在抗生素发酵过程中,需不断通入大量无菌空气,以利分泌抗生素。因此,可靠的空气预处理和除菌设备对保证发酵正常十分重要。目前,沿海潮湿地区空气预处理大都采用“二冷析水再加热”的工艺流程,即压缩空气经两级冷却器冷却至露点以下析出水分,再经加热器升温,使压缩空气的相对湿度降至60%以下。进入棉花—活性炭过滤器除菌。当采用“二冷析水再加热”工艺流程时,很多生产单位片面认为空气冷却降温的程度愈
During the fermentation of antibiotics, a large amount of sterile air must be continuously fed to facilitate the secretion of antibiotics. Therefore, reliable air pretreatment and sterilization equipment is very important to ensure the normal fermentation. At present, air pretreatment in wet coastal areas mostly adopts the “second cold water reheating” process, that is, the compressed air is cooled to the dew point below the dew point of the compressed air, and the temperature is increased by the heater to reduce the relative humidity of the compressed air. To 60% or less. Into the cotton - activated carbon filter sterilization. When adopting the “second cold water reheating” process, many production units think that the degree of air cooling will decrease.
