Abstract
:The article is devoted to improving the quality of cotton produced by ginners. It has been shown that there is a problem of cleaning and obtaining quality fiber due to the high level of dirt and moisture in the cotton picked on the machine and the fact that the dirt is more strongly bound to the fiber. In the technological processes of the existing ginneries, cleaning equipment is installed that provides the maximum allowable frequency of cleaning, and it is explained that it is not possible to install additional equipment. It has been shown that cotton can be cleaned without additional mechanical action on the fiber, for which cotton can be cleaned in an SBO drying drum, but it is not used in production due to a number of shortcomings.An improved version of the SBO drum has been proposed, which eliminates the shortcomings of this drying drum. Experimental testing of SBO and improved drums was based on the fact that the recommended drum has a high cleaning efficiency, stable performance, the ability to improve the quality class of fiber produced. It was found that the impurities in the passive bond with the fiber are separated, as well as the impurities in the active bond. As a result, a reduction in the amount of fiber deficiencies and impurities was achieved. It was recommended to use an improved drying drum instead of existing dryers.
