CORRALES-SUAREZ, Jorge Michel et al. Influence of a Third Set of Knives on the Efficiency of the Sucrose Extraction from Sugar Cane. Ing. invest. y tecnol. [online]. 2015, vol.16, n.4, pp.599-604. ISSN 2594-0732.

The index of cane preparation is one of the variables that influence on efficiency the sucrose extraction process from sugar cane mills in tandem. This influence can be measured by the % sucrose (% Pol) and % humidity in the final bagasse and power demand tandem, these three variables are the dependent variables on this research. The index of cane preparation was the independent variable. The objective of this research is to show the impact of an increased rate of cane preparation, achieved with addition of a third set of knives in tandem, on the efficiency of the extraction process and the tandem power demand. This research was carried out in two stages. A first stage where the tandem was operated with two sets of existing knives and a second stage where it was operated with the addition of a set of knives (that to say with three sets of knives), the third set of knives mounted to increase the rate of cane preparation. A statistical analysis concludes that with increasing the rate of cane preparation both in the final bagasse the % Pol and % Humidity decrease significantly and tandem power demand decreases by 2.87%.
