Homogenizers are used to reduce variations in two heterogeneous substances, make them uniformly consistent and to reduce separation after mixing.

Why buy homogenisers from AxFlow
APV homogenisers bring a steady repeatability to a process that can be depended upon. With the APV product portfolio, SPX Flow offer a wide range of homogenisers covering laboratory applications, pilot plant machines through to large scale production homogenisers. Their Rannie and Gaulin brands have been synonymous with homogenisation for 100 years - are relied upon by the world's leading manufacturers across the Dairy, Food & Beverage, Pharmaceutical, Healthcare, chemical and the Biotech sectors.
How do homogenisers work
A high-pressure homogenizer uses a positive displacement piston pump to force product through a specially designed homogenizing valve at high pressure. As the product passes through the narrow valve gap, it is subjected to intense shear, turbulence, cavitation and impact forces that break droplets and particles into much smaller, more uniform sizes.
The result is a stable product with improved emulsion quality, reduced particle size and enhanced consistency. Depending on the application, homogenizers may operate in single-stage or two-stage configurations to optimise particle size distribution and product stability.
The Rannie and Gaulin technologies offer a large selection of features, build options, materials and multiple homogenising valve technologies. Combined this with extensive experience across all industries, and SPX Flow has the ability to deliver customised homogenisers specific to the customer's application. All APV homogenisers are 3A approved, comply with EN1935:2004 and are CE marked. If required, they can be supplied with FDA approved packing.

AxFlow's engineers evaluate the complete process to recommend the most appropriate homogenizer, ensuring optimum product quality, efficient operation and long-term reliability.
Frequently Asked Questions
What is a homogenizer?
A homogenizer is a machine that uses high pressure to reduce particle and droplet size, producing stable emulsions, suspensions and dispersions.
What is homogenization?
Homogenization is the process of creating a uniform product by reducing particle or droplet size, improving stability, consistency and product quality.
What industries use homogenizers?
Homogenizers are widely used in the food and beverage, dairy, pharmaceutical, biotechnology, cosmetics and chemical industries.
What is the difference between a homogenizer and a mixer?
A mixer combines ingredients, while a homogenizer reduces particle size under high pressure to create finer, more stable emulsions and suspensions.
AxFlow offer APV homogenizers, including laboratory, pilotplant, and production models made to meet the most specialized emulsion and dispersion applications.

FAQ Homogenizers
How does homogenizing pressure affect particle size and product stability?
Higher homogenizing pressure generally increases the energy applied to the product, which can reduce particle or droplet size and improve dispersion. However, the optimum pressure depends on the formulation, desired particle-size distribution, temperature sensitivity and number of passes. More pressure is not always better if it increases heat load or unnecessary energy consumption.
How does product temperature affect homogenizer performance?
Temperature influences viscosity, pressure drop, valve behaviour and the energy required to homogenize the product. Warmer products may flow more easily, while excessive temperature can affect sensitive ingredients or accelerate product degradation. The homogenizer should therefore be assessed across the full process temperature range.
How do I choose the correct homogenizing valve design?
Valve geometry affects shear, impact, cavitation and the resulting particle-size distribution. The best design depends on whether the objective is emulsification, dispersion, cell disruption or another process duty. AxFlow’s APV Rannie and Gaulin ranges offer multiple homogenizing valve technologies so the valve can be matched to the application.
What causes excessive wear in a high-pressure homogenizer?
Wear can be accelerated by abrasive particles, unsuitable valve materials, excessive operating pressure, poor lubrication, cavitation damage or contaminated product. Monitoring valve condition, seals and pressure stability can help identify deterioration before it affects product quality or causes unplanned downtime.
How does homogenization affect downstream heat treatment or filling?
Homogenization can change viscosity, particle size, emulsion stability and heat-transfer behaviour. Those changes can influence pressure drop, heating or cooling performance and filling consistency, so the homogenizer should be considered as part of the wider process rather than as an isolated machine.
