SYSTEM OF MIXTURE IDENTIFICATION Russian patent published in 2010 - IPC G01N21/35 

FIELD: testing equipment.

SUBSTANCE: invention relates to systems of investigated mixture material identification, when a mixture contains multiple different materials of practically one colour. System of mixture identification for detection of admixture added to tobacco material (T) comprises conveyor (2) for motion of material (T), device (6) for emission of infrared radiation to line (IL) of technical inspection, which is arranged perpendicularly to conveyor (2), device (10) of infrared chamber for reception of infrared radiation reflected from tobacco material (T), which moves perpendicularly to technical inspection line (IL), and generation of output data of (T) material image data, produced on the basis of received infrared radiation; circuit (96) of discriminator for detection of admixture in material (T) based on output data of infrared chamber device (10). Infrared chamber device (10) includes infrared filters (70, 76, 82) for reception of infrared radiation reflected from tobacco material (T) and transmission of infrared radiation only with according lengths of waves, and optical linear sensors (72, 78, 84) for reception of infrared radiation passing through according filters (70, 76, 82).

EFFECT: invention makes it possible to increase speed and accuracy of identification.
