Abstract:
2SB-10 drying drum is widely used in cotton ginning enterprises. During the
drying process, a temperature sensor is placed on the drum in order to prevent raw materials from
burning due to high temperature. As a result, regular control of the temperature inside the drum is
achieved. 2SB-10 drying drum is improved and the process is automated.

In order not to lose its natural properties during the storage period of seeded
cotton and to obtain good quality of fiber and seed, it is necessary to dry it in time
and clean it from impurities.
The drying equipment installed in the drying-cleaning departments can be
aerofountain, chamber screw and drum, depending on the method of heat transfer to
seeded cotton. In the cotton cleaning industry, drum drying equipment of various
structures is used, which is considered to be highly efficient in terms of obtaining a
lot of moisture and producing a lot of dried cotton.
Compared to others, tumble dryers have higher drying agent temperatures and
are easier to use.
The heating temperature of its components is of great importance in the drying
of seed cotton. Experiments have determined to what degree it can be heated in order
not to spoil the quality of fiber and seed when drying seeded cotton. When drying

seeded cotton, seed seeds can be heated to 55°C, technical seeds to 70°C, and fiber
to 105°C. If the seeded cotton components are heated above the above-mentioned
temperature, then the germination characteristics of seed seeds, and oil release in
technical seeds, will decrease. The hardness, length and flexibility of the fiber will
decrease. Therefore, seeded cotton should be dried evenly.
Currently, 2SB-10 and SBO drying drums are used to dry seeded cotton in
cotton mills and drying-cleaning departments and cleaning departments in cotton
ginning enterprises. To ensure continuous operation of these drying drums, they are
equipped with heat supply, transport device and supply systems.
Seeded cotton is fed into the drying drum together with heat (drying agent)
using a supplier. Due to the rotation of the drum, seeded cotton rises to a certain
height and is dried due to its mixing with the drying agent. The used drying agent is

The scheme of heat transfer to wet seed cotton during the drying process in
drums is shown in the figure. As shown in the diagram, heat can affect wet cotton in
three ways:

a) Due to the process of mixing with hot air during cotton seeding from drum
shovels;
b) Due to the effect of heat on wet cotton falling between the shovels and on
the shovels through the outer surface of the shovels;
c) Due to the transfer of heat from the heated parts of the drum and the drum to
the seeded cotton [1].
The difference between the improved drying drum model 2SB-10 that we offer
is that a temperature sensor is installed in the drying drum. The temperature sensor
ensures constant measurement of the temperature inside the drying drum. When
drying seed or seeded cotton in a drying drum, the temperature applied to the drum
is
important.

An improved version of this equipment helps us to constantly monitor the
temperature inside the drum, and at the same time to control that the seeded cotton
or seed does not burn from high temperature. We have prevented the loss of raw
materials and the deterioration of the quality of seed cotton.
A thermocouple is a temperature sensing element and a unique device. It
measures the temperature directly and converts the temperature signal into a
thermoelectromotive force signal, which is converted into the ambient temperature
measured by an electrical meter (secondary instrument). The basic principle of
thermocouple temperature measurement is that two conductors of different
components form a closed loop. When there is a temperature gradient at both ends,
current flows through the loop. At the moment, there is a thermoelectromotive force
between the two ends. This is called the Seebeck effect [3].
Conclusion:
As we know, 2SB-10 and SBO drying drums are widely used in
cotton ginning enterprises. Inside the drying drum, seeded cotton or seed is burned.
In order to prevent this, we decided to constantly measure the temperature of the
drying drum. If the improved 2SB-10 drying drum offered by us is applied to cotton
ginning enterprises, the temperature in the drying drum is constantly controlled, and
the loss of raw materials inside the drum does not occur. jobs are saved for the
enterprise. Also, partial automation is achieved in the drying department of the
enterprise.
