“…The specific gravity of raw cotton at normal humidity is approximately 1.3 g/cm 3 . As the fibers are removed from the seeds, their specific gravity increases, since the specific gravity of the seeds is much greater than the fibers.…”

“…Bulk weight, due to the fact that the fiber is removed along with a large layer of air, grows. Thus, sowing pubescent seeds have a bulk weight of about 350 -400 kg/m 3 , ginned seeds 300 -320 kg/m 3 , while 1 m 3 completely bare seeds weigh 560 -600 kg/m 3 .…”

“…In this regard, the tasks for scientists and researchers in the field of primary processing of cotton are set for creation "smart" technologies which can control the quality and quantity of cotton products. In addition, current issues of the present period, there are several issues about separation of cotton fiber from seeds and increase of efficiency of processing of ginned seeds [3] [4] [5] [6] [7].…”

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.

The differential equation, obtained as a result of the theoretical study of the movement of the bare seed on the surface of the grate of the saw gin, made it possible to determine the trajectory of the movement of the seed. The rib is one of the main working bodies of the saw gin. It serves for the free passage of the saw blades through it into the working chamber, for the withdrawal of the fiber caught on the saw teeth after separating it from the seed. A number of studies have been carried out to improve the working elements of the saw gin. The purpose of the research is to create the possibility of timely withdrawal of bare seeds from the working chamber of the saw gin by creating a concavity on the working surface of the grate. The use of the Euler equation for the movement of bare cotton seed along the grate contour, taking into account its speed V, density ρ , pressure P, made it possible to obtain a graph of seed distribution along the grate contour. An experimental 30-saw gin was developed and manufactured, the research carried out on it allowed to determine the rational parameters of new grates, which are recommended for introduction into production. The dependence of the location of the rectilinear part of the general contour on the shape of its convexity and concavity is determined. Based on the above equations, using separate functions, we present the view of the grate profile in the coordinate system modeled on the MAPLE-17 program.
