- Abstract
- Small bins were used to conduct cooling and drying experiments on wheat, barley and peas. Four conceptual models are described. They consider different ways in which water may leave the grain. A new equation has been developed to take the hysteresis phenomenon into account. The temperature front occurring at the beginning of the drying process is modelled. An optimisation procedure is used to adjust the parameters for the heat and mass transfer coefficients to this temperature front using experimental data. The best adjusted parameters are then used to compute the drying front. The four models give similar results and the general quality of the models with all three products are similar. Information extracted from the exchanges taking place in the temperature front are not sufficient to compute the drying front accurately. On the contrary, it is found that parameters obtained by optimising the models using results from drying experiments and the drying front give better predictions. (C) 1996 Silsoe Research Institute
