Optical sorting Discovery

Discovery is an optical sorting machine with the highest resolution cameras to examine the product on the conveyor belt. The system is used to check whole or cut agro-food products: Fruit and Vegetables.

Discovery can dispose of colour defects, marked produce and foreign bodies also the same colour as the good product. The product is fed on the inspection belt used to stabilise the product so it doesn’t roll off. The inspection zone is clearly separated from the ejection zone to avoid product sprays which can prejudice selection over time.

Discovery is equipped with an air reject system with 288 electrically controlled ejection valves. It can have a single ejection system, or in 3Way mode, can have two reject systems that differentiate unusable produce from defects considered second choice.

 

Description

Discovery is an Octa-Chromatic machine equipped with the following technologies: NIR (Near InfraRed) technology;
Visible Color analysis; Chlorophyll analysis; Translucency analysis; Shape analysis.

  • NIR technology can detect the presence of rot and foreign bodies.
  • Visible Color analysis allows colour defects to be detected, such as green products, yellowing, etc.
  • The Chlorophyll analysis allows very accurate detection of foreign bodies in products with high chlorophyll content (lettuce, peas, green beans).
  • Translucency analysis enables detection of stones in the dehydrated fruit and contaminants which are on the side towards the conveyor belt.
  • The shape analysis is used to detect small pieces of fruit and green beans. Furthermore, it enables removal of waste as pieces are too small.
  • An ethernet connection is available for remote control.
  • The machine detects statistical data on rejected products for quality analysis of the selected raw material.
