FullColour vision system that identifies and sorts even the slightest differences in colour, shade and shape
Alfalfa is native to warmer temperate climates. It has been cultivated as livestock fodder since the time of the ancient Greeks and ancient Romans.
Nowadays, it is cultivated as an important forage crop in many countries around the world. It is used for grazing, hay and silage, as well as a green fertilizer and cover crop. (Source: wikipedia.org)
Dodder attaches itself to a plant and wraps itself around it. If the host contains beneficial nourishment, the dodder produces haustoria that insert themselves into the vascular system of the host. It can grow and attach itself to multiple plants, including several agricultural and horticultural crop species, such as alfalfa, flax and clover seeds.
Docks and sorrels (Rumex spp.) are a genus of herbs in the Polygonaceae buckwheat family. Some of them are nuisance weeds (dockweed). Due to their great adaptability, they are widespread in ditches, meadows, vegetable areas and gardens. (Source: wikipedia.org).
The maximum content of Cuscuta spp. and Rumex spp. in certified seeds is regulated by law. Some seed companies, such as our client Continental Semences S.p.A., have stricter internal standards for Cuscuta spp. and Rumex spp. in order to guarantee high quality seeds to their customers.
CIMBRIA SEA sorting technology is the best-performing solution when it comes to cleaning alfalfa seeds.
In July 2019, CIMBRIA SEA completed the commissioning of a SEA CHROMEX 7 T+T at Continental Semences S.p.A. in Traversetolo, close to Parma in Italy.
The business activity of our historical client is closely connected to the Guarnieri family, which has carried out cleaning of forage seeds since 1874. Today, Continental Semences operates in the seed import & export business on a global basis, with seed cleaning, stocking and packing operations being carried out over an area of more than 30,000 m2. Moreover, the company can count on other agricultural areas dedicated to the research and multiplication of certified seed varieties.
SEA CHROMEX represents the top of the range with a FullColour vision system that identifies and sorts even the slightest differences in colour, shade and shape.
Full-Colour RGB 4096 pixel cameras ensure the highest optical resolution on the market of 0.06 mm. Moreover, the integrated shape-sizing function is a fundamental tool used to separate contaminants having a similar colour, but different shape – such as Rumex spp., which has a triangular shape.
For this challenging application it is important to combine multiple filters through HSI (hue, saturation, intensity) vision systems in order to identify the smallest differences between alfalfa, Cuscuta spp. and Rumex spp.
The SEA CHROMEX setup is realized through photographic acquisition, comparing each seed to a user-defined accept or reject criteria, identifying it as a real defect or as an accepted element.
The EXAGON intuitive graphic and multilingual interface allows user-friendly recipe setup and editing, with the chance to use the same recipe on multiple sorting units and to acquire real-time statistics.
Until now, the separation of Cuscuta spp., Rumex spp. and other harmful contaminants of forage seeds has been performed by mechanical separation, in particular for Cuscuta spp. through electromagnetic machines using iron powder.
Today, the installation of SEA CHROMEX Full-Colour technology is highly strategic, as it provides a boost to final product quality and purity, as well as considerable simplification of the manufacturing process.
CIMBRIA, SEA, AGCO. In a fast-moving world, our company will continue its passionate and unstinting research and development of new industrial solutions tailored to seed, food and grain applications.
