SOME ASPECTS OF MODELING CONVECTIVE CORN DRYING

Specific heat claim of dewatering at large scale convective com driers could be reduced to about 3000 kJ/kg by means of an accurate modelling of the drying process. The main inadequecy of the models used in these days is the ignorance of change caused by interactions between some process parameters and material features during drying process. In this study dehydration of seven Pioneer type hybrids was tested at model and large scale driers. By an empirical resolution of specific heat and bulk density functions of shelled com furthermore by establishing a drying speed equation depending on the main grain- and process-features an appropriate result was provided.
