DENMARK – Lyras, a Danish company specializing in sustainable pasteurization technology, has unveiled the world’s largest unit for UV treatment of liquid foods, named the Raslysation Castor.

The technology, developed in collaboration with Novozymes, a leading biotech group known for its industrial enzymes, is set to revolutionize the treatment of opaque liquids while prioritizing environmental conservation.

The Raslysation Castor is capable of producing a staggering 380,000 litres per hour, which is ten times the output of Lyras’s previous flagship product, the Raslysation Sirius.

What sets this innovative unit apart is its ability to inactivate bacteria and other microorganisms in liquids like whey and juice through raslysation, preserving the product’s taste and structure while saving a significant amount of resources.

Traditionally, pasteurization equipment consumes copious amounts of water and energy.

Raslysation, on the other hand, offers a more efficient alternative, conserving between 60% to 80% of water and 60% to 90% of the energy, resulting in substantial cost savings and reduced environmental impact.

Notably, a dairy equipped with a single Lyras plant can reduce its annual CO2 emissions by approximately 850 tons, equivalent to 164 trips around the world in an average family car.

“The Raslysation Castor allows us to ensure that food producers who process 100 cubic meters of liquid per hour can easily inactivate all microorganisms,” Nete Zarp Nielsen, CTO of Lyras said.

“This technology has opened up new global opportunities for us, and we are set to expand further within the next 12 months.”

He added that Lyras’s global footprint has been steadily growing due to the international demand for its water-saving pasteurization and raslysation technology.

“The company now has branches in the Netherlands, France, Spain, and South Africa, in addition to its home base in Denmark,” he said.

Mark Kalhøj Andersen, CCO at Lyras, shared the company’s ambitious vision highlighting the goal at Lyras for the food and processing industry to have saved at least one million tonnes of CO2 by the end of the decade.

“To achieve this, we must expand across multiple markets. The next step for us is to break into the United States,” he stated.

“Raslysation, besides its environmental benefits, offers higher product yields and maintains stringent microbial control while reducing operating costs.”

The valuable proteins in raw materials are preserved in their original form, as heating is not required.

This technology ensures high food quality in opaque liquids, such as dairy products, through the use of ultraviolet light and unique hydraulics that effectively inactivate microorganisms.

When applied to replace depth filtration, it results in a higher yield and greater automation in the production process.
