Denmark-headquartered biotech group Novozymes has invested in a brand new and energy-friendly filtration substitute from Danish Lyras. 

The group has bought its first UV system primarily based on the raslysation know-how for inactivation of microorganisms. Raslysation goes to enhance work setting and cut back power consumption for the worldwide market chief in industrial enzymes.

Novozymes’ new raslysation system from Lyras goes to exchange labor-intensive filtration processes that beforehand triggered bodily pressure on the corporate’s workers in reference to guide dealing with of filters. On the similar time, the funding is predicted to supply elevated security close to undesirable microbiology and decreased power consumption.

Lyras and raslysation

Lyras has developed raslysation know-how, which inactivates microorganisms in drinks and different opaque liquids by the use of UV gentle. The approach is much much less energy-intensive in comparison with conventional pasteurization and filtration strategies. Consequently, raslysation saves between 60 and 90% of the power, and 60 to 80% of the water conventional pasteurization requires. If, for example, a dairy that produces 40 tonnes of whey per hour, had been to modify from conventional pasteurization to raslysation, it might, primarily based on the EU common, emit 519 tonnes of CO2 much less per 12 months. 

Raslysation makes use of a UV gentle supply mixed with a lightweight filter that concentrates a particular kind of UV gentle. The liquid is directed previous the sunshine supply in a managed motion in order that the whole liquid is illuminated. This system successfully inactivates micro organism. On the similar time, extra of the pure style, nutritional vitamins and proteins are preserved. The approach might be utilized to a spread of liquid meals and fluids.

The phrase raslysation

Lyras’ know-how for inactivating microorganisms with UV gentle as an alternative of energy-intensive heating has beforehand been referred to as “chilly pasteurization.” Nevertheless, because the phrases chilly and pasteurization are contradictory, the know-how was given a reputation of its personal—raslysation. The phrase is created from the primary three letters of inventor of the know-how, Rasmus Mortensen’s title, and the Danish phrase for gentle.

“As a number of enzymes can not face up to excessive temperatures, immediately we use traditional depth-filtration to take away the bioburden in our merchandise. For that motive, our workers change heavy units of filter plates each day as a part of the purification course of for the completed enzyme focus. Raslysation relieves us from this process. Concurrently, we achieve much more management of undesirable microbial exercise in our processes. We additionally anticipate to see a distinction in our power invoice. All issues thought of, raslysation matches into Novozymes’ inexperienced technique in each method,” stated Steen Skaerbaek, senior director at Novozymes. 

“As soon as the UV know-how offers the anticipated outcomes at Novozymes’ location in Kalundborg, the subsequent logistical step will likely be to put in Lyras’ UV know-how at a number of of our world strategic websites, that produce high-value enzymes and proteins for the meals trade.”

Main by instance

“You must give huge, acknowledged corporations like Novozymes props for main by instance and integrating new and inexperienced applied sciences. Novozymes has been a unbelievable accomplice within the strategy of testing and designing the optimum answer. We’re proud that collectively we now have created the idea for a system that an organization with Novozymes’ excessive degree of analysis would need to put money into and use globally in future,” stated Lyras CTO Nete Zarp Nielsen.

Microbial management over 45,000 liters per hour 

Novozymes’ new raslysation system will be capable to deal with 45,000 liters of business enzyme liquid per hour. Raslysation can be used as an alternative choice to pasteurization of meals similar to brine, whey, juice, iced tea, and lots of different liquids.
