GEA offers a range of steam stretching machines for batch production that can improve yields by up to 1% when compared with hot water systems.

GEA has worked with the industry to develop a range of batch steam stretching machines available with either dipping arms, or with rotary shafts. Our systems can process very soft mozzarellas and drier, pizza-type cheeses, at production capacities ranging from 200 kg/h to 1,000 kg/h. All our stretching machines canbe connected to any of the GEA range of drum molding, molding units or special molding machines.
The curd cheese is heated using steam that is injected directly into the lower half of the cylindrical mixing vat through multiple automatic pneumatic needle valves. The chamber features a hot water jacket to facilitate precise temperature control of the curd, and a feeler gauge continually monitors and displays the cheese temperature.
GEA machines are built for reliable, robust performance. Our steam stretching solutions are constructed with servo-motor drives to guarantee accurate speed control of the dipping arms or rotary shafts, and electrical motor-reducers to ensure constant speed of the cylindrical chamber.
GEA machines are constructed using stainless steel AISI 304, with Teflon coating on augers, mixing arms and the machine body. We can also supply units treated using GEA’s innovative Vulcan technology, which offers a near-permanent alternative to Teflon.
All GEA steam stretching technology has been developed to offer optimum hygienic design that complies with the most stringent regulations. Certain units can be supplied with cleaning pipes and sprinklers for connection to an external cleaning-in-place plant, which reduces water usage, and minimizes down time. Mechanical and electromechanical protection on dangerous areas ensures operator safety, and remote assistance by GEA engineers is also possible for PLC-operated units.
GEA’s past fiscal year was one of significant growth and further profitability gains. In particular, the technology group substantially increased order intake, with all divisions contributing here. GEA also made progress in all Mission 30 strategic growth areas. In addition, GEA met key interim targets under its climate plan ahead of schedule. Major milestones in fiscal year 2025 were admission to the DAX index, the award of one of the largest contracts in the company’s history, and streamlining of the corporate structure.
Thanks to a new SmartParc manufacturing site, food processors in the U.K. are cutting their running costs and emissions. With GEA heating and cooling technology at its core, this collaborative production model demonstrates how innovation is accelerating the industry’s net-zero ambitions.
“Brewing eggs is like brewing beer.” It’s the kind of comparison that makes you smile – and then it clicks: Something complex suddenly feels simple. Through this personal film, set in the agricultural heartland of the U.S., we explore precision fermentation and the real-world work it takes to turn an idea into food.
