What is the sterilization of cold storage, and what is the special fungicide for cold storage?

, health management.

1. Cold storage environmental sanitation:

1.The area around the cold storage should be clean and hygienic.

2.The floor of the cold storage should be flat, and if there are cracks and potholes, they should be repaired in time.

3.Cold storage warehouses, corridors, etc. should be white, and the walls should be smooth and clean.

4.The cold storage floor and the incoming and outgoing corridors should be cleaned and washed with alkaline water regularly.

5.Warehouse disinfection: The total number of bacteria per 1cm2 of the surface of the structure in the cold storage warehouse (referring to the surface of the civil wall, column, floor, ceiling and various cold distribution equipment in the warehouse) should not exceed 100.

The general disinfection work is carried out after all the food in the warehouse is cleared, and it is often carried out continuously with the painting work in the warehouse.

1) Ultraviolet disinfection: use ultraviolet radiation sterilization and disinfection. Each square meter of warehouse space needs to be irradiated with 1w ultraviolet light for an average of 3 hours per day and night, this method is simple to operate, the cost is small, and the effect is good, but the sterilization of objects with rough surface is slow.

2) Antifungal disinfection: made of sodium fluoride or iron fluoride or ammonium fluoride added to white clay (white clay containing calcium salt or white clay without calcium salt). It is brushed and has strong bactericidal power. Alternatively, it can be applied with a stucco mixture containing 2% sodium peroxyphenol saline.

3) Disinfectant disinfection: sprinkle the warehouse with 2 4% sodium hypochlorite solution and 2% sodium carbonate mixture and close the door. It can also be disinfected with 2% sodium diphenyl ether aqueous solution to wash walls, columns, floors and ceilings.

The former method is applicable to the storage temperature below -4, and the latter should be above the storage temperature of -4. After the two methods are carried out, ventilation is obtained. If the storage temperature can rise to 5, it can also be used to dissolve the bleaching powder containing 25% chlorine and sodium carbonate in 100 parts of water to make a bleaching powder mixture.

4) Deodorization: In addition to the odor in the warehouse, the empty warehouse can be sprayed with 2% formaldehyde aqueous solution or 5 10% acetic acid and 5 20% bleaching powder aqueous solution. This method is easy to operate, but it needs to be cleared out of the warehouse.

8.The sewers in the cold storage should be cleaned regularly and disinfected with a 5% bleach solution.

9.When washing the frost, the goods near the frost should be covered and carried out, and it can also be carried out with a scraper, a hard broom, etc. Frost chips should be shipped out of stock.

10.Refrigerated food should be kept clean and free from contaminants.

It is mainly sterilized by mechanical removal methods, physical ultraviolet light sterilization methods, and sterilization methods using chemical reagents.

With an ozone generator.

Ozone is recognized worldwide as a broad-spectrum and highly effective disinfectant. Air or oxygen is used as raw materials and high-frequency and high-voltage discharges are used to produce ozone. Ozone has one more active oxygen atom than oxygen molecules, ozone, which is particularly chemically active and is a strong oxidizing agent that can quickly kill bacteria in the air at a certain concentration.

There is no toxic residue, no secondary pollution will be formed, and it is known as "the cleanest oxidant and disinfectant".

Summary. Hello, it is a pleasure to serve you.

Ozone gas has become a new excellent disinfectant and fungicide due to its strong oxidation effect, and has advantages in food processing workshops, cold storage disinfection, deodorization and purification and food processing equipment disinfection, food surface sterilization, mildew prevention and preservation, etc., so it has been widely used and promoted.

Special ozone generators for cold storage can be bought on the market;

You can buy ozone ......

If it is disinfection and sterilization at home, then go to **a lot, **most of them are about 500, such as the posture elimination fruit is industrial, you need to determine the output of the ozone machine according to your own disinfection requirements, the size of the space, and then find the manufacturer!

In order to ensure that things are not dried at high temperatures, so as not to destroy the nutritional value and composition of things.

Freeze drying technology is a technology that cools the material containing a large amount of water in advance, freezes it into a solid below the freezing point, and directly sublimates the ice under vacuum conditions, so as to remove the water to obtain a dried product. For drugs that are sensitive to heat and unstable in aqueous solution, dry powders can be prepared by lyophilization.

How to use the freeze dryer and precautions.

1. When we turn on the main power switch of the freeze-drying machine, pay attention to keep the air pressure digital display of Huai Kai at 110pk.

2. You want the temperature to be a cold trap.

The actual temperature, we can press and hold the freeze dryer control panel.

On the total on/off key for more than three seconds.

3. Start the refrigerator.

After that, we should pre-cool for more than 30 minutes before using.

4. Put the sample into the sample holder, cover it with a plexiglass cover, and start the vacuum pump.

5. Wait until the air pressure digital display is stable, record the temperature and air pressure values at any time.

Summary. Sodium fluoride method: Sodium fluoride (or iron fluoride) or ammonium fluoride is added to the white clay to prepare an aqueous solution to paint the wall. The amount of calcium salts in white clay should not exceed or preferably do not contain calcium salts.

Sodium hydroxybiphenol method: When the mildew is serious, in the warm warehouse, the wall can be brushed with a sodium hydroxybiphenol solution, or the same concentration of chemical solution is prepared into a whitening mixture for painting. After disinfection, the floor should be washed and dried and ventilated before the warehouse can be cooled and used.

This method should be used to disinfect and not alternate or mix with bleaching powder to avoid a maroon appearance on the wall.

What is used for disinfection of constant temperature cold storage.

Hello to provide you with the disinfection method of cold storage.

Hello to provide you with the disinfection method of cold storage.

It can be rinsed with hot water first, and degreased with 2% concentration of alkaline water (50), and then disinfected with a bleach solution containing available chlorine. All equipment used in processing, such as iron plates, hooks, workbenches, etc., should be rinsed with clean water before and after use, and disinfected with hot alkaline water if necessary. The walkways and stairs inside the cold storage should be cleaned frequently, especially when entering and exiting the cold storage, the remnants of the bridge such as minced meat on the Minxiang floor should be cleaned in time to avoid polluting the environment.

The warehouse is disinfecting and painting money, and all the food in the cold storage should be moved out, and the dirt on the floor, wall and roof should be clear, and the place where mold is found should be carefully cleared with a scraper or brush. In the low-temperature cold storage, it is necessary to let the knowers remove the frost on the top of the wall and the row pipe, and if necessary, the temperature of the storage should be raised to the normal temperature. The effectiveness of disinfection in the storage temperature is evaluated by the reduction of mold spores.

Therefore, the pure defeat should be measured and recorded before and after disinfection, and after disinfection, there should be no more than one mold spores per square centimeter of surface.

Sodium fluoride method: Sodium fluoride (or iron fluoride) or ammonium fluoride is added to the white clay to prepare an aqueous solution to paint the wall. The content of calcium salts in white clay should not exceed or preferably do not contain calcium cavity salts.

Sodium hydroxybiphenol method: When the mildew is serious, in the warehouse at the right temperature, the wall can be brushed with a sodium hydroxyphenol solution, or the same concentration of the chemical solution is prepared into a whitening mixture for painting. After disinfection, the floor should be washed and dried and ventilated before the warehouse can be cooled and used.

This method should be used to disinfect and not alternate or mix with bleaching powder to avoid a maroon appearance on the wall.

Copper sulfate method: Mix copper sulfate rock imitation and potassium alum for the year, take this mixture and add water to dissolve it in a good wooden barrel, and add lime when painting. Paint with sodium peroxyphenol saline mixed with lime water.

There are several ways to disinfect in disinfectant warehouses. Bleaching powder disinfection: Bleaching powder can be prepared into an aqueous solution containing available chlorine (adding bleach containing effective chlorine to the water), sprayed in the warehouse for disinfection, or mixed with lime to paint the wall.

To prepare, the bleaching powder is first mixed with a small amount of water to make a thick slurry, and then water is added to the necessary concentration.

The above is the general way of disinfection of constant temperature cold storage for your reference.

Freezing is just a kind of low-temperature preservation of food, because the low-temperature environment does help to inhibit bacteria during the preservation process, but it cannot play a complete sterilization role.

Sterilization refers to the use of strong physical and chemical factors to make all microorganisms inside and outside any object permanently lose their ability to grow and reproduce. The commonly used methods of sterilization include chemical reagent sterilization, radiation sterilization, dry heat sterilization, moist heat sterilization and filter sterilization. According to different needs, different methods can be used, such as medium sterilization, which is generally sterilized by moist heat, and air is sterilized by filtration.

The thoroughness of sterilization is limited by the sterilization time and the strength of the sterilant. The resistance of microorganisms to sterilants depends on the density of the population originally presented, the resistance given to the culture by the culture, or the environment. Sterilization is a necessary condition for obtaining pure culture and is an essential technology in the food industry and in the pharmaceutical field.

Sterilization refers to the use of physical or chemical methods to kill all microorganisms, including pathogenic and non-pathogenic microorganisms and spores, to achieve a sterility guarantee level. After sterilization, the items that are not contaminated are called sterile articles. The area that is not contaminated after the sterilization process is called the sterile area.

Measures for the Administration of Hospital Infection (Order No. 48 of the Ministry of Health) (2006) Chapter VII Supplementary Provisions Article 3 Article 16 The meaning of the following terms in these Measures: (5) Sterilization: killing or eliminating all microorganisms on the transmission vector, including pathogenic microorganisms and non-pathogenic microorganisms, as well as bacterial spores and fungal spores.

At the same time, sterilization can be regarded as a process, so in the "GBT19974-2005 Sterilization of Health Care Products Characteristics of Sterilization Factors and General Requirements for the Setting, Confirmation and Routine Control of Medical Device Sterilization Process" has the following definitions: Sterilization The process used to make the early products of eggplant products warp without viable microorganismsThe resistance of microorganisms to sterilants depends on the resistance of the original population density, bacteria or environment to the bacteria. Sterilization is a necessary condition for obtaining pure culture and is an essential technology in the food industry and in the pharmaceutical field.

A sterile process is achieved by killing or removing the vegetative cells and their spores (or spores) of all microorganisms in the culture medium, fermentation equipment, or other targets.

Summary. Dear, hello Extended information: Cold storage is used to store food or yao products and other things that need to be stored at low temperatures for a long time.

To put it simply, anti-corrosion is the use of anti-corrosion to do surface elimination treatment for some lifeless organisms such as a certain space environment, items or machinery, which has the effect of eliminating or inhibiting the growth and reproduction of microorganisms. <>

Do <> cold storage need to be used for antiseptic disinfection for the first time?

Hello dear, I am happy to answer your <>

The first use <>of cold storage in the state is to prevent fraud and eliminate corruption

At low temperatures, some bacteria are still present. The first use of cold storage still needs to be done to prevent corrosion and eliminate Du to ensure that the cold storage environment is not stained. <>
