New Fluorescence-Sensing Laser Sorter Detects Chlorophyll Levels

Tuesday 1 May 2007

Key Technology introduces FluoRaptor™, the new fluorescence-sensing laser sorter designed to maximize the detection and removal of defects, extraneous vegetable matter (EVM), and foreign material (FM) based on differing levels of chlorophyll as well as color, size, and shape. Using the most powerful laser in the food industry in combination with Key’s proprietary color cameras, FluoRaptor achieves superior product quality and speeds product changeover for processors of fresh cut products and a variety of fresh and frozen vegetables and potato products.

Compared to competitive fluorescence-sensing sorters, FluoRaptor dramatically speeds product changeover. Camera-only based fluorescence-sensing sorters typically take three hours to change over from a fluorescence-sensing application to other applications because the lighting and in some cases, camera systems must be changed. Other laser-based fluorescence-sensing sorters require changing mechanical parts. FluoRaptor eliminates such mechanical change parts, which enables the sorter to be changed over in seconds by simply recalling the appropriate product setting on the control panel.

With the greatest laser power density in the industry, FluoRaptor improves the signal-to-noise ratio to produce a more accurate product signature, which makes detection more robust. With the highest resolution laser scanner in the food industry, Raptor detects the smallest defects.
