Pharmaceutical workshop sterilization
Sterilization in the pharmaceutical workshop
Dry Fog Hydrogen Peroxide Sterilization Technology
Safe, efficient, and eco-friendly pharmaceutical workshop environment disinfection solution, comprehensively replacing traditional formaldehyde fumigation
Technology Overview
In pharmaceutical workshop environment disinfection, many enterprises use formaldehyde fumigation disinfection and sterilization methods, which are low-cost and have excellent sterilization capabilities. However, the high toxicity of formaldehyde, strong hazards, inconvenient operation, and damage to employee health are being recognized and eliminated by more and more enterprises. Formaldehyde is prohibited in European pharmaceutical companies. [5,6](@ref)
Teling Biotechnology integrates the actual application needs of pharmaceutical enterprise sterilization experts and new technology solutions for pharmaceutical workshop environment disinfection. This introduces the advantages of dry fog hydrogen peroxide sterilizers for pharmaceutical workshop environment disinfection and explains the principle, composition, use, and validation of the Teling Biological Space Dry Fog Sterilization System.

Dry fog hydrogen peroxide sterilization technology has been applied to European pharmaceutical workshop environment disinfection for nearly 20 years. Especially in recent years, under the EU's limited formaldehyde usage environment, dry fog hydrogen peroxide sterilization technology has developed rapidly. Although it cannot be quickly popularized for all categories, the abandonment of formaldehyde sterilization in the EU shows that the entire industry, whether managers or participants, is striving to find a product that can replace formaldehyde for sterilization.

What is Dry Fog
Dry fog refers to extremely fine liquid droplets with a diameter of less than 10 microns, possessing unique physical characteristics that make them ideal sterilization carriers. [5,6](@ref)
Dry Fog Size
Dry fog refers to extremely fine particles with diameter less than 10μm [5,6](@ref)
Irregular Motion
Dry fog particles move irregularly (Brownian motion principle) [5,6](@ref)
Non-condensing
Dry droplets do not easily coalesce to form large droplets [5,6](@ref)
Non-adherent
Dry fog particles rebound upon contact with surfaces, not easily adhering [5,6](@ref)
Teling Biotechnology's dry fog sterilization technology solution is the product of collaboration between aerodynamics experts and sterilization technology experts. It was developed using high-tech science and technology, experimental simulation, technical verification, practical application, and pharmaceutical factory monitoring. Its main feature is to make air move at high speed under high pressure, collide with bactericide, and produce dry fog particles with a diameter of less than 10 microns. To achieve complete sterilization effect, kill harmful bacteria, and control harmful microorganisms, it can replace the technical solution of formaldehyde fumigation. [1,2](@ref)

Pharmaceutical Industry Applications
In the pharmaceutical industry, dry fog hydrogen peroxide sterilization technology is widely used in sterile production workshops, API synthesis areas, preparation filling rooms, and other critical production environments. The system can effectively kill spores and other stubborn microorganisms, ensuring that the pharmaceutical production environment meets GMP requirements. [1,6](@ref)
Teling Biological dry fog sterilization system supports the entire process from R&D to commercial production, providing professional sterile assurance for pharmaceutical enterprises. [1,2](@ref)
Laboratory Applications
In biotechnology laboratories and research institutions, dry fog hydrogen peroxide sterilization technology provides a sterile operating environment for sensitive experiments. The system can be safely used in various experimental scenarios such as PCR laboratories, cell culture rooms, and microbial testing rooms. [3,6](@ref)
Dry fog technology ensures the sterile state of the experimental environment, prevents cross-contamination, and guarantees the accuracy and professionalism of experimental data. [3,9](@ref)
Medical Facilities Applications
In hospitals, clinics and other medical facilities, dry fog hydrogen peroxide sterilization technology can be used for disinfection and sterilization of key areas such as operating rooms, ICU wards, and drug preparation rooms. [4,10](@ref)
The system's rapid and efficient sterilization capability can significantly shorten the disinfection cycle, improve the efficiency of medical facilities, while ensuring the safety of patients and medical staff. [4,10](@ref)
Operation Process
The standard operating procedure for the dry fog hydrogen peroxide sterilization system is as follows: [6](@ref)
Equipment Placement
Nozzle away from walls and equipment to ensure even diffusion of dry fog
Equipment Preparation
Secure equipment, install appropriate amount of disinfectant, connect power
Environment Preparation
Turn off air conditioning, exhaust fresh air, close doors and windows
Start Sterilization
Click the start button, the equipment automatically performs dry fog sterilization
Completion Treatment
After spraying is completed, let it stand for 90 minutes, exhaust for 1 hour
From the start of disinfection to safe personnel entry, the entire disinfection process takes about 4-6 hours (including ventilation). Compared with traditional formaldehyde fumigation which requires more than 48 hours of exhaust time, dry fog hydrogen peroxide sterilization technology significantly shortens the production downtime and improves production efficiency.

Verification and Certification
Sterilization effect verification of hydrogen peroxide dry fog sterilization system: [6](@ref)
The sterilization effect of the hydrogen peroxide atomization sterilization system can be verified. According to the Chinese Pharmacopoeia, using Bacillus subtilis as the challenge test bacterium, a kill rate of 10³-10⁶ can be achieved, that is, a reduction of 3-6 logarithmic units, which can prove the system's ability to kill various microorganisms during the space sterilization and purification process.
