Abstract

In Uzbekistan, cotton is a significant agricultural product, serving as raw material for the textile industry and oil factories. Ensuring the quality of cotton fiber and seed is crucial, and this study investigates the factors affecting seed quality during cotton processing. The focus is on the working chamber of the ginning machine, which separates fiber from seed. The study examines the effects of seed comb tooth shape and angle relative to the horizon on seed quality. The research identifies factors causing a decrease in seed quality during ginning and proposes changing the shape of seed comb teeth to mitigate this issue. The study also investigates the effect of seed comb location on seed quality and recommends using seed combs with additional slits to accelerate the exit of fiber-picked seeds from the working chamber. This approach ensures high-quality cotton seed suitable for oil plants and seed planting in fields. The study’s findings contribute to improving cotton processing and ensuring the quality of cotton seed in Uzbekistan.
