Details:
Aflatoxin is a metabolite of Aspergillus flavus and Aspergillus parasiticus that grow on food and feed. Almost every kind of food or food product may grow aflatoxin at a certain temperature and humidity. It is widely detected worldwide and mainly exists in various media such as grain, feed, dried fruits, seasonings, oilseed crop seeds.
Optical sorting machine with UV laser technology in sorting aflatoxins
- UV absorption characteristics of aflatoxin:
Aflatoxin has specific spectral absorption characteristics, especially in the ultraviolet (UV) range. UV technology detects the presence of aflatoxin contamination by irradiating the material and utilizing the absorption and fluorescence characteristics of aflatoxin to ultraviolet light. - Fluorescence detection:
Aflatoxin emits fluorescence of a specific wavelength under ultraviolet light. The color sorter irradiates the material with ultraviolet light, detects the emitted fluorescence signal, and then identifies the material containing aflatoxin. - Automated sorting:
The color sorter is usually equipped with a high-resolution optical sensor and a fast-response airflow device. By analyzing the light signal reflected after ultraviolet light irradiation in real time, the color sorter can accurately identify aflatoxin-contaminated particles and sort these particles from normal materials through airflow or mechanical devices.
UV optical sorting machine application
This technology is mainly used in the food processing industry, especially in the following fields:
- Grain processing:
For example, the processing of crops such as corn, peanuts, rice, nuts, etc. can effectively remove particles containing aflatoxin. - Feed industry:
If the feed contains aflatoxin, it will cause harm to animal health. UV color sorting machine can effectively remove these pollutants. - Handling of Nuts and Dried Fruits:
Nuts and dried fruits are easily contaminated by aflatoxin, and UV sorting technology can effectively remove these harmful ingredients.
In short, the UV color sorter has significant advantages in the detection and sorting of aflatoxin and is an effective technology to ensure grain and food safety.
