Key features

Sensor Technology

The Halo uses top and bottom sensor banks to view each object ‘in flight’ using a combination of LED, CCD camera and NIR to perform targeted spectroscopy with 1 mm precision. This advanced sorting system views and analyses visible attributes such as colour, shape, blemish, foreign material, as well as ‘invisible’ defects to the product composition.

Gentle product handling is assured by design; the first sort produce gently passes through the sorting machine while the second and third grade are redirected into individual streams by intelligent finger ejectors with precision and accuracy.
