Blueberries

GP Graders’ AirJet® electronic graders for blueberries are the most technologically advanced sorting machines available in 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 internal or external defects including softness, some cracks and marks, separation by color and size.

Fast, gentle and accurate, GP Graders’ electronic AirJet® grader sorts blueberries at a speed of 50 units per second per lane yielding high productivity while maintaining grading accuracy. GP Graders technology can grade crops based on size, color, external and internal quality.

TECHNOLOGY

ACCURATE SIZE SEPARATION

The dimensions of each product are calculated using multiple images of the product. The AirJet® Blueberry detects the stem connection, or bloom. In this way, we know which diameter must be measured. Specialised algorithms determine the height and width of the product alongside the diameter and shape.

PERFECT COLOUR SEPARATION

The colour module enables you to specify the colour that you wish to grade the fruit using live feedback from the high-resolution cameras. This information provides you with an accurate representation of the quality and ripeness of the blueberry judged by its colour to suit your product needs. The AirJet ® achieves perfect colour separation that provides consistency and uniform pack colour. Multiple colour ranges for any grade of blueberries can be run consecutively, while colour blemishes including percentage skin coverage is also detectable.

DEFECT SORTING

GP Grader’s 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. This guarantees that the blueberry defect sorting process is efficient and provides our consumers with the healthiest produce in the market.
