In today's rapidly developing technological era, food testing technology has also undergone revolutionary changes. Portable near-infrared quality analyzer, as an innovative technology, with its portability

Efficiency and accuracy are gradually becoming the new favorites in the field of grain testing. This article will delve into the scientific principles of this technology and reveal how it brings convenience to the grain industry.

Fundamentals of near-infrared spectroscopy technology

Near infrared spectroscopy technology is a non-destructive testing technique that analyzes the absorption characteristics of substances in the near-infrared spectral region (usually referring to the wavelength range of 700-2500 nanometers) to

Obtain chemical and physical information of substances. In grain testing, this technology can be used to analyze the content of components such as water, protein, fat, and starch in grains.

Working principle of portable near-infrared quality analyzer

The core working principle of a portable near-infrared quality analyzer is based on spectral absorption. The device emits near-infrared light of a specific wavelength through a built-in light source, when these rays pass through or reflect

When using grain samples, different components will absorb light of different wavelengths. The spectral data detected by the instrument is then converted into electronic signals and analyzed by built-in software, from

And obtain the quality indicators of grain.

Collection and processing of spectral data

The portable near-infrared quality analyzer is equipped with high-precision optical components and sensors, which can accurately collect spectral data of samples. These data are then transmitted to the analysis software

In the software, the spectral data is converted into specific chemical composition content through a preset algorithm model. These algorithm models are typically based on a large amount of experimental data and chemometrics

The establishment of methods can ensure the accuracy and repeatability of the analysis results.

The advantages of portable devices

Compared with traditional large-scale near-infrared analysis equipment, portable near-infrared quality analyzers have significant advantages. Firstly, its small size and light weight make it easy to carry and on-site

The use greatly improves the flexibility and convenience of detection. Secondly, the user interface is user-friendly, allowing users to quickly get started and even non professionals to easily access food

Quality testing. In addition, portable devices typically have lower energy consumption and maintenance costs, making long-term use more economical.

Application scenarios

Portable near-infrared quality analyzers are widely used in multiple stages such as grain procurement, storage, and processing. In the grain procurement process, it can quickly detect the quality of grain and help

The acquirer makes accurate judgments. In the storage process, it can be used to regularly check the storage status of grain, timely detect and handle problems. In the processing stage, it can help

Enterprises monitor quality changes during grain processing to ensure the quality of final products.

The launch of portable near-infrared quality analyzers not only improves the efficiency and accuracy of grain detection, but also provides strong technical support for the modern management of the grain industry.

With the continuous progress of technology and the deepening of applications, we have reason to believe that portable near-infrared quality analyzers will play an increasingly important role in the future field of grain testing

The role of.

By deeply understanding the scientific principles of portable near-infrared quality analyzers, we can see how this technology has brought revolutionary changes to the grain industry. Diqiang Technology as

The leader of grain testing technology will continue to be committed to developing more innovative products and contributing to food security and quality assurance.
