It plays an important role in many industries, helping users to accurately determine the moisture content in a sample, thereby achieving quality control and product improvement. Therefore, an intelligent moisture meter is proposed.

[0003] In the prior art, the moisture content of materials is generally detected by a drying weighing method. However, when drying the materials, most of the materials cannot be stirred effectively, which may cause some of the accumulated materials to be unable to be dried effectively, resulting in a large error in the measured moisture content. In addition, when drying the materials, more steam will be generated. If the steam cannot be discharged, it will condense into water when there is more steam, thereby affecting the drying efficiency.
