Tetra Pak launches OneStep technology for processing aseptic white milk

Monday 31 May 2010

New technology shortens UHT milk processing time by up to 90 per cent, cuts operating costs by up to 50 per cent

Tetra Pak today launches 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.

In essence, the innovation of OneStep technology is that it combines heat treatment, separation and standardisation into a single step, significantly 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.
