Herbert OCULUS Optical Sorter for Whole Potatoes

Feb. 7, 2023
Key Technology's whole potato sorter helps to ensure product quality by identifying for a range of surface abnormalities and diseases.

Ideal for fresh market potatoes or whole potatoes prior to processing, the Herbert OCULUS optical sorter improves performance to better find and remove potatoes with defects, helping to ensure product quality while reducing labor requirements.


The enhanced sorter features cameras that offer twice the resolution of the previous generation cameras to identify smaller, harder-to-detect defects. An advanced 64-bit operating system replaces the previous 32-bit system to achieve a more sophisticated analysis of each tuber. Additionally, 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-deg. 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% more surface inspection to maximize defect removal.


Available in multiple sizes for a range of capacities up to 40 mt/hr (88,000 lb./hr), Herbert OCULUS recognizes size, shape, color, and texture. Its 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.
