Efficiency analysis of roller squeezing of leather

The study is devoted to the theoretical modeling of the residual moisture in leather, taking into account the phenomenon of its contact interaction with working rolls. Analytical formulas were derived that describe the patterns of changes in moisture content during the process of roller squeezing of leather. A theoretical model of residual moisture in leather during roller squeezing was developed. It was determined that with increasing roll radius and initial thickness of leather, the residual moisture content increases. It was revealed that with an increase in the initial moisture content of leather, its residual moisture content increases and asymptotically approaches a certain value.
