TOMRA Halo sorter and grader

Wednesday, 27 August, 2014


TOMRA Sorting Solutions has developed the Halo sorter, a sensor-based sorter and grader for fruit and vegetables.

Using top and bottom sensor banks to view each object in flight, the machine utilises pulsed LED, CCD sensor and near-infrared technology to perform targeted spectroscopy with 1 mm precision. It views and analyses visible attributes, such as colour, shape, blemish, foreign material and difficult-to-see defects. First-grade produce gently passes through the machine while second and third grade is redirected precisely into individual streams by intelligent finger ejectors.

According to the company, the system offers users labour reductions of up to 80%, throughput rises of potentially 25%, faster packing, yield increases that can reach 4% and low operational costs.
