Tetra Therm® Aseptic VTIS
Tetra Pak® UHT treatment
Tetra Therm® Aseptic VTIS
The Tetra Therm® Aseptic VTIS is an aseptic processing unit for the continuous direct UHT treatment of heat-sensitive, low-acid products. Steam is injected straight into the product, which reaches UHT temperature almost instantly, so milk, cream, soymilk, ice-cream mix and dairy desserts keep their natural taste and colour. The unit also handles smooth soups, sauces and starch-based products, including products with small particles.
Low overall heat load that protects taste, colour and nutritional value
Suitable for a wide range of dairy and plant-based products
Product losses below 150 litres per 15,000-litre run with the double balance tank system
In the steam injector, the product is heated from 80 °C to UHT temperature and the steam condenses in about 0.1 seconds. The short, intense heat treatment inactivates microorganisms and spores while low fouling keeps cleaning simple. The product is then flash-cooled in a vacuum vessel with a built-in condenser, whose large conical top limits carry-over and flavour loss. Protective panels around the Tetra Pak® Tubular Heat Exchanger save up to 6% energy, or up to 11% with additional insulation, and a floating protection system lets the tubes expand freely to reduce the risk of cracks and loss of sterility.
Applications: Milk, enriched milk, cream, soymilk, formulated dairy products, ice-cream mix, ESL products, dairy desserts, non-dairy cream and smooth soups and sauces.
Capacity: 2,000 to 30,000 l/h, with a variable capacity ratio of 1:2 as standard.
Options: Steam infusion as a gentler alternative for whipping cream and stabilized products (4–8% higher operating cost than injection), and a combined heating solution that switches between direct (VTIS), indirect (Flex) and combined (Plus) heating, as a combi model or an upgrade.
- Steam injection with flash-cooling
- Double balance tank system
- Floating protection system for the heat exchanger
- aseptic design
- direct UHT
- 2,000–30,000 l/h
Built for long runs: The double balance tank system keeps product and water in separate tanks for a sharp interface during changeovers, and the automatic homogenizer damper with automatic air refill and fully automated CIP prevents vibration and cavitation that would shorten production.
With its gentle direct heating and high operating efficiency, the Tetra Therm® Aseptic VTIS is a proven solution for premium, shelf-stable dairy and plant-based products. Contact us today to learn more.
