    Onion Internal Quality Grading with Ellips Grading Technology

    Onion Internal Quality Grading with Ellips Grading Technology

    Internal quality

    The Ellips TrueSort™ Internal Quality system can see completely through the onion (instead of just underneath the skin) and accurately detect internal defects on onions, like internal rot (core, ring, and neck), early-stage sprouting, fusarium and root tear. By virtually ‘slicing onions’ into pieces, you can examine the internal quality and recognize these defects at lightning speed.

    External quality

    One of the biggest challenges in grading onions at higher volumes is that each onion comes in a different size and shape. The Elisam GranTorino handles each variation perfectly. With it’s unique rotating carrier you get a 360° view of each onion, allowing you to analyze the entire surface. TrueSort™ accurately recognizes the onions’ characteristics and successfully detects the most prevalent external defects.

    Deep Learning

    Ellips developed a deep learning toolbox called TrueAI. This toolbox is going to help you with near-perfect grading accuracy and detecting complex defects such as fusarium, root tear and mechanical damage. The new software has been trained using large amounts of data combined with the expertise of quality control personnel. You want the best of both worlds:
    1.  An operator who has knowledge of date quality characteristics.
    2. This new grading technology to meet your customer’s unique demands.

    Colour separation

    Based on live feedback from the cameras we can determine the color of the onion in order to grade the product (and detect balding). Ultrafine color separations are obtained through the TrueSort™ software that enables operators to quickly create or modify color profiles

    Size separation

    To measure the entire surface, the onion is rotated under the camera and 10 images are taken of each product. This permits you to calculate the diameter, length, and surface area. Shape related defects or doubles (2 onions in 1 cup) can also be detected.

    Weight

    Accurate weighing is possible, even at high speed. The weight  of each onion is calculated volumetrically via images from high tech cameras. The TrueSort™ software monitors the average product weight and capacity per hour.
