Tetra Pak is launching Onestep technology, a Tetra Lactenso Aseptic solution that incorporates UHT white milk production within a single, high-throughput process.

Onestep technology eliminates the need for pasteurisation, pre-treatment and intermediate storage.

In one unbroken step, raw milk is preheated, clarified, separated, standardised and homogenised, before undergoing UHT treatment and regenerative cooling, and then being transferred to two aseptic buffer tanks.

This shortens processing time from as much as two days to just a few hours, cutting operating costs by up to 50 per cent compared with conventional solutions.

Onestep technology combines heat treatment, separation and standardisation into a single step, simplifying and accelerating the production process.

In addition to shortening the time it takes to process raw milk, Onestep technology also incorporates aseptic buffering, enabling completely automated and continuous UHT operations, with fewer process steps and smaller hold-up volumes in the line.

Tetra Pak Onestep technology can reduce energy and water consumption by up to 35 per cent, and cut waste and effluent load by as much as 60 per cent, thanks to accurate chemical use during cleaning in place (CIP).

These savings are estimated to reduce the carbon footprint of the production process by around 40 per cent.

Furthermore, the streamlined process cuts product loss by up to 30 per cent compared to conventional UHT solutions, with fewer process steps and smaller hold-up volumes in the line.

With the ability to change the fat content of milk products without stopping production – and to run milk with different fat contents at the same time – Onestep technology provides aseptic line flexibility, enabling efficient production planning and high utilisation of filling machines – with up to 100 per cent availability.
