Problems solved by technology
The heating and drying weighing method is a national standard measurement method with high precision, but the measurement speed is slow. It can only test the moisture content of a small amount of samples and cannot be used for online rapid testing.
Infrared reflectance water measurement method is to use the difference in the reflectance of infrared rays of specific wavelengths for samples with different water contents, and invert the water content of samples by measuring infrared reflectivity, which can be used for online testing, but because infrared rays are mainly reflected on the surface of materials The penetration depth is small, so it is mainly used to measure the water content of the surface layer of the material, and it is difficult to accurately measure the water content of the material body

The invention discloses a method for measuring the moisture by using a microwave technology. The method comprises the following steps: 1) sequentially placing samples onto sample placing tables, then moving along a first sliding rail under the driving of a driving mechanism; 2) after the samples move to a microwave moisture detector, detecting the moisture contents of the samples through the microwave moisture detector; 3) after a microprocessor receives a signal of the microwave moisture detector, processing the signal and comparing the signal with a set value, if a measured value meets a standard, controlling the sample placing tables to continue moving forward along the first sliding rail, and if the measured value does not meet the standard, controlling the sample placing tables to move onto a second sliding rail. By the method for measuring the moisture by the microwave technology, a complete assembly line-type detection system can be formed, not only can continuous sample detection be performed to improve the working efficiency, but also the samples of which the moisture contents do not meet requirements can be automatically sorted out for further moisture treatment.
Description
technical field [0001] The invention relates to a method for measuring moisture, in particular to a method for measuring moisture using microwave technology. Background technique [0002] Most products contain water. Usually the moisture content is not important, but it is necessary to test the moisture content for products that need to be sold and when the moisture content will affect some properties of the product. In industries such as industry, agriculture, and medical care, the moisture content of materials such as building materials, crops, grains, textiles, and medical raw materials needs to be accurately measured and controlled in order to better control product quality. At present, the commonly used methods for measuring the moisture content of materials include heating and drying weighing method, infrared reflectance water measurement method, microwave resonant cavity method, microwave transmission method and so on. The heating and drying weighing method is a nat...
