A Comparative Analysis of Moist Heat Sterilization and Dry Heat Sterilization of Sterilizer

Of all the various ways of sterilization,heat sterilization is a method which early and widely used.Heat Power method include moist heat sterilization and dry heat sterilization.
The sterilizing effect of moist heat is better than dry heat under the same temperature,specific reason expression is:
1. The protein coagulation is related to the temperature and its water content, that is to say,the higher the water content,the lower the temperature for protein coagulation.The protein of the bacteria absorb water from steam sterilization,so comparing to the dry sterilization,the protein is easier to be curdled.

2.In the process of steam sterilization,steam release a large amount of heat which speed up the increase of humidity.Through above analysis,the sterilization temperature required for moist heat sterilization is lower than it required to dry heat sterilization,for example,at the same temperature,the sterilization time required for moist heat sterilization is less than it required to dry heat sterilization.
3.The penetrating power of moist heat sterilization is bigger than it is of dry heat sterilization,making the sterilization temperature penetrate to the whole product.
As a result,the effect of moist heat sterilization better than the effect of dry heat sterilization.
