    Potato grading technology

    Internal quality

    Our Ellips TrueSort™ Internal Quality system is the only system on the market today that can accurately detect internal defects on potatoes. With this technology, you are able to see completely through the product (instead of just underneath the skin) by virtually ‘slicing potatoes’ into pieces.

    The software detects flecking, glazing, hollow hearts and other internal defects.

    TrueSort™ is a user friendly system that can quickly modify grading programs to address specific issues or customer requirements. Our system enables higher quality products on a consistent basis.


    External quality

    Our HD cameras enable better visual identification of the potatoes shape and context. TrueSort™ accurately finds the potatoes’ characteristics  and successfully detects the most prevalent external defects such as common scab, black scurf, silver scurf, wire worm, misshapen/doubles and mechanical damage and punctures. Once the defects are identified, our TrueSort™ software sorts the potatoes into various classes based upon defect severity, count or area.

    Colour separation

    Our colour module can determine – based on live feedback from the cameras – the colour of the potato in order to grade the product. Ultrafine colour separations are obtained through our TrueSort™ intuitive software that enables operators to quickly create or modify colour profiles for red, white, yellow or sweet potatoes.

    Size separation

    To measure the entire surface, the potato is rotated under the camera and 40 images are taken of each product. This permits you to calculate the diameter, length and surface area. Defects in shape or position of 2 products in 1 cup or roller can also be detected. Square Measure is a specific potato sizing criteria which is implemented in our Ellips TrueSort™ software.


    The weight of every single potato is measured on a cup system or roller system with built-in weighing system. Accurate weighing (+/- 0,5 gram) is possible, even at high speed (up to 15 cups/second). The system automatically takes into account factors such as temperature differences and dust accumulation throughout the day. Weight is calculated from camera pictures of each potato by an adjustable specific weight parameter. The dashboard that is build-in our TrueSort™ software monitors the average product weight and capacity per hour.
