Product: Tetra Lactenso Aseptic with OneStep technology

Tetra Pak showed its Tetra Lactenso Aseptic with OneStep technology, a best-practice line that incorporates UHT white milk production within a single, high-throughput process.

OneStep technology eliminates the need for pasteurization pre-treatment and intermediate storage of raw milk. In one unbroken step, raw milk is preheated, clarified, separated, standardized and homogenized 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; cutting operating costs by up to 50% compared with conventional solutions.

In essence, the innovation of OneStep technology is that it combines heat treatment, separation and standardization into a single step, which significantly simplifies and accelerates the production process.

In addition to shortening the time it takes to process raw milk, OneStep 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.

Tetra Lactenso Aseptic with OneStep technology can reduce energy consumption by more than 40%, reduce effluent load by up to 40% and cut water consumption by as much as 60%. These savings are estimated to reduce the carbon footprint of the production process by around 40%. Furthermore, the streamlined process cuts product loss by up to 33% compared to conventional UHT solutions.

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 outstanding aseptic line flexibility, enabling efficient production planning and high utilization of filling machines with up to 100% availability.
