Key Technology introduces Veryx digital sorters for nuts and dried fruits, achieving unmatched color grading and shell while eliminating false rejects.
They can identify and remove foreign material (FM) and defects such as small, loose and embedded shell fragments, membrane material, insect damage, surface scratches, color-based defects, stems, rocks and glass.
They are ideal for sorting walnuts, almonds, hazelnuts, pistachios, peanuts, pecans, cashews and dried fruit such as raisins, prunes, cranberries, apricots, figs and dates.
With the machines, processors can make grade with fewer passes through the sorter, increasing productivity and reducing product breakage.
The sorters can be configured with front- and rear-mounted laser sensors and cameras to achieve all-sided surface inspection.
Each unit has the multi-sensor Pixel Fusion, which combines pixel-level input from multiple cameras and laser sensors to more clearly differentiate good product, defects and FM.
With Pixel Fusion, Veryx consistently removes the most difficult-to-detect FM and defects without ‘false positives’.
The next-generation four-channel cameras and laser sensors on Veryx offer twice the resolution of previous generation sorters to detect smaller pieces of shell, FM and product defects.
The accuracy of the detection system is paired with a high-resolution ejection system, which features the closest spacing between air nozzles of any nut and dried fruit sorter in order to better target and remove defects.
Intelligent software manages the air nozzles’ actuation strategy to suit the size, shape and weight of each object being removed.
The combined precision of the detection and ejection systems results in the most complete removal of shells, FM and defects without sacrificing good product to the reject stream.
Meanwhile, the patented Chycane chute has a patented concave shape that stabilizes product as it transitions into the inspection and ejection zones, which helps maximize detection and removal accuracy.
The sorting system includes specialized infeed and collection shakers designed specifically for each product to gently handle fragile nuts and effectively move sticky dried fruits without damage.
