Hold up in rotary driers

Update date: Aug 23

May 10, 2007 A steady state semi-empirical model was modified to predict solid hold-up and flowrate in rotary dryers. This model was incorporated into a heat and mass transfer model ;o predict solid moisture and temperature for inferential and model-based control purposes. Results of several experiments that have been used to investigate dynamics of the

    The solid particle movement in a rotary drum plays an important role in drying processes. The solid distribution in the drum affects the amount of contact surface between the solid and the gas. The retention time of solids influences the time particles can stay in contact with the gas in order to transfer heat and mass. Any heat and mass transfer model for a solid particle dryer must be able

    Rotary drum sugar drying is the last important unit operation used in the manufacture of raw sugar. In order to improve their design, operation and control, it is helpful to model their dynamic behaviour. One important aspect involves predicting the rate at which solids are conveyed through the dryer, so that hold-up of crystalline material can be better predicted
