Strawberries & Berries Optical Sorters by Protec

Strawberries, blueberries, blackberries, raspberries and other berries are accurately sorted, foreign bodies as well as small animals that may have been picked up with the harvest are removed. Protec-designed vision and lighting systems installed on the machines can detect crumbled or rotten, black, green, and off-white strawberries and berries according to the color standard set. Defective products are removed with extreme precision, guaranteeing that only quality products are sent for processing.

The Extrasorter separates unrip or rotten fruit from the production line. It also identifies foreign bodies such as leaves, wood and plastic. The output flow therefore only contains fruit suitable to be processed. The sorter features an effective colour-based selection system to identify fruit of the incorrect colours and an infrared lighting system to detect foreign matter, which would be overlooked by conventional vision systems which use visible light. The electro-pneumatic ejector blade system effectively targets small fruit such as lemons, limes and clementines and large sized fruit such as oranges and grapefruits. ExtraSorter models: 20C production of 23 T/hr and 500mm belt width; 30C production of 34 T/hr and 750mm belt width; 40C production of 45 T/hr and 1000mm belt width and 60C production of 60Ton/hr and 1500mm belt width.

The Duett is an air blast sorter with 2 or 4 cameras for diced, sliced berries. The sorter identifies defects such as dark marks, pip residues, stalks and other impurities in various types of unfinished apple products. The product is conveyed by two belts; the first one is horizontal and the second one is tilted.
At the output of the conveyor belt, the product is illuminated by a powerful light; the vision system inspects the product on both sides and the defects
are rejected by an accurate and powerful compressed air ejection system. Duett ensures maximum sorting efficiency with minimum error.
Duett models: 50-50 production of 3-9 T/hr and 1050mm belt width; 150-150 production of 5-15 Ton/hr and 1563mm belt width. 

For vegetables and diced fruit sorting the new DixAir has proved to be the most efficient in detecting defects such as off-color, rot, and discoloration in black, green and white colors. The sorter uses a high-speed and high-resolution system of linear cameras, that examines the product moving on the conveyor belt. The images are analysed on an electronic card designed by Protec, that uses the latest integration and speed technology to ensure maximum performance. Defects as small as 0.5 x 0.25mm in size are analysed in conjunction with a powerful image processing software. The sorter is also provided with a unique back-lighting device installed below the belt to illuminate the product and better show the defects. DixAir models: 50-50 production of 30 T/hr and 500mm belt width; 100-100 production of 60 T/hr and 1000mm belt width; 150-150 production of 90 Ton/hr and 1500mm belt width.
