TrueSort grading software has a modular design. The software can grade crops based on weight, size, color, external and internal quality.

WEIGHT

The weight of fruit and vegetables can be determined on a cup system and a roller system. Weighing with an accuracy of within half a gram is possible, even at high speeds. The system automatically corrects for the weight drift of each cup caused by swell of the machine, temperature differences or dust build-up during the day. This guarantees the most reliable data for the best results!

SIZE

The dimensions of each product are calculated using multiple images of the product. Our software detects the stem and the center of gravity: in this way, we know which diameter must be measured. Specialized algorithms determine the orientation of the product. Diameter, length, curvature, surface – but also shape can be determined.

Our software can measure up to 10 apples or even 30 cherries per second!

COLOR

The color of the fruit is highly representative of the quality and ripeness of the fruit. The color module enables you to specify the color on which you would like to grade the fruit, using live feedback from high-resolution cameras. In this way, you can accurately specify the properties of the fruit, such as blush. For specific products, like asparagus, this module is essential.

EXTERNAL QUALITY

How many rotten spots does a pear have? What percentage of the apple is rotten – and what is the most rotten spot?

For some properties of the fruit, the color module alone is not enough. Shape and context are also important to determine and distinguish specific properties, such as naval, stem, calyx, mould, scratches, and other defects. For these properties the intelligent quality module is the solution. In combination with infrared cameras, even defects and bruises just under the skin can be detected.

INTERNAL QUALITY

We have developed a projector to accurately assess the internal quality of a product. For this, we are one of few suppliers using the full transmittance technology, as a result of which the entire fruit can be illuminated and not merely a part of the fruit. In this way deviations like rot, brix, dry matter, acidity and ripeness can be determined accurately!
