Simulation of fluidized bed drying of biosynthesis products

Abstract In the paper a procedure for the design of a fluidized bed dryer of biosynthesis products is presented. In this method a simplified mathematical model of heat and mass transfer in a fluidized bed dryer and deactivation kinetics of biosynthesis products during drying are utilized. The procedure is illustrated by the drying of yeast Saccharomyces cerevisiae. The effect of longitudinal dispersion on the process and results of fluidized bed drying in a continuous system are analysed.
