New generation of optical grader for unwashed potatoes


Dubrulle DOWNS, the French manufacturer of reception and storage solutions for potatoes, has launched the DOWNS CropVision®, a new generation optical grader for unwashed potatoes. 

Fitted with the latest technological innovations, it allows a high-speeded and qualitative grading of the potatoes before the storage (to 100 tons/h).
Result of four years of development, the DOWNS CropVision® is fitted with industrial cameras coupled with an algorithm of Artificial Intelligence.

The combination makes it possible to observe and analyse the whole surface of the product (360°) in order to classify it according to its quality - clods, stones, other waste, good potatoes, green potatoes, cut potatoes, spoiled potatoes, mishaped and cracked potatoes.

The machine is fitted with three possible exits for the product: A first exit for the product to keep, a second one for the waste and a third one for second category potatoes. According to the user’s requirements, the ejecting fingers will lead the product to the right exit.

Thanks to the 360° scan of each potato, the DOWNS CropVision’s® user has access to information about the stored potatoes, such as the size of the potatoes for each batch of product or their quality.

It has a user-friendly touchscreen that can be integrated into DOWNS receiving hoppers and graders.
