Homogenizers in the Dairy Industry: Applications, Machines & Spare Parts

Homogenization is one of the most critical processing steps in the modern dairy industry. Without it, the fat globules in milk would rise to the surface, creating an unappetizing cream layer. At BOS Homogenisers, we have spent decades supporting dairy processors worldwide with high-quality spare parts and expert service for all major homogenizer brands.

Why Homogenization Is Essential in Dairy Processing

Raw milk contains fat globules ranging from 1 to 10 micrometres in diameter. During homogenization, these are broken down to approximately 0.2 to 2 micrometres. Benefits include extended shelf life, better digestibility, improved texture and consistency, and enhanced flavour release.

Dairy Applications That Rely on Homogenization

Drinking Milk

Standard pasteurised and UHT milk undergoes homogenization at pressures typically between 150 and 250 bar.

Cream and Whipping Cream

Dairy processors typically operate at lower pressures of 50 to 100 bar for cream applications, often using two-stage homogenization.

Yogurt and Fermented Products

Homogenization of base milk at 150 to 200 bar is essential for achieving smooth, creamy texture and reducing syneresis.

Cheese

Homogenized milk produces softer, more spreadable cheese with improved fat retention.

Ice Cream Mix

Ice cream base mix is typically homogenized at 140 to 200 bar in a two-stage process.

Equipment Used in Dairy Homogenization

Major brands include APV (SPX FLOW) Rannie and Gaulin series, GEA Niro Soavi Ariete series, Gaulin, and Tetra Pak. All share the same fundamental working principle. See our machines overview page.

Common Wear Parts in Dairy Homogenizers

Valve seats and valve balls (replace every 1,000 to 3,000 hours), piston seals and packings, pistons and plungers, compression rings and O-rings. We supply spare parts for all major dairy homogenizer brands.
