This article analyzes the structural solutions, energy efficiency, and technological capabilities of existing dryers used for agricultural products, in particular for drying grain and paddy rice. Conventional drying methods are considered the main problem due to their high energy consumption, contamination of the product with exhaust gases, and negative impact on grain quality. Based on this, an energy-saving and environmentally safe combined rotary dryer design is proposed.

In the design process of the dryer, special attention is paid to the efficient use of solar energy, removal of the initial moisture content of the grain by means of a pneumatic dryer, and improvement of grain mixing inside the drum.
