Avantages
Efficacité optimale
La Tetra Pak® Unité de traitement UHT indirect assure un traitement hautement efficace et continu des produits laitiers à ultra-haute température. L’unité présente une conception aseptique et est dotée d’un échangeur thermique tubulaire ou à plaques pour le chauffage indirect afin d’obtenir un produit pouvant être stocké à température ambiante.
Données clés

Capacité
1 000 - 40 000 l/h
Applications
La Tetra Pak Unité de traitement UHT indirect convient aux produits laitiers, comme le lait, le lait aromatisé, la crème, les yaourts à boire, le lait de bufflonne, les produits laitiers formulés ainsi que d’autres produits à faible acidité comme le lait de soja. Des combinaisons avec des applications non laitières, telles que les jus, le thé et le café sont également possibles.
High efficiency, low operating cost
- Best scope of supply and low total cost of ownership enabled by efficiencies and reduced utility consumption throughout the entire production cycle
- Low energy consumption during pre-sterilisation, enabled by a closed pre-sterilization loop
- Hibernation mode – reducing steam and energy consumption by 60% during water circulation.
- Fouling control and smart cleaning solutions increase production time, resulting in operational cost savings
- Integrated operations enabled with automation – providing a full production overview
Caractéristiques
Product-to-product regeneration
Reduced steam and cooling medium need
Direct product-to-product regeneration enables low steam consumption (only 20 kg/1000 kg of product) and makes 92% heat recovery possible. Additional energy is saved by achieving an outlet temperature that is ~15 °C above the inlet temperature. This means a drastic reduction in the cooling medium required.
Fouling control
Longer running time to save money
Fouling is minimized so the equipment can run for up to 40 hours with good quality white milk, meaning a lower cost for every litre produced. This is achieved by optimizing the set-up with a temperature-controlled, protein denaturation holding tube, accurately controlling both ΔT and pressure drop, and controlling the flow in the hot water circuits.
Bottom-filling balance tank
Lower product losses
The balance tank features a special bottom-filling design and a sharp border between mixing phases. It can save up to 75 litres of milk* at every product change (at 15,000 L/h), compared to the traditional filling of a flat-bottom balance tank. The inlet valve arrangement shortens the mixing phase, and a frequency-controlled pump further reduces energy consumption.
*Calculation is based on comparing Low loss balance tank and Tetra Therm Aseptic Flex headerbatch solution. Production scenario: 15,000 L/h capacity,3 product changes/day,300 production days/year
IntelliCIP™ 2.0
Cleaning adapted to need
Thanks to IntelliCIP™ 2.0, a new technology (patent pending WO2013092414), cleaning results can be monitored in-line with the help of CIP sensors. This means cleaning settings can be optimized depending on the degree of fouling, resulting in more uptime and a reduction in utilities consumption.
Automatic damper
For longer running times
Homogenizer dampers absorb pressure variation and shocks before and after the homogenizer. Automatic air refill maintains the air cushion in the homogenizer damper to ensure smooth operation. Without the air cushion, vibration and cavitation would occur and shorten the running time. Fully automated CIP is included - increasing operator safety, improving hygiene, and further optimizing the production cycle.
Hibernation
Spend less getting ready
If there is a time gap between pre-sterilisation and production, the unit can be set to automatically enter into hibernation mode. This optional function reduces the amount of energy and cooling water during sterile water circulation by up to 60% compared to traditional water circulation – without losing the aseptic status of the plant.
Heat exchanger protective panels
Great energy savings potential
Protective panels built around the Tetra Pak® Tubular Heat Exchanger encapsulate the equipment and contain the heat. This gives up to 6% savings on energy consumption compared to heat exchangers without panels. With added insulation, savings can increase to 11%. The panels also increase operator safety since they reduce the risk of contact with hot surfaces.
Heat exchanger floating protection system
Longer lifetime and exceptional efficiency
Aseptic product in the inner tubes of the Tetra Pak® Tubular Heat Exchanger flows at a higher pressure than the untreated product on the shell side. A floating protection system allows for thermal expansion, greatly reducing the risk of damage from cracking, and consequent loss of sterility. In addition to extending lifetime, this improves food safety.
