BSTRACT
In the article, experiments were carried out on raw cotton varieties of the An 37 and Namangan 77 breeding
to analyze the operating mode and technological processes of tower drying equipment in the technological
process of drying raw cotton at the cotton ginning enterprise Bahodyr Logon LLC. LLC Textile. From the
obtained results, the amount of moisture removal from the cotton content of the equipment, the time of
splitting of cotton, the amount of consumption for evaporation of 1 kg of moisture from the equipment, and
the results of the analysis are presented.

NTRODUCTION
Several disadvantages of the drum dryers
currently used for drying cotton raw materials,
especially the large consumption of fuel and
electric energy and the violation of the natural
quality indicators of cotton raw materials, i.e. the
reason for cotton wilting [1], have been
determined by experiments. Therefore, in order
to study and analyze the technical and technology

of foreign cotton ginning applied to the cotton
ginning enterprise of "Bahodir Log'on Textile"
LLC in accordance with the reconstruction and
modernization program of the cotton ginning
industry, a number of experiments were
conducted in the cotton ginning enterprise of
"Bahodir Log'on Textile" LLC:
The main part
The experiments were carried out according to a
pre-planned plan. To do this, we analyzed the
samples taken from the machines directly
installed in the production technological process
in laboratory conditions. The experiment was
conducted on the An 37 and Namangan 77
breeding varieties. In the experiment, the
movement of cotton raw material was monitored
directly on the shelves installed in the working
chamber of MGZ 10 tower drying equipment
through special observation windows, and its
movement was carried out by photo observations
[2-4] (Fig. 1).
During the movement of cotton raw materials, the
process of cleaning small impurities in cotton was
observed in pile cleaners installed on the upper
part of the equipment. Raw cotton entering and
leaving the equipment was sampled for moisture
and dirtiness and determined in laboratory
conditions [5-7].

Here: 1- wet cotton drop pipe; 2- observation windows; 3; 4- cotton moving polka dots; 5

observation doors.
The obtained results were filled in special tables (Table 1). As a result of the movement of cotton raw
material on the racks installed on the tower drying equipment with the help of airflow, it was determined
that the time of cotton in the working chamber is 11-13 seconds, depending on the speed of the air in the
working chamber [8-11].

From these obtained results, it can be seen that the moisture separation of the tower dryer is on average
0.8%, and the efficiency of cleaning the passive small impurities in the cotton raw material as a result of
the 2 pile drums installed in the tower equipment is 14.7%. showed that it would.

Here: 1- LKM laboratory equipment; 2- a
sample taken to determine small
impurities in cotton.
In the tower drying equipment, the air movement
without cotton is 26 m/sec on average, and the
time of cotton in the working chamber is 8
seconds on average. This makes it possible to
extract only the free moisture content of the fibre
without completely separating the moisture
content of the cotton. In order to dry low-grade
cotton raw materials, technological processes
require the installation of at least 3 or 4 tower
drying equipment in a row. And this1 kg causes an
increase in the amount of fuel used to evaporate
moisture. as a result of determining the total heat
consumption in the tower drying equipment, it
was found that the F.I.K of the equipment is
17.84%. Oas can be seen from the results, it was
found that the F.I.K of the equipment is very low.
The speed of the air in the working chamber was
determined using cup anemometers and a special
stopwatch.
After the complete removal of cotton in the
working chamber to determine the time of extra
raw material being in the working chamber10 kg
from50 kg was determined by measuring the
amount of cotton at the time of exit by feeding the
cotton to the working chamber.
