Implementación de un ablandador de pieles menores para el acabado en seco

Abstract

At the tanning skins laboratory facilities of the Livestock and Cattle Faculty was carried out the construction installation and implementation of the minor skins softener the sampling technique was used which population is the amount of minor skins that are processed and descriptive statistics was applied, to the samplings calculating mean, median, mode and standard deviation. The results of the research indicate that the machine construction for the skin is required because reduce the labor costs, time and price per square foot. The leather softener efficiency was determined according to the costs, time, labor, obtaining an index of 80%, higher value compared with other similar equipment, which efficiency is between 65-75%. In the analysis of softener calibration tests was established for the diameter was registered a media of 38,75 dm?, a humidity of 29,75%, a softness of 4 points, flexion of 3,13 and a fullness of 3,50 points; higher comparing with the characteristics of other leathers. The economic evaluation determined the softener is profitable due to in one year of laboratory work would recover the capital invested and the time remaining of the laboratory useful life is net gain. It is recommended to construct similar machines allowing the automation of the Tanning Skin Laboratory, benefiting to the student-sector directly, giving the necessary tools in order to improve the learning.
