Abstract

ORDONEZ, Roger A; HERNANDEZ, Cesar A  and  PEDRAZA, Luis F. Modeling of a Multiple Effect Evaporation System for the Production of Panela (Non-Centrifuged Sugar). Inf. tecnol. [online]. 2012, vol.23, n.6, pp.105-120. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642012000600012.

A method for optimizing processing times and resources in the production of panela, non-centrifuged sugar, with sugar cane juice as the single ingredient. The methodology consisted of modeling a multiple effect evaporation system using experimental data from a real system of three effects that allowed controling the concentration of sugar and the liquid level in each effect. As results, a model system of multiple effect evaporation through a transfer function of third order and a proportional-derivative control were obtained. Finally, it is shown that controling the sugar concentration and the level of liquid in each effect allow to obtain a system of multiple effect evaporation that is more efficient in terms of processing time and optimization of resources.

Keywords : concentration; control; evaporation; panela; thermodynamic; sugar cane.
