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.
This article deals with the problem of studying methods for automatic measurement of electrophysical characteristics of granular materials in the process of technological control using the dielcometric method, based on the interaction of the electric field of the primary transducer with matter. The principle of operation of the information-measuring system is analyzed, the functional scheme of the dielcometric system ispresented with a linear switching of channels, as well as improving the accuracy of measurement by eliminating technical errors, simplifying the measuring scheme and increasing the reliability of the functioning of the entire device.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
