BILLIRIS, ALEJANDRA, Autor ; T. THUROW, Autor ; SIEBENMORGEN, TERRY J., Autor | 2016Individual kernel drying rates could be used to better estimate intra-kernel MC and material state gradients, which in turn would help estimate the occurrence of kernel fissuring inside rice dryers. Drying curves of individual kernels were obtai[...]texto impreso
