Kubota Corp. said its new Super Platon pellet screening system detects black spots or off-color contaminants as small as a tenth of a millimeter in a stream of resin pellets, using four high-resolution sensor cameras.
It can be installed in-line or off-line after the pelletizer and vibratory size screener to detect and remove pellets that are stained, spotted or discolored. In a new feature, the light source is from LEDs arranged in a dome configuration, which Kubota said allows for the screening of transparent materials.
Kutoba, based in Osaka, Japan, makes gravimetric feeders and pellet screening equipment.
