The volumetric shrinkage index determines the relationship between the seed volume, moisture content, and initial volume.
The volumetric shrinkage index of Jatropha seeds during the drying was determined by the relationship between the seed volume to each moisture content and the initial volume, as shown below:
psi] : volumetric shrinkage index, decimal; V: volume for each moisture content, [mm.
The experimental data of the unitary volumetric shrinkage index were fitted to the models described by the expressions listed in Table 1.
2]) for models fitted to the volumetric shrinkage index in Jatropha seeds subjected to drying under different temperature conditions are presented in Table 2.
The exponential and linear models showed a biased distribution under all of the conditions studied, and the polynomial model showed more drying conditions with random distribution, the desired behavior for the description of the volumetric shrinkage index in agricultural products.
