The natural anti-bacterial properties of UV light have been known for more than 100 years. For this period, the technique has been widely used for disinfecting transparent liquids such as drinking and processing water. The inventor of the raslysation technique found, however, that UV is also capable of treating opaque liquids such as whey, brine, and juice.

In 1864, the French chemist Louis Pasteur developed a method for preserving liquid foods by heating them up and cooling them down in rapid succession – a process that later became known as pasteurization.

Today, almost all liquid food products are pasteurized, including milk, cheese, juice, soda, and plant-based drinks. For that reason, pasteurization is an inevitable part of the consumers’ everyday life, though only a minority is aware of it.

Though at the time revolutionary, conventional heat pasteurization is not without downsides. It is a time-consuming process that lowers product quality while consuming vast amounts of energy in the heating and cooling processes.

Raslysation is a processing technology for treatment of a vast array of liquids. The technology works by combining a turbulent flow pattern with ultraviolet light sources to eliminate unwanted microorganisms in liquids to extend shelf life of the final product.

Like pasteurization, the intention of raslysation is to inactivate microorganisms that contribute to spoilage or risk of disease. Despite similarities, however, raslysation is far less resource-intensive than its predecessor and saves 60-90% of the energy consumption and 60-80% of the water consumption used in pasteurization.

The raslysation technology is a stand-alone unit with PLC, HMI and MCC panels and a feed unit. This makes it a versatile system easily implemented into any production line. Furthermore, the sanitary system is designed for maximized food safety e.g., with no glass-food contact.
