Frequently Asked Questions
Lyras cold pasteurization systems are designed to treat liquids ranging from high to low transparency. We are specialized in the treatment of liquid foods, e.g. milk, plant-based drinks and juice, but we are also experienced with treating non-food liquids.
YES! Our systems meet all the food safety requirements through cold pasteurization. Apart from fulfilling all the requirements, there is also other benefits, as cold pasteurization relies on UV-light rather than heat, no particles burn to the surface, thereby reducing the need for cleaning and use of chemicals.
With Lyras’ new and patented system comes many benefits including: higher quality, energy efficiency, a more sustainable pasteurization, extended shelf life and much more, which you can read about through the following link: Technology
The main challenge in using UV-light, is the transparency of the product. The reason why transparency poses a challenge, is that all the bacteria present in the fluid, must come into contact with the UV-light, for it to be inactivated. A product with low transparancy, such as milk is therefore harder to treat, than for example a see-through liquid such as water.
We at Lyras however have solved this challenge with a new and patented system. Lyras cold pasteurization technology uses UV-lamps to generate a disinfecting light. The system has integrated light filters, which removes unnecessary wavelengths, and thereby we maintain a high product quality meanwhile inactivating bacteria and spores. Furthermore, the unique design geometry creates a turbulent flow, to ensure the entire volume of liquid is exposed to the UV-light. This technique eliminates the traditional challenges to UV-pasteurization, meanwhile being a greener and more energy efficient way of pasteurizing.
With this technique Lyras can pasteurize various products with different viscosity and transparency levels, such as following: Milk, juice, wine, mixers, soda, brine, process water, non-food liquids, plant-based milk, whey, cheese and more.
The costs of service will vary depending on your setup, we can however say that with one of our affordable service contracts you will not run into any unexpected costs. We will assure that the annual service check is performed following all standards and all wearing parts, such as lamps and coils will be replaced.
This is a highly complex question since the cost of the units vary greatly depending on the size of the system, the sensitivity of your product and much more. Do feel free to contact our sales team to get a price estimate for your production at: firstname.lastname@example.org
Yes, we do have the possibility of doing leasing agreements, please reach out to our sales team to hear more at: email@example.com
Generally, we say that any liquid food can be cold pasteurized, and it is done faster, gentler and more efficiently than other solutions do it. We have even been treating liquids such as soaps and balsams.
Foods include: Milk, juices, kambucha, wine, brines, blood plasma and many more.
As the milk pasteurized by Lyras does not have heat, will the consumer think they are drinking RAW milk - any consumer resistance?
The consumer will not think that they are drinking raw milk, but the product will have a taste that bears a resemblance to raw milk. Of course, we cannot say that everyone will like the product better, but there has been no resistance towards the minute changes in taste.
The process of cold pasteurization does not require any heating, water or cooling to treat the products to HTST standards.
No! there are no food safety concerns. Our solution is hygienically designed with certified food-grade materials and no glass-food contact surfaces. Furthermore, our solution meets the highest safety standards and HACCP requirements.
In most cases, Yes! Infact with CPS you could process your liquid food at a fraction of the cost compared to HPP. If you would like to hear if CPS is an optimal solution for you, please reach out to our sales department at Sales@lyras.dk
Each time we deliver a system to a specific liquid food, we have assured that it can be treated without any damage to the product. The system will be specifically optimized to your exact product specifications and if all procedures are then followed there will be no risk of fouling and change in smell of your product.
