Abstract
:The article is devoted to the preparation of cotton for the ginning process, in which the problem of
transferring cotton to ginning for heating is studied. The introduction of pneumatic transport to the cleaning
equipment after the cotton drying drum at the ginning plants and its shortcomings are analyzed. It was found
that the electricity consumed is high and the temperature of cotton decreases sharply as a result of airborne
transmission.As a result of the experiment, the effect of air velocity on the cooling of fibers and seeds was
determined by the nature of changes in their temperature and the decrease in moisture content of cotton. In
order to make effective use of the heat received by the cotton in the drying drum, it was recommended to use
a mechanical conveyor during the transfer to the cleaning.The experiment was based on the fact that when
the cotton is transported on a mechanical conveyor, the temperature drop of the dried fiber is kept to a
minimum and it is allowed to be cleaned when heated. It has been shown that the transfer of cotton to a
mechanical conveyor for cleaning can increase the heat utilization factor for drying by allowing the hot air
leaving the drying drum to be used for additional heating of the cotton. The direction of scientific research to
be carried out in this field was suggested.
