| Opuntia ficus-indica, also known as nopal, is a cactus which grows on arid and semiarid lands of America. Dehydrated nopal is an alternative for food preservation, but drying times of cladodes are very long. The objective of this study was to evaluate dry kinetics of nopal thin slices, of 4 mm thick, 140 mm long and 17 mm wide. We conducted the drying process in a convective cross flow tray dryer at 35 °C, 45 °C and 60 °C and air velocities of 1 m s-1, 1.5 m s-1 and 2 m s-1, under laboratory conditions. Results indicated that the effect of air temperature on the drying time of nopal slices was higher than the air velocity (p≤0.05). The drying time for nopal in thin slices was remarkably lower (99 %) compared to that for whole cladode (p≤0.05 and 50 % lower... |

| Abstract In this study, kinetics of eggplant drying was modeled in the laboratory-scaled Food Drying Oven (FDO) with resistance heater was designed and manufactured. The temperature, energy consumption and drying time of FDO were recorded by keeping the temperature of at different temperatures as 40, 50 and 60 °C. These saved values were chosen as the input parameters of the model. The weight value of the eggplant was taken as the output parameter. Linear and quadratic equations were developed for modeling and constant coefficients of these equations were estimated with Artificial Bee Colony (ABC), Gravitational Search Algorithm (GSA), symbiotic organisms search (SOS) algorithms. In addition, the performances of these models were compared with the model... |
