Sterilization principle and features

The TKSAGE-600 hydrogen peroxide sterilizer adopts unique low-temperature flash evaporation technology to vaporize  30%-35% hydrogen peroxide and quickly distribute it in the sterilization space to achieve space surface sterilization. The whole equipment is made of stainless steel, with smooth appearance and no dead ends, in line with GMP requirements. The user-friendly operation interface is simple and easy to operate, so users can quickly master the operating skills. The sterilization program adopts fully  automatic process control, which can monitor the process temperature, humidity, and hydrogen peroxide concentration in real time  and calculate the sterilization effect according to the real time parameters. The equipment can execute 6LOG sterilization program,  12LOG sterilization program, concentration/time program and other options to meet different needs of customers. The sterilization  process uses the dew point control method to ensure the vaporization state of the entire sterilization process.

VHP sterilization curve

The sterilization process is divided into four stages:

Start: Before sterilization starts, the equipment automatically determines whether the sterilization conditions meet the sterilization start requirements, i.e.:temperature>15°C, 40%< RH%<60%; Balance: The VHP generator starts to produce hydrogen peroxide vapor and circulates it through the space until it reaches a preset concentration or saturation level; Sterilize: The equipment starts to record the sterilization effect until the preset sterilization LOG value is reached. Degrade: At the end of the sterilization process, the equipment automatically enters the VHP degradation stage, which starts to catalyze the degradation of the hydrogen peroxide vapor inside the equip-ment and the cavity until it reaches the set hydrogen peroxide concentration.
