Influência da matéria estranha total sobre a eficiência geral industrial e teórica da fermentação na produção de cachaça.

Abstract

The search for renewable energy sources is increasing every year, so various technologies in new biofuels are being improved, no different with ethanol and other sugarcane derivatives, the increase in ethanol and cachaça production, ends up increasing production. sugarcane production, and with the increase in sugarcane production occurs the increase of foreign matter (MET). Foreign matter is everything that enters the production process, which does not stalk, foreign matter has two distinct origins, it can be of mineral origin, or vegetable origin, the work developed aims to investigate the impacts that foreign matter may have on the production of ethanol and cachaça, the way out to reduce foreign matter is the burning of sugarcane straw, but in the last years stricter environmental legislation, make this practice difficult, the way out for such problematic proposed by companies that develop harvesting equipment, developed harvesters that promise clean sugarcane, this is not really the case, plant foreign matter has been increasing long after the advent of mechanized harvesting. We know that foreign matter adds to the wort contamination, non-fermentable sugars, color, among others. On the other hand, the straw that comes with the cane ends up stealing sucrose that would be transformed into sugar or ethanol. The present work was developed searching data to establish a relationship between the percentage of MET and the general industrial and theoretical fermentation efficiencies on the production of cachaça and brandy. Polynomial regression graphs were adopted and the linear correlations between the MET and the efficiencies were estimated, which described the relevant antagonistic influence of the former on the latter. The MET when coming from mineral output of the industrial plant has an influence of up to -62% on the theoretical fermentation efficiency and -10.7% on the overall industrial efficiency which means that the MET impacts not only on fermentation, but in every industrial process. This was a quantitative study of fourteen days within the production process of a cachaça and brandy production plant in Paraíba. The study showed that plant impurities impact industrial efficiencies much more than mineral impurities. Strengthening the importance of the routine work of raw material analysis, in terms of plant impurities, for decision making in industrial management.
