| Abstract: | The moving and water evaporation of honey-mixed liquor in centrifugal spray drying tower were studied.By combining matter properties of honey with characteristics of spray drying,the atomization model of centrifugal atomizer and CFD models including moving model of 2 phases of gas and solid and evaporation model in spray drying chamber were established with Fluent software.The spray drying process of honey was emulated and the temperature distribution of air flow,moving path and evaporation condition of fog droplet in spray drying chamber were observed.And the adaptivity of this model was validated through experiments and the optimum technological condition for spray drying of honey was obtained. |
