Abstract—The results of experimental studies are presented in the paper by determining the effect of the amount of water extracted from the leather semi-finished products under their simultaneous squeezing between rotating working rollers. A mathematical dependence of the amount of squeezed out water from wet leather semi-finished products under various pressures of the working rollers and the feed rate on the number of layers of leather semi-finished product with monshons was obtained. To increase the productivity of moisture extraction from wet leather semi-finished products of chrome tanning, the technological process was conducted by folding several layers of wet leather semi-finished products onto the base plate, between which moisture-extracting materials of the LASCH brand were pre-laid. According to the proposed method, the base plate with a folded package of wet leather semi-finished products and moisture-extracting materials is pulled in the vertical direction by means of traction chains between rotating squeezing rollers arranged horizontally. By increasing the number of simultaneous feeding of layers of semi-finished leather and increasing the pressing force of the squeezing rollers, the efficiency of the technological process is increased, which in general contributes to significant savings in energy consumption and labor costs. Based on the results of the experiment and their mathematical processing, a mathematical model was obtained to extract water from wet leather semi-finished products after chrome tanning, depending on the pressing force of the squeezing rollers and the feed rate. The proposed method to conduct the technological process of moisture extraction can be used by designers of new technological machines to remove moisture from various materials, for example, in the textile, pulp and paper industries.
