HEAT AND MOISTURE SIMULATION OF A DRYING PROCESS WITH A TWO FLUID MODEL IN A FLUIDIZED BED

One of the most effective processes in drying is the use of a fluidized bed with a hot air stream. In this article, a two- fluid model is used in order to predict the drying rate of products. Hence, the temperature and humidity of grain and gas can be determined. The effect of parameters such as inlet gas temperature and grain diameter is investigated. Experimental data is compared with the model prediction and are shown to be in a close agreement.
