Mathematical Model and Experimental Analysis of a Solar Dryer with Parvati Geometry for Coffee Beans
This article reports a mathematical model with experimental measurements of a novel solar dryer named: Parvati Solar Dryer (PSD), which consists of a double angle linear collector and a cylindrical drying chamber with a translucent surface. Semi-theoretical and empirical thin-film models were evaluated to select the one with the best fit (higher coefficient of determination R2 and lower mean square error RMSE) in terms of the humidity ratio MR and taking into account that the drying chamber temperature does not exceed 35 ℃ to maintain the quality of the coffee.
