Application of near infrared on-line moisture meter in modern industry and agriculture
- 2020-04-02-

Modern industry and agriculture have certain water content requirements for household products and agricultural harvests. If the water content is too high or too low, it will affect the physical and chemical characteristics and usability of the product, and may even have devastating consequences. For example, excessively high moisture content of textile fibers will result in deterioration of textile shapeability and shrinkage indicators; if the moisture content is too low, it will become brittle and become difficult for the textile, and the textile process will become more difficult (twistability decreases, fiber dust increases, etc.) If the moisture content of the cereal is too high, it will generate heat and mildew during storage; if the moisture content of the cereal is too low, it will also be formed in the storage, transportation, sales, milling and other links.


Therefore, modern industry and agriculture require the control and measurement of the moisture content of the product, including the accurate control of the moisture brought into the production process (such as the moisture content of the paper in the pulp side paper) and the moisture absorbed by the object's hygroscopicity. Laboratory analysis or online real-time monitoring during the production process.


Among various methods of moisture detection, near-infrared online moisture analyzers are commonly used. Tian Weishui molecules have many characteristic absorption fields in the near-infrared region from 0.76 to 6um. Among them, the commonly used and simple absorption peak wavelengths are 0.76 and 0.97. , 1.19, 1.45 and 1.94um. In the near infrared on-line moisture meter detection method, infrared spectroscopic method can also be used, or non-dispersive infrared absorption or infrared scattering method; in the production process, various non-dispersive infrared are commonly used for detection.


Interjet has extensive experience in applying online moisture detection instruments in various industries and a professional service team. Interjet adheres to the fast, reliable and accurate product concept and is committed to bringing domestic testing and control equipment to users. Come better products and more professional services.
