Tetra Lactenso Aseptic with OneStep technology

The Tetra Lactenso Aseptic with OneStep technology incorporates UHT white milk production within a single process.

Tetra Pak claims OneStep technology eliminates the need for pasteurisation pretreatment and intermediate storage of raw milk. 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. The company says this can shorten processing time to a few hours.

In essence, the OneStep technology combines heat treatment, separation and standardisation into one step, which simplifies and may accelerate the production process.

The line includes several pieces of equipment. The Tetra Therm Aseptic Flex is a UHT unit that integrates heat treatment with separation and standardisation. The Tetra Spiraflo is a tubular heat exchanger with good energy recovery. It incorporates the Floating Protection System, a thermal-stress-absorbing design.

The line also includes a Tetra Centri AirTight Eco, a hermetic direct-driven separator. An integrated unit for milk and cream standardisation, the Tetra Alfast prevents fat content deviation in the final product. The Tetra Alex homogeniser achieves the same product quality at lower pressure than conventional homogenising devices, Tetra Pak claims.

Also included in the system are the Tetra FlexDox, Alcip and PlantMaster.
