Dairies face growing pressure to provide more nutrition while using less energy, water and raw material. Yet many plants still optimize individual machines rather than the process as a whole. At the IDF World Dairy Summit 2026 in Auckland, New Zealand (November 15–20, 2026), GEA will show how technologies from dairy farming to aseptic transport can work together along the Better Dairy Journey (booth 11–12). At a technical symposium, Dr. Riccardo Bergamini will outline how dairies can prioritize investments to reduce plant emissions.
Why the dryer matters in New Zealand
RaboResearch identifies New Zealand as the world’s largest single-country dairy exporter, with an estimated 22% share of global dairy exports in 2025 and 53% of global whole milk powder exports. USDA analysis indicates that the country’s product mix is gradually shifting toward cheese, milk fats, infant formula and specialty protein ingredients. For processors, more product variants can mean additional changeovers, cleaning cycles and quality checks. Spray drying also remains one of the most energy-intensive stages of milk powder production.
The losses happen at the interfaces
Plants lose energy as unrecovered heat, product through deviations from specification and production time when residues remain after cleaning. GEA therefore considers the chain as a whole, from milking on the farm through milk reception and processing to drying, packaging, utilities and service.
“Many plants measure efficiency machine by machine. But the losses happen in between: between farm and factory, between the dryer and the energy supply,” says Thorsten Heidack, Senior Vice President Nutrition Plant Engineering Execution APAC at GEA. “If you plan the dryer, heat recovery and cleaning together from day one, you find savings that no single machine would show you.”
“Digital tools help us close these gaps while the plant is running,” Heidack adds. “With GEA OptiPartner®, we actively control the plant and bring in our process know-how. When raw materials or ambient conditions change, the software adjusts the setpoints – on the spray dryer as well as on the chillers and heat pumps that supply cooling and heat. That way, we increase output and reduce energy consumption at the same time.”
Technologies along the Better Dairy Journey
The journey begins on the farm, continues through processing and drying, and extends beyond the factory through aseptic transport.
Resource-efficient milking on the farm: Resource efficiency starts before the milk reaches the dairy. The GEA DairyRobot R9500 milking robot was among the first solutions to receive GEA’s TÜV-validated Add Better label, based on its electricity savings. In independent testing, it used up to a third less electricity and around 13% less water than its predecessor. Because the robot milks each quarter individually, it also reduces milk losses: if one quarter shows elevated conductivity, only that quarter’s milk is diverted, while the milk from the other three still goes into the vat. The Coubrough family in Tīrau, New Zealand, benefits from this on its pasture-based farm, where two DairyRobot R9500 units milk the herd.

A filling and emptying station connects to a reusable ISO tank container holding up to 20,000 liters. The container can travel by road, rail and sea and serve as temporary storage. A patented concept maintains overpressure with sterile gas throughout the journey to help prevent recontamination. In a full-scale trial, UHT milk traveled from Japan to Singapore.
RaboResearch reports that New Zealand has been China’s leading supplier of imported liquid milk and cream since 2024. For export-oriented producers, the system could help manage seasonal peaks, reach distant markets or supply contract manufacturers.
The DLG (German Agricultural Society) awarded two of its five International FoodTec Award 2027 gold medals to GEA technologies: the Mobile Aseptic Solution and GEA AddCool®. AddCool® integrates a high-temperature heat pump into spray dryers, recovers process waste heat and feeds it back into the dryer at up to 130 °C while also providing ice-water-grade cooling. At Arla Foods’ site in Svenstrup, Denmark, the system cuts natural gas consumption for heating the main drying air by 59%. The jury cited an annual CO₂ reduction of around 1,500 metric tons, depending on the share of renewable electricity. The GEA Ariete Homogenizer 2.0, which combines energy-saving homogenizing valves with the NiSoMate® analyzer, received a silver medal. The award ceremony takes place on February 23, 2027, at Anuga FoodTec in Cologne.
