Annotation

Many researchers at different times have been engaged in drying cereals to preserve their nutritional properties, which is associated with the biochemical properties of materials. The technologies for drying grain crops have been developed and improved with the given recommendations aimed at carrying out the drying process at high temperatures (above 100 ° C). But the increased requirements for seed grains and the associated high energy costs do not allow the drying process to be carried out efficiently, since with large grain volumes this leads to a significant increase in material costs.
The study of the laws of drying of seeds of cereals in view of improving the energy efficiency of the process is relevant. Energy efficiency is one of the main parameters influencing the choice of drying mode. In traditional technologies for drying seed material, it is dried at low temperatures, which does not allow to significantly intensify the process by increasing the temperature of the coolant, as this significantly reduces the quality of the material.
The state of the art makes it possible to more accurately investigate and analyze the drying processes of cereal seeds with automatic processing and plotting of drying kinetics. The results of previous researchers were conducted on existing grain dryers, in which it is difficult to evaluate and give the correct recommendations for drying the seed material. This is due to the peculiarities of the drying process and the design of the grain dryer.
To adequately assess the drying regimes, studies of drying seeds of cereals at low temperatures were carried out to preserve the seed properties of the material. To increase the energy efficiency of the drying process, a step-by-step descending low-temperature drying mode is proposed, which provides the required quality of seed material.
All the proposed technical solutions for the introduction of energy-efficient regimes in the process of drying grain seeds were implemented in the recommendations for industrial drying in mine direct-flow grain dryers.
