ТЕОРЕТИЧЕСКИЕ ПРЕДПОСЫЛКИ ОПРЕДЕЛЕНИЯ ФОРМЫ И РАЗМЕРА ОЧАГА РАСПРОСТРАНЕНИЯ ОЗОНА В ЗЕРНОВОМ ВОРОХЕ

Abstract

It is known that at the present stage of development of the agro-industrial complex, the ozonation process is increasingly being used. This is an environmentally friendly method of processing agricultural raw materials in order to disinfect, deodorize, disinsect, increase the growth qualities of seeds, etc. It is worth noting that, despite such an active use of ozone, the question remains not fully understood how the gas spreads in the grain during its processing. The article presents the results of research to determine the shape and size of the source of the ozone-air mixture divergence in the grain heap. It has been experimentally established that the ozone in the grain diverges in a shape close to an ellipsoid. The size of the lesion depends on the saturation time and, as a result, the received dose of ozone treatment. As the duration of the experiment increases, the radius of the ellipsoid increases more than its height. Based on the results of experimental studies in the Matlab program, a model of the behavior of ozone in grain is constructed depending on its processing modes. Using regressions based on Gauss processes, the shape and size of the distribution center of the ozone-air mixture in the grain were predicted with a change in the ozonation time. The selection of model parameters is based on Bayesian optimization in the Regression Learner application from the Statistics and Machine Learning Toolbox of the Matlab application software package. The electronic program allows you to optimize hyperparameters and obtain confidence intervals for predicted values. The research results make it possible to predict the behavior of ozone in grain, which is necessary to determine the number of gas supply nozzles inside a granary of any volume.
