Abstract

The article is concerned with energy conservation in the process of cleaning grain. The study aimed to find ways of reducing energy consumption when cleaning food grains by using energy-saving operating modes (ESOM) on the production lines of grain storage facilities. For this purpose, experimental tests were performed which involved studying the effects of physical and chemical properties of grain as well as the influence of various operating modes of the production lines on the specific energy consumption (SEC), which was found to be the most informative indicator for determining ESOM. The mathematical description of the target function was carried out by conducting a multifactorial experiment with the application of the orthogonal central composite design (OCCD) of the second order. Calculations produced a number of mathematical models describing the dependence of the response function on the input parameters. The proposed approach made it possible to obtain the minimum SEC for cleaning food grains and to develop practical recommendations for ways to reduce energy consumption, which resulted in the development of scientifically based SEC standards for a grain cleaning machine.

Highlights

The problem of energy conservation, which is extremely urgent globally today, is acute for Ukraine, as it is capable of meeting only 35–40% of energy needs using its own resources
The issue of optimizing the process of cleaning food grains on the production lines of grain dispensers is to find such modes of operation of the grain cleaning production lines, which result in the minimum specific energy consumption (SEC) within the range of changes of input parameters
The theory and practice of its design are characterized by a high level of development and make it possible to obtain, with a minimum number of tests, a credible mathematical model of the object of the research and, in solving the problem of optimization, to determine the optimal conditions of its functioning

Summary

Introduction

The problem of energy conservation, which is extremely urgent globally today, is acute for Ukraine, as it is capable of meeting only 35–40% of energy needs using its own resources. For this reason, energy conservation is a challenging issue that requires the attention of researchers [1,2,3]. The aim of the study is to determine whether it is possible to reduce energy consumption while cleaning food grains on the production lines of grain storage facilities by using ESOM of the electrical equipment. The SEC while grain cleaning proved to be the most informative indicator for determining ESOM [11]
