Abstrakt

A deep bed drying model for the description of moisture and temperature on an individual pellet level has been developed. Experimental validation is carried out in a special designed lab batch dryer, based on recordings of average moisture content and pellet surface temperature, on the air exhaust side. The model comprise empirical recording of moisture desorption isotherms and semi-empirical relations for moisture diffusivity and heat and mass transfer coefficients, in particular including the effect of air temperature on moisture diffusivity.
