Processing Systems for Milk Powder
Process milk powders with equipment designed for homogeneous blending, controlled agglomeration and reliable powder handling. Depending on the formulation and end use, processing requirements can include consistent ingredient distribution, improved wettability and dispersibility, reduced dust formation and suitable flow properties for downstream dosing and packaging.
Hosokawa Micron supplies mixing equipment and agglomeration systems for processing spray-dried milk powders and dairy powder blends. Our technologies can be supplied as individual machines or integrated into powder processing systems, with configurations selected according to the material properties, required product characteristics and production capacity.
Processing challenges in milk powder applications
Milk powder formulations vary in fat content, particle size, bulk density and surface properties. These differences influence how powders mix, flow and disperse in water, as well as their behaviour during storage, transfer and packaging.
Typical processing requirements include:
- homogeneous blending of milk powders with other dry ingredients
- controlled liquid addition where required by the formulation
- improved wettability and dispersibility for instant applications
- reduced fines and dust formation
- consistent particle size and bulk density
- accessible equipment for inspection and cleaning
The appropriate processing sequence depends on the required end product. Some applications need dry blending only, while others benefit from agglomeration followed by drying, cooling and size classification.
Mixing and blending of milk powders
Milk powder blends require consistent distribution of ingredients while maintaining the physical properties of the powders. Mixer selection depends on the formulation, required mixing intensity, batch size and production cycle.
Nauta conical screw mixer
The Nauta® conical screw mixer by Hosokawa Micron provides gentle, low-shear batch blending of milk powders and other dairy ingredients. Its controlled powder movement supports homogeneous mixing with low energy input to the product.
The mixer can be configured with hygienic product-contact surfaces, inspection access and cleaning provisions suited to the application.
Vitomix ribbon screw mixer
The Vitomix ribbon screw mixer by Hosokawa Micron combines rapid powder circulation with adjustable mixing intensity. It supports efficient blending of dairy powder formulations where short mixing times and production capacity influence equipment selection.
For formulations requiring liquid addition, the Vitomix can distribute liquids into the moving powder bed. The required operating conditions depend on the liquid properties, addition rate and target powder characteristics.

Agglomeration for instant milk powder applications
Fine milk powders can be difficult to wet and disperse in water, particularly when their surface properties limit contact with the liquid. Agglomeration enlarges the particles into a more open structure, helping improve reconstitution behaviour and reduce dust.
The Flexomix mixing and agglomeration system by Hosokawa Micron combines powder feeding with controlled liquid or steam addition. For suitable milk powder formulations, this process forms agglomerates whose properties can be adjusted through the binder selection, addition rate and operating conditions.
Where appropriate for the formulation, lecithin addition can help improve the wettability of fat-containing milk powders. Trials establish the suitable combination of powder, binder and process settings.
After wet agglomeration, fluid bed drying and cooling remove the added moisture and condition the product. Subsequent sieving separates the required particle size fraction.
Integrated milk powder processing systems
An agglomeration installation brings together powder handling, dosing, binder addition, agglomeration, drying, cooling and classification. These operations must be coordinated to achieve the required particle properties and consistent production performance.
Hosokawa Micron can configure integrated systems around the material characteristics, required capacity and available installation space. Mixing installations can also be combined with feeding, weighing, controlled discharge and downstream powder handling.
Equipment access and the cleaning strategy are considered during system design, alongside the process requirements.
