Tetra Pak Launches New Ultra-Efficient UHT Unit
The unit gently treats heat-sensitive products such as milk, enriched milk, cream, ice cream mixes, other dairy desserts and soy milk products whilst cutting operating costs by 15% compared to the previous generation of direct UHT systems.
Nov 1 2010 --- Tetra Pak has announced the launch of its new Tetra Therm Aseptic VTIS, a direct heating unit for UHT dairy production which incorporates innovative design to deliver significant efficiencies. Thanks to instantaneous heating and cooling, Tetra Paks direct UHT technology minimises thermal impact on the product, thus enabling premium quality.
The unit gently treats heat-sensitive products such as milk, enriched milk, cream, ice cream mixes, other dairy desserts and soy milk products whilst cutting operating costs by 15% compared to the previous generation of direct UHT systems.
The new Tetra Therm Aseptic VTIS unit:
• Cuts products losses by up to 40% compared to current industry standards
• Boosts running time up to 60 hours
• Reduces heat load to minimise impact on properties such as taste and colour
• Offers the highest operational efficiency of any direct UHT system on the market
Tetra Pak focuses its innovation on developing more effective and efficient solutions. It means our customers can maximise production whilst cutting waste and costs. In developing the new Tetra Therm Aseptic VTIS unit, we have explored every stage and examined every component to deliver better ways of processing heat-sensitive premium dairy products, said David Pomeroy, Food Category Director.
Tetra Therm Aseptic VTIS introduces a range of design innovations to drive efficiencies:
• A new double balance tank system, with one tank for product and one for water, making it possible to completely empty the main balance tank of water before filling it with product, reducing losses in the mix phase.
• A unique flash cooling system combines a new conically topped vessel and built-in spray condenser, rather than a conventional external condenser, to reduce product carry-over during cooling to 0.01%. The new chamber design, with easier access for inspection, maintenance and service, helps ensure uncompromising food safety.
• The preheating now enables product/product regeneration, using the heat-treated product, rather than hot water, to transfer heat to the cool inlet product. This reduces steam consumption by 5% compared to previous models and provides significant cost savings over time.
• An improved steam injector and holding cell design prevents hotspots and minimises fouling in the system. This enables longer running times up to 60 hours between cleanings compared to 30 hours with previous generation units. Savings on cleaning and pre-sterilisation reduce production cost per unit.
Tetra Therm Aseptic VTIS solutions can also be configured to match each customers specifications for one or more individual products, as well as production requirements for highly versatile and efficient product-optimised operation.
Tetra Therm Aseptic VTIS is available as a separate unit or as part of a Tetra Lactenso Aseptic dairy production solution, with guaranteed performance on key indicators such as running time, energy consumption, product losses, cleaning times, pre-sterilisation time and more.
