Resumen
En el presente trabajo se realizó un estudio a escala de laboratorio y a escala industrial del proceso de fermentación alcohólica usando mezclas de diferentes sustratos (jugo de los filtros, jugos secundarios y miel final). Para ello se realizó una revisión exhaustiva de la bibliografía, plasmando una serie de aspectos conceptuales relacionados con la temática. Se llevo a cabo un diseño de experimento del tipo enrejado simple. Se determinó valores de % alcohólico, rendimiento, productividad y costos. Los resultados se procesaron estadísticamente aplicando el software STATGRAPHIC, a través del cual se obtuvieron los modelos, el ajuste de ellos y su adecuacidad, permitiéndonos calcular la respuesta para cualquier punto de mezcla prediciendo la superficie completa de respuesta a través del trazado de las curvas correspondientes para cada indicador, así como establecer la mejor proporción de mezcla de los sustratos, las que permitieron definir que las mejores proporciones de mezcla son las que utilizan jugo de los filtros+jugo secundario+miel final, cada uno aportando el 33.3% de ART y la variante que utiliza una mezcla de jugo de los filtros+ miel final cada uno aportando el 50% de ART así como sus zonas de trabajo óptimas.
Presently work was carried out a study to scale of laboratory and industrial scale of the process of alcoholic fermentation using mixtures of different substrates (juice of the filters, secondary juices and final honey). To do that was carried out it an exhaustive revision of the bibliography, capturing a series of conceptual aspects related with the thematic one. You carry out a design of experiment of the simple put bars on type. The results were processed applying the software STATGRAPHIC statistically, through which the models, the adjustment of them and their well as were obtained, allowing us to calculate the answer for any mixture point predicting the complete surface of answer through the layout of the corresponding curves for each indicator, as well as to establish the best proportion in mixture of the substrates. It was determined values of alcoholic%, yield, productivity and costs that allowed to define that the best mixture proportions are those that use juice of the filters +juice secondary +final honey, each one contributing ART'S 33.3% and the variant that it uses a mixture of juice of the filters+ final honey each one contributing ART'S 50% as well as their good work areas.
