Based on the analysis of the preliminary modeling results for the cooling process of liquefied methane in straight-flow and counter-flow tubular heat exchangers, a rational variant of cooling liquefied methane for refueling a medium-class carrier rocket, implemented by a straight-flow heat exchanger, was selected from several options. For a more complete assessment of the processes occurring in the heat exchanger during nitrogen cooling of liquefied methane for the selected rational option, an in-depth simulation of the cooling process of liquefied methane was performed. A comparative analysis of the reliability of competing options for fundamental structural diagram of the nitrogen cooling of the liquefied methane, as a result of which the scheme comprising a nitrogen liquefier with centrifugal compressor and turboexpander of low pressure with booster compressor unit, storage and backup tanks with liquid nitrogen, and a ramjet heat exchanger — cooler of liquid methane was chosen as the base option, was carried out. The results of this work can be used in the design of nitrogen cooling systems of liquefied methane for refueling medium-class launch vehicles.

Проведено исследование по совершенствованию технологии сухой клейковины и ее аппаратурного оформления, в которой основной проблемой является не только процесс влагоудаления, а в большей степени процессы подготовки нативной клейковины, как объекта сушки. Представлено эмпирическое исследование гигроскопических характеристик пшеничной клейковины, которые определялись посредством тензометрического метода Ван Бамелена. После реализации серии экспериментов были получены изотермы сорбции влаги клейковиной пшеничной, при температурах воздуха 298 К и 313 К. Математическая обработка экспериментальных данных представлена в виде обобщенной логарифмической зависимости логарифма активности воды от температуры и влагосодержания. Для решения задачи рационального использования энергои материальных ресурсов в технологии производства сухого клейковинного продукта, предложено, для получения объектом сушки сыпучих свойств, реализовать процессы вакуумного самопроизвольного замораживания и последующего подсушивания сырой клейковины до появления на ее поверхности твердой корочки, что существенно повысит эффективность технологии. Экспериментально получено процентное содержание свободной влаги в продукте и конечная влажность, при которой полуфабрикат будет иметь на поверхности сухую корочку, наличие которой минимизирует адгезионное слипание получаемых гранул. Представлены результаты органолептической оценки качества подсушенного полуфабриката, который в случае необходимости обладал бы всеми характеристиками объекта последующего обезвоживания и гранулирования, т. е. заданной хрупкостью. Органолептическими критериями или минимально допустимыми контрольными оценками качества подсушки штранга являлись такие дескрипторы как цвет корки, изменяющийся в процессе подсушки и его внешний вид. Предложенная схема производства является оригинальной и позволит сберечь материальные и энергоресурсы при реализации технологии сухой клейковины. В данной продукции и совершенствовании ее технологии заинтересованы специалисты мукомольной и хлебопекарной промышленности, а также производители макаронных, спиртовых изделий, крахмалопродуктов и др. Ключевые слова: клейковина пшеничная, гигроскопические свойства, глютен, вакуумное замораживание, сушка, влагосодержание, органолептика, профилограмма.

Long-term storage of water is ensured by the inclusion of a device for ultraviolet treatment in the design. Weight and overall characteristics of the container body provide the ability to transport it on the base chassis of a general-purpose truck. The presence of loading and lashing eyes provide the possibility of loading and unloading it, as well as reloading into other types of transport. The results of experimental studies made it possible to develop recommendations for automating the operation of the tank heating system depending on the ambient temperature. The indicators of corrosion resistance and thermal conductivity of the heat-insulating layer have been confirmed.
