ANALYSIS OF SCIENTIFIC RESEARCH ON DELINTING TECHNOLOGIES AND TECHNIQUES FOR SEED COTTON
Abstract
Cotton production is a key driver of Uzbekistan's agricultural economy, making seed quality a critical factor in achieving high yields. This paper reviews scientific research on mechanical delinting technologies for seed cotton preparation, focusing on the working principles, chamber design, and operational parameters of delinting machines. The study analyzes the physico-mechanical properties of seed cotton and their influence on delinting efficiency, including the effects of seed layer density, working gap dimensions, and rotational speed on linter separation quality and seed integrity. It is established that seed layer density in the working chamber—ranging from 175 to 550 kg/m³ depending on machine type—directly affects delinting performance and seed damage. The paper discusses the limitations of open-chamber designs with uncontrolled feeding, and identifies the development of a precise feeder-dosing mechanism as a priority for stabilizing seed flow, maintaining optimal layer density, reducing seed damage, improving short linter quality, and lowering energy consumption. The findings contribute to the theoretical and practical basis for improving mechanical delinting machine design.
