Выявлено, что коэффициент удержания масла зависит от величины разряжения в рабочей камере дражировочного аппарата, диаметра экструдированных гранул и продолжительности основных операций технологического процесса, а на величину удельных затрат оказывают существенное влияние содержание жира в экструдированных ранулах, частота вращения лопастных валов дражировочного аппарата и степень заполнения его рабочей камеры. Для оценки значимости влияния исследуемых факторов в результате математической обработки получены регрессионные уравнения, описывающие зависимость коэффициента удержания масла от величины разряжения в рабочей камере дражировочного аппарата, диаметра экструдированных гранул и продолжительности основных операций технологического процесса и величины удельных затрат от содержания жира в экструдированных гранулах, частоты вращения лопастных валов дражировочного аппарата и степени заполнения его рабочей камеры. Адекватность регрессионных уравнений подтверждена уровнем значимости коэффициентов уравнения (p &gt; 0,05) и значением коэффициентов детерминации (R2 &gt; 0,98). Были построены графические зависимости в виде двухпараметрических зависимостей, которые позволили выполнить углубленный анализ поверхности отклика и визуализацию двухфакторного влияния полученных регрессионных моделей. Полученные регрессионные зависимости были использованы в методике инженерного расчета дражировочного аппарата для производства псевдокапсулированных рыбных комбикормов.</p></abstract><trans-abstract xml:lang="en"><p>Research conducted on the development of pseudo-encapsulated compound feed using vacuum deposition of fat components onto the surface of extruded pellets and subsequent application of a protective chitosan coating allowed us to identify the most significant factors influencing oil retention and specific energy consumption. It was found that oil retention depends on the vacuum level in the coating machine's working chamber, the diameter of the extruded pellets, and the duration of the main process steps. Specific energy consumption is significantly affected by the fat content of the extruded pellets, the rotational speed of the coating machine's paddle shafts, and the filling level of the coating machine's working chamber. To assess the significance of the influence of the studied factors, regression equations were obtained because of mathematical processing. These equations describe the dependence of the oil retention coefficient on the vacuum value in the working chamber of the coating machine, the diameter of the extruded granules, and the duration of the main operations of the technological process, as well as the value of specific costs on the fat content in the extruded granules, the rotation frequency of the paddle shafts of the coating machine, and the degree of filling of its working chamber. The adequacy of the regression equations was confirmed by the significance level of the equation coefficients (p &gt; 0.05) and the value of the determination coefficients (R2 &gt; 0.99). Graphic dependencies were constructed in the form of two-parameter dependencies, which allowed for an in-depth analysis of the response surface and visualization of the two-factor influence of the obtained regression models. The obtained regression dependencies were used in the engineering calculation methodology for a coating machine for the production of pseudo-encapsulated fish feed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>математическая модель</kwd><kwd>регрессионные уравнения</kwd><kwd>псевдокапсулирование</kwd><kwd>рыбный комбикорм.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mathematical model</kwd><kwd>regression equations</kwd><kwd>pseudoencapsulation</kwd><kwd>fish feed</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">Абросимова К.С., Абросимова Н.А., Васильева Л.М.
