Hydrogenated sterilizerSterilization process:

1, Pipeline connection: Make sure the circulation system is sealed, and the connection is reliable.

2, pretreatment: After the freezer 'online cleaning' (CLEANINPLACE, referred to as CIP) is not avoidedVaporized hydrogen peroxideThe surface of the pipe and the casing need to be temperature and humidity control on the surface of the lyophilizer, the gas flow pipe of the sterilization system (temperature 15 ° C ~ 30 ° C, relative humidity is within ≤30% RH). And check if the sterilization system is ready.

3. Sterilization: 35% or 50% of the hydrogen peroxide is vaporized into high concentrations of vaporized hydrogen peroxide and injects the region to be sterilized. And maintain a sufficient effect of vaporization of hydrogen peroxide (depending on the size) and concentration (≥700 ppm) to ensure that the microorganism is completely inactivated.

4, ventilation: Import a sterile air for air replacement, and quickly decompose vaporized hydrogen peroxide into water and oxygen by catalytic decomposition unit, and ultimately cause a vaporized hydrogen peroxide concentration in the lyophilized chassis to 1 ppm.

Hydrogenated sterilizerSterilization conditions:

The conditions of hydrogen peroxide sterilization are hard drying surfaces of the sterilized article. Secondly, items in sterilization are important factors to ensure sterilization effect. When sterilizing, the surface of sterilized items should be maximized, no sterilization angle.

The humidity in the sterilization time is less than 30% RH, and the hydrogen peroxide has a dehumidifier (too large, dehumidification time) or the vacuum dehumidification function of the user freezer, and the temperature difference inside and outside the cabin should not be too large. When sterilizing, the temperature of the freeze dried machine is 30 ° C.
