. Direct drive with planetary reduction gear Independent temperature regulation in the baking area. Technological vapor is brought into the baking area. The quantity of vapor is regulated by means of manual valves or the automatic regulation of vapor flow.

The graph shows reduction of CO2 footprint in total, when using a Gostol cyclotermic tunnel baking oven type TPN to bake bread or other products, by comparison with an older traditional oven. The graph data is based on these baking conditions: – Cyclothermic tunnel baking oven 3.75 m wide and 30 m long – Long loaf, weight 500 g – Production 24 hours/day, 300 days/year – Gas price 0.04 EUR/kWh – Electricity price 0.05 EUR/kWh  Reduction in CO2 due to electrical energy.37,944 kg/year  Reduction in CO2 due to recuperation .25,308 kg/year  Reduction in CO2 due to steam .26,973 kg/year  Reduction in CO2 due to gas.226,884 kg/year Total reduction in CO2 .317,109 kg/year 2 Danfoss VLT Drives · DKDD.PC.705.A1.02Page 1Page 3
