Implementación de un prototipo mecánico de refrigeración mediante placas para la conservación de pieles menores

Abstract

In the facilities of the fur tanning Laboratory of the (ASC), ESPOCH; A refrigeration system was implemented by means of plates for the preservation of the smaller skins, being a work of descriptive type were not considered experimental units, only the equipment was validated using 8 skins of guinea pig and refrigerated rabbit. When designing and constructing a mechanical prototype, the microorganisms that cause putrefaction of the skin are reduced. The efficiency of the cold chamber by plates was 84.62%, wich is high especialy considering that it is national production equipment. The evaluation of the physical resistance of the skins determined the highest result of tensile strenth (1190.64 N/cm2) and lastometry (6,50 mm) in rabbit skins, as well as sensorial ratings (4.50 points), and soft (4.50 points), which have a better cooling performance that skins that are lighter. Byproperly executing the operation and maintenance manuals, you will avoid risks and you will increase the useful life of the equipment. The costs of construction and implementation of the mechanical prototype were $ 2733.92, wich when compared with similar equipment of international origin re very low but without deteriorathing the qualities of the equipment since the tesis validate it, however, labor and materials were used of national production to improve the economy of our country.
