Mathematical modelling of paddy drying in hybrid greenhouse dryer
Author(s): M Madhava
Abstract: During paddy growing seasons, paddy drying experiments were performed on three separate bed thicknesses (5, 10 and 15 cm) in hybrid greenhouse dryer. Paddy-drying continued until a moisture content of 12 percent (d.b) was achieved, moisture content converted to a moisture ratio (MR). Moisture ratio MR of paddy during drying was fitted to the eleven thin layer drying models. The most fitting models was the logarithmic model to explain the drying characteristics of paddy dried during Rabi season in thin layer. Logarithmic model gave R2 = 0.9891, χ2 = 0.00689, RMSE = 0.024477 and MBE = 4.02×10-8. Midilli model was the best one that can describe the drying behavior of the Kharif Paddy thin-layer drying. Midilli model gave R2 = 0.9953, χ2 = 0.0000408, RMSE = 0.019042 and MBE = -1.3×10-5.
