SYSTEM AND TECHNIQUE FOR DETECTING FOREIGN MATERIAL IN MEAT
摘要
Systems and techniques for detecting the presence of foreign material in food utilizing optical backlighting and/or ultrasonic inspection are presented. In optical backlighting, a substantially monochromatic light source optically backlights a food stream with source light having a wavelength between about 500 and 600nm. An image of the food stream is captured and the presence of foreign material is determined when a portion of the detected image exceeds a predetermined threshold. The technique is especially suitable for the detection of bone in chicken meat, and the light source can be a planar array of green LEDs. In ultrasonic inspection, a process stream is interrogated with pulses of ultrasound and the presence of foreign material is determined based on the detected off-angle ultrasound scattering response.
