Electronic colour sorter grain sesame sortex machine is an optical sorting machine that uses advanced algorithms and digital cameras to sort grains based on their color. The machine captures high-resolution images of each grain as it passes through chute, and then analyzes the color, size, and shape of each grain. The machine's software then uses this information to sort the grains into different categories based on their desired color, eliminating any unwanted or defective grains from the batch.
