摘要 发酵罐是化工生产中的主要化学反应装置。它的功能是：物料均匀混合；液相气体良好分散；液相颗粒均匀悬浮；另一相的均匀悬浮液或总乳状液谷氨酰胺单钠添加剂、发酵系统、食品工业等新实用产品的主要成分。包括：立方体、搅拌机、传热装置、轴封等，必要时可增加其它附件，如门的安装、焊接；手动开孔及各种连接线（用于内部零件的修理、装卸、温度计、压力表等），保护减压装置为物料的化学反应提供一定的空间，搅拌器由驱动装置、搅拌轴和搅拌器组成。它的功能is:至不同反应物料的混合，混合装置可分为两类：不潜水）只有变速箱和减速机，I传动系统，传热装置位于筒体或锅炉的外壳外，是控制反应所需材料的温度。 组织者设计为63厘米六面，相当于一个大体积的设计。它使用热管和三步混合。 关键词:搅拌罐搅拌器传热装置轴封装置 ABSTRACT Ferme
