The sugar-end remover is a highly technologically advanced sorting machine which is capable of detecting sugar-ends on raw potatoes, foreign substances and many other defects.
This patented technology is unique worldwide.
The raw and peeled potatoes are scanned by a powerful imaging system, which provides spectra in the near infra-red range with a local resolution of 3mm x 3mm. The detail of the spectral information allows conclusions to the fruit’s chemical composition in every single pixel. Differences in the content of glucose, starch and water are made visible in colours. Sugar-ends, foreign substances, and a number of other defects can therefore be reliably detected.
The machine is constructed small and can be easily implemented in the processing line after peeling of the potato. The potato is moved under the camera by a vibrating conveyor. Defect potatoes are filtered out by a powerful clack system. A module with a working width of 840mm sorts approximately 16 (metric) tons of potatoes every hour.
