Sorting of synthetic granules

In the sorting process, granules are propelled past high-speed, high-resolution colour line scan cameras taking images. The generated image data allows for identification of shape-, colour- and texture characteristics and determination of the product class based on specifically defined classifiers. Post classification, our QualiReader image processing software channels granules to high-speed blow-off valves, accurately sorting different types of granules.
