Lyras uses a UV-driven raslysation system to replace the more traditional heat treatment way of eliminating bacteria
CLIMATE- FRIENDLY DAIRY
A new technology promises to signifi cantly cut water processing emissions in dairy farms
D
airy farms spend a lot of time and energy ensuring that microorganisms are deactivated as part of
their water processing activity – the traditional way of doing has been via heat treatment. A new technology from Danish sustainable pasteurisation technolpogy company Lyras, uses a UV-driven raslysation system to replace the more traditional heat treatment way of eliminating bacteria, The company claims that its system provides microbial control while bringing energy savings and reducing a dairy farm’s CO2 emissions..

INACTIVATION OF MICROORGANISMS Food business operators such as dairies have various requirements for the quality of the water they use in their processes. Usually, they have separate water sources and analyse the quality of these as part of their own quality assurance. Since water is often an integral part of food production - used to empty tanks and vats for curd grain, when fl ushing product from process pipes as well as for processing water in cheese production - it must be completely
clean. Raslysation eff ectively inactivates all micro-organisms in water and can therefore often fully replace the traditional heat treatment of both water and product. The company claims that its pasteurisation replacement also removes all risks of glass contamination since it is constructed in such a way that there is no direct contact between the treated liquid, water, and the ultraviolet lamps, while a log 12 reduction is achieved on microorganisms in water.
