Abstract

Various methods of grain moisture measurement are considered in the article. The authors conducted the analysis of the conventional and modern methods of grain moisture measurement used in agriculture and the food industry. The principles of operation and the advantages and disadvantages of each method are described. The article examines in detail the methods used in international standards, and also analyzes the latest methods of grain moisture measurement, such as methods using infrared and microwave technology. The paper proposes a classification of methods for measuring the moisture content of bulk products and identifies the most relevant options for further research. Methods and means of grain moisture control are studied. The work established that the choice of grain moisture measurement method should depend on various factors, such as grain type, measurement accuracy, speed and cost of equipment. The authors analyzed each method in detail and made recommendations for choosing the optimal method of grain moisture measurement for specific conditions. The analysis was carried out and significant parameters affecting grain moisture measurements were selected. A comparison of the characteristics of hygrometers implemented by well-known ultra-high-frequency methods was carried out. The accuracy and errors of moisture measurement of significantly depends on the density of materials and indicators of the measurement medium. The considered hygrometers have high measurement error that does not meet the requirements of certain productions. The comparison of these parameters enabled to determine the optimal method for accurate moisture measurement.
