How is NIR Sorting Machine

Near-infrared light refers to the part of the electromagnetic spectrum with a wavelength of 780-2526nm. The absorption of a certain band of light by the vibration of material molecules produces a light absorption spectrum that is different from other material molecules, and the material can be identified by this spectrum. The vibrations of most molecules in the near-infrared spectral region are low-energy electronic transitions, stretching and doubling of frequency and combined absorption of hydrogen-containing atomic groups (such as NH, OH, CH, SH, etc.). This information contains a wealth of features, which is enough to describe common The "fingerprint" of plastic.

NIR Sorting Machine Operational Principle

Material goes through hopper into the machine, shaken by the vibration device, the material slides through distributing box, an then pass through detector and background board. Under the light resource, the light sensor receives compound light from the material, and the system sends out signals, driving the movement of the ejection valve, and remove off color material to the eject chamber. Accepted material freely falls down to the finished-product chamber, so that the material is precisely sorted.

Device Characteristic of NIR Sorting Machine

* Efficiently sort needed material from rejected one.

* Separate various colors;

* Strengthened spout and air jet design for high per-cent contaminated material, durable and dependent;

* Adopts high-resolution image sensor, equipped with high-speed automatic identifying and analysing system;

* New type touch-screen operation platform, big colorful screen and user-friendly operation interface, can easily change sorting precision to the best quality;
