Tetra Pak OneStep technology for milk production from powder

Tetra Pak has extended the application of its OneStep processing technology to milk production from powder. Producers can now prepare UHT milk from powder in one continuous step, reducing operational cost by up to 40% and cutting carbon impact by more than half, according to the company.

The technology removes the multiple steps of pasteurisation and intermediate storage in the traditional process of preparing milk from powder before UHT treatment. After a complete redesign using the Tetra Pak High-Shear Mixer and Tetra Alfast in-line blending unit, the process is now streamlined into one continuous step: skim milk powder is mixed with preheated water to make a concentrate, which is then blended with the precise amount of water and fat before undergoing UHT treatment.

Enabling complete automation and continuous operations, the technology reduces milk waste traditionally lost between processing steps and improving consistency in product quality.

The milk production technology can be used to produce one single product or configured into multiple streams to produce a number of recipes, giving users flexibility in production. It can also be used to produce formulated milk, which combines liquid milk or powder with fat and flavour to create flavoured and value-added milk or lactic acid drinks.
