The fabric program of the pulsating vacuum sterilizing cabinet can not be manually cooled down and open the door, this is due to the fabric program of the pulsating vacuum sterilizing cabinet is carefully designed, including pre-treatment, main treatment and post-treatment and other stages, each stage of the temperature, pressure and time and other parameters have strict requirements to ensure that the sterilization effect and quality. The working principle of the pulsating vacuum sterilization cabinet is mainly through the vacuum pump with the help of water flow to pump out the cold air inside the sterilization cabinet, so that it is in a negative pressure state, the input of saturated hot steam, so that it quickly penetrate to the inside of the items, repeated 3 or 4 times, at high temperatures and under the action of high pressure to make microbial proteins denatured coagulation and inactivation to achieve the sterilization requirements.
