Basic Views of Color Sorter
Color sorting is a sorting technology of any bulk materials based on the product analysis by color.
Recently this technology has been recognized by many China manufacturers.
Principle of separating by color was developed already in the middle of the past century,while the first color sorter was installed in
London,1947 by English company Sortex.Currently color sorter of various marks and configurations are produced by a number of
companies all over the world,aiming at cutting edge knowhow in electronics,optics,mechanics and pneumatic.These are high preci-sion machines,being easily operated and making outstanding sorting results up to 99.99% of output product purity.
Color sorting is widely used in food industry,especially where visual product control is demanded,like sorting of cereals,legumes a-nd oil seeds,nuts,grass seeds and even frozen or dried fruits and berries.Color sorters successfully meet the needs of non-food
industries,like recycling of glass and plastic,as well as sorting of wastes,salt and minerals.
Standard procedure of sorter’s operation can be described as follows.
Input material is loaded in the sorter via feed hopper.With the help of vibration the material flows along the chute to the distribution
Then the material gets into the inspection zone “see ①",where it is checked by the high-tech sensors or CCD-cameras.
Cameras,having received the reflected light from the selected material,generate electric signal for computer operating system.
Depending on the signals received from the optical system,the computer control system sends the command to open the pneumatic
valve(the ejector)which blows away grains different in color."see ②"
The good material directly flows into the accepted outlet.The reject is blown off to the rejected outlet.
Most of the sorters have secondary sorting option (Longbow has tertiary sorting option)ensuring more
accurate sorting of the materials and minimizing losses of the good product.
