生啤酒膜法过滤除菌技术的试验研究

阐述了生啤酒膜法过滤除菌技术的试验研究方法。着重讨论了膜孔径的选择试验及操作压力，主流液流速对浓差极化和渗透通量的影响，运用二次回归正交组合设计的方法建立数学模型，寻求操作参数的最佳值，并初步探索了膜的再生方法。

THE EXPERIMENTAL STUDY OF STERILIZED DRAFT BEER WITH MEMBRAND FILTRATION

The main object of this paper is to study the effect of membrane filtration on making steril-ized draft beer. The experiments have proved that suitable pore size of membrane can makeexcellent draft beer within National Hygiene Standard. High operation pressure or low veloci-ty of feedstock can make serious concentration polarization, on the other hand,high opera-tion pressure or high velocity of feedstock can make high permeat-retentate. The quadraticregressive equation has been established,the most suitable data have been found for themembrane filtration of draft beer, it also provides the reliable basis for the further investiga-tion. Experiments are made to find the means of detergents periodic cleaning.
