The first optical sorters were developed in the 1930’s by ESM a forerunner of Satake. As the technology and applications continued to develop, colour sorters steadily gained in popularity with pulse, nut and coffee processors worldwide through the 1940’s and 1950’s. The 1970s and 1980s saw substantial growth within the Japanese rice industry in the when demand for high quality rice increased.
