Assessment of the accuracy of the thermogravimetric method for measuring humidity and the effectiveness of the application of this method in the agro-industrial complex

Abstract

The problem of limited practical application of methods and devices for automatic control of the moisture content of products of the agro-industrial complex has been studied. Determination of moisture content of products of the agro-industrial complex by thermogravimetric method is considered. The efficiency of weighing and sampling by accelerated and arbitration methods is analyzed. The errors in determining the moisture content of products by the thermogravimetric method are estimated. It was found that the error of the accelerated method is several times higher than the error of the arbitration method. The need to improve the existing thermogravimetric method for determining moisture content, both in terms of rapidity and accuracy, is noted. The importance of choosing the optimal number of determined parameters of the research object, which ensures the maximum measurement accuracy, is shown. Based on the analysis and assessment of the accuracy of the thermogravimetric method for measuring humidity, the main requirements for the design of humidity control devices are formulated.
