ARTICLE ANNOTATION

quote
This article presents the results of theoretical and experimental studies on determining the mass of lint removed from the surface of cotton seeds in the enlarged working chamber of a linter machine, based on the interaction between the seed agitator and the saw teeth. After the moisture content and impurity level of cotton are brought to the required standards, the fiber is separated from the seeds. Following the ginning process, a relatively short cotton lint remains on the seeds, the amount of which, depending on the breeding and industrial grade of cotton, averages from 11 to 17% of the initial seed mass. In the enlarged working chamber, the delinting process aimed at removing this residual lint from the seeds is carried out through the interaction of the main working elements — the seed agitator and the saw cylinder teeth. Based on theoretical analysis and confirmed by experimental research results, it was established that when the protrusion of the saw cylinder teeth from the working chamber is increased up to 35 mm, the fuzziness (residual lint content) of the delinted seeds decreases to 1.6%. Correspondingly, lint yield increases by up to 0.6%. The study substantiates the necessity of using an enlarged working chamber for the proposed linter machine.
