Key Technology, a member of the Duravant family of operating companies, introduces their enhanced Herbert OCULUS optical sorter for whole potatoes at Fruit Logistica hall 6.1 stand A-60. Ideal for fresh market potatoes or whole potatoes prior to processing, this enhanced system improves performance to better find and remove potatoes with defects. Its superior sorting capabilities help ensure product quality while reducing labour requirements and achieving consistent line capacity despite fluctuations in incoming raw product quality.


“The value of Herbert OCULUS for the potato industry has never been greater. With extreme weather impacting the quality and quantity of harvested crops worldwide and labour availability at an all-time low, automating inspection with OCULUS helps customers achieve grade specifications while maximising yield and profitability,” said Antoine van Bree, President, Key Technology – EMEA and Asia. “Driven by continuous improvement, 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 minimise 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 colour cameras. Compared to traditional cascade sorters, this unique method of sorting offers gentler handling and provides 20 percent more surface inspection to maximise 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, colour and texture. Its advanced detection capabilities enable the sorter to remove a wide range of colour defects, diseases and surface abnormalities including skin discoloration, green and dark colours, bruising, mechanical damage, blackleg and silver scurf.
