Introduction of sterilization principle and process of pulsating vacuum sterilization

Published Date:05-01-2021    Source£º    Author£º  Viewed£º774

Pulse vacuum sterilization is a high-temperature steam sterilization method. Steam sterilization is an ancient sterilization method, which has been used for a long time. With the progress of sterilization technology, high temperature steam sterilization has evolved into a pulsating vacuum sterilizer with better sterilization effect. The sterilization of pulsating vacuum uses saturated steam as the sterilization medium and uses mechanical vacuumization to vacuum the air in the sterilization room and inject steam. When the set pressure and time are not reached, vacuumize and inject steam again. When the set temperature and pressure are reached, the biological movement is accelerated by thermal action, the biological protein peptide breaks, destroys the biological enzymes and structural proteins, and thus kills bacteria.

Pulsating vacuum sterilizer is a method of vacuumizing the sterilization chamber for many times and then rushing into high-temperature steam for many times. It is effective to replace the cold air in the sterilization chamber. When the set temperature, humidity and pressure are reached, the high-temperature steam is used for thermal sterilization. The structural proteins composed of bacteria accelerate the movement, and the ring breaking biological enzymes and structural proteins, This leads to microbial death. Moreover, under the action of vacuum pressure, the steam can diffuse to the outside and inside of the sterilized products faster, the sterilization is more thorough, and the damage to the sterilized articles is small.
