    EN Development of energy-saving technologies and cooling systems for grain storage of small seed cultures
    (2023) Д.Р. Болбас, С.М. Петушенко
    In the modern world, refrigeration equipment systems, in particular, continuous refrigeration chain systems, without which food safety cannot be fully ensured, are becoming more and more popular. Special interest in artificial cooling systems in the grain economy of Ukraine, which is one of the country's bud­get-generating industries. Grain is one of the most important basic human food products, for the cultivation and collection of which large resources are involved. Post-harvest processing and storage is a key link in grain production. According to the Food and Agricultural Organization of the United Nations (FAO), about 20% of harvested grains in the world spoil annually. Reduction of grain losses at all stages of harvesting, transportation, storage and processing and ensuring its preservation is determined by the technology after harvest processing. In the conditions of ever-increasing volumes of grain and high rates of harvesting, the problem of preserving the harvest, more than half of which is harvested in a wet state, is becoming increasingly acute. Freshly harvested wet seed grain is unstable in storage and requires immediate processing. Low-temperature conservation in the places of preparations allows to solve the problem of long-term and high-quality storage of grain products. Small grain varieties due to their small inherent linear size, are most prone to damage during heat drying. Combined compression-absorption water-ammonia refrigerator the machine allows you to abandon the use of mains electrical sources for 7 months of the year. Such a refrigerating machine can be made in a transport autonomous version and solve the task of air conditioning in field conditions. To adapt to field conditions, the ab­sorber is made with two-phase thermosiphons and with air heat removal to the environment
