Almonds were fed through the bulk flow x-ray system in a consistent flow usually using a vibratory conveyor. Results using this technique are very accurate compared to online installations. Quartz stones and standard test sample spheres were introduce on top of, below and inside the product for accuracy testing. Automatic detection of 85% to 95% of the quartz stones supplied by a vendor was possible with the best results being seen with a product depth of 1.5” or less. Automatic detection is indicated by the contaminant being highlighted in red. pink, green or blue (algorithm dependent) on the x-ray image for easy analysis.
