The high pressure steam sterilizer has two types: a lower pressure steam sterilizer and a pre-vacuum pressure steam sterilizer. The lower row pressure steam sterilizer includes both portable and horizontal.
(1) The lower exhaust pressure steam sterilizer has a vent hole at the lower portion, and utilizes the difference in specific gravity of the hot and cold air during sterilization, and the cold air is forced to be discharged from the bottom vent hole by the vapor pressure at the upper portion of the container. The temperature, pressure and time required for sterilization vary depending on the type of sterilizer, the nature of the item, and the size of the package. When the pressure is between 102.97 and 137.30 kPa, the temperature can reach 121 to 126 ° C, and the sterilization purpose can be achieved within 15 to 30 minutes.
(2) Pre-vacuum pressure steam sterilizer, equipped with a vacuum pump, vacuums the inside before introducing steam to form a negative pressure to facilitate steam penetration. At a pressure of 205.8 kPa, the temperature reaches 132 to 134 ° C and can be sterilized in 4 minutes.
