The modern development of the food industry is accompanied by an increasing use of automated process control systems. The widespread use of automated control systems is caused by a significant economic effect, which is achieved by ensuring the specified qualities of the products produced regardless of subjective factors, reducing the loss of valuable products, reducing the labor intensity of production processes, and increasing the culture of production. The article presents a scheme of automation and energy saving of the technological process of production of functional beverages based on direct-pressed grape juice with increased nutritional and biological value due to the inclusion of feijoa and blackberry extracts in their composition. Monitoring of the technological process was carried out using a multi-channel stand. The main parameters of monitoring were the consumption of basic and auxiliary products; the temperature of pasteurization and cooling of direct-pressed juice and extracts from fruit and berry raw materials; the level of pulp and product in the tanks. The obtained experimental data and developed technological methods allowed us to offer an effective energy-saving technology for the production of high-quality functional beverages in the conditions of energy-saving management of the production process. To implement the proposed technology, a hardware and technological scheme for the production of functional beverages has been developed. Process monitoring allows you to reduce energy consumption by up to 30% by using modern automation and control tools.

The modern development of the food industry is accompanied by an ever wider application of automated control systems for technological processes. The prerequisites for this are: the growth of the enterprise's capacities; the use of continuous and continuous production methods; equipment of enterprises with new high-performance equipment; presence of modern technological means of automation. The wide application of automated control systems is caused by a significant economic effect, which is achieved due to: the provision of specified qualities of produced products, regardless of subjective factors; reduction of losses of valuable products; reduction of labor intensity of production processes; increase of production culture. The main task of the automated control system is the observance of the technological regulations determining the permissible ranges of technological process parameters (temperature, flow, product composition), equipment performance, and quality process indicators. In addition, the tasks of controlling installations and lines include their starting and stopping, emergency protection and interlocking. In order to carry out the tasks of automated control of installations and technological lines, it is necessary to gradually remove the human operator from the control loop and transfer the control functions to the technological means of automation. At the same time, the operator must monitor the operation of automation devices and make decisions in complex situations. Modern sugar production is a complex technological process. Therefore, ensuring the uninterrupted operation of the production line, maintaining its high productivity, obtaining a product of the highest quality is the most urgent task in this area.

Производство напитков функционального назначения в настоящее время имеет актуальное значение, при этом наиболее перспективными являются напитки, приготовленные на основе натуральных соков с добавлением ингредиентов, выделенных из растительного сырья, в том числе из плодово-ягодного. Помимо органических кислот, аминокислот, витаминов, пектиновых веществ, полифенолов и природных углеводов, эти напитки насыщены также дефицитными микронутриентами, оказывающими позитивное действие на состояние человеческого организма. В статье представлены результаты исследований по разработке рецептур и технологии производства высококачественных функциональных напитков на основе виноградного сока прямого отжима, обладающих улучшенными потребительскими свойствами за счет включения в их состав экстрактов плодово-ягодного сырья - фейхоа, ежевики и черной смородины. Приведена оценка показателей качества и безопасности разработанных напитков и процессуально-технологическая схема их производства. Работа выполнена на базе учебно-научной лаборатории технологии виноделия и продуктов питания из растительного сырья Ставропольского ГАУ. Для определения физико-химических показателей и пищевой ценности сырья, полупродуктов и приготовленных функциональных напитков применяли современные общепринятые методы исследований согласно действующих ГОСТ. Разработка технологии производства напитков на основе виноградного сока с применением плодово-ягодных экстрактов является особенно важной и актуальной задачей в связи с наличием разнообразной и доступной сырьевой базы на Юге России, а также высокой концентрацией в данном регионе плодоперерабатывающих производств, оснащенных современным высокопроизводительным оборудованием. Полученные нами результаты могут способствовать целенаправленному применению разработанных напитков в санаторно-курортном лечении населения для решения проблемы оптимизации питания и повышения пищевого статуса населения России. The production of functional beverages is currently of urgent importance, while the most promising are drinks prepared on the basis of natural juices with the addition of ingredients extracted from vegetable raw materials, including fruit and berry. In addition to organic acids, amino acids, vitamins, pectin substances, polyphenols and natural carbohydrates, these drinks are also saturated with scarce micronutrients that have a positive effect on the state of the human body. The article presents the results of research on the development of recipes and technology for the production of high-quality functional beverages based on direct-pressed grape juice, which have improved consumer properties due to the inclusion of extracts of fruit and berry raw materials - feijoa, blackberry and black currant in their composition. The evaluation of quality and safety indicators of the developed beverages and procedural and technological scheme of their production is given. The work was carried out on the basis of the educational and scientific laboratory of winemaking technology and food products from vegetable raw materials of the Stavropol State Agrarian University. To determine physicochemical parameters and nutritional value of raw materials, intermediates and prepared functional beverages, modern generally accepted research methods were used in accordance with the current GOST. The development of technology for the production of beverages based on grape juice using fruit and berry extracts is a particularly important and urgent task due to the presence of a diverse and affordable raw material base in the South of Russia, as well as a high concentration of fruit processing plants accomplished by modern high-performance equipment in this region. The results obtained by us can contribute to the purposeful use of the developed beverages in sanatorium treatment of the population to solve the problem of optimizing the nutrition and improving the nutritional status of the population of Russia.

The purpose of this article is study and identification of the most promising trends and engineering solutions in order to improve resource saving and energy efficiency in the production of corundum on the basis of the conducted patent review on melting improvement and optimization. The ways to optimize the corundum production are considered in three directions from the point of view of energy saving. The first direction relates to the development of promising engineering developments. The latter are studied to select rational operating modes and determine the main factors affecting voltage surges during the technological process and useful product yield. Consideration is given to the conditions for reducing specific energy consumption and improvement of production environmental friendliness at all stages beginning from isothermal sintering of corundum, production of electrocorundum, fine corundum to single corundum crystals. The second direction is the optimization of corundum production at all stages for the development of an optimal control algorithm for the technological process. In this case the electricity consumption might be reduced by 10-12% as compared to current standards. The third direction is the development of engineering solutions involving the change of individual structural units of furnaces, namely, the use of modern components and new heat insulating materials, as well as the application of spent heat carriers as the sources of secondary energy resources and the introduction of additional controllers of the automated control system of the process. The analytical study has shown that the result of optimization should be upgraded designs of plants and electrical equipment, which can provide maximum electrochemical efficiency, and corresponding furnace tightness. Criteria for energy supply and energy quality making possible to stabilize furnace material balance and solve resource saving issues have been developed. These measures allow to reduce the loss of raw materials up to 20-25%, the specific energy consumption under the production of corundum by 2-3 thousand kWh per 1 t.

Quality of the automatic control is the basis of economic effect of industrial control systems. The appropriate regulator settings should be found to improve the quality of automated control systems, but improved accuracy results in the reduction of stability margin, that’s why operators try to reduce setttings in complex systems (ie, set the "weak setting"),so the system could worke in all modes. Controller’s "low (all-mode) tuning" is the main disadvantage of existing control systems, which reduces profits. Frequent changes of plant parameters are the prime cause of low quality tuning and reduced efficiency of control systems. These changes are caused by changeable mode of plants, loop interdependence in multidimensional systems. In terms of operating the only one way is to ease settings, achieving reduction of loop interdependence, ensuring adequate stability margin in all possible modes of operation. The quality of work with such tuning is obviously worse and the profit is less. The article presents possible approaches that can increase the efficiency of automatic control systems and describes the adaptation algorithm for PI controller based on an analysis of statistical data.
