KINETICS OF FENUGREEK DRYING IN AN INDIRECT SOLAR DRYER
要約
In this paper, kinetics of fenugreek drying on different trays of an indirect solar dryer was examined so as to increase its shelf life. For this purpose, a thin layer of 2 kg of fenugreek was placed on three different trays of dimensions 0.7 m × 0.7 m, to be further dried until there is no variation in its mass. The drying rate is fitted in different models available in the literature and the best model is obtained by comparing the values of the diffusion coefficient, root means square error, and the sum of square due to error. The diffusion coefficient of fenugreek on different trays was also investigated and found in the range of 2.422 × 10-8 m2/s to 3.872 × 10-8 m2/s. An average efficiency of the dryer in peak hours on the first and second days of drying was 38.63% and 7.56%, respectively.
