Разработанная математическая модель, как математическое описание, состоит из уравнений материального, теплового балансов, уравнений гидродинамики в установившемся и неустановившемся состояниях. Данная математическая модель представляет собой основу для создания материальной модели процесса и проведения эксперимента с последующей обработкой данных. В результате можно получить критериальные уравнения процессов, позволяющих сравнительно просто рассчитать процессы при различных технологических режимах.</p></abstract><trans-abstract xml:lang="en"><p>   The subject of the study is the process of active ventilation of wheat grain with variable heat supply.</p><p>   The purpose of the work is a mathematical description of the nature of the flows of matter and energy in the process of active ventilation of wheat grain.</p><p>   Thanks to the selected original design of the exhaust coolant outlet unit, made in the form of a mesh spiral tube, it was possible to optimize the hydrodynamic situation in the layer of dried grain. The developed mathematical model, as a mathematical description, consists of equations of material, thermal balances, equations of hydrodynamics in steady and unsteady states. This mathematical model is the basis for creating a material model of the process and conducting an experiment with subsequent data processing. As a result, it is possible to obtain criteria equations of processes that make it relatively easy to calculate processes under various technological modes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>зерно</kwd><kwd>активное вентилирование</kwd><kwd>математическое моделирование</kwd><kwd>энергозатраты</kwd><kwd>переменный теплоподвод</kwd><kwd>установка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>grain</kwd><kwd>active ventilation</kwd><kwd>mathematical modeling</kwd><kwd>energy consumption</kwd><kwd>variable heat supply</kwd><kwd>installation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бритиков Д.
