GEA launches new KOB high pressure homogenizer series for small and medium-scale production

GEA has developed its KOB series, a new cost-efficient line of homogenizers reaching up to 400 bar. The series is designed to give small and medium production plants access to industrial-grade performance at an attractive investment level. With KOB models 11, 22, 45 and 90 available, the homogenizers offer a compact, hygienic and flexible solution for a broad range of food and beverage applications, including homogenizing and feeding spray dryers. Optimised and compact mechanical construction, lower noise levels, simplified maintenance access and efficient power use are key aspects of this line, according to the company..

They offer a high‑pressure design up to 400 bar, for demanding, moderately viscous and abrasive applications. To meet the requirements of diverse applications, higher‑efficiency homogenizing valve technology and more wear‑resistant materials are available as options. The base configuration uses wear-resistant parts, providing an economical choice for standard, non-abrasive products, while optional high-wear-resistant materials extend service life in more demanding, abrasive formulations.

Its compact architecture is enabled by an optimized crankcase and gear-reducer design that delivers mechanical efficiency while generating minimal heat, noise and vibration. As the drive compartment requires neither oil cooling nor forced-air ventilation, the machines rely on fewer auxiliary components and deliver lower installation, maintenance, energy and utility demands. The use of poppet-type pumping valves enhances flow characteristics and feeding stability, reducing noise and cavitation while improving volumetric efficiency and extending component life.

Every KOB model is available with CIP and SIP capabilities and can be configured to meet 3-A sanitary standards. Steamable full-stroke barrier chambers provide aseptic product handling. The machines can be equipped with a second-stage pressure gauge and pressure transmitters on both homogenization stages as well as the outlet, for process automation and control.

The KOB series supports a wide range of automation levels, from simple motor-starter solutions to full PLC/HMI control. Connectivity options enable seamless integration into SCADA and plant-wide automation systems, allowing processors to choose the right level of digitalisation for their operation.
