MILKING THE BENEFITS OF ADVANCED TECHNOLOGY
With the dairy industry struggling with the impact of the energy crisis, Ruben
Andreas Riksted, marketing manager at Lyras, examines how advanced technology can help producers become more sustainable and energy efficient

ndustries across the UK and Europe are being impacted by the energy crisis, and food production
is no exception to this. The energy crunch has caused production costs to skyrocket, even leading to the closure of some dairies and food processors. The European Milk Board has called on the EU
to implement measures for the dairy and food production sectors, including introducing energy price caps for dairy farms, milk processors and other stakeholders in the dairy production chain and food production sector. Many dairy farmers still cannot cope with the explosion in energy costs, but a key overlooked reason for that is simply because their production processes are out of date. Institutional changes are needed – and advancements in technology are the answer.
AUTOMATION The world of technology and automation has become increasingly helpful across numerous industries in recent years. When it comes to dairy processing, automation has played a massive role in improving sustainability and cutting energy costs. The use of quality automation programs and the implementation of new technology can be highly beneficial among dairy processors when used correctly. Across industries in general, the rise of
automation and technology in production lines has created a myriad of benefits. Automated processes maintain product quality and consistency, removing the element of human error that can lead to inconsistency in product appearance, taste and other factors. When it comes to the food industry especially, even minor deviations from expected standards in quality can lead to a product being rejected by customers. Automation plays a key role in the move to sustainability as well. Optimising processes and
reducing waste are key components of the drive for more sustainable production. However, due to the rising energy costs, it’s finally time for dairy productions to address whether their process of operations is really as energy-efficient as it could be. When utilised effectively, processors can achieve their sustainability goals, but as it stands financially, companies may not be able to survive the mounting automation costs.
PASTEURISATION A tried and tested method to purify milk products, pasteurisation is a critical pillar of the dairy production sector. The process has existed for hundreds of years and, over time, manufacturers have continued to streamline the process to improve product quality and reduce waste for increased production capacity. Pasteurisation involves killing any harmful bacteria
by heating milk to approximately 72°C for at least 15 seconds, ensuring that it is safe to drink whilst also prolonging its shelf-life. The process needs to be efficient enough to reliably kill any harmful microbes in milk without affecting the taste or nutritional value of the milk. But eventually, like with all technology and
processes, as time goes on tried and tested processes become outdated and overtaken by up-and-coming technologies. Pasteurisation, especially in the current energy crisis, has become an inefficient production
method in comparison to the rise of its newer technology counterparts. Dairy processing lines cannot afford to maintain the high demands of energy needed to rapidly heat and cool products over and over.

EXPLORING THE ALTERNATIVES While it may be easier for companies to stick with the technology and processes that they already know, it is important to explore alternative avenues in order to bypass the stresses of the energy climate entirely. Within the food and drink industry, process
energy reduction and adopting more optimised processes can be a struggle. Processes such as pasteurisation often lack sufficient monitoring to track energy consumption, and so realising there is a need to cut down drastically on energy use may be a step taken far too late. Dairy producers at every level must take steps
toward more sustainable practices and move away from those with high energy demands. Thankfully, well-tested green technologies are available and are ready to take over from legacy equipment and practices that have existed for so long. It’s just a matter of companies choosing to take the first steps towards adopting these exciting innovations to reduce their carbon footprint and advance their energy efficiencies – and it has never been a better time to do so.
