柑桔汁超滤传质过程机理的研究

The Mechanism of Mass Transfer in Ultrafiltration of Orange Juice

摘要:

以“凝胶层阻力”及“渗透压阻力”理论为基础，根据柑桔汁在超滤过程中的通量变化规律，求出柑桔汁超滤过程的传质方程式，同时研究了操作压力对膜通量的影响，分析了造成传质阻力的主要因素，探讨了柑桔汁超滤过程的传质机理。

Abstract:

According to the regularity of membrane flux changes in ultrafiltration of orange juice, a mass transfer equation was developed to reveal the mechanism of mass transfer in ultrafiltration of orange juice. Moreover, the effect of operating pressure on the membrane flux and the key factors influencing the resistance to mass transfer in the ultrafiltration were analyzed.
