Mathmatical Model of Drying Process in Downwards Cocurrent Pressure Spray Dryer and Dryer Design Software

Chen Yuanyuan,Wang Guoheng  
According to the fog drop forming theory and its force analysis of pr essure atomizing dryer ,the paper makes a mathematical describe on the drying p rocess applying the knowledge of hydrodynsmics and heat and mass transfer.Thus ,it provide a foundation of calculating the drying time,drying air quantity,t he height and diameter of drying tower and design sizes of the sprayer.Based on this,a Visual Basic programme of downwards cocurrent spray drier.While differ ent parameters such as atomizing pressure,characters of drying gas are put in, we can corresponding receive different drying tower structure sizes,drying time and quantity of drying gas.There is a good agreement between calculated result s and real parameters of a milk-product dryer.So,it make the mathematical sim ulation experiment come true.On the optimization combination of energy and mate rial dealed with and energy saving,it also has made a try.
