(1) related proteins needed for the solidification temperature and its water content, the greater the water content, lower when the temperature of the solidification takes place. So easy to make it easier for bacteria protein denaturation, to achieve the effect of sterilization. Damp heat sterilization of bacteria protein absorb moisture, due to the larger the same temperature of the hot air is easy to set. (2) warm vapor released a large number of latent heat sterilization process, accelerate improve the humidity. So wet and heat sterilization than dry to low temperature, such as in the same temperature, the time needed for damp heat sterilization shorter than dry. (3) wet and heat penetration is bigger than dry, make deep also can achieve the sterilization temperature, so hot and humid than dry heat with the outcome.
