Integrated grinder for wheat and grain

Achieve superior grinding performance and energy efficiency with this fully integrated system, designed to optimize product distribution and energy recovery while ensuring food safety through residue-free cleaning and precise temperature monitoring. Ideal for streamlining operations and reducing costs in your production line.

Grinds and Homogenizes Grains and Feed

The Arrius MRRA from Bühler Group is a revolutionary integrated grinding system that offers seamless operation for flour mills and food processing industries. This system sets itself apart with fully integrated components, including a pre-stressed, backlash-free roller pack and an asymmetrical feed module, ensuring homogenous product distribution across the roller length. Capable of processing a range of grains, such as wheat, corn, and barley, the Arrius delivers high-quality end-products like whole wheat flour, semolina, and cornmeal with exceptional precision.

Designed for high throughput, the Arrius operates continuously and can be monitored via remote devices using an integrated web server. It includes advanced automation features, such as roller temperature measurement and motor-driven grinding gap adjusters, ensuring optimal performance and exceptional energy efficiency—saving up to 10% in energy consumption. Constructed with food-grade stainless steel materials, the system adheres to stringent food safety protocols, featuring a hygienic design that allows complete cleaning under the machine.

With modular options including four-roller and eight-roller versions, and roller lengths ranging from 1000 to 1500 mm, the Arrius can be tailored to specific operational needs. Its “plug-and-play” design enables quick installation and integration into existing production lines, while maintenance is streamlined with the ability to change the roller pack in under an hour. Bühler provides comprehensive engineering support, including process optimization and training, ensuring that the Arrius MRRA elevates your grinding operations to new standards of efficiency and quality.
