TetraPak showcases Tetra Lactenso Aseptic with OneStep technology, a practice line that incorporates UHT white milk production within a single, high-throughput process. This technology eliminates the need for pasteurisation pre-treatment and intermediate storage of raw milk. In one unbroken step, raw milk is preheated, clarified, separated, standardised and homogenised before undergoing UHT treatment and regenerative cooling. It is then transferred to two aseptic buffer tanks. This shortens processing time from as much as two days to just a few hours. In essence, the innovation of OneStep technology is that it combines heat treatment, separation and standardisation into a single step, which simplifies and accelerates the production process. In addition to shortening the time it takes to process raw milk, technology also incorporates aseptic buffering. This enables completely automated and continuous UHT operations, with fewer process steps and smaller hold-up volumes in the line.
