Abstract
Purpose. To study the optimization modes of the electric drives of the study of the theory of planning a mathemati-cal experiment under multi factorial influence with oh the search for optimal values of the objective function on the basis of adequate mathematical models in the form of regression equations of the second order; to find operation modes of the follow lines grain cleaning, which in the range of changes in input parameters have provided a minimum of spe-cific energy consumption. The basis of the problem of further improvement of past-harvesting of grain in the conditions of farms is the task of improving the quality of the final product and reducing the energy intensity of the process. Meth-odology. To conduct the research, the theory of the mathematical experiment planning has been used. Results. The cor-responding regression equations of the second order optimization parameters have been received for electricity con-sumption for technological process of grain cleaning in the function of variable factors; performance grain cleaning unit, power consumption and coefficient download electric motors streaming line treatment drain that allowed determin-ing the minimum specific electricity consumption in ZAV-40 cleaning grain unit. Originality. For the first time de-pendencies of specific electricity consumption have been calculated taking into account the actual loading of electric motors which ensure optimization of specific electricity while complying with agro technical requirements for the quali-ty of purified grains. Practical value. The proposed method has allowed to get the lowest possible values unit costs electricity at ZAV-40 cleaning grain streaming lines grain-harvesting unit taking into account the influence of variables. It has allowed develop scientifically grounded norms of specific electricity consumption for technological schemes of grain purification on ZAV-40 unit, which have been discussed and approved by the technical council of the Zaporizhzhia District, Melitopol Regional Department of Agriculture and Velikolepetiskii District Agricultural De-partment of Kherson region.
