Analysis of the Influence of Orpheum Dry Fog Space Sterilization on the Ambient Humidity of Workshop

Orpheum dry fog space sterilization through the atomization of Nofos sporicide into gas diffuses into the workshop space to kill the air or surface microbes, thus reaching the new GMP requirements for the production of clean area microbial quantity standards. So does the atomized sporicide have an effect on the humidity of the workshop environment? Many industry people or experts have such concerns. Because humidity is one of the environmental control factors in the workshop, the humidity of some workshops must be within a reasonable range to ensure that the working environment of the personnel is comfortable or the quality of the product is not affected by moisture. Reasonable humidity can also reduce bacterial growth and humidity on the other hand. High impact. In this regard, we have carried out a theoretical analysis and actual space disinfection inspection of Orpheum dry mist sterilization, the purpose is to comprehensively analyze the impact of the dry mist sterilization system on the ambient humidity of the workshop.

Humidity, a physical quantity indicating the degree of dryness of the atmosphere. The less water vapor is contained in a certain volume of air at a certain temperature, the more dry the air; the more water vapor, the more humid the air. Humidity H = mass of moisture in wet air / quality of dry air in wet air. In this sense, physical quantities such as absolute humidity, relative humidity, and dew point are often used. If the temperature of the saturated air drops below the dew point and there is condensation in the air (there is always a condensation meter in nature), the water in the air will condense. Air humidity refers to the degree of moisture in the air and can be expressed in terms of relative humidity (RH). Relative humidity refers to the percentage of the actual vapor density of air and the saturated water vapor density at the same temperature. The best relative humidity for the human body to feel comfortable indoors is 40% to 50%.

Orpheum dry fog sterilization equipment uses 4mL / cubic meter of sporicide dosage, one kilogram of sporicide can atomize 250 cubic meters of space, enough to achieve sterilization effect, causing 6 logarithms for thermophilic fat spores reduce. How much impact does a kilogram of sporicide spread evenly into a 250 cubic meter space on the humidity of the air environment? In other words, what is the maximum increase in the humidity of the workshop environment? According to scientific data, the next cubic meter of air can accommodate up to 30 grams of water vapor at 25 ° C (no condensation occurs at this time). According to this calculation, 250 cubic meters of air can hold 7500 grams of water vapor. In other words, when the space of 250 cubic meters reaches saturated steam, the relative humidity is 100%, and the mass of moisture containing water is 7.5 kg. Then the amount of sporicide is 1kg divided by 7.5kg equal to 13%, and the humidity of the environment is increased by 13% by the maximum humidity of the Ufim dry mist after sterilization. If the humidity in the workshop environment is 40%, the maximum humidity in the workshop environment after atomization reaches 53%, far less than 100%, and there is no condensation. Exhaust after fresh bacteria and fresh air injection will quickly reduce the humidity, after a few hours of operation it is estimated that the humidity will return to the original value.

In order to better explain the impact of the Orpheum dry mist sterilization system on humidity, a field test was conducted specifically, taking Qingfeng Pharmaceutical as an example. The workshop environment has an original humidity of 45% and a temperature of 25 °C. According to the space usage of 4ml/m3, the on-line monitoring humidity of the Ufim dry fog is 55%, the relative humidity actually increases by 10%, and then 2 hours. After the air conditioning system is running, the humidity returns to the original 45%.

Therefore, it is concluded that the Orpheum dry mist sterilization system does not affect the humidity of the workshop environment before and after sterilization, and there is no condensation phenomenon, but the process will have a little humidity change, and this change It is also within the controllable range and does not cause any adverse effects on the shop or product.

[Overview of Dry Mist Sterilization System]

The Orpheum Hydrogen Peroxide Dry Mist Sterilization System is imported from Europe and France. It is designed for the new GMP. The dry mist sterilization system and space sporicide can meet the requirements of disinfection and sterilization in clean areas, and it is easy to pass GMP verification. The sporicide is high-purity hydrogen peroxide, which is one hundred times more active than hydrogen peroxide. It completely kills microorganisms, produces no drug resistance, and is non-toxic and non-irritating. It is a perfect substitute for formaldehyde fumigation. Good value for money, the tens of thousands of yuan can achieve such an effect is most suitable for domestic pharmaceutical companies to use, saving production and improving efficiency.

【Dry fog sterilization system application】

It can be used for disinfection in clean area, A/B area sterilization in pharmaceutical production area, C/D area disinfection, sterile room air disinfection, microbiology laboratory space sterilization, food processing production workshop disinfection, production workshop space sterilization, Biosafety laboratory space sterilization and other places that require space for sterilization and sterilization, as well as small space sterilization such as freeze dryer, sterile transfer window, sterile isolator, safety cabinet.
