Digital Laser Sorter
Key Technology introduces the next-generation digital laser sorter, Taurys™. Featuring the latest advances from the leaders in digital sorting, Taurys achieves faster and more precise sort decisions to set new performance standards. With its powerful Enygma™ sort engine, new architecture, a reengineered and patented Chycane™ infeed chute, new ejection manifold, and the most effective and reliable lasers, Taurys handles higher incoming defect loads, increases detection resolution, and improves the accuracy of defect and foreign material (FM) removal.
Taurys improves sorting efficiencies and reduces false rejects to help food processors improve product quality and increase yield. “Taurys is the most advanced digital laser sorter on the market. It’s our first new product since our merger with Visys and incorporates their leading-edge technology. The Enygma sort engine enables Taurys to make faster and more accurate decisions, which allowed us to make several significant design changes that maximize performance,” said Marco Azzaretti, Advanced Inspection Systems Product Manager at Key Technology. “Taurys offers immediate improvements in sorting efficiencies. It also lays the foundation for sorting advances like fusion sorting, which requires a tremendous volume of data to be analyzed simultaneously.” Faster data processing enabled the sorter’s architecture to be changed to reduce the distance from the inspection zone to the ejection zone, resulting in superior product control and improved sorting efficiency. Combine this with a new ejection manifold that features twice the number of ejectors in the same space, and Taurys maximizes ejection accuracy to increase defect and FM removal and reduce false rejects, resulting in improved yields. The powerful new sort engine enables the fusion of multiple sensor characteristics into a single sort decision. This “fusion sorting” capability differs from traditional food sorting that makes sort decisions based on the product attributes collected by each sensor separately. The fusion of data creates a higher contrast for more accurate differentiation of good products from defects and FM. Faster data processing allowed the patented Chycane infeed chute to be reengineered to maximize control of the product. Compared to traditional waterfall sorters, the Chycane chute enhances product stability to produce a more consistent trajectory through the inspection and ejection zones. This increases removal of defects and FM and reduces false rejects resulting in improved product quality.
Taurys is a 100-percent digital laser sorter that eliminates the transmission of analog laser signals, which are prone to signal degradation and data loss. Taurys is not affected by noise or interference, which enables this sorter to identify finer details and remove smaller defects and FM. Additionally, the sorter’s laser scanner, which typically operates at 12,000 rpm (revolutions per minute), is now able to operate up to 24,000 rpm to increase inspection resolution and identify even smaller defects and FM. Key can configure Taurys with the widest range of detection wavelengths to sort on the color and/or structural properties of objects to meet each application’s requirements. This high performance chute-fed sorter is ideal for nuts, dried fruit, frozen fruits and vegetables, and other products such as fresh-cut produce, confections, coffee, and snack foods. It can be located near the beginning of the processing line to eliminate defects and FM prior to value-added processes, or near the end of the line where precise defect and FM removal assures final product quality prior to packaging. With its 1200-mm (47-inch) wide inspection zone, Taurys sorts a maximum capacity of 3 to 15 metric tons (3.3 to 16.5 short tons), depending on the product. Taurys features an icon-based graphical user interface (GUI) that is easy to learn and use, reducing operator training and simplifying operations. Product settings can be stored and retrieved for fast product changeovers. The GUI can reside locally and can be accessed remotely via its OPC-compliant infrastructure, enhancing the flexibility in the operating environment and easing access for remote factory troubleshooting and application assistance.
