Uzwil (Switzerland), June 3, 2024 – Bühler’s endless commitment to innovation is bearing new fruit for customers. The Swiss technology group is launching the new roller mill Arrakis, the successor of the Airtronic, considered an icon in the history of milling for its durability and straightforwardness in operation. The Arrakis takes these qualities to the next level with increased efficiency, reliability, and simplicity of operation.
Arrakis is Bühler’s latest addition to its state-of-the-art grinding portfolio; it is the result of the commitment to excellence of a research and development team. At the heart of Arrakis is the grinding unit – a true pillar that customers can rely on thanks to its stable grinding performance. The patented grinding gap adjustment ensures rigidity and stability over time to maximize grinding performance.
A cast stand is used as the load-bearing element. Cast stands dampen vibrations from roller mills and thereby increase the longevity of the installed components. Product detection is carried out via a load cell, a proven and widely adopted method for accurate measurement. The load cell sensor regulates the feeding gap to provide a stable product flow across the grinding rolls for maximum efficiency. In addition, foreign object protection prevents damage to the rolls, increasing longevity of the roller mill.
“Airtronic was a solid machine, and its durability is exactly what made it beloved by millers all around the world,” says Marcel Scherrer, Head of Business Unit Wheat & Rye at Bühler. “We took what we learned from the success of this icon and used it as a foundation to build upon when developing Arrakis.”
Urs Schwendener, Product Manager in Milling Solutions at Bühler Group, adds: “With the Arrakis, we are completing our grinding portfolio, addressing the different needs of customers. We can provide our customers with the right solutions to meet their daily challenges.”
Easy and straightforward to use
Another highlight of Arrakis is its ease of operation. Its intuitive interface makes controlling and monitoring simple and straightforward. Thanks to its secure remote access function, the machine can be operated through various digital devices such as a PC, tablet, or smartphone and from anywhere in the plant.
As the new solution is built on the same footprint of its predecessor, Airtronic, replacements can be made one-to-one, simplifying the installation process as no complex building adaptations are required. Connecting the fixed speed feeding roll to the main roll’s drive guarantees a more streamlined system that is easy to install and maintain. “We also thought of our customers who want to upgrade their systems. Conversions of existing productions are usually very complex, and the available space is limited. With the Arrakis, we have the opportunity to replace Airtronic and other roller mills in a short time, thereby saving valuable production time,” says Urs Schwendener.
The feeding unit is equipped with a cleaning flap, which ensures the complete discharge of the remaining product and easy cleaning of the feed module. Brushless scrapers remove grain fragments jammed in corrugations. These scrapers significantly improve food safety compared to the traditional scraping brushes that are still in use to this day. The new patented knife scrapers automatically adjust to the surface of the smooth rolls, eliminating the need for manual adjustments and keeping the rolls consistently clean.
“Being the successor of such a beloved roller mill places high expectations on Arrakis. Nonetheless, the introduction of the Arrakis is driving advancements in the industry and helps our customers maintain their competitive edge," says Marcel Scherrer.
