GEA KOB high-pressure homogeniser series

The GEA KOB series of homogenisers is designed for small and medium production plants. With KOB models 11, 22, 45 and 90 available, the homogenisers offer a compact, hygienic and flexible solution for a broad range of food, beverage, chemical and personal care applications, including homogenising and feeding spray dryers. Features include: optimised and compact mechanical construction, lower noise levels, simplified maintenance access and efficient power use.

At the core of the homogenisers is a robust high‑pressure design up to 400 bar, supporting stable and efficient homogenisation for demanding, moderately viscous and abrasive applications. To meet the requirements of diverse applications, higher‑efficiency homogenising valve technology and more wear‑resistant materials are available as options to the economical version.

The series is designed for processors who need adequate and fit-for-purpose homogenisation performance within a limited footprint. Its compact architecture is enabled by an optimised crankcase and gear-reducer design that delivers high mechanical efficiency while generating minimal heat, noise and vibration. As the drive compartment requires neither oil cooling nor forced-air ventilation, the machines are designed to rely on fewer auxiliary components and deliver lower installation, maintenance, energy and utility demands.

Designed to meet demanding sanitary requirements, 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 homogenisation stages as well as the outlet, for process automation and control. This makes the series suitable for a broad range of products and processes such as milk, dairy ingredients, beverages, plant-based formulations and selected chemical, personal care and cosmetic products in manual, semi-auto and fully automated production lines.

The series supports a wide range of automation levels, from simple motor-starter solutions to full PLC/HMI control.
