General Overview

 

CSort colour sorting machines are high precision machines, being easily operated and making outstanding sorting results – up to 99.9% of output product purity.  Colour sorting is widely used in food industry, especially where visual product control is demanded, like the sorting of cereals, legumes ad oilseeds, nuts, grass seeds and even frozen or dried fruits and berries.  Colour sorters also successfully meet the needs of non-food industries, like recycling of glass and plastic, as well as sorting of wastes, salt and minerals.

 

Why Optical Sorting Technology is Necessary – Trends that can cause problems

 

  • The food industry is growing significantly and facing productivity, economic, efficiency and environmental pressures more than ever before
  • The increasing demand for the world’s food resources has made the food supply complex and multifaceted, with a global supply chain bringing many benefits but also presenting a major food safety headache
  • The longer and more complicated the chain is, the higher the risk of contamination and spoilage
  • Effective sorting and quality analysis systems can play a critical role in enhancing food safety

 

Implementing Optical Sorting Technology can:

 

  • Significantly reduce the risk of contamination from aflatoxins and foreign material
  • Increase food safety on the production line and
  • Offer a smart investment for processors and manufacturers

 

The benefits of sorting technology in general:

 

  • Camera-based optical sorters can consistently detect and remove foreign material, unwanted rot, greening defects, blemishes and damage.
  • This ensures higher yields and a safer, higher quality final product going to consumers.
  • Sorting machines can increase processing capacity and lower labor costs, all while producing food of the highest quality and safety standards.
  • Additionally, the camera-based technologies applied in the different optical platforms allows processors to specifically target their needs in each step of the process.
  • Camera technology is increasingly identifying defects in produce, ensuring higher resolution and better contrast, and the technology used will continue to improve in quality and food safety.
  • In addition, the ability to employ data management when using machines means that more real-time monitoring and controlling of production lines is possible, creating further efficiencies.
