TECHNOLOGY

SIZE SEPARATION

The dimensions of each product are calculated using multiple images of the product. Our software detects the stem connection: 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.

The color module enables you to specify the colour that you wish to grade the fruit using live feedback from the high-resolution cameras. The AirJet® achieves perfect color separation that provides consistency and uniform pack color. Multiple color blemishes including percentage skin coverage is also detectable.

COLOR SEPARATION

GP Graders’ AirJet® technology is programmed to detect both internal and external defects. It successfully detects and removes internal defects that affect blueberries such as softness, bruising, cell breakdown, shriveling and compression damage.

The detection of both internal and external defects means consistent and uniform removal of reject-grade blueberries, resulting in a huge reduction in the number of sorting staff required.
