INTRODUCTION
The cotton industry, one of the major manufacturing
industries, is of crucial importance to the economies of
many countries around the world. However, in the
process of producing quality products, this industry
also generates a large amount of waste. One of the
main challenges in the cotton ginning process is the
effective separation of waste and improvement of the
quality of cotton fiber. Incorrect waste sorting can
have a negative impact on the quality of the product,
which in turn reduces the overall quality of textile
products. Various wastes, including cotton husks, fine
fibers and other impurities generated during cotton

processing can significantly reduce the commercial
value of the product. Therefore, technologies for the
effective and rapid separation of this waste are
becoming one of the top priorities of production.
Traditional methods, such as mechanical sorting and
water washing, are often ineffective because they
require a lot of time and resources and have a negative
impact on the environment.
The design of the new cotton separator is aimed not
only at eliminating the shortcomings of existing
technologies, but also at optimizing the use of
aerodynamic properties in the cotton cleaning process.
Conventional separators often suffer from fiber loss,
incomplete waste separation and low energy
efficiency. To overcome these shortcomings, the new
device offers innovative solutions that can significantly
improve the quality of the product. This separator
design is equipped with a high-efficiency aerodynamic
system. Optimization of air flow through perforated
surfaces ensures high accuracy of waste separation
and preserves the natural structure of the cotton fiber.
Literature review
The possibilities of increasing the efficiency of the
cotton
separation
process
by
reducing
the
aerodynamic resistance of the working parts of the
separator are considered.[1]. This study provides a
theoretical basis for the aerodynamic optimization of
separator design and is directly related to the
methodology of this work. Modern technologies for
increasing energy efficiency to ensure environmental
sustainability in cotton processing plants are analyzed
[2]. This article highlights the issues of reducing energy
consumption and minimizing the impact of separators
on the environment. The evaluation of the
effectiveness of new separator designs through
practical tests and the possibility of equipment
modernization are studied [3]. The article presents
technological innovations in the operation of
separators and their impact on production processes.
The ways to increase the speed of the separation
process and solve fiber quality problems due to
automated separator systems are proposed [4]. The
study considers the economic and technological
advantages of separator automation. Mathematical
models used to calculate the aerodynamic parameters
and their impact on the separator efficiency are
described in detail [5]. The mathematical approach is
the main source of separator design improvement. In
the cotton industry, issues of increasing the service life
of separators and reducing costs using new materials
and technologies are considered [6]. The article
analyzes in detail the economic effects of technological
improvement.
The aim of this technology is to reduce waste levels,
minimise fibre losses during cotton ginning and reduce
production costs.
To improve the performance of the cotton gin, a
thorough study of its aerodynamic systems is
necessary. The new separator design is aimed at
maintaining the quality of cotton fiber while
minimizing waste due to perforated surfaces and air
flow management technologies. Therefore, the
research focuses on optimizing the aerodynamic
processes in the internal working chambers of the
separator. Another important aspect of the research is
to improve the energy efficiency of the separator and
ensure environmental sustainability. Conventional
separators are often characterized by high energy
consumption and insufficient waste separation. This
work aims to overcome these shortcomings by
studying the aerodynamic properties of the separator
and the distribution of air flows.

A new experimental design of a cotton separator has
been developed to ensure high efficiency and quality
of cotton. Determining the design structure of the
separator, working elements and technologies that
ensure their joint operation is one of the important
parts of this study. The design of the device is specially
created to ensure a high level of flexibility and
productivity. One of the main working elements of the
separator is a working chamber with a perforated
surface designed to separate cotton from aerodynamic
air flows.

These perforated surfaces are arranged in a spiral,
through which the air flow is distributed evenly. This
design increases the internal pressure of the air flow
and allows for efficient waste separation. The size and
shape of the perforated surface are specially optimized
to protect cotton fibers from damage caused by air
flows. The dryer elements also play an important role
in the device. These elements effectively separate
cotton wool and debris stuck to porous surfaces. The
sliders have a curved shape, are located tangentially to

the shaft and at an angle to the opening surfaces. This
arrangement minimizes damage to cotton fibers and
helps to sort waste as efficiently as possible. The slider
materials are also selected taking into account high
strength and wear resistance.
To evaluate the aerodynamic properties of the
experimental cotton gin, accurate measurements of air
flow speed, pressure forces and other parameters are
required. Modern and high-precision equipment was
used for these measurements. The studies mainly used
such devices as anemometer and micromanometer,
each of which has its own advantages in measuring a
certain parameter. An electronic anemometer was
used to measure air speed. This anemometer allows
you to determine the air flow speed in several units of
measurement (m / s, km / h, ft / s). The electronic
anemometer includes blades mounted on a shaft, a
display and control buttons. Measurements with an
anemometer were simple: after the device was started
and the air flow rotated the blades, the hold button
was pressed and the speed values \u200b\u200bwere
read on the screen. This device also allows you to
graphically track the change in air speed, which
provides a more in-depth analysis of the process.
A special laboratory environment was created for the
experiments, in which it was possible to control the air
flow speed and pressure. The device is connected to
the ventilation system to ensure uniform distribution
of the air flow. The air flow speed was varied from 2 m/s
to 8 m/s, and the separator operation was observed
under different conditions. The force of the air flow
through the internal working chamber and perforated
surfaces was also checked. During the experiments,
the conditions for starting and operating the separator
were separately controlled. After starting the device,
the air flow was drawn into the separator and
distributed over the perforated surfaces. Cotton fibers
were separated by the air flow, and waste
accumulation was observed. The performance of the
device's mesh filters was also assessed, which ensured
undamaged separation of fibers and complete
collection of waste.
RESULTS
The results of the study of air distribution in the
experimental cotton separator confirmed the
efficiency of the separator design. The combined
operation of the perforated surfaces and the air intake
device
ensured
the
optimal
distribution
of
aerodynamic forces. Analysis of the pressure and
speed created in the internal air flows showed the
stability of the processes inside the separator. Uniform
distribution of air pressure inside the separator was
observed using the air suction device. Due to the fact
that the air flow is directed with the same force to the
perforated surfaces, effective separation of waste
occurs. During the studies, it was found that air flows
with a speed of 4-6 m/s have the greatest efficiency. At
these speeds, the degree of waste separation was 95-
97%, which indicated the high efficiency of the
separator.
The spiral arrangement of the perforated surfaces
significantly reduced the aerodynamic resistance.
Smooth air flow and uniform pressure distribution
ensured the separation of cotton fibers without
damage. Also, the compatibility of the air flow tension
with the size of the porous surface increased the
stability of the processes inside the separator. This is
important for the long-term operation of the
separator. Dynamic and static pressure measurements
confirmed the efficiency of air flow distribution in the
working chambers of the separator. The pressure
values measured with a micromanometer allowed the
aerodynamic forces of the separator to be optimized.
When the air flow was directed through the perforated

surfaces, the waste was separated in seconds and it
was observed how the cotton fibers passed through
the cleaning process.
The separator demonstrated a waste separation
efficiency of 95-97%. This figure is due to the uniform
distribution of the air flow and the aerodynamic
properties of the perforated surfaces. During the
experiments, the curved drains and surfaces with spiral
holes used in the separator created optimal conditions
for complete waste separation. This ensured
significantly
higher
efficiency
compared
to
conventional separators. The device also gave high
results in preserving the quality of cotton fiber. The
level of fiber damage during waste separation was
minimal. Large and small cotton waste is evenly
separated, which leads to a significant improvement in
product quality. One of the main advantages of the
device was the effective separation of small particles
between fibers, especially when cleaning cotton. The
separation speed of the separator was also high. When
the air flow passed through the device at a speed of 2-
8 m/s, the waste was separated in a few seconds. This
result helped to increase the efficiency of the
production process. The intensity of the air flow and
the design features of the device ensured high speed
and accuracy of waste separation.
The efficiency of waste separation through porous
surfaces was 95-97%, which confirmed the efficiency of
the separator. According to the measurement results,
the highest efficiency was achieved at an air flow rate
of 4-6 m/s. These parameters were evaluated using
dispersion analysis and it was found that there were no
significant differences between the obtained values,
which indicated the stable operation of the separator.
A statistical analysis of the quality of cotton fiber was
also carried out. According to the results of the study,
the degree of fiber damage was less than 1%, which is a
significant improvement compared to conventional
separators. The correlation between the level of fiber
damage and the efficiency of waste separation was
analyzed, and it was found that there was a positive
correlation between these two variables.
DISCUSSION
The obtained results of the experimental cotton
separator show how much it helps to solve the current
problems of the cotton industry. The results confirmed
that the separator has high efficiency and creates
significant advantages in optimizing the waste
separation process. This device can be considered as an
important tool for the effective modernization of
industrial processes. The results showed that the
separator is able to separate waste with an efficiency
of 95-97% and maintain the quality of cotton fiber. This
helps to solve one of the main problems of cotton
production - incomplete separation of waste and
damage to fibers during operation. While traditional
separators have high losses, this device minimizes fiber
damage and reduces waste.

Figure 2. Installation of the filter in the experimental separator device
The air flow distribution and the aerodynamic
efficiency of the perforated surfaces allowed the
separator to separate waste quickly and accurately.
These results are especially important for cleaning
small cotton particles. As a result, the quality of the
product will increase and the possibility of obtaining
cotton fiber suitable for use in the textile industry will
improve. This, in turn, increases the competitiveness of
the product in the world market. The results also
showed that the separator is environmentally efficient.
The energy efficiency and waste minimization of the
device will serve the sustainable development of the
cotton industry. It reduces the negative impact on the
environment by reducing energy consumption and
limiting the amount of waste. These aspects play an
important role in solving environmental problems in
the cotton industry.
The separator's perforated surfaces are arranged in a
spiral shape, which ensures uniform distribution of the
air flow. This solution protects cotton fibers from
damage and allows for complete separation of waste.
Although in conventional separators some fibers are
lost along with waste, this innovative design minimizes
fiber loss. This helps preserve the natural quality and
productivity of cotton. The device's sieves are located
tangentially to the shaft and at an angle to the
perforated surfaces, such a design allows for effective
separation of waste and preservation of fibers. This
innovative solution significantly improves product
quality and simultaneously increases the speed of
waste sorting. At the same time, the curved shape of
the dampers reduces the aerodynamic resistance of
the device and increases energy efficiency.
The first proposal concerns further optimization of the
device’s porous surfaces. By selecting the size and
location of the holes in accordance with the air flow
and pressure parameters, it is possible to increase the
efficiency of waste separation. It is recommended to
evaluate the separator’s performance under various
conditions by testing the spiral perforated surfaces.
The second proposal is aimed at increasing the energy
efficiency of the separator. Energy consumption can be
further reduced by automating the air flow control. To
this end, it is proposed to equip the device with
intelligent control systems, for example, using sensors
that regulate the air pressure and speed in real time.

This not only increases energy efficiency, but also
ensures the stability of the d
evice’s operation.
CONCLUSION
The results of the research of the new experimental
cotton separator showed that it has great potential in
increasing the efficiency and quality of products in the
cotton industry. Thanks to the innovative design and
technological solutions of the device, the waste
separation process becomes more efficient and allows
preserving the natural quality of cotton fiber.
Experiments confirmed the high efficiency and
competitiveness of the separator. The perforated
surfaces of the device and air flow control technologies
helped to separate cotton waste with an accuracy of
95-97%. This ensured significantly higher results than
traditional separators. At the same time, the level of
fiber damage is minimal, which is important for
improving the quality of the product. These results
practically confirmed the technological advantages of
the device.
The energy efficiency and environmental friendliness
of the device have created additional benefits for the
cotton industry. Optimal air flow control and reduced
aerodynamic resistance have helped to significantly
reduce energy consumption. Also, the speed and
accuracy of the waste separation process contribute to
increased production efficiency. This creates new
opportunities to address environmental issues in the
cotton industry. Some limitations and improvement
suggestions identified during the study serve as
directions for future research. By testing the device in
industrial conditions, studying the possibilities of
working with different types of cotton and increasing
the level of automation, the efficiency of the device can
be further improved. These considerations help to
ensure the universal applicability of the device.
