One of the methods for heat treatment is high-temperature micronization — heating in a flow of infrared radiation. The method is convenient in the conditions of small and medium-sized enterprises. The aim of the study was to obtain the factual material regarding heating and desiccation of hemp seeds when heating in the flow of infrared radiation and modeling of the heating and desiccation processes. The experimental dependences of a seed temperature and moisture on heating time at different regimes of infrared heat treatment were obtained. Mathematical models were proposed for changes in a seed temperature as a function of time and moisture content depending on a seed temperature and the initial moisture. The desiccation models were based on simplified solutions of the system of differentiated equations of heat and mass transfer obtained by academician V. A. Lykov and his students. Model coefficients were identified by the results of the experiments. Analysis of the obtained coefficients shows that it is possible to use one coefficient in the examined models without a significant loss of the prognostic accuracy. The proposed models describe the experimental data quite well upon constant conditions of infrared heating of hemp seeds (irradiance and temperature in the treatment zone). However, heating conditions significantly affect the time dependence of the relative moisture (W/W0) and temperature increment ΔT(t). At the same time, it follows from the processing results and available experimental data that the character of the dependence W(ΔT) is determined by the initial moisture and is stable (that is, weakly depends on heating conditions).</p></abstract><trans-abstract xml:lang="ru"><p>В ряде случаев для снижения влажности, инактивации некоторых ферментов, повышения сохраняемости и эффективности переработки зернопродукты необходимо термообработать. Одним из методов термообработки является высокотемпературная микронизация — нагрев в потоке инфракрасного излучения.</p><p>Метод удобен в условиях малых и средних предприятий. Целью работы являлось получение фактографического материала по нагреву и обезвоживанию семян конопли при нагреве в потоке инфракрасного излучения, а также моделирование процессов нагрева и обезвоживания. Получены экспериментальные зависимости температуры семян и влажности от времени нагрева при различных режимах инфракрасной термообработки. Предложены математические модели изменения температуры семян в функции времени и влагосодержания в зависимости от температуры семян и исходной влажности. Модели обезвоживания основывались на упрощенных решениях системы дифференциальных уравнений тепломассообмена, полученных академиком В. А. Лыковым и его учениками. По результатам экспериментов были идентифицированы коэффициенты моделей. Анализ полученных коэффициентов показал, что в рассмотренных моделях без существенной потери прогностической точности можно ограничиться одним коэффициентом. При постоянных условиях ИК-нагрева семян конопли (облученность и температура в зоне обработки) предложенные модели довольно хорошо подтверждаются экспериментальными данными. Однако на зависимость относительной влажности W/W0 и приращения температуры ΔT(t) от времени существенно влияют условия нагрева. В то же время исходя из результатов обработки и имеющихся экспериментальных данных следует, что характер зависимости W(ΔT) определяется исходной влажностью и является инвариантным к условиям нагрева, т. е. слабо от них зависящим.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>конопляное семя</kwd><kwd>инфракрасный нагрев</kwd><kwd>температура</kwd><kwd>влажность</kwd><kwd>модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hemp seed</kwd><kwd>infrared heating</kwd><kwd>temperature</kwd><kwd>humidity</kwd><kwd>model</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">Зверев, С.В.
