Infrared technology has a wide range of applications and development prospects, driving the technological development of various industries. In our life, TV remote control, infrared thermometer are used in this technology. But do you really understand infrared, infrared can solve what problems?

1.Definition of infrared

What is infrared? First of all, let's look at the sunlight, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, gamma rays and several other spectral range. Infrared is between the visible light and microwave electromagnetic waves, is a kind of light invisible to the naked eye.

2.infrared classification and principle

Infrared light can be divided into near-infrared, mid-infrared and far-infrared according to different wavelengths.

Near-infrared uses the principle of reflected light imaging, and is widely used in the field of agricultural inspection and industrial inspection. The middle and far infrared has obvious differences, it is widely used in military reconnaissance and health care field using the principle of thermal imaging, such as infrared thermometer is made using this principle.

3.the applicationof infrared in the color sorting

With the increasing efforts of processing enterprises on quality control, infrared has started to be used in the color sorter industry, and has been increasingly favored in the separation of impurities and quality classification. Among them, the infrared sensor made of InGaAs material, because of the high sensitivity to the material surface moisture content, combined with AI intelligent identification technology, can easily achieve the rejection of all kinds of malignant impurities.

Let's look at a few cases. The rice color sorter produced by GROTECH applies InGaAs infrared technology to the rice industry, solving the problem of impurities such as glass, desiccant, stones and plastic that may be contained in the finished rice, and providing quality assurance for the high-end rice market.

GROTECH produces belt color sorter that utilize visible and multi-band infrared technologies to provide superior solutions for separating nuts with similarly colored shell kernels.

The color sorter industry has been iterating and upgrading with the development of technology, and GROTECH's color sorter has been at the forefront of intelligent sorting technology from the initial color, texture, and shape recognition to already having a multi-spectrum recognition system consisting of visible light, X-ray, ultraviolet, and infrared light.We are always at the forefront of intelligent sorting technology.
