Cherry Tomato Grading

GP Graders’ AirJet® electronic graders for cherry and grape tomatoes utilize the most advanced technology on the market. This cutting-edge technology helps you to achieve the best possible returns for your fruit, by dramatically reducing sorting and packing costs. AirJet® electronic graders detects external color defects including cracks and marks, and separates by color and size. 

Fast, gentle and accurate, GP Graders’ electronic AirJet® grader sorts cherry and grape tomatoes at a speed of 30.2 units per second per lane, up to 1 ton per lane per hour, yielding high productivity while maintaining grading accuracy.

SUPERIOR CAMERA TECHNOLOGY

Our new HD cameras give the sharpest picture resolution for size, color and defect analysis. We are leading the industry and our B&W, Color and NIR HD cameras are located directly over the rotating tomatoes, which then take synchronized images, ensuring no parrellax errors corrupt the image analysis. High intensity pulsing LED lighting provides intense illumination of fruit under the cameras, and removes “light glare”. 30 images of the total surface area of each tomato are captured for analysis, which means GP Graders have achieved a new level of analysis, unprecedented in the fresh produce industry. High definition digital color cameras separate the slightest color differences on the tomato for high quality produce.

SIZE SEPARATION

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

Our software can measure up to 30 cherry or grape tomatoes per second!

COLOR SEPARATION

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, including blush. For specific products, like cherry and grape tomatoes, this module is essential.

The AirJet® achieves perfect color separation and provides consistent and uniform pack color. Multiple color ranges for any grade of tomato can be run consecutively, while color blemishes including percentage skin coverage is programmable and detectable.

DEFECT SORTING

How many rotten spots does a cherry tomato have? What percentage of the tomato is marked – and what is the most rotten area? For some properties of the fruit, the color module alone is not enough. Shape is also important to determine and distinguish specific properties and defects. For these properties the intelligent quality module is the solution. In combination with infrared cameras, even defects and splits can be detected.
