Optical sorter for wheat applications
Effortlessly enhance product purity by eliminating color defects and foreign materials, ensuring superior quality in high-throughput grain and food processing operations.

Sorts and Purifies Grains and Food Products
The Optical Sorter DR-M from Bühler Group offers an innovative solution for precise grain and food sorting with exceptional ease of use. This equipment employs state-of-the-art optical sensors and SortJet ejectors to accurately detect and remove color defects and foreign matter, essential for achieving up to 99.9% purity in applications such as wheat flour, rice kernels, and almond halves. With processing capacities of 5 or 7 chutes, each equipped with 64 high-performance ejectors, it ensures high throughput for continuous, automated operations.
Designed for seamless integration into existing production lines, the DR-M features new sorting software and hardware that minimize operational intervention. Its energy efficiency is enhanced by reducing compressed air consumption by up to 40%, making it cost-effective in the long run. The integrated feed regulation system guarantees a consistent product stream, critical for reliable sorting performance.
Built with robust construction, the DR-M offers options for stainless steel configurations to handle various material requirements. It complies with stringent safety standards and provides quick, easy maintenance with local support available worldwide. Customizable chute and module upgrades, alongside detection technologies, are available to tailor the system to specific processing needs.
