“…Upon visual inspection, undissolved water, sludge, suspension and other foreign inclusions must not be visible in the biofuel. Biofuel must be clean, its color can be different, which does not affect its quality [17][18][19]. Usually its flash point is much higher than the same.…”

The research is devoted to solving important tasks of interdisciplinary research work on the topic: «Development of scientific and technical support for energy autonomy of the agro-industrial complex based on environmentally efficient use of agrobiomass for biofuel production», state registration number 0122U000844, implementation of which is planned for 2022–2024 at the expense of the state budget of Ukraine.The use of fossil fuels leads to environmental pollution and climate change in general. To ensure energy security and to improve the environmental conditions necessary for the use of alternative energy sources and to determine their potential impact on the climate and our planet. Looking for more in-depth analysis of all aspects of the use of biofuels in order to determine their potential through the use and economic components.During studies carried out comparing the performance of different fuels. It has been found that the fuel obtained from biomass is advantageous in environmental protection performance in the production process, is absorbed when the biomass in the growth process and the carbon dioxide in operation.Analyzing the following requirements fuel when executed estimate (European) emission standards (CO, ShNu, NO X) for the test cycle, reduced CO2 emissions, the minimum consumption of natural resources and energy, and minimal impact on the environment in its life cycle. There are theoretical ways to increase the effective capacity of machine units and to determine the impact of this increase on the technical, economic and environmental efficiency of a diesel internal combustion engine. It has been found that the use of biofuels from plant oils can reduce the use of fossil fuels and environmental improvements. However, when using a fuel, wherein the content of the organic component exceeds 50%, i.e. deterioration of technical and economic parameters of the diesel engine. Among the mixed fuel we studied the best technical and economic characteristics of a mixture containing 70% of mineral fuels and biofuels 30% rapeseed oil. Thus, the subject to reach a dosage adjustment of the change of the fuel mixture, depending on the speed of rotation of the crankshaft of the engine the best environmental performance.

“…The research focused on an autonomous diesel power source equipped with an SMD-15 diesel engine with a synchronous three-phase current generator GSM-60 (Solona et al 2020). In the course of the research, calculations were performed for diesel engine operation on diesel fuel (Costa et al 2018;Rutkevych et al 2022), BF and their mixes with 25, 50, 75% BF content and with adjustments in the composition of the fuel mix during engine operation (Horbay et al 2018). The criterion for determining the rational composition of the fuel mixture for each engine mode is the duration of the working process, namely the duration of fuel combustion.…”

of working processes in a diesel cylinder, their duration was selected, which is estimated by the duration of the processes of fuel injection, evaporation and combustion. Using the dynamic regulation of the composition of the diesel and biodiesel fuel, the total fuel consumption increased by 5.9%, but the cost of purchasing the fuel is reduced by 10% (at prices as of November 2021) and by 14.6% (based on prices as of the beginning of 2022) compared to engine operation with diesel fuel. This confirms the expediency of using the dynamic adjustment of the composition of the fuel mixture. In addition, even higher economic indicators can be achieved by using an autonomous power plant with a diesel power capacity higher than the generator capacity.

This article is devoted to an overview of modern innovative cleaning technologies used in the food industry. The author reviews various methods of cleaning food products, including mechanical, thermal, and chemical methods. Particular attention is paid to the latest purification technologies, such as membrane technology and ion exchange chromatography technology. The author also explores the possibilities of using nanotechnology in the food industry. One of the innovative cleaning technologies in the food industry is membrane filtration. This technology allows cleaning liquids and solutions from impurities, including bacteria and microorganisms, using membranes with different porosity. Membranes can be made of various materials, such as polymers, ceramics, metals and others. Another technology is ultrasonic cleaning, which is used to clean liquids of dirt, including food particles and microorganisms. During the ultrasonic cleaning process, high-frequency sounds are created in the liquid, which results in the creation of waves that break dirt and microorganisms into small particles that can be easily removed. In addition, innovative cleaning methods such as electrophoresis and photocatalytic cleaning are used in the food industry. Electrophoresis uses an electric field to clean liquids and solutions from impurities. Photocatalytic cleaning uses light and catalysts to clean liquids and air of contaminants. In the modern food industry, innovative cleaning technologies make it possible to improve the quality and safety of food products, reduce cleaning costs and preserve the environment. Such technologies are becoming more and more popular in the food industry and allow to provide consumers The article examines the advantages and disadvantages of each cleaning method, as well as its application in various branches of the food industry. Cleaning processes for various products such as milk, crops and meat are described in detail.
