Students’ Entire Deep Learning Personality Model and Perceived Teachers’ Emotional Support

In recent years, deep learning as the requirement of higher education for students has attracted the attention of many scholars, and previous studies focused on defining deep learning as the deep processing of knowledge of the brain, however, in the process of knowledge processing, the brain not only involves the deep processing of information but also participates in learning consciously and emotionally. Therefore, this research proposed a four-factor model hypothesis for deep learning that includes deep learning investment, deep cognitive-emotional experience, deep information processing, and deep learning meta-cognitive. In addition, the research proposed teachers’ emotional support perceived by students has an effect on the four factors of deep learning. Through SPSS 26 and AMOS 24, this research has verified the four-factor model of deep learning applying exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) and verified that the perceived teacher emotional support has an impact on the four factors of students’ deep learning using the SEM.

DEVELOPMENT AND TESTING OF SOIL IMPURITIES REMOVING APPARATUS FOR POTATO

Aiming at the problem that contain more soil impurities of potato post-harvest, which affects subsequent deep processing, an apparatus for removing soil impurities from potato was developed. The whole structure is mainly composed of frame, feeding port, flexible rubber finger conveying mechanism, slender filament rotary brushing mechanism, discharging port and the like. The research and analysis determined that the main parameters influencing the soil impurities removal performance were the movement speed of conveying mechanism, the movement speed of brushing mechanism and the clearance between conveying mechanism and brushing mechanism (hereinafter referred to as the mechanism clearance). Taking the main influencing parameters as test factors, and the soil impurities removal rate and potato damage rate as indexes, the orthogonal test with three factors and three levels was carried out. The optimal parameter combination was obtained as follows: the movement speed of conveying mechanism was 0.35m/s, the movement speed of brushing mechanism was 0.40m/s, and the mechanism clearance was 55mm. At this time, the average soil impurities removal rate was 87.18%, and the potato average damage rate was 1.95%, which met the requirements of potato cleaning operation.

Deep processing of starch-containing raw materials: current state and prospects for sustainable development

Современные требования инновационной экономики к перерабатывающему сектору сельскохозяйственного сырья должны ориентироваться на безотходные ресурсосберегающие технологии переработки, экологизации производства и природосбережения, в этом и заключается философия технологии глубокой переработки. Только заложив в основу хозяйственной деятельности эти принципы работы, можно обеспечить полное использование всех имеющихся компонентов сельскохозяйственного сырья при минимальном получении вторичных ресурсов и отходов производства и обеспечить устойчивое развитие промышленности. Глубокая переработка зерна кукурузы и пшеницы в России является наиболее перспективным направлением, для этого создана развитая сырьевая база и построены современные заводы по переработке этих видов сырья с производством значительного ассортимента продукции. Разработка и внедрение в промышленность технологий глубокой переработки на основе диверсификации производства с получением широкой номенклатуры продукции является ключевым приоритетом развития крахмалопаточной промышленности России. Необходимость обеспечения развития глубокой переработки зерна обусловлена рядом факторов - это связано с удовлетворением внутреннего спроса на данную продукцию, снижением импортной зависимости от продуктов переработки зерна с высокой добавленной стоимостью, возможностью для выхода на международные рынки в рамках федерального проекта «Экспорт продукции АПК». Последнее десятилетие для крахмалопаточной промышленности было отмечено ростом производственных мощностей, модернизацией действующих предприятий, концентрацией производства, что расширило диверсификацию экономики промышленности и обеспечило хорошую динамику выработки основных видов продукции, повысило ее конкурентоспособность. Комплексное решение стоящих перед промышленностью задач и вывод ее на новый технологический уровень возможны только при разработке целевой программы развития, которая свяжет использование всех видов ресурсов на основе современных достижений научно-технического прогресса и новых форм организации производства. The modern requirements of the innovative economy for the processing sector of agricultural raw materials should focus on waste-free resource-saving technologies for processing, greening production and environmental conservation, this is the philosophy of deep processing technology. Only by laying the foundation for economic activity can these principles of work ensure the full use of all available components of agricultural raw materials with a minimum of secondary resources and production waste and ensure the sustainable development of industry. The deep processing of corn and wheat grains in Russia is the most promising area, for this purpose, a developed raw material base has been created and modern plants for the processing of these raw materials have been built with the production of a significant range of products. The development and introduction into the industry of deep processing technologies based on diversification of production to obtain a wide range of products is a key priority for the development of the Russian starch industry. The need to ensure the development of deep grain processing is due to a number of factors - this is due to the satisfaction of domestic demand for these products, a decrease in import dependence on high-value-added grain processing products, and the possibility of entering international markets under the federal project «Export of agro-industrial products». The last decade for the starch industry was marked by an increase in production capacities, modernization of existing enterprises, a concentration of production, which expanded the diversification of the economy of industry and ensured good dynamics of production of basic types of products, increased its competitiveness. It is possible to comprehensively solve the problems facing industry and bring it to a new technological structure only when developing a targeted development program that will link the use of all types of resources based on modern achievements in scientific and technological progress and new forms of production organization.

Assessment of the technological potential of pacific salmon waste

Обоснованы актуальность и целесообразность комплексной переработки тихоокеанских лососей. Представлены объемы вылова лососевых (горбуши, кеты, нерки и т. д.) за последние пять лет, свидетельствующие о ресурсной достаточности данных объектов промысла. Отмечена потенциальная возможность образования большого количества отходов при глубокой переработке рыбы, которая целесообразна для получения продукции с высокой добавочной стоимостью. Рассчитано количество отходов, образующихся при разделке тихоокеанских лососей на примере горбуши, доля которой от общего объема вылавливаемых лососевых с 2018-го по 2020 год наиболее значительна. Приведен химический состав различных частей тела горбуши, подтверждающий их высокую пищевую, в том числе биологическую, ценность, включая и те части тела, которые условно отнесены к непищевым отходам. Отмечено, что при переработке вторичного сырья, образующегося при глубокой разделке рыбы на потрошеную обезглавленную продукцию или филе, также образуются отходы (например, при производстве пробойной икры). Проведены экспериментальные исследования по определению содержания липидов, белковых и минеральных веществ в отходах от пробивки ястыков горбуши. Установлен их высокий технологический потенциал по содержанию биологически ценных веществ (белков и липидов). По нормам отходов, потерь, выхода готовой продукции и расхода сырья представлены расчеты условного выхода составных частей горбуши в годы максимального и минимального ее вылова за последние 5 лет. На основании рассчитанных данных, с учетом химического состава различных частей тела рыбы (на примере горбуши), осуществлена оценка объема основных пищевых компонентов, биологически ценных веществ в отходах, полученных при глубокой переработке лососевых. Учитывая значительное количество таких отходов даже в год минимального вылова лососевых, сделано заключение о высоком технологическом потенциале всех составных частей тела тихоокеанских лососей и целесообразности использования их для производства биологически ценной пищевой, кормовой и другой продукции. The relevance and feasibility of integrated processing of Pacific salmon is justified. The volumes of salmon catch (gorbuscha, keta, nerka, etc.) over the past five years are presented, indicating the resource sufficiency of these fishing objects. The potential generation of a large amount of waste during deep processing of fish, which is necessary for obtaining products with high added value, was noted. The amount of waste generated during the treatment of Pacific salmon is calculated using the example of humpback, the share of which of the total volume of caught salmon from 2018 to 2020 is most significant. The chemical composition of various parts of the gorbuscha body is given, confirming their high nutritional value, including biological value, including those parts of the body that are conditionally assigned to non-food waste. It is noted that when processing food waste generated during deep cutting of fish into rippled decapitated products or fillets, waste is also generated (for example, in the production of hole caviar). Experimental studies have been carried out to determine the content of lipids, protein and mineral substances in waste from piercing of gorbuscha joints. Their high technological potential for the content of biologically valuable substances (proteins and lipids) has been established. According to the norms of waste, losses, output of finished products and consumption of raw materials, calculations of the conditional output of the humpback components in the years of maximum and minimum catch over the past five years are presented. Based on the calculated data, taking into account the chemical composition of various parts of the fish body (using the example gorbuscha), an estimate of the volume of basic food components, biologically valuable substances in waste obtained during deep processing of salmon was made. Given the significant amount of such waste, even in the year of the minimum salmon catch, it has been concluded that there is a high technological potential of all components of the body of Pacific salmon and that it is advisable to use them for the production of biologically valuable food, fodder and other products.
