Outdated technologies in drying processes can lead to iПеrrational use of energy, as a consequence, high energy consumption and increased energy consumption. Therefore, the issues of energy saving and energy efficiency are the most important tasks to be solved. Nowadays, energy saving and energy efficiency are also part of the environmental problem. Ukraine, which has a unique geographical position for Europe, is fully supplied with natural resources, - one of the countries where there is inefficient use of energy resources. One of the energy-consuming areas of vegetable processing is drying. In the modern world, the issue of energy efficiency of drying methods is one of the most relevant areas of research. Convective drying of vegetable raw materials requires a rational use of regime parameters of the process corresponding to the biochemical properties of the processed object. The primary objectives of this area of processing of vegetable raw materials are to reduce energy costs and ensure high quality characteristics of the final product. This article presents the developed heat-technology for obtaining phytoestrogenic powder from soybeans and spinach. Which includes 3 stages: preliminary preparation of raw materials for drying; drying of thermolabile vegetable raw materials; dispersion and packaging of the obtained phytoestrogenic powder. As a result of previously conducted comprehensive research, it was found that the use of heat technology reduces energy costs at the stage of preparation of raw materials through the improvement of existing hydrothermal treatment of soybeans, as well as energy savings of 21% through the use of developed step modes. Studies of the qualitative characteristics of the obtained phytoestrogenic powder confirm the high quality of the final product.

Use Of Resources

Data centers are widely recognized for demanding many energy resources. The greater the computational demand, the greater the use of resources operating together. Consequently, the greater the heat, the greater the need for cooling power, and the greater the energy consumption. In this context, this article aims to report an industrial experience of achieving energy efficiency in a data center through a new layout proposal, reuse of previously existing resources, and air conditioning. We used the primary resource to adopt a cold corridor confinement, the increase of the raised floor’s height, and a better direction of the cold airflow for the aspiration at the servers’ entrance. We reused the three legacy refrigeration machines from the old data center, and no new ones were purchased. In addition to 346 existing devices, 80 new pieces of equipment were added (between servers and network assets) as a load to be cooled. Even with the increase in the amount of equipment, the implementations contributed to energy efficiency compared to the old data center, still reducing approximately 41% of the temperature and, consequently, energy-saving.
