[0002] Grain is important grain crop and processing raw material, and its moisture content is the core index for measuring grain quality, determining its storage stability and commodity value. When the moisture content of grain is too high, it is easy to cause heating, mold and insect phenomenon during storage and transportation, resulting in grain deterioration and serious economic losses. When the moisture content of grain is too low, it will directly affect its eating taste and subsequent processing performance, and reduce the competitiveness of commodities. Therefore, in the whole production chain of grain purchase, transportation, drying, storage and processing trade, grain moisture detection is an indispensable key technical link, which is directly related to the quality of grain circulation and industrial economic benefits.
