Upgrades made to Herbert Oculus.

AN enhanced optical potato sorter is to be introduced by Key Technology at Fruit Logisitica next month.

The Herbert OCULUS optical sorter is ideal for fresh market potatoes or whole potatoes prior to processin, finding and removing potatoes with defects. 

Its sorting capabilities help ensure product quality while reducing labour requirements and achieving consistent line capacity despite fluctuations in incoming raw product quality, according to the manufacturer.

Antoine van Bree, President, Key Technology – EMEA and Asia, said: “We upgraded OCULUS to offer our customers a more innovative, effective and reliable solution for the changing market.”

The enhanced Herbert OCULUS features new cameras that offer twice the resolution of the previous generation cameras to identify smaller, harder-to-detect defects. A more advanced 64-bit operating system replaces the previous 32-bit system to achieve a more sophisticated analysis of each tuber. New longer-lasting air cylinders with better seals run at a lower pressure to minimize energy usage, reduce maintenance and lessen operating noise while maintaining high performance. Lighter reject fingers move faster to improve reject accuracy.

Herbert OCULUS conveys the potatoes over a series of rollers to present a complete 360-degree view of each tuber to the digital infrared color cameras. Compared to traditional cascade sorters, this unique method of sorting offers gentler handling and provides 20 percent more surface inspection to maximize defect removal.

Available in multiple sizes for a range of capacities up to 40 metric tons of product per hour (88,000 lbs / hr), Herbert OCULUS recognises size, shape, color and texture. Its advanced detection capabilities enable the sorter to remove a wide range of color defects, diseases and surface abnormalities including skin discoloration, green and dark colors, bruising, mechanical damage, blackleg and silver scurf.
