“Diseño de un proceso industrial para la obtención de alcohol potable a partir de la frutilla (fragaria) para la cervecería nefer”

Abstract

The research objective was to design an industrial process to obtain potable alcohol from strawberry (fragaria). The methodological criterion used was the physical-chemical and microbiological characterization, established in the norms and techniques that are instituted in the manual of procedures of the Technical Analysis Laboratory of the Faculty of Sciences, based on the Technical Norm NTE INEN 3.194 Disinfectant Alcohol, together with the deductive, inductive and experimental methods. Thus, the Process Industry1 was designed to obtain ethanol from strawberry (fragaria) for the Nefer brewery through the processes of disinfection, washing, grinding, filtering, fermentation, distillation and rectification. As a result, Formulation "F3" was the most suitable for industrial production in obtaining potable alcohol of 83º GL, so that each kilogram of fresh fruit pulp, 750/o of sugar and potable water obtained brix degrees and pH within the established range or suitable for fermentation based on the NTE INEN 3194 Standard. It was concluded that the project was viable, with a return on investment of 2 years and 8 months. It is recommended that the residues be dehydrated and used in baking or simply for later use as fertilizer.
