Leaner and more sustainable production of yoghurt

From raw milk to formulated yoghurt milk in one go

Best-practice line for yoghurt milk with OneStep technology

One single heat treatment and minimum to no intermediate storage – with the Line for yoghurt milk with OneStep technology, the non-value adding parts of the process are removed and the step from raw milk to formulated yoghurt milk happens in one go.

OneStep technology combines separation, standardization, blending, heat treatment, and more in a single step. There’s no faster or more efficient way to produce yoghurt milk. You can start from raw milk or milk powder, or a combination of both. OneStep technology makes yoghurt milk production more energy-efficient, reducing emissions and saving resources.

The line for yoghurt milk with OneStep technology comes in two patent pending configurations, differentiated in the way that ingredients are added to the yoghurt milk;

in-line addition of powder
in-line addition of slurry

Reducing TCO

Compared to conventional lines, both configurations of the Best-practice line for yoghurt milk with OneStep technology saves you money. The installations are smaller and more space-efficient, and reduce your consumption of water, steam, electricity and cleaning detergents. The solutions also produce less waste.

Reduced carbon footprint

The Best-practice line for yoghurt milk with OneStep technology minimize the use of resources – and as the consumption of electricity and steam is low, your carbon footprint becomes smaller in comparison to using conventional solutions.

Carbon footprint (kg CO2 equivalents)*:
Conventional line: 21.8
In-line powder addition: 16.3
In-line slurry addition: 16.6

Zero compromises on product quality

A leaner process, less equipment – so how is it possible to maintain the product quality from the conventional process?

First of all, the Tetra Pak High Shear Mixer ensures optimal performance of the added powder. Furthermore, you get the right composition of yoghurt milk by securing accurate fat content and ingredient addition to the fermentation tank.

And last but not least, the Tetra Pak Pasteurizer D controls it all and makes sure the temperature stays correct all throughout the process.

An innovation that can be customized

Your needs are what matters – we always configure the line to fit your targets, recipes, capacity and product range. You can also make yours a multi-purpose line, where you can produce a variety of dairy products on these compact processing lines.

Line configurations

Best-practice line In-line powder addition

The heart and soul of this configuration is the integrated high shear vacuum mixer, which disperses the powders in the liquid while minimizing air incorporation. The step from raw milk to formulated yoghurt milk happens in one go with only one heat treatment and no intermediate storage.

In-line slurry addition

With this configuration, the yoghurt milk is formulated by in-line addition of an ingredient slurry at the standardization point after separation. The concentrated slurry is prepared by a high shear mixer. You go from raw milk to formulated yoghurt in one go, with only one heat treatment and limited intermediate storage.
