Provision of independent temperature control of heating and cooling agents by a throttle-free heat pump unit with differential heat supply during drying of grain seeds

To ensure the food security of the country, it is necessary to harvest grain seeds annually by agricultural producers. Drying is the most important, energy-intensive and time-consuming post-harvest stage in seed preparation. At present, convective drying with a constant heat supply is the most widespread on the territory of the Russian Federation. To intensify the convective drying process, it is preferable to use the differentiation of heat supply. In order to implement these measures, the possibility of using a heat pump installation of an original design, developed by scientists of the Federal State Budgetary Educational Institution of Higher Education of the State Agrarian University of the Northern Trans-Urals, is presented.
