与间接加热方式相比,GEA 直接蒸汽喷射 UHT 设备旨在为产品提供极低的热负荷。这种低热负荷有助于防止蛋白质 - 例如牛奶中的乳清蛋白质 - 维生素和其他成分变性或降解,从而更好地保留营养价值。较低的热影响也能更好地保留产品的色泽和风味,使其口感更加新鲜。
直接蒸汽喷射系统结合闪蒸冷却技术,通过蒸汽在产品中直接凝结实现 快速加热,而非间接加热。快速加热和冷却可进一步保留乳制品的原始鲜味。
蒸汽直接喷射到产品中,随着蒸汽凝结,其热量被传递给产品,使产品几乎瞬间被均匀加热至 140-150°C,并在该温度下保持 2-4 秒。加热后,产品在真空室中通过闪蒸快速冷却,从而去除冷凝蒸汽。
直接喷射和直接注入蒸汽 UHT 工艺的区别在于蒸汽引入产品的方式,这会影响产品质量以及设备设计。两种方法均能有效实现快速 UHT 处理,因此选择哪种方法取决于产品需求。
特征和优势
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.
