ESM, Established in 1931, were well known in North America and Europe for their versatile range of sorting equipment, not only for rice but also for grading nuts, beans, sesame22 | november - december 2011 After the successful application of optical sorting technology to the domestic Japanese rice market, and having identified its potential for wider exploitation, they acquired the leading US supplier, ESM International Inc of Houston, Texas during 1992. Satake produced their first sorters in Japan in 1979 during a period when a limit on pesticide use imposed by the government had caused an increase in weed contamination of harvested rice and greater discolouration of kernels due to insect activity. In this feature the origins and products of one of the leading suppliers, Satake, are outlined to show how the technology has been developed and applied more widely for its cereal milling and other customers. Consideration can now be given to include optical sorting machines in cereal cleaning plants, whereas they were formerly deemed too sophisticated, unreliable and of low capacity for such applications.

The low cost, reliability and speed of modern components, as in so many consumer and industrial goods, has transformed the design and building of optical processing equipment. Ptical systems, known better as colour sorters, using visible and non-visible wave lengths and once considered as almost exotic equipment, have rapidly advanced to become a mainstream means for separating and grading many industrial and food products including, importantly, cereal grains.
