用于发酵工程的灭菌技术

Germ-killing technology for fermentation engineering

介绍了发酵工程中培养基灭菌及空气灭菌的基本方法和灭菌装置,结合蒸汽喷射连续灭菌装置及板式热交换器灭菌装置的特点,提出了将上述2种装置组合的培养基连续灭菌流程;通过采用玻璃纤维过滤器和金属过滤器对空气除菌,除菌率达99.999%。

The basic methods and equipment of the germ-killing technology of both culture and air in the fermentation engineering were introduced. Based on the characteristics of continuous germ-killing equipment by spraying vapor and panel heat exchanger, a continuous germ-killing flow process of culture was put forward, which combined the two above-mentioned devices. By using fiberglass filter and metal filter to kill the germs in air, the rate of germ killing reached by 99.999%.
