High-Efficiency High-Pressure Homogenizers for Mid-Scale Plants
GEA introduces the compact KOB series, offering cost-effective 400-bar performance, hygienic CIP/SIP execution, and modular automation for versatile processing.

GEA has launched its new KOB homogenizer series—encompassing models 11, 22, 45, and 90—to provide small and medium-sized production plants with access to industrial-grade performance at an optimized investment level. Capable of reaching operating pressures up to 400 bar, this versatile line is engineered for a wide array of food, beverage, chemical, and personal care applications, including the challenging task of feeding spray dryers. By delivering a compact, hygienic, and highly flexible platform, the series ensures that mid-scale processors can smoothly integrate these units into their modern digital supply chain to optimize production logistics and asset utilization.
Compact Engineering and Reduced Operational Overhead
The KOB series is specifically designed for processors requiring dependable, fit-for-purpose homogenization within a limited physical footprint. Its compact architecture is enabled by an optimized crankcase and gear-reducer design that yields high mechanical efficiency while generating minimal heat, noise, and vibration. Because the drive compartment requires neither external oil cooling nor forced-air ventilation, the system relies on fewer auxiliary components. This significantly lowers installation complexity, maintenance requirements, and utility costs.
At its mechanical core, the robust high-pressure design guarantees stable performance even when processing moderately viscous or abrasive formulations. Key engineering features include:
- Poppet-Type Pumping Valves: Enhanced flow characteristics and feeding stability that substantially reduce noise and cavitation while maximizing volumetric efficiency.
- Flexible Valve Configurations: High-efficiency homogenizing valve options tailored to specific product characteristics.
- Tailored Material Selection: Competitively priced, wear-resistant base parts for standard applications, with optional ultra-wear-resistant materials available to extend component service life in abrasive environments.
Sanitary Compliance and Advanced Process Automation
Engineered to fulfill strict sanitary regulations, every model in the KOB family is capable of complete Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) cycles, with configurations available to meet stringent 3-A sanitary standards. For aseptic product handling, the machines feature steamable full-stroke barrier chambers that eliminate contamination risks.
To support varying levels of plant digitalization, the KOB series offers a modular automation architecture ranging from basic motor-starter solutions to comprehensive PLC/HMI controls. The system can be equipped with a second-stage pressure gauge and advanced pressure transmitters across both homogenization stages and the outlet. This instrumentation enables seamless connectivity with SCADA and plant-wide automation systems. This end-to-end data integration provides real-time operational telemetry akin to an automotive data ecosystem, where continuous sensor diagnostics are aggregated to optimize downstream processing efficiency and prevent unplanned downtime.

In the global industrial homogenization market, the GEA KOB series competes directly with mid-capacity high-pressure units from manufacturers such as SPX FLOW (APV series), Tetra Pak, and Alfa Laval. Competitor platforms in this pressure class frequently depend on external, auxiliary cooling loops for the crankcase oil, which increases both the physical footprint and the mechanical failure points of the skid. GEA differentiates the KOB series by optimizing internal gear geometries to eliminate forced utilities entirely in this power bracket. Furthermore, while many entry-level competitors utilize standard ball valves that struggle with flow consistency at 400 bar, GEA's implementation of poppet-type valves provides superior seating dynamics, reducing pressure upstream fluctuations and protecting downstream spray drying nozzles from pressure spikes.
From a fluid dynamics perspective, maintaining high volumetric efficiency at 400 bar requires minimizing internal backflow and tolerances within the compression block. The KOB series achieves this through precision-machined plungers and specialized high-pressure packing geometries that minimize friction-induced thermal degradation.
By avoiding the necessity of a forced-air ventilation subsystem, the enclosed frame reduces ambient acoustic emissions to levels significantly below traditional industrial homogenizers. This makes it an ideal drop-in replacement for legacy machinery in older facilities where floor space is constrained and strict occupational noise limits apply. The modularity of the automation interface also ensures that legacy analog plant architectures can interface with the homogenizer without requiring a complete control-room overhaul.
