Abstract

Two-dimensional Computational Fluid Dynamic(CFD) calculations for multistage zeolite drying are performed for two dryer configurations 1) a continuous moving bed zeolite dryer and 2) a discrete bed zeolite dryer. The calculations concern drying of tarragon (Artemisia dracunculus L.) as a herbal product. The results reveal the profiles of water, vapor and temperature in dryer, adsorber and regenerator in the flow directions. The thermal efficiency ranges between 80-90% and is close to overall model calculations. The performance of continuous moving bed zeolite dryer is the best. Residence time of air, product and zeolite are in accordance to other drying systems. Key words and phrases: Adsobent drying; regeneration; zeolite; terragon; thermal efficiency; model; Moving bed dryer
