Study on microwave moisture measurement of grain crops

[摘要] This article discusses the possibility of implementing the microwave method for controlling the moisture content of agro-industrial products, which allows it to be used to control technological processes in grain processing industries and to control materials in free space, converting the parameters of waves passed through the material's wave into an electrical signal. A functional diagram of the developed moisture meter is proposed, on the basis of the method, its electrodynamics' characteristics are determined. Experimental data was obtained for samples of cotton seeds with specified moisture values. A method for measuring grain moisture in continuous production have been proposed, which gives a possibility to reduce the components of the measurement error caused by the uneven distribution of moisture in the grain, the inhomogeneity of the material in terms of density and temperature.
