Optical sorting system
April 7, 2014
Used with diced and small fruits and vegetables, the TOMRA Iris II optical sorting system uses top and bottom sensor banks to view each object “in flight” with a combination of LED illumination in the visible and near infra-red spectral zones; charge-coupled device cameras perform targeted spectroscopy with 1mm precision. The system views and analyzes attributes such as color, shape, blemishes and foreign material. First-grade produce passes through the machine, while defective produce is redirected into a stream by intelligent air nozzle ejectors. An intuitive touch screen provides quality control and feedback.
