The kinetics of the process of drying hot (80°C) and cold (20°C) candied pears were studied. The drying coefficient is found and an analytical dependence is derived for the drying time calculation. Experimental data of the change in the temperature of the thermal agent along with the height of the candied fruit layer was obtained.
The article is devoted to the study of circular economy, its concept; the main circular business- models, their essence and advantages in the practical application based on the analysis of researches of their introduction and use in the world and domestic companies are analyzed; features of the development of circular economy in Ukraine in disclosure of researches of sources of financing of innovative activity and a share of innovative enterprises in general scale are revealed; the expediency of introduction of energy-efficient and energy-saving technologies at the enterprises within the li
The article describes mathematical model of analyses the energy use costs efficiency (depending on the type and volume of products produced by the machine-building enterprise, the consumption of certain types of energy resources and their use in specific production processes, etc.). Methodology and mathematical model of the plan for modernization of industrial production energy-consuming processes has been developed.
Method of eco-energy analysis of household refrigerating appliances based on life cycle GHG emission assessment is presented. New eco-energy efficiency indicator is proposed. Calculation the eco-energy efficiency indicator and traditional energy efficiency index for three household refrigerators has been performed. It was shown the qualitative difference in results of comparison these indicators for analyzed refrigerators.
Water is the only liquid used in human eating which presents different production and transportation processes. All the alimentary liquids, in fact, need production and sanification processes in controlled environments and transportation on carriers. On the other hand, besides more simple production processes, water can rely both on distribution networks and transportation on carriers. In the last years, bottled water consumption greatly increased not only for healthy needs but also for non-essential ones.
The paper suggests the approach to the design of a short-time energy saving reservoir for light-weight electric transport vehicles. It is substantiated that the new product will be energysaving and will ensure gains in traction and braking force. CATIA was chosen as the most proper environment for the design as its libraries are the most suitable for machine-building.
