Onion grading technology

Internal quality

Our internal quality system detects internal rot (core, ring and neck) of yellow, red and white onions, along with other internal characteristics including early stage sprouting. Ellips TrueSort™ electronics 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

For external quality, such as shape and context, Ellips incorporated HD cameras and LED lighting into our vision systems.
TrueSort™allows customers to quickly establish “variety specific” grading parameters that provide consistent detection of the most prevalent external defects. Our software succesfully detects  balding, sour skin, external rot, black mold, sprouting, misshapen/doubles and mechanical damage.
Once the defects are identified, our grading software sorts the onions into various grades (i.e., premium, second, peeler, cull, etc.).

Colour separation

Based on live feedback from the cameras our system is capable of determining the colour on which you want to grade the onion (and to detect bald onions).
By rotating the product under the camera it is possible to combine consecutive images of one camera or images from multiple cameras at various angles in order to receive as much information as possible. Ultrafine colour separations are obtained through our TrueSort™ intuitive software that enables operators to quickly create or modify colour spectra.

Size separation

Our size module is able to determine properties of the onion and to detect loose skins which can still be sticking to the product. The measurements are more reliable by looking at the product from various angles. Hence the onion is rotated under the camera and 10 images are taken of each product. This permits you to calculate the diameter (with an accuracy of 0.1mm), length and surface area.

Weight

The weight of every single onion can be measured on a cup system or roller system with a built-in weighing system. Accurate weighting (+/- 1 gram) is possible, even at high speed (up to 10 cups/second). The system automatically takes into account factors such as temperature differences and dust accumulation throughout the day.

No time to waste

Grading with an Ellips equipped system ensures each onion to end up at the right place. Quality guarantees will help you opening new markets and customer satisfaction is improved with on-time delivery of products.
