Dusseldorf (Germany)/Lichfield (New Zealand), December 7, 2016 - After a two-year construction period and initial commissioning in September, Fonterra inaugurated its state-of-the-art, high-efficiency milk powder factory at Lichfield, New Zealand. The expansion included a new milk powder processing plant, services, wastewater plant and distribution center. The centerpiece of the facility is the largest milk powder spray dryer currently available on the market, which was built by GEA. In terms of material usage, energy consumption and waste, the milk processing plant is now the most efficient facility of its kind in the industry.
GEA constructed the milk powder plant as a turnkey solution, providing all the process technology - from reception of the milk tanker and evaporation, to drying, powder handling and packaging. The drying chamber weighs around 200 tons and has a diameter of 18 meters. The processing capacity of 30 tons of high-quality milk powder per hour equates to over 4.4 million liters of milk a day. This corresponds to the volume of almost two Olympic-standard swimming pools. The spray dryer is the second of its kind built by GEA. Its sister plant Darfield II, which is also operated by Fonterra in New Zealand, has been producing high-quality powdered milk reliably since December 2013. For Lichfield, the GEA experts developed several innovations to improve sustainability and further reduce the total cost of ownership to the customer. In particular, energy efficiency was a key focus for the project team. For instance, the plant requires very little process water as the evaporator condensate is filtered in a specific way and, thanks to GEA technology, can then be re-used during processing. As a result, Fonterra has reduced its demand for ground water for the site.
