NIR Color Sorter--NIR Sorting

NIR Infrared colour sorting machine including color LED photo system and near infrared spectrum lighting system color LED lighting system can choose different spectral illuminations according to different raw materials, to increase the contrast ratio of main features, in order to ensure the obtained material information is more precise. The LED lighting system with heat dissipation has long service life, low energy consumption and good performances.

  • Description

What can NIR color sorter do ?

HT NIR color sorter including RGB color sorting technology with RGB camera image analysis, and is ideally suited to sort wrinkled skin beans ,wormhole beans ,nuts,grain etc . It also features  size and shape sorting to help remove the un-wanted product, or reject material of the exact similar color but of different size. The NIR colour sorting machine can also be equipped with the latest InGaAs near infrared (NIR) cameras to identify impurities like metal ,wooden,glass, plastic, stones, sticks etc.

It is suitable for the sorting of various malignant impurities in materials, and has exclusive .non-destructive testing capabilities for empty fruit, atrophied fruit,and wormhole damage in nut products.Comprehensively improve the ability ofNIR fluoroscopy and material shape selection, color selection and malignant impurities sorting.

It is suitable for the sorting of various malignant impurities in materials and the sorting ofhomogeneous characteristics, and realizes the identification of materials from multiple dimension and characteristics such as color,shape, texture, area, light and shade, light and heavy,soft and hard.

Advantage with NIR Infrared Color Sorter


A. Wide range of application:In addition to realize colour sorting by visible color spectrum system, also can realize the sorting of infrared sensitive material by using near infrared optical system.

B: Combine shape sorting function:According to the characteristic of material, using special image processing algorithm with shape and color, to realize shape sorting successfully by detecting material's Circularity rate, linear rate, Perimeter and area, etc.

C: Transmission-type color tunable background lamp:Use transmission-type background board instead of traditional reflection-type background board, simplified the system, improved the stability. Use RGB color tunable background lamp instead of RGB reflection board, in addition to get red, green, blue color, also can get multi colors by the mixing of RGB lights.widely expanded the colors of background.
