好氧微生物发酵罐对空气分布器设计的需求

作者:发酵罐 时间:2018-01-26 14:11
空气分布器在搅拌器下方的罐底中间位置,管口向下,空气直接通入发酵罐的底部。管口与罐底距离约为40㎜,管径可按空气流速20m/s左右计算。新型的喷环式空气分布器已成功用于柠檬酸发酵生产。 信息摘要:

好氧菌繁殖需要氧气,充足的氧气分布能够促使菌体旺盛的生长,微生物发酵水果拉霸多人版罐中空气分布装置及空气的制备装置都影响氧气的工艺与氧气的质量。好氧微生物发酵罐中的空气分布器是将无菌空气导入罐内的装置。空气分布管的形式对溶氧速率有较大的影响,采用的空气分布装置有单管、多孔环管及多孔分支环管等几种。

新型的喷环式空气分布器已成功用于柠檬酸发酵生产。它是将传统的鼓泡传质转化为乳化传质,使气泡上升速度降低,不锈钢白酒储罐,在不改变原有搅拌系统的前提下,可降低搅拌功率10%以上。其主要是利用文丘里管的引射产生真空的原理;具有定压力的无菌空气,经喷咀在混合器中与气体剧烈混合并达到乳化的效果。从而增大了气体与液体的接触面积,减缓了气体在液体中逸出时间,提高了溶氧效率。
