REDUCING HEAT LOSSES DURING INFRARED DRYING OF RAW COTTON

Abstract

Annotation: This scientific study provides an in-depth analysis of the mechanisms of heat losses and deformation processes observed during the infrared (IR) drying of raw cotton, as well as their impact on energy consumption. The research thoroughly examines the heat-and-mass exchange characteristics of infrared drying technologies, the structural design of the drying chamber, and the spectral parameters of IR emitters. Based on the experimental results, a set of technical and technological solutions aimed at increasing heat efficiency, eliminating sources of excessive heat losses, and optimizing energy use was proposed. The improved approach enhances the penetration depth of infrared rays into the material layer, increases the proportion of useful heat, and improves the intensity of the drying process. Additionally, the optimization of heat distribution, improvement of air exchange systems, and the application of recuperation elements made it possible to reduce heat losses by 25–35% and improve energy efficiency by 15–20% from a scientific and practical standpoint. The outcomes of this study hold significant practical value for the modernization of infrared drying technologies in the cotton industry, efficient resource utilization, and improving industrial productivity.
