Homogenizers

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.

Why Choose a High-Pressure Homogenizer?

Homogenizers deliver precise and repeatable particle size reduction, helping manufacturers improve product quality while maintaining efficient production.

Key benefits include:

Consistent particle and droplet size
Stable emulsions and suspensions
Improved product texture and mouthfeel
Enhanced product appearance
Increased shelf life
Better ingredient dispersion
Repeatable processing results
Hygienic design for food and pharmaceutical production
Suitable for laboratory, pilot and full-scale manufacturing

Applications of Homogenizers

High-pressure homogenizers are used wherever products require consistent particle size, stable emulsions or improved dispersion.

Dairy & Food Processing

Homogenizers are widely used for:

Milk
Cream
Yoghurt
Ice cream
Sauces
Dressings
Beverages
Plant-based drinks

They improve texture, prevent phase separation and enhance product stability.

Pharmaceutical & Biotechnology:

Vaccine production
Drug suspensions
Lipid emulsions
Cell disruption
Protein extraction
Nanoparticle production

High-pressure homogenization provides repeatable processing while maintaining product quality.

Cosmetics & Personal Care:

Creams
Lotions
Serums
Shampoos
Cosmetic emulsions

Homogenization creates smooth, stable formulations with a consistent appearance.

Chemical Processing:

Pigment dispersions
Resins
Adhesives
Coatings
Fine chemical emulsions

The process improves dispersion and product uniformity.

How to Choose the Right Homogenizer

Selecting the correct homogenizer depends on both the product characteristics and the production requirements.

Key considerations include:

Processing capacity
Operating pressure
Required particle size
Product viscosity
Temperature
Number of homogenization stages
Hygienic design requirements
CIP/SIP capability
Future production scalability

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.
