ENERGY EFFICIENT TECHNOLOGY OF DRYING AND STORAGE OF SEEDS OF GRAIN CROPS WITH THE USE OF HEAT PUMPS
Paziuk Vadym Mykhailovych – Doctor of Technical Sciences, Associate Professor, Leading Research Fellow of the Institute of Technical Thermophysics of the National Academy of Sciences of Ukraine (2 Bulakhovsky St., Building 2, Kyiv, 03164, Ukraine, e-mail: vadim_pazuk@ukr.net )
Energy efficiency of the drying process today is the main parameter that affects the choice of drying mode. Seed requires more careful selection of technology and equipment, which is associated with quality characteristics. Seed material to maintain high germination is dried at low temperatures, the operation of the grain dryer at high temperatures significantly reduces the quality and requires the development of special technology for the production and storage of seeds of cereals.
The article reviews the increase in energy efficiency of equipment for drying grain seeds. Traditional seed drying technologies are too expensive and significantly increase the cost. The developed energy-efficient technologies are more aimed at drying food grain with a process at high temperature, which allows to use the high temperature potential of spent coolant at the outlet of the dryer, which can be recycled and re-directed to heat the drying agent at the dryer.
When drying the seeds of cereals, it is necessary to carry out the process at low temperatures, which reduces the efficiency of the temperature potential of the spent coolant. Therefore, to increase the energy efficiency of the drying process and technology, it is proposed to use heat pumps that ensure the quality of seed material.
The article also analyzes heat losses and recommends measures to reduce losses during drying, which provide for the use of heat pump units.
Energy-efficient technology of drying and storage of seeds of grain crops provides operations of sifting, drying, storage, division into fractions, pickling, packing in bags. A 5-zone grain dryer with step drying modes using a heat pump and a generator motor has been developed for seed grain.
Comparison of energy efficiency of different drying units showed that the proposed technical solutions are verified by calculations and heat consumption is much lower and is 3024 kJ / kg vip . moisture.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production.
During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured.
Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
The journal consistently adheres to the principles of open science. All published materials are distributed under the Creative Commons Attribution 4.0 International License (CC BY 4.0), ensuring open access to research results provided proper attribution to the authors and the original publication is maintained.
At present, Technology, energy, agriculture transport AIC is an authoritative professional scientific journal (Category B), providing a platform for the publication of fundamental and applied research results, promoting the integration of education, science, and industry, and contributing to the advancement of engineering and technological support of the agro-industrial complex of Ukraine.
