First understand the concept of “dry fog”
Dry fog—refers to liquid particles less than 10 microns in diameter.
- Dry fog has the following properties: (The smaller the dry fog particles, the more obvious the following characteristics)
- The dry droplets move randomly (the principle of Brownian motion) and will not settle;
- Dry droplets will not aggregate together to produce large droplets;
- The dry mist droplets will rebound after contacting the surface without breaking and making the surface wet;
Therefore, these properties of dry fog make it very good in diffusivity, leaving no dead corners during disinfection; not moisturizing the surface; not corroding equipment and color steel plates.
Second, the principle of dry fog hydrogen peroxide disinfection machine:
The 2010 edition of “Pharmaceutical GMP Guidelines” for sterile drugs, pages 418~419, has a detailed introduction to the sterilization principle, and there is no formaldehyde fumigation content.
Sterilization is accomplished by spraying a dry mist on the area to be sterilized. When the average diameter of the droplets is less than 10 microns, the sprayed mist is called “dry”, so it is called “dry mist”.
three. The composition of the automatic hydrogen peroxide dry mist sterilizer (Terne as an example):
High-efficiency sporicide (hydrogen peroxide + peracetic acid) + our fog sterilization equipment
Fourth, the advantages of automatic hydrogen peroxide dry fog disinfection machine:
The fully automatic hydrogen peroxide dry mist sterilizer system uses compressed air as the carrier gas to quantitatively supply the disinfectant. When a small amount of liquid enters the nozzle through the siphon principle and encounters the high-speed carrier gas, the gas will strongly collide and smash the droplets. Quickly deliver dry mist particles below 10 microns to the distal end and spread to the entire space to achieve efficient sterilization.
The fully automatic hydrogen peroxide dry fog disinfection machine uses low-concentration hydrogen peroxide and peracetic acid sporicide to achieve log6 level disinfection and sterilization; it is used in indoor environments to quickly kill viruses and fungi in the air and surfaces of closed spaces , microorganisms such as mold and spores. Using low-concentration hydrogen peroxide, only a few milliliters are needed per cubic meter, the ambient humidity rises a little, and there is no corrosion to instruments, computers, and metal products in the environment. In the process of disinfection and sterilization, there is no need for heating, neutralization and other processes, which is convenient and fast.
