What is Laatu?
Laatu is a new in-plant solution for eliminating foodborne pathogens in industrial dry food processing. It exposes controlled low energy electrons to the surface of dry foods without agitating its internal matrix, enabling a better preservation of nutritional, functional and sensory properties of food. Laatu provides an efficient reduction of harmful microorganisms, including spores, with field trials consistently showing a 5-Log reduction or more of Salmonella. It does not use chemicals, water or radioactive sources and has the advantage of a low environmental footprint by cutting the energy consumption by up to 80% in comparison to steam equipment.
With a potential of by capturing processing parameters, dates, times and product batches in real-time, stored reports could be used to support a Hazard Analysis Critical Control Point (HACCP) plan and ensuring the food safety.
This year Laatu will be released for spices and its implementation for other dry food markets is under development.
Why the need for Laatu?
Improving food safety and reducing waste
By working in collaboration with Microsoft, the potential of digitalising Laatu improves efficiency, transparency, and traceability throughout the food supply chain to ensure food safety and reduce food waste.
Preservation of food quality
Due to the limited penetration depth of low energy electrons the technology can offer a gentle surface decontamination with better preservation of nutritional, functional and sensory properties of the food.
Low environmental impact, economically sustainable
Laatu can be easily integrated into existing processes and plant. It uses no chemicals, radioactive sources, or water and consumes less energy when compared to existing microbial reduction techniques.
The Laatu solution
Bühler is constantly working on pioneering, innovative and sustainable solutions for the food processing industry. Our aim is to drive down irresponsible use of natural resources and waste production whilst ensuring that we deliver credible solutions that offer security in food safety. We do this by incorporating new digital technologies, science and in the case of Laatu – physics into our solutions.
How it works
Laatu features specialized and contained lamps that generate a cloud of low energy electrons. Each seed or grain free-falls into the contained area and is homogenously exposed to the electrons, inactivating pathogenic microorganisms present. This process is done in milliseconds.
A process that saves energy and spendings
Production data, including moisture content and other variables, is continually collected from a network of sensors.
On our Microsoft Azure based cloud platform, the data is run through proprietary algorithms, developed on decades of drying expertise.
Dryer controls are manipulated in real time, continually optimizing the drying process, achieving the perfect moisture content.
