This study presents the development and analysis of a resource-efficient, small-sized drum dryer with a chain drive, tailored for cotton processing. A chain transmission system was selected with calculations determining the forces on support rollers, torque, and power requirements for drum rotation. The experimental dryer was designed with reduced dimensions, offering enhanced energy efficiency and improved drying performance. Experimental data reveal that the duration of raw cotton in the drum dryer is primarily influenced by rotational speed rather than productivity levels. Increasing rotational speed reduces drying time, enhancing process efficiency without compromising cotton quality. The chain-driven system proved effective, showcasing reliable operation, reduced energy consumption, and minimized environmental impact. The findings contribute to sustainable drying technologies in cotton production, emphasizing the importance of optimized mechanical designs and operational parameters.
