One of the longest, energy- and resource-consuming stages of production is vacuum freeze drying. Therefore, in this work we conducted experimental studies on the selection of temperature and time modes of vacuum freeze drying of peptide-based pharmaceuticals. As a result of the experiments, a mode was selected that provides the residual moisture content in the samples not more than 2.5%, no boiling in the first period of drying and minimal shrinkage. Also in the work mathematical modeling of vacuum freeze drying process was carried out using the software package Comsol Multiphysics (calculation of sublimation front motion in a single H5 vial).</p></abstract><trans-abstract xml:lang="ru"><p>Для увеличения количества производимых препаратов на основе пептидов важной задачей является сокращение временных затрат на реализацию технологических стадий. Одной из самых длительных, энерго- и ресурсозатратных стадий производства является вакуумная сублимационная сушка. Поэтому в данной работе были проведены экспериментальные исследования по подбору температурно-временных режимов вакуумной сублимационной сушки лекарственных препаратов на основе пептидов. В результате экспериментов был подобран режим, обеспечивающий содержание остаточной влаги в образцах не более 2.5%, отсутствие вскипания в первом периоде сушки и минимальную усадку. Также в работе проведено математическое моделирование процесса вакуумной сублимационной сушки с использованием программного пакета Comsol Multiphysics (расчет движения фронта сублимации в единичном флаконе H5).</p></trans-abstract><kwd-group xml:lang="en"><kwd>vacuum freeze drying</kwd><kwd>heat and mass transfer</kwd><kwd>drying kinetics</kwd><kwd>computational fluid dynamics modeling</kwd><kwd>drying modes</kwd><kwd>peptides</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вакуумная сублимационная сушка</kwd><kwd>тепло- и массоперенос</kwd><kwd>кинетика сушки</kwd><kwd>моделирование вычислительной гидродинамики</kwd><kwd>режимы сушки</kwd><kwd>пептиды</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Министерства науки и высшего образования Российской Федерации в рамках научной тематики FSSM-2025-0003</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Henninot A., Collins J.C., Nuss J.M.
