Key Technology has launched the Prism2, the second generation of its sorting equipment technology, designed to ensure quality standards in a range of solid food applications.
Modelled after Key's smaller-capacity Optyx sorter, the more compact Prism2 handles the same capacity levels as the original Prism with a shorter, narrower footprint. A distinctive new feature - a built-in graphical user interface and control module - further conserves floor space. The user interface can be manufactured on either the right or left side of the machine to fit any plant floor plan, the company claims.
Like its predecessor, the Prism2 features the same "sorting engine" which includes electronics, user interface electronics, cameras, and flexible camera configurations for defect detection and viewing versatility. Camera options include full-colour, Vis/IR or monochromatic for maximum application-specific effectiveness and efficiency. The configuration is best suited to a range of fresh and processed foodstuffs, including sweets, carrots, potatoes, tomatoes and meats.
Five available camera configurations, plus three camera options, provide 15 viewpoint selections to fit the application. The updated body design is completely sealed for protecting electronic components in a wet production environment.
According to Key Technology, the system's high-resolution colour recognition distinguishes over 2.1 million different shades. An Advanced Vision Processor (AVP) combines an industrial PC and a proven, proprietary vision engine using pipeline architecture. Custom algorithms provide real-time video processing and valve firing. Size and shape recognition is available to match unique product requirements.
New high intensity discharge (HID) lamps provide more consistent illumination by flooding the inspection zone with light. The company also claims that the smaller, clip-in, HID lamps are easier to replace than fluorescent bulbs since no extra space is required for changing.
New design features are also said to simplify maintenance and product changeovers. A new, simple, easy-to-reach door design allows easy access to maintenance points. Added to that, open access to the new quick-release belt is said to make product changeovers easy.
Key Technology, an ISO-9001 certified company, is a leading designer and manufacturer of process automation systems, integrated electro-optical inspection and sorting systems, and processing systems. The company maintains demonstration and testing facilities at its headquarters and manufacturing divisions in Walla Walla, Washington, USA, and in Beusichem, the Netherlands.
