Tetra Therm® Aseptic Flex
Indirect UHT treatment

Application
Tetra Therm® Aseptic Flex is a top-of-the-line processing unit
for high-performance continuous indirect UHT treatment. The
unit uses a tubular or plate heat exchanger under aseptic conditions to obtain a product that can be stored at ambient temperatures. Tetra Therm Aseptic Flex is suitable for dairy products such as milk, flavoured milk, cream, yoghurt drinks,
buffalo milk and formulated dairy products, as well as for other
applications such as juice, soy milk, tea and coffee.
Tetra Therm Aseptic Flex is available as a stand-alone unit or
as part of a complete line solution.

Working principle
The module is fully automated to safeguard aseptic status
while in production. The operation is divided into four steps:
•t Pre-sterilization
•t Production
•t AIC (aseptic intermediate cleaning)
•t CIP (cleaning-in-place)
Before production can start, it is necessary to sterilize the
aseptic area by circulating pressurized hot water. In the tubular version, the aseptic part is equipped with an internal sterilization loop to minimize energy consumption and start-up
time. After sterilization, the unit is cooled to production temperature. Finally, sterile water is circulated through the production unit.
