2 118 Mathematical modeling of drying kinetics of sugarcane slices Goyalde et al. INTRODUCTION Drying is one of the most widely used primary methods of food preservation. The objective of drying is the removal of water to the level at which microbial spoilage and deterioration reactions are greatly minimized (Akpinar & Bicer, 2004). In the development and improvement of equipment used for drying, the simulation and attainment of theoretical information about the behavior of each product during water removal is important. For the simulation, which is based on the principle of successive drying of thin layers of the product, a mathematical model that represents, satisfactorily, their water loss during the drying process is used (Berbet et al., 1995). In recent years, various investigators have undertaken studies covering mathematical modeling and kinetics of the vegetable drying process. For example, wheat (Sun & Woods, 1994), bean (Afonso Júnior & Corrêa, 1999), rough rice (Basunia & Abe, 2001), red pepper (Kaymak-ertekin, 2002; Akpinar et al., 2003), pear fruit (Lahsasni et al., 2004), parbolized wheat (Mohapatra & Rao, 2005), and tomato (Sacilik et al., 2006). Considering the fact that Brazil is the principal producer of sugarcane and its importance as an animal food and oil producer, the objective of this work is to fit mathematical models to describe the drying process. MATERIAL AND METHODS The present work was carried out in the Agricultural Engineering Department, located at the Universidade Federal de Viçosa (UFV), Viçosa-MG, Brasil. The sugarcane used for the experiment was taken from Usina Jatiboca, in Rio Casca village, with traditional harvest techniques used for the sugarcane. After harvesting, the sugarcane was sliced with a mechanical machine (Nogueira EM-6400) to 6 mm approximately, and samples were taken for drying tests and initial moisture content. The sugarcane was sliced with moisture content of 70% w.b., measured by applying the gravimetric method at 105 ± 1 ºC for a period of 48 hours in triplicate. The drying tests were performed in an experimental fixed-bed dryer with an upward air flow. The drying was carried out under two air temperatures of 50 and 60ºC controlled by an automatic controller with ± 2 ºC of variation, as Jesus et al. (2001) describes (Figure 1). Figure 1 Dryer view

3 Mathematical modelling of drying kinetics of sugarcane slices Goyalde et al 119 Air relative humidity was 17.9% and 11.1% at temperatures of 50 and 60ºC, respectively, measured with a thermo-hydro clock from Datamed company. The samples used in the experiment were placed in perforated plastic trays inside the dryer. The weight of the original sample was 140 g. A digital scale was used to weigh the samples, model Mark 420LC. The drying was completed when the samples weights were found constant. Then three samples were placed in the oven, model MA033, at 105 ± 1 C for 48 hours to calculate the water content final. The moisture ratio (MR) was determined using the following expression: M M MR = θ M M i e e (1) where: MR: moisture ratio, dimensionless; Mθ: moisture content at time θ (kg water/kg dry mater); M i : initial moisture content, (kg water/kg dry mater); M e : equilibrium moisture content, (kg water/kg dry mater). The equilibrium moisture content for sugarcane was taken from the work done by Rao (2006). The drying curves were adjusted from the experimental data using empiric and semi-empiric models reported in the literature, presented in Table 1 (Madamba et al, 1996; Doymaz, 2004; Mohapatra & Rao, 2005; Akpinar, 2006). Table 1. Mathematical models used to describe the drying kinetics. Model designation Model Henderson and Pabis MR = a exp (-k t ) (1) Logarithmic MR = a exp (-k t ) + c (2) n Midilli MR = a exp (-k t ) + b t (3) n Page MR = exp (-k t ) (4) where: t: Drying time (h); k: empirical coefficients in the drying model ( h -1 ); a, b, c, n: empirical constants in drying model. A regression analysis was performed using the drying mathematical models and the experimental data. The experimental data was interpreted by means of a non-linear regression analysis using the Quasi-Newton method executed with the Statistica 6.0 computer program. The drying models were selected based on the mean relative error (MRE), the standard error of estimate (SEE) and the determination coefficient (R 2 ). The MRE and SEE were calculated for each model by the following expressions (Madamba et al., 1996, Mohapatra & Rao, 2005): where: SEE = ( ) 2 exp pre n i =1 M - M D f n 100 Mexp - M pre MRE = n i =1 M exp n: number of observations; D f : degrees of freedom of the model; M exp : experimental observed values; M pre : estimated values by the model.

RESULTS AND DISCUSSION The calculated determination coefficient (R 2 ), standard error of estimate (SEE) and mean relative error (MRE) for the models presented in Table 1 for 50 and 60ºC are presented in Table 2. All models achieve a R 2 greater than 0.99, which is acceptable according to Madamba et al. (1996), for 50 and 60ºC drying temperatures. The R 2, SEE and MRE values of Midilli model are 0.999, between and 0.010, and between and 7.615, respectively. Therefore, the Midilli model may be assumed to represent the drying behavior of sugarcane slices. Table 2. Statistical analysis for the models using experimental data thin-layer drying of wheat.

5 Mathematical modelling of drying kinetics of sugarcane slices Goyalde et al 121 The time required for sugarcane drying from an initial moisture content of 70% w.b. to the final moisture content of 6% w.b. was 7.5 and 3.5 hours, at temperatures of 50 and 60 o C. Figure 1 verifies that higher temperatures allow for faster evaporation rates.
