Separation of different kinds of grains


olour sorting has become an integral and indispensable part of every grains and seeds processing line, whether intended for food production or for other purposes. In the past the electronic sorters were used to separate contaminants and foreign seeds having a different appearance, while today the end users’ demand has gradually changed towards stricter and challenging sorting needs. These changing requirements have encouraged advances in technology and the development of more and more sophisticated Optical Sorters. Traditional colour sorters for separation of impurities through monochromatic cameras are still in use today, but the ever-stricter human food standards have led to a request of a greater efficiency in identifying impurities. CIMBRIA is continuously focusing in research and development of the ultimate technologies to get the best sorting performances and SEA CHROME represents the latest electronic sorter with the ability to combine Real FullColour cameras with InGaAs and NIR technologies. With the use of high-tech Full-Colour cameras and software capability to work beyond the light spectrum of the human eye, SEA CHROME can identify defective elements not only by contrast, but can separate unwanted grains with similar colours, textures and shapes. SEA CHROME is appreciated and applied in very challenging situations, for which the highest sorting accuracy is required. It means that identification and abatement of damaged kernels such as Fusarium or Deoxynivalenol

The latest challenge of sea chrome

(DON) is now possible, as well as the chance to distinguish elements containing gluten from gluten-free cereals (maize, rice, buckwheat) and also grains difficult to separate with conventional monochromatic or bichromatic cameras, such as wheat from barley and vice versa. Demand for colour sorting equipment continues to rise in line with the ever-increasing number of standards, that’s why customers install SEA CHROME as a necessary part of their seed and grain processing plants. In Europe, Africa, Canada and USA several Cimbria SEA sorters are supplied to the agricultural/food sector to remove colour defects from cereals running in standard set up and, when using the InGaAs cameras, they are able to perform challenging separations, such as un-hulled from hulled grains. SEA CHROME is equipped with full-color RGB cameras and shape-sizing integrated function, to sort impurities according to their geometric characteristics. In combination with HSI software system, allowing a near human eye vision, SEA CHROME is successfully installed even for the separation of soft and durum wheat by seed producers. SEA CHROME is available from one to seven chutes, to satisfy high-capacity demands. Program settings and adjustments are performed through user-friendly software, which displays the real image picture directly on the touchscreen, to help identifying the defective elements to sort out. SEA CHROME represents the state-of-the-art optical sorting technology, able to match the increasingly stringent requirements of the food and seed industries, with the ability to detect and reject products having a similar color but with different shades, thus ensuring that safety and purity requirements are met.
