The uneven heating of the surface is due to the geometric properties of the radiation source. The work is devoted to the modernization of the heat supply system in infrared drying plants. The object of the study was a vacuum drying unit with a cylindrical chamber. To carry out the research, a software was used to simulate an optical heat supply system using various reflectors. The behavior of the rays and their distribution over the surface of the tray with the product is analyzed. The efficiency of using a parabolic research on drying black currant berries with the use of a designed reflector and without it has been carried out. During the experiments, the heating time of the product was established at various points in the tray. Without a reflector, the time for heating a berry in the center to a given temperature was 41 minutes in the center and 66 minutes in the periphery. Installing the reflector provides more uniform heating over the entire surface of the tray. The difference between the heating time in the center and at the periphery of the tray was no more than 15 %, while in the absence of a reflector this value was 60 %. In addition, the total warm-up time was reduced by increasing the heat flux density due to the installation of a reflector. We also measured the mass fraction of moisture in dry berries at various points in the tray. The results indicate that without a reflector, there is some difference in the mass fraction of moisture in dry berries along the width of the tray. Installing a reflector significantly reduces this difference.","PeriodicalId":148431,"journal":{"name":"Journal International Academy of Refrigeration","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127272072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

В пищевой и фармацевтической промышленности мехатронные пружинные приводы применяются в конвейерных линиях и поворотных столах фасовочно-упаковочного оборудования. Исследованы нелинейные пружинные аккумуляторы с выходным поворотным звеном. Построены математические модели пружинного аккумулятора с предварительным натяжением пружины. Проведен сравнительный анализ пружинных аккумуляторов с выходным поворотным звеном с предварительным натяжением пружины с аккумуляторами без предварительного натяжения. Показано, что увеличение предварительного натяжение приводит к увеличению быстродействия при незначительном увеличении размеров. Кроме того, установлено, что увеличение начальной длины пневматического цилиндра с возвратной пружиной также приводит к увеличению быстродействия. Определены максимальные значения моментов инерции поворотных столов, для каждого типоразмера стандартного пневматического цилиндра с возвратной пружиной, которые могут быть перемещены такими мехатронными приводами при заданном времени поворота в пределах до одной секунды. Разработан мехатронный пружинный привод для поворотных столов фасовочно-упаковочного автомата, с использованием двух пневматических цилиндров, один из которых с возвратной пружиной. Второй цилиндр обеспечивает выход поворотного звена из положения неустойчивого положения, в котором находится система во время технологического выстоя. Даны зависимости для определения диссипативных потерь в элементах пружинного аккумулятора, суммарные значения которых определяют затраты энергии двигателя для компенсации диссипативных потерь.

The aim of the work was to develop buttermilk based fermented milk ice cream. The objects of study were buttermilk obtained from the production of sweet cream butter, fermented buttermilk, and sour milk based on it. The composition and quality indicators of the objects of study were determined by standard methods. To obtain a fermented base for ice cream, buttermilk was fermented with pure cultures of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus. Taking into account the quality of the sour milk clot and the dynamics of acid formation, the Profiline YO 22.11 R2 Golden Line starter culture was chosen to obtain fermented buttermilk. The proportion of fermented buttermilk in the ice cream recipe ranged from 30 to 45 %. An increase in the amount of fermented base increased the overrun of ice cream and its resistance to melting. The results of the studies made it possible to develop a fermented milk ice cream formulation involving the use of 40 % fermented buttermilk. The technology for producing sour-milk ice cream consists of a standard sequence of technological operations and is supplemented by the stages of producing fermented buttermilk. The implementation of an improved scheme for the production of sour milk ice cream will increase the share of the use of a by-product of the dairy industry.","PeriodicalId":148431,"journal":{"name":"Journal International Academy of Refrigeration","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116532408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structure of the equation of state is chosen in accordance with the new representation of the scale hypothesis in the form of an expression for the Helmholtz free energy F = F r + F s , where F r is the regular function of density ρ and temperature T; F s = F s (ρ, T, δ, a (x)) is a singular component F that describes in the asymptotic neighborhood of the critical point the behavior of the equilibrium properties of the liquid in accordance with the scale theory (MT) of critical phenomena. Here δ is the critical index of the critical isotherm; a 0 (x) is the large-scale free-energy function of Kudryavtseva – Rykov, which is developed on the basis of Migdal’s phenomenological theory, the Benedek hypothesis, and the Scofield – Lister – Ho linear model; x is a scale variable. When calculating the individual parameters of the Helmholtz free energy scale function a 0 (x), a similarity theory relation is used, which relates the lattice gas and the real fluid. Based on the proposed method, an equation of state for sulfur hexafluoride has been developed, which, in accordance with MT, describes the behavior of equilibrium properties of the SF 6 . A comparison is made of experimental data, data on isochoric heat capacity and isobaric heat capacity, density values p-ρ-T of saturated steam and saturated liquid with the corresponding data calculated on the basis of the developed FEoS o SF 6 .","PeriodicalId":148431,"journal":{"name":"Journal International Academy of Refrigeration","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116535033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Брайна, Г. Квейта, М. Бэйкура, С. Богданова, а также работ, посвященных исследованию локального теплообмена, таких как Локарта — Мартинелли, Д. Хавла, К. Шарма. Было установлено, что при массовой скорости 50 кг/ (с∙м2), рассмотренные методики расчета средней теплоотдачи удовлетворительно согласуются между собой, что объясняется общностью режимов двухфазных потоков при этой скорости. При скорости 150 кг/ (с∙м2) наблюдается существенное расхождение расчетных данных. При этом методика основанная на использовании истинных параметров фаз и прогнозирования режимов течения дает значения коэффициентов теплоотдачи на 30 % выше других уравнений. Это объясняется тем обстоятельством, что приведенные методы расчета средних коэффициентов теплоотдачи получены в основном для расслоенного и снарядного режимов, а при высоких скоростях имеет место кольцевой режим течения, который известными уравнениями, как правило, не учитывался.
