    <p>Цель исследования – провести экспериментальные исследования кинетики и энергетики предлагаемой технологии выпарки с применением адресной доставки энергии к полярным молекулам с помощью электромагнитных источников энергии СВЧ-диапазона в инновационной выпарной установке. Установлены кинетические зависимости влияния мощности ЭМП, уровня давления, концентрации и вида продукта на удаление влаги и скорость парообразования. Определены динамические параметры при регулировании мощности ЭМП. Обоснована схема предлагаемого вакуум-выпарного аппарата с электромагнитными источниками энергии, при которой получен конечный продукт с концентрацией 90 % сухих веществ. Были проведены экспериментальные исследования на яблочном соке. Исследуемые параметры, влияющие на паропроизводительность установки: влияние давления, удельной мощности электромагнитного поля (ЭМП) и вида продукта. По результатам экспериментов получены зависимости, свидетельствующие, что во время всего процесса скорость выпаривания оставалась постоянной, до конечной концентрации продукта 80–90 %. При этом температура процесса составляет 35–40 °С, что позволяет уменьшить уровень термического воздействия на объект сушки (продукт), это положительно сказывается на качестве и ценности готового продукта, так как позволяет сохранить его биологически активные и термолабильные компоненты, витамины, чего невозможно обеспечить при высоких температурах процесса. Полученные данные свидетельствуют, что при выпаривании пищевых систем возможно перейти от граничных условий третьего рода к условиям второго рода при использовании принципа адресной доставки энергии к полярным молекулам сырья с помощью сверхвысокочастотного (СВЧ) поля. На основании экспериментальных данных предложена критериальная модель, с помощью которой можно точно рассчитать паропроизводительность микроволновой вакуумной выпарной установки. Полученный по предложенной технологии продукт обладает хорошим внешним видом, консистенцией, не имеет постороннего запаха, не подгоревший, что наблюдается в классических выпарных установках. Это приводит к увеличению срока хранения и высокому качеству готового продукта.</p>

    <p>The objective of the study is to experimentally investigate the kinetics and energetics of the proposed evaporation technology using targeted energy delivery to polar molecules using microwave electromagnetic energy sources in an innovative evaporation unit. Kinetic relationships were established for the influence of microwave electromagnetic power, pressure, concentration, and product type on moisture removal and the rate of vaporization. Dynamic parameters for regulating the microwave electromagnetic power were determined. The design of the proposed vacuum evaporator with electromagnetic energy sources was substantiated, yielding a final product with a dry matter concentration of 90 %. Experimental studies were conducted on apple juice. The parameters influencing the unit's vapor productivity were the influence of pressure, specific electromagnetic field (EMF) power, and product type. Based on the experimental results, relationships were obtained indicating that the evaporation rate remained constant throughout the process, up to a final product concentration of 80–90 %. The process temperature is 35–40 °C, which reduces the thermal impact on the drying object (product). This positively impacts the quality and value of the finished product, as it preserves its biologically active and heat-sensitive components, including vitamins, which is impossible to achieve at high process temperatures. The obtained data indicate that during the evaporation of food systems, it is possible to transition from boundary conditions of the third kind to conditions of the second kind using the principle of targeted energy delivery to the polar molecules of the raw material using a microwave field. Based on the experimental data, a criteria model is proposed for accurately calculating the steam capacity of a microwave vacuum evaporator. The product obtained using the proposed technology has a good appearance and consistency, is free of foreign odor, and is not burnt, which is observed in traditional evaporators. This leads to an increased shelf life and high quality of the finished product.</p>
