Near infrared wheat analyzer: Reshaping grain quality detection

Efficient and precise detection of grain quality is crucial in ensuring food security and enhancing the value of agricultural products. Traditional chemical detection methods are time-consuming, labor-intensive, and sample destructive, making it difficult to meet the efficiency and scale requirements of the modern grain industry. The near-infrared wheat analyzer, with its core advantages of non-destructive, fast, and multi index joint measurement, is becoming a transformative tool in the fields of grain storage, processing, breeding, and scientific research.

Technical principle: The mystery of spectral decoding quality

The core of near-infrared spectroscopy (NIRS) technology lies in the specific absorption of near-infrared light (usually in the wavelength range of 950-1650nm) by substances. When the near-infrared light emitted by the instrument illuminates the wheat sample, the organic molecules in the sample (such as O-H, C-H, N-H and other functional groups) absorb specific wavelengths of light energy. The high-performance monochromator (such as microelectromechanical MEMS wavelength selective type) and detector (such as indium gallium arsenide detector) built into the near-infrared wheat analyzer can accurately capture and analyze these absorption spectral information. By comparing and analyzing with pre established and rigorously calibrated mathematical models (such as specialized databases for wheat gluten, moisture, and protein), the content of key quality indicators can be obtained without loss within seconds.

Analysis of core technological advantages:

1、Excellent precision and stability:

Imported indium gallium arsenide detector: Compared to traditional silicon-based detectors, it has higher sensitivity and signal-to-noise ratio in the near-infrared region (especially>1000nm), accurately capturing weak spectral signals.

High luminous efficiency design: Combining 98% high transmittance with hard low hydroxyl quartz fiber bundle optical path, significantly improves luminous flux, reduces stray light interference, and increases repeatability by 27% in actual testing and analysis.

Strong resistance to environmental interference: The optimized optical system and algorithm improve the ability to resist temperature interference by 15%, ensuring stable and reliable results in a working environment of 5-40 ℃.

Precision optical system: adopting advanced MEMS process technology and military grade micro assembly technology, with wavelength accuracy<1nm, repeatability<0.1nm, baseline stability<0.005AU, long lifespan, and stable performance.

2、Efficient, portable, and intelligent:

Super endurance and lightweight design: High performance and low-power imported battery cells support up to 8 hours of continuous operation, significantly reducing the overall size by 1/3 and weighing less than 8kg (only 256 × 241 × 239mm in size), meeting the needs of multiple scenarios such as laboratories, grain depots, and mobile inspection vehicles.

Intelligent interactive system: a dedicated APP developed based on Linux system and QT architecture, with intuitive operation, powerful self checking function and remote assistance capability, improving user experience and operation efficiency.

3、Professional customized solutions:

Exclusive Wheat Database: Deeply optimized for the core indicators of wheat (moisture, protein, wet gluten), the database motherboard and equipment hardware are seamlessly welded and adjusted, resulting in more accurate and specific model predictions.

Cracking the core pain points of the industry:

Efficiency bottleneck: Instead of time-consuming wet chemical methods such as Kjeldahl nitrogen determination and oven method, single sample detection only takes tens of seconds, greatly improving the flux and efficiency of storage and processing links.

Cost and loss: Non destructive testing avoids sample damage, significantly reduces reagent consumption and labor costs, especially suitable for large-scale, high-frequency testing.

Process control lag: Real time and online monitoring of key quality parameters on the processing line, providing real-time data support for precise wheat matching and process adjustment.

Standardization Challenge: Reduce human operational errors, provide objective and consistent testing results, promote trade fairness and quality control standardization.

Application scenarios and real value:

Grain storage enterprises: Quickly screen the moisture and protein content of wheat at the purchase site, scientifically determine pricing, strictly control the quality of storage, and reduce storage risks. Case: After the application of a large provincial-level reserve warehouse, the storage efficiency increased by 50%, and the mold loss caused by excessive moisture significantly decreased.

Flour and food processing plants: online/near line monitoring of key indicators of raw materials and finished products to achieve precise wheat blending, stable product quality, and optimized raw material costs. Case: A well-known domestic flour enterprise uses online protein detection to improve wheat blending accuracy and increase the qualification rate of high-end specialized flour.

Seed breeding institutions: non-destructive and rapid screening of breeding materials with high protein and high-quality gluten content, accelerating the process of selecting high-quality varieties.

Quality Supervision and Research Institute: Provide efficient tools for market supervision and support scientific research related to grain quality.
