About the company
The future of liquid foods – Bringing pasteurization to the 21’st century
Lyras present a novel patented technology, cold pasteurization. Cold pasteurization removes all the drawbacks of conventional pasteurization while eradicating bacteria and reducing energy consumption by more than 90%.

Our technology provides the following advantages:

Energy efficient:

Currently, around 25% of the total energy consumption within dairies originates from the pasteurization and centrifugation processes.
Lyras’ cold pasteurization technology replaces conventional pasteurization and centrifugation equipment and thereby decreases energy consumption by more than 90% for HTST pasteurization. In the case of UHT pasteurization, the energy required is almost doubled, resulting in even greater energy savings.

Higher quality:

Cold pasteurization adds only a miniscule amount of energy directly into the raw milk, compared to conventional pasteurization. Cold pasteurization is thereby a much gentler treatment as the raw milk is only exposed 0,02% of the energy compared to conventionally pasteurized raw milk. The milk is treated in only a few seconds and thereby retains its natural taste and composition to a much greater degree.

Healthy:

As the milk stays chilled while undergoing treatment for a few seconds, the nutritional values are retained, as vitamins and proteins are preserved to a higher degree.
Today, especially in cheese production, different preservatives are added to extend product shelf life. Cold pasteurization brings the potential to reduce and possibly eliminate the need for these added preservatives.

Extend shelf life:

Cold pasteurization achieves a higher reduction in bacteria than conventional HTST pasteurization. Replacing the HTST treatment with our cold pasteurization solution, the bacteria removed equals 99.9999%, including the removal of heat-resistant spores and bacteria. This brings the opportunity for milk to be stored for even longer periods than possible today.

No fossil fuels:

Conventional pasteurization equipment requires a vast amount of energy to both warm up, retain the high temperature and cool down the milk. These processes are to a large extent dependent on energy stemming from natural gas. By eliminating the heating- and cooling process, and relying only on electricity, cold pasteurization can be solely driven by sustainable energy.

No waste in production:

Cold pasteurization is one simple continuous process to treat both spores and bacteria within the raw milk. Today, this requires multiple processes where both milk and water are wasted. Cold pasteurization treats the milk in one closed system, where no milk is wasted to extrude spores, and less water is required as Lyras’ system has reduced cleaning requirements.
Achieving a higher reduction of bacteria within the milk gives dairies greater control of the bacterial culture within the processed milk. This has a big influence on the subsequent processing of the milk. For instance, in cheese production, a higher reduction in bacteria increases the dairies control of the cheeses’ bacterial culture, thereby decreasing the rate of failed batches.

Pasteurization made simple :

The surrounding infrastructure complexity of Lyras’ cold pasteurization system is significantly lower and takes up less space than conventional equipment. This size reduction is so significant that it will eliminate the need for expansion in many dairies dealing with space constraints. Cold pasteurization not only eliminates the pasteurization process, but also the need for centrifugation, currently required to eliminate spores.
Cold pasteurization is superior in its processing capabilities, as it has a decreased process time and a significantly higher uptime. This is possible, as our cold pasteurization system provides a continuous flow, is easy to implement in a “plug and play” fashion and compatible with standard CIP (Clean-in-place) cleaning procedures.

Cold pasteurization – for everyone:

The capabilities of cold pasteurization sets greater standards for public health and safety. Today, people in many parts of the world do not have access to safe properly treated milk. This leads to a range of diseases caused by insufficient food hygiene.
Cold pasteurization brings the opportunity to treat liquid foods in more remote locations like small villages that have limited space and sparse access to energy. Treated products do not have to be chilled post processing as the bacterial contents are on pair with UHT treated products, thereby removing the need for a cold storage supply chain present in developed countries. This capability will have an enormous impact on the public health and food safety in many parts of the developing world.
