What kind of disinfection methods are generally used in the inner packaging workshop?

In the food industry, the cleaning and disinfection of the processing workshop is a comprehensive systematic project, which can not be guaranteed by a single project. Therefore, it is of great significance to understand and reasonably use the relevant cleaning disinfection products. Appropriate sterilization scheme will reduce the risk of microbial contamination. At present, the most commonly used workshop cleaning disinfection products in food enterprises are: 75-degree alcohol, ozone, ultraviolet lamp, etc.

Alcohol: the concentration of 75% must be ensured during disinfection, and the sterilization effect cannot be achieved if the concentration is too high or too low.

Advantages: colorless, odorless and quick to volatilize.

Disadvantages: In addition, the sterilization effect of alcohol is general, and it can only kill some kinds of bacteria and viruses, but it is ineffective for fungi. Mold is a kind of fungus with strong resistance. If alcohol is chosen to kill mold, disinfection will inevitably fail. The permeability of alcohol to concave and convex surfaces is not strong; The killing rate of virus and spore is low; Flammable and explosive, not convenient for large-area workshop spraying; High cost, unsafe.

Ozone:

Advantages: strong oxidant can kill many microorganisms;

Timing, simple operation and ideal effect on space environment; It is more suitable for space disinfection, and the surface disinfection is prone to blind spots.

Disadvantages:

Due to the superposition of fungi, mold and mold spores, the problem of fungal pollution cannot be completely solved; Ozone is highly toxic and needs to be strictly controlled, but it is difficult to control the ozone concentration under actual use conditions. When the concentration of ozone in the environment is high, it will cause damage to human cells and have carcinogenic and mutagenic effects. A small amount will cause dizziness, headache, chest tightness and other injuries, and avoid the toxic effects caused by excessive ozone concentration.

Ozone can kill irregular packaging and can only be used in batches, so it is difficult to deal with it in batches. It is corrosive to metal, rubber, silk, etc., and should not be used for a long time.

Ultraviolet lamp:

Common form: ultraviolet germicidal lamps are evenly distributed on the ceiling of the workshop, and the surface of the object and the air are disinfected by the ultraviolet rays generated by them.

Advantages:

Simple operation, low price, convenient and flexible management, and can disinfect a single room at any time according to production needs without adding or generating any toxic and harmful substances; .

Disadvantages:

The intensity of ultraviolet light emitted by ultraviolet lamp decreases with the increase of use time, so the disinfection and sterilization ability is weakened continuously. Ultraviolet rays have weak penetration and are easily blocked by production equipment, resulting in dead corners and affecting sterilization effect. Ultraviolet sterilization is greatly influenced by relative humidity, and its sterilization effect is obviously reduced when the relative humidity of clean room is >: 60%. Relative humidity >; 80%, it should not be used. Ultraviolet radiation has low energy and can only kill directly exposed microorganisms. Therefore, the disinfection site must be fully exposed to ultraviolet light. Don't use it when someone is working.

A new type of ecological disinfectant-food-grade silver hydrogen peroxide compound disinfectant-is represented by Novo Belgium high-efficiency disinfection and sterilization agent.

Principle of action: Hydrogen peroxide produces hydroxyl active free radicals under the action of silver ions, which attacks microbial cell walls and destroys cell structure and function; The combination of silver ions and bacterial proteins prevents the replication and metabolism of pathogens; The combination of silver ions and cellular enzymes inactivates cells.

Advantages:

Efficient sterilization; The sterilization rate is more than 99.999%, which can kill spores, fungal spores and other highly resistant microorganisms. Broad spectrum effect; It can kill more than 200 kinds of harmful microorganisms, including mold, Escherichia coli, salmonella and so on. , non-toxic, no residue. Environmental protection, decomposed into water and oxygen after action, harmless to products, human body and environment. Good stability; Not affected by temperature, light and other factors, the storage period can be as long as 5 years.

Widely used for disinfection of packaging materials, but also for disinfection of environmental air, objects, water and other links. It is clean and contains no other impurities.

Disadvantages:

Compared with chlorine-containing disinfectants, the use cost is higher; Single supplier. At present, the technology of silver-hydrogen peroxide composite disinfectant is only mastered by a few countries and needs to be imported.

Novo food-grade disinfectant, as a new type of environmental protection workshop disinfectant, has been widely used in microbial control in various industries in Europe. After ten years in China, I have served thousands of enterprises. Novartis food-grade disinfectant plays an absolute role in microbial control in production workshop. More importantly, Novo Horizonte can tailor the sterilization service plan according to the characteristics of the enterprise.
