发酵罐设计温度对发酵工艺的影响及其控制

作者:不锈钢储罐 时间:2018-03-23 09:55
不锈钢微生物发酵罐在发酵罐过程中所用的菌体觉大多数是中温菌,如霉菌、放线菌和一般细菌。它们发酵的多适生长温度一般在20~40℃。在发酵过程中,不锈钢发酵罐需要维持适当的温度,才能使菌体生长和代谢产物的合成顺利进行。 信息摘要:

3.4工业生产上的温度控制

工业生产上,所用的大发酵罐在发酵过程中般不需要加热,因发酵中释放了大量的发酵热,需要冷却的情况较多。利用自动控制或手动调整的阀门,将冷却水通入发酵罐的夹层或蛇行管中,通过热交换来降温,保持恒温发酵。如果气温较高,不锈钢储罐,冷却水的温度又高,就可采用冷冻盐水进行循环式降温,以迅速降到适温度。因此大工厂需要建立冷冻站,提高冷却能力,以保证在正常温度下进行发酵。
