Rice quality analyzerIt is a specialized equipment used in the field of grain testing for evaluating rice quality. It can quickly detect key indicators such as amylose content, chalkiness, transparency, and moisture of rice. It is widely used in grain procurement, processing enterprises, and agricultural research institutions, providing data support for rice grading, pricing, and variety improvement.
Its working principle is based on the "optical detection+image analysis" technology: targeting the content of amylose, rice samples are irradiated with near-infrared light of a specific wavelength. Based on the absorption and reflection characteristics of the sample to light, combined with a calibration model, the amylose content is calculated (detection error ≤ 0.5%); When detecting chalkiness, a high-definition camera is used to capture cross-sectional images of rice. Through image recognition algorithms, the proportion of chalkiness areas is calculated to obtain chalkiness (with a detection accuracy of up to 0.1%); The moisture detection adopts a capacitive sensor, which quickly determines the moisture content (detection range of 10% -20%, error ± 0.2%) through the relationship between rice moisture content and capacitance value.
In terms of structural design,Rice quality analyzerEmphasize "efficiency+portability". The device integrates sample preprocessing modules (such as crushing and sample preparation), detection modules, and data processing modules to achieve "one click" detection, with a single sample detection time of ≤ 5 minutes; The display screen adopts a touch screen design, which is intuitive to operate and supports data storage and export (can store more than 1000 sets of data); Some portable models weigh ≤ 5kg, making it easy to conduct on-site inspections (such as grain procurement sites).
In application scenarios, its rapid detection advantage is significant: the grain procurement process is used to quickly determine the quality grade of rice, avoiding the mixing of inferior rice; Processing enterprises use quality monitoring in the production process to ensure stable quality of finished rice products; Agricultural research institutions are used for rice variety breeding, screening excellent varieties with high amylose or low chalkiness. Attention should be paid to operation and maintenance: the sample needs to be treated with impurity removal and crushing (partial indicator testing) to ensure uniformity; Regularly calibrate equipment (recommended once a month) and use standard samples to verify detection accuracy; When cleaning optical components, use specialized lens paper to avoid scratches; When not in use for a long time, it should be stored with power off to prevent moisture and dust.
