Eficácia potente
A Tetra Pak® Unidade UHT indireta é uma unidade de processamento para o tratamento de temperatura ultra-alta altamente eficiente e contínuo de produtos lácteos. A unidade tem design asséptico e é usado um trocador de calor a placas ou tubular no aquecimento indireto para a obtenção de um produto que possa ser armazenado em temperaturas ambiente.
Resumo
Tratamento térmico UHT contínuo para produtos alimentares líquidos sob condições assépticas
Capacidade
1.000 – 40.000 l/h
Aplicações
A Tetra Pak Unidade UHT indireta é adequada para produtos lácteos, como leite, leite aromatizado, nata, bebidas de iogurte, leite de búfala e produtos lácteos formulados, bem como outros produtos de baixa acidez, como soja e leite de soja. Combinações com aplicações não lácteas, como leite, chá e café, também são possíveis.
Product-to-product regeneration
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
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
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.

IntelliCIP™ 2.0
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
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
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
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
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.
