1968 was the year SEA launched on the Italian market the first prototype of optical electronic colour sorting machine for rice.
The success immediately obtained on the Italian market impelled SEA to search for new markets in Europe and to create sorting machines also for other products, ranging from dried fruits to legumes and other foodstuff.
The newly developed technologies allowed to approach in 1989 the recycling industry with the realisation of sorting machines specifically designed for plastic materials and glass cullet.
In 2004 the separator by resonance has collected more and more the favour of the markets explored.
SEA Srl, focusing on the development and production of sorting machines working in monochrome, bychrome, IR, UV, resonance and others, has come to be a fundamental reference point for an increasing number of operators in different production fields all over the world.
