In the field of grain storage and processing, the freshness of rice directly affects the quality and market price of rice. Traditional manual sensory identification methods are not only inefficient but also susceptible to subjective factors. However, rice freshness testers, leveraging aldehyde and ketone detection technology and intelligent operating systems, provide a scientific and efficient solution for grain depots, processing enterprises, and quality inspection centers.

Technical principle of rice freshness tester

Based on the amount of aldehydes and ketones produced during the aging process of rice samples, the rice to be tested is ground into rice grains. After adding a special reagent, the rice sample is mixed and centrifuged. By detecting the color change of the mixed solution after the reaction between the sample and the reagent, and after instrument detection, the freshness value of the sample is displayed to determine the freshness level of the rice sample.

Technical highlights:

Light source consistency: Precision rotating device ensures consistency of light sources across 12 channels;

Environmentally friendly design: Waste liquid can be directly discharged into the sewer, avoiding secondary pollution.

Performance advantages of rice freshness analyzer

1. Efficient batch detection:

With 12 independent detection channels, 12 samples can be tested in 1 minute, enhancing detection efficiency;

Equipped with a built-in thermal printer, the results are automatically generated into labels, meeting the management needs of grain depot sub-warehouse division.

2. Intelligent data management:

The Android 7.1 system supports touch operation, boasts a user-friendly interface, and enables novices to get started in just 3 minutes;

WiFi/Bluetooth/U-disk three-mode transmission, real-time data upload to cloud platform, supporting long-term traceability analysis.

3. Adaptation to harsh environments:

Operating temperature: 18-25℃, humidity: ≤80%, suitable for complex environments such as grain depots and processing plants;

With an AC 200-240V wide voltage design, it is widely applicable.

Application scenarios of rice freshness tester

Grain depot management: Regularly inspect reserve grains to avoid the mixing of "aged grains";

Processing enterprises: Raw materials are tested upon arrival at the factory to ensure stable rice quality;

Quality Inspection Center: Quickly screen the circulating rice in the market and crack down on the chaos of "substituting old for new";

Research institution: Study the aging mechanism of rice and optimize grain storage technology.

The rice freshness tester has become a quality inspection tool in the grain industry due to its fast, accurate, and intelligent characteristics. Whether it is storage management or processing quality control, the rice freshness tester can provide scientific data support, helping enterprises reduce costs and increase efficiency!
