“…The saw tooth, penetrating into the mass of the seed roller, scrape off the fibrous cover-lint from the surface of the seeds and take it out of the grate [12]. Seeds, as the lint is removed from them and exposed, stand out from the mass of the seed roller and are dropped onto the grate, along which they roll down and are removed from the working chamber [13]. The practice of operating serial 5LP linters shows that the actual performance of a 5LP linter is on average 50% of that stated in the passport.…”

The current state of local and foreign linters has been studied. It has been determined that local 5LP linters when linting cotton seeds do not meet the increased requirements of ginneries in cotton-textile clusters. The practice of operating serial 5LP linters shows that the actual performance of a 5LP linter is on average 50% of that stated in the passport. It was revealed that one of the main reasons for the decrease in the efficiency of the linter is not the perfection of the working body-turner. Due to the imperfection of the agitator design, the density of the seed roller increases, the quality of the lint and seeds deteriorates, and the productivity of the linter decreases. Studies of the Chinese-made MR-160-11C linter operated at the Djuma cotton plant in the Samarkand region showed an increase in the dust content of the air in the workshop due to the absence of a cleaning section for cleaning seeds in the feed system. At the same time, the increase in mechanical damage to seeds by 1.5-2.5% and clogging of the lint by 2.5-3.5% is higher than recommended by the regulations. Due to increased seed damage, these linters were not used to process plant seeds. An increase in the degree of clogging of the lint and an increase in the amount of lint with a short staple length in its composition sharply reduced the quality of the lint. When linting, the productivity of machines for seeds decreased by an average of 50-60%, for linting by 25-35% compared to passport data. To increase productivity and improve the quality of lint and seeds, a new design agitator for the 5LP linter was proposed.

“…The use of this device prevents the addition of fiber, which is the main raw material of the textile industry, to the waste, lint. The amount of fiber output in the enterprise is increased due to the re-ginning of fibrous seeds or letuchka separated in the device and the separation of free fibers [8] [9] [10] [11].…”

The purpose of this research is to improve the qualitative and quantitative indicators of fiber, lint and seeds by improving the technology of preparing cotton seeds for processing. The state of the seeds after the gin was studied and their division into fractions according to the degree of pubescence was recommended, the probabilities of the seeds emerging from the gin with varying degrees of pubescence were investigated, the geometric sizes and shapes of cotton seeds were studied. It has been established that when seeds come out of gin, they have different pubescence. The conditional movement of seeds without separation from the surface has been determined; found a formula describing the movement of seeds without detaching from the surface; the movement of seeds in a micro-flight is determined; the sizes of the cells of the mesh surface were determined as a function of d_c, α and on the speed of seed movement. The aim of the research work is to increase the yield of cotton fiber by improving the processing technology of germinated seeds, to improve the quality indicators of seeds and lint. In order to achieve this goal, a mesh surface device was created to sort the seeds into fractions. Sorting technology was developed on this device and operating modes were determined. In addition, the law of surface distribution of the fractions separated from the cotton stream moving along the surface of the net was determined, and based on the results of practical and theoretical research, a mode of sorting of cotton seeds was developed.
