Simulation of the process of cotton drying under the influence of a heat agent in a spiked - screw cleaner

The spiked-screw cleaner was divided into several sections, and taking into account the same amount of cotton in all sections at the same time, the drying process of cotton in each section was studied from a theoretical point of view. A drying agent was supplied from the upper side of each section, and the process of heat exchange with the cotton rotating and advancing in the spiked-screw was studied. In this case, equations were obtained that indicate that the level of small impurities released from cotton depends on the temperature of the cotton when hitting the heated cotton with piles in each section of the cleaner, moving it on the mesh surface and throwing the cotton up. It was found that the change of the temperature of the cotton fiber depending on the number of sections n and the air temperature in the open part of the surface T 1 (K) depending on the screw angle θ is close to the law of change of the cotton fiber on a straight line. It was found that the process of moisture exchange in its components depends on the effect of hot air and the drying mode when extracting moisture from cotton moving in a pile-screw cleaner.
