The Tetra Pak® Indirect UHT unit DE is a processing unit for highly efficient, continuous ultra-high temperature treatment of dairy products. The unit is of aseptic design, and a tubular or plate heat exchanger is used for fully indirect heating to obtain a product that can be stored at ambient temperatures. It is available as a stand-alone unit or as part of a complete line solution.
Maximized operational efficiency thanks to running times of up to 40 hours and minimized energy consumption
Minimized product losses thanks to the low-loss balance tank function
Consistent product quality through quick heating and cooling – with guaranteed performance
The unit is fully automated to safeguard aseptic status during production, operating in four steps: pre-sterilization, production, intermediate cleaning (IC) and cleaning-in-place (CIP). The product is regeneratively pre-heated in a Tetra Pak tubular or plate heat exchanger, homogenized, indirectly heated by a hot water circuit, held in a holding tube for the required time and then regeneratively cooled to packaging temperature. A closed pre-sterilization loop enables a quick start-up, and if there is a time gap between pre-sterilization and production, hibernation mode saves up to 85% of extra energy during water circulation.
Applications: Dairy products such as milk, flavoured milk, cream, yoghurt drinks, buffalo milk and formulated dairy products, as well as other low acid products like plant-based dairy alternatives. Combinations with non-dairy applications such as juice, tea and coffee are also possible.
Capacity: variable, from 1,000 l/h up to 40,000 l/h.
Options: Siemens or Rockwell PLC control, Eco heating protein denaturation holding tube, hibernation mode, aseptic homogenization, deaerator, internal CIP system, IntelliCIP 2.0 and more.
