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.

Satake / ESM have always been at the forefront of developing machines to suit their customers’ needs. Satake optical sorting technological advancements since the 1980’s have included bichromatic; high-resolution CCD cameras; infrared; shape and length detection; chlorophyll fluorescence; UV; RGB  full colour sorting; long lasting LED lighting and MIR multi-wavelength technology. 

As one of the world’s leading manufacturers of optical sorting equipment Satake has been responsible for many innovative solutions and processes which are now considered industry standard.
