Key specifications

Flows Up To 45000 l/h
Pressure Up To 1500 bar

Product features

Ultra-high-pressure capability: The Rannie range operates at pressures up to 1,500 bar, supporting demanding homogenization and cell-disruption processes.
High production capacity: Models are available with capacities up to 45,000 l/h, covering industrial-scale continuous processing requirements.
Application-specific configuration: Three- and five-piston arrangements, different piston geometries and multiple valve types allow the homogenizer to be specified around the actual process duty.
Robust valve materials: Ball and poppet valves can be specified in tungsten carbide, Stellite or ceramic to match process conditions and wear requirements.
Single- or two-stage homogenization: Rannie units can be configured for one- or two-stage operation according to the required product characteristics and homogenization duty.
Energy-saving option: The optional APV MicroGap homogenizing valve can reduce energy consumption by achieving the required homogenization effect at lower pressure; AxFlow states potential energy-cost savings of up to 25% compared with conventional valves.
Hygienic process assurance: Listed certifications include 3-A, ATEX, CE, EC 1935/2004, FDA and ISO 9001, supporting specification across hygienic and regulated production environments.
Lifecycle support: AxFlow provides manufacturer-authorized APV maintenance and repair capability together with stocked OEM spare parts, supporting long-term equipment availability.

Product description

Info

APV Rannie Homogenizers are specified for continuous processes requiring stable emulsification, dispersion or high-pressure treatment. Applications include dairy products, beverages, sauces, cosmetics and pharmaceutical products, with broader use across food, confectionery, chemical, detergent, pigment and emulsion production. Homogenization forces the liquid through a restricted valve gap, converting pressure into turbulent flow that breaks down particles or droplets and distributes them more uniformly. The resulting process can improve mixture stability, texture, viscosity consistency and product quality.

The Rannie range is constructed around three- or five-piston homogenizer configurations and a three-piece cylinder block. Different piston geometries and ball or poppet valve arrangements can be specified according to the application, with valve materials including tungsten carbide, Stellite and ceramic. Homogenizing pressure can be adjusted manually or hydraulically depending on the model and application. Units can also be constructed for either single- or two-stage homogenization.

Operational capability extends to 45,000 l/h and 1,500 bar, although individual model limits vary substantially across the series. AxFlow lists configurations ranging from Rannie 5 through larger production machines, with motor groupings extending from 5 kW to 315 kW. High-pressure capability makes the range suitable not only for conventional emulsification and dispersion but also for cell disruption. Optional MicroGap homogenizing valve technology can reduce the pressure required to achieve a specified homogenization result, lowering energy demand in suitable duties.

Correct specification requires the product properties, required particle or droplet reduction, capacity, operating pressure, homogenization stages and valve configuration to be verified against the individual process. Replacement requirements should additionally confirm the exact Rannie model, piston arrangement, installed valve technology and drive configuration rather than relying on nominal capacity alone. AxFlow provides APV equipment selection, manufacturer-authorized maintenance and repair, and access to OEM spare parts. This combination supports continued performance while reducing lifecycle risk for installed Rannie equipment.

Where are APV Rannie Homogenizers used?

APV Rannie Homogenizers are used for dairy products, beverages, sauces, cosmetics and pharmaceuticals, as well as wider food, chemical and industrial processing. Their high-pressure capability supports conventional emulsification and dispersion duties and more demanding processes such as cell disruption.

What materials are available for critical Rannie valve components?

AxFlow specifies tungsten carbide, Stellite and ceramic as available materials for Rannie ball and poppet valves. The appropriate valve arrangement and material should be selected according to the processed medium, required pressure and application conditions. The source does not provide a complete material specification for every wetted component across all Rannie models.

What failure risks should be considered with a high-pressure homogenizer?

Wear of high-pressure components and deviations from the specified treatment conditions can affect homogenization consistency, process reliability and product quality. AxFlow notes that even small process deviations in hygienically sensitive homogenizer applications can create product inconsistencies, microbiological risks or batch losses. Correct equipment specification and planned maintenance are therefore important to sustained operation.

How is the correct APV Rannie model selected?

Selection should be verified against required capacity, homogenizing pressure, product properties, valve arrangement, piston configuration and whether single- or two-stage homogenization is required. Individual models have different pressure and capacity limits; for example, the overall series reaches 45,000 l/h and 1,500 bar, but those maxima do not apply simultaneously to every model.

What should be considered when maintaining or replacing an APV Rannie Homogenizer?

Maintenance should focus on preserving the condition and verified specification of components exposed to high-pressure operation, particularly the homogenizing and pump valve systems. For replacement, the existing model, duty, pressure, capacity, piston arrangement and homogenization stages should be confirmed before equipment is specified.
