WebJan 7, 2024 · One can argue that both the Henderson–Pabis and the two-term models have similar structures and that it may not be surprising that both can have insignificant parameters. Hence, as a third equation, we proposed to use the Midilli model [ 36 ], which also has four parameters ( a, k, n and b ): (8) WebJan 20, 2009 · The Henderson and Pabis, the Lewis, the Page, and the logarithmic models obtained a coefficient of determination ( R2) greater than the acceptable R2 value of 0.93 at all drying temperatures ( Madamba et al. 1996 ). Generally, R2 and χ2 values varied between 0.9917–0.9982 and 0.000178–0.000783, respectively.
