Niehoffs Kaffeerösterei

Niehoffs Kaffeerösterei (Lebensbaum group) also installed a new coffee roaster equipped with a coffee pre-heating system (recirculating exhaust gases). Thanks to the improved efficiency of the new roaster and the reduced energy use due to the preheating system the total energy consumption of coffee roasting was reduced by about 29% and the natural gas consumption of coffee roasting decreased by about 55%. The improved energy efficiency due only to the preheating system is insteads in the range of 8-10%. The new roaster uses about 0.45 kWh of total energy per kg of coffee roasted.
