Walnuts Infrared Optical Sorter / Walnut optical sorting machines

NIR walnuts color sorter machine can separate kernel from shell even they are same colors .Big capacity with high accuracy with Infrared cameras. 

How to separate the shell from the kernel if they don't have color difference?


InGaAs technology - shell and foreign material removal.HIGHTECH Infrared Walnuts Optical Sorter is the machine with RGB and Infrared function.The machine is designed for the processor who need the highest standard quality and safety.


HIGHTECH Infrared Walnuts Optical Sortercould offer the perfect solution.RGB with InGaAs technology - shell and foreign material removal


Enhanced InGaAs technology can detect defects which cannot be seen in the visible spectrum providing much better separation of good product from foreign material of the same colour. Product modes can be pre-defined for effective shell removal from all types of nuts.

Our Advantages

Based on prism splitting dual-band infrared light spectroscopy technology, it can effectively realize the separation of kernel shells from various nuts such as walnuts, almonds, peach kernels, pine nuts, and hazelnuts.

Perfect integration of visible-infrared composite technology, infrared and visible light are independently set, for black objects that cannot be recognized by infrared, visible light can be eliminated simultaneously.

Equipped with a high-performance halogen lamp constant temperature cooling system, the product stability is higher, and the sorting effect is more stable


InGaAs technology enhancing difficult-to-detect foreign materials

InGaAs technology enhances visibility of defects so the high-definition cameras can detect them. Visibility is enhanced even for those defects that are the same color as good products, such as sclerotia in Walnuts



HIGHTECH provides sophisticated color sorting solutions for nut processors with stringent safety and quality requirement.


Our advanced optical sorting technology delivers superior performance in removing the challenging defects and foreign material from many types of nuts and dried fruit including peanuts,almonds,pistachios,

walnuts,pecans,cashews,pine nuts,hazelnuts,macadamia,Brazil nuts and raisins.


Our intelligent software that analyzes the pre-defined size, shape, and color of your product. It then removes unwanted product that does not meet these parameters. Typical applications include removing undersized, oversized, and broken particles
