Alfa Laval\u2019s new electrical system slashes dairy pasteurization cleaning time and water use<\/h1>\/ in Product news<\/a> <\/span><\/span><\/header>\n<\/div><\/section>
\n

Alfa Laval has introduced a new technology that significantly reduces biofilm formation in dairy pasteurization equipment, enabling processors to extend cleaning intervals while reducing water, chemical and energy consumption. The Extend system, which can be retrofitted to existing heat exchangers, uses low-voltage electrical current to inhibit bacterial growth on equipment surfaces.<\/h3>\n

<\/p>\n

Technical innovation in biofilm prevention<\/h3>\n

The system works by transmitting a weak electrical current through the heat exchanger, achieving a 90-99% reduction in biofilm formation. This technological advancement allows dairy processors to safely extend the time between cleaning in place (CIP) operations from the industry standard of eight hours to 12 hours or more, whilst maintaining food safety standards.<\/p>\n<\/div><\/section>

Field-proven performance data<\/h3>\n

In a year-long implementation at a major Scandinavian dairy facility operating two 70,000-litre-per-hour pasteurization lines, the Extend\u2122 system demonstrated significant operational benefits.
\nThe installation achieved:
\n\u2022 50% increase in operational uptime
\n\u2022 30% reduction in cleaning intervals
\n\u2022 7,000 m\u00b3 reduction in water consumption
\n\u2022 100,000 kWh energy savings
\n\u2022 35-tonne reduction in cleaning chemical usage<\/p>\n

System specifications and compatibility<\/h3>\n

The compact device, measuring 15×6 cm and weighing 350g, is designed for seamless integration into existing dairy processing systems.<\/p>\n

Key technical features include:
\n\u2022 Operating temperature range: -40\u00b0C to 105\u00b0C
\n\u2022 Chemical resistance to standard CIP solutions
\n\u2022 CE, RoHS, and Reach compliance
\n\u2022 Universal compatibility with heat exchangers regardless of manufacturer<\/p>\n

Installation and implementation<\/h3>\n

The system\u2019s plug-and-play design allows for installation without production downtime, offering flexibility through three size options to accommodate various heat exchanger configurations. This adaptability makes it particularly suitable for dairy processors looking to upgrade existing pasteurization equipment.<\/p>\n

Environmental impact<\/h3>\n

As the dairy industry faces increasing pressure to reduce its environmental footprint, the technology addresses several key sustainability challenges. The significant reductions in water, energy, and chemical usage align with industry efforts to meet stricter environmental regulations while maintaining operational efficiency.<\/p>\n

Quality assurance and monitoring<\/h3>\n

According to Anna Andrys, Strategic Project Manager at Alfa Laval, the implementation process includes comprehensive monitoring: \u201cWe closely monitored every aspect of the installation together and eagerly awaited the real-life results. It\u2019s undoubtedly been a shared success.\u201d<\/p>\n

Industry context<\/h3>\n

The development comes at a crucial time for the dairy industry, which is actively seeking solutions to reduce its environmental impact while maintaining production efficiency. The technology represents a practical approach to achieving sustainability goals without compromising processing capabilities or food safety standards.<\/p>\n
