What is flash sterilizer?

Definition of flash sterilizer

Flash sterilizer, also called flash autoclave, refers to the process of using saturated steam under heating conditions to make the medium temperature reach high temperature quickly, maintain it for a few seconds and then cool it to the culture temperature relatively quickly to complete the sterilization, flash sterilizer is mainly used for steam sterilization of cavity items and appliances, etc.

Flash sterilizer application

Flash autoclave is suitable for sterilization of high-temperature resistant laboratory metal utensils and medical instruments and articles. It can be used in the pharmaceutical industry to sterilize cloth articles or drugs that do not need cooling and are explosion-proof, such as corks, operation tools, a large number of work clothes, etc. It can also be used in the pharmaceutical industry to produce sanitary materials, dressings, instruments, and other products as sterilization equipment, and can be used for sterilization, fumigation, and drying of herbs. It can also be used for food sterilization.

Flash sterilizer working principle

The working principle of flash sterilizer is to use saturated water vapor as the sterilization medium and apply the method of forcibly excluding the air from the pulsating vacuum using instruments.
Pulsating vacuum is the method of vacuuming the sterilization chamber several times, and after completing one vacuum, putting a certain amount of steam into the sterilizer to make the remaining air fuse with the steam to meet a certain amount of steam at one time, and then implementing the vacuuming operation and entering steam sterilization.
Pre-vacuum is a method of autoclaving to remove the maximum amount of air from the sterilization chamber before entering the steam, and then integrating it into the steam for sterilization.
Therefore, the principle of flash sterilization is that after the microorganism is subjected to heat, the movement of protein molecules will accelerate and hit each other, thus causing the peptide chains to break, and the molecules will change from a regular tight structure to a disorderly diffuse structure, and a large number of hydrophobic groups will be exposed on the surface of the molecules, and they will fuse to form very large aggregates and precipitate and solidify, that is, by irreversibly changing the structure of The purpose of killing microorganisms is achieved by irreversibly destroying proteins and enzymes.

Structure of flash sterilizer

The structure of the flash autoclave machine is as follows:
Pressure vessel
Includes sterilization chamber, jacket, door and other parts connected to the sterilization chamber. It is generally made of stainless steel and has a layer of insulation material.
Sterilization chamber
The space where the items to be sterilized are placed.
Generally a stainless steel structure welded around the outside surface of the sterilization chamber to achieve mechanical reinforcement and temperature control of the sterilization chamber.
Piping system
Steam entry piping: directly connected to the steam source to deliver steam to the sterilization chamber or jacket.
Steam drainage piping: discharges steam condensate.
Sterilization chamber discharge piping: connects the sterilization chamber with the discharge piping, and is the channel for the gas and condensate in the sterilization chamber to be discharged outside.
Water supply line: provides working water for the sterilizer.
Return air line: connects the sterilization chamber to the atmosphere, when the inner chamber is dry, a vacuum is formed, and through the return air line, the inner chamber is balanced with the external atmospheric pressure.

Advantages of using flash sterilizer

Flash autoclave machine sterilization thoroughly, high efficiency, light damage to the items, normal temperature in the operating room, saving energy, manpower, and material resources, in addition, flash sterilizer sterilization effect is good, while the sterilization speed is very fast, this is because of its high sterilization temperature, the general temperature of 130 degrees Celsius or so. And the temperature of both inner and outer layers is the same. At the same time, it will pre-exhaust before sterilization, so it can achieve a 99.9% sterilization effect, which is an excellent sterilization instrument.

How to use flash sterilizer?

1. The flash sterilizer must be placed on a sturdy horizontal surface.

2. Add an appropriate amount of water to the outer pot, put the items to be sterilized into the inner pot, cover the lid, and twist the screw symmetrically.

3. When the pressure gauge pointer reaches 33.78kPa, open the exhaust valve to discharge the cold air, then the pressure gauge pointer drops, when the pointer drops to zero, close the exhaust valve.

4. When the pressure in the pot increases to the required pressure, reduce the fire and maintain the steam pressure for a certain period according to the characteristics of the sterilized items, then turn off the power of fire of the sterilizer and let it cool naturally before slowly opening the exhaust valve to remove the remaining gas before opening the lid to take the items.

Precautions for using flash sterilizer

1. When using the flash sterilizer, the articles to be sterilized should not be placed too tightly.

2. The cold air must be fully removed, otherwise, the temperature inside the pot will not reach the specified temperature and affect the sterilization effect.

3. After sterilization, do not deflate and reduce the pressure, otherwise, the liquid in the bottle will boil violently, wash off the stopper, and overflow or even cause the container to burst. The pressure in the sterilizer must be reduced to the same pressure as the atmosphere before opening the lid.

4. When sterilizing liquids, the liquid should be filled in a heat-resistant glass bottle, with no more than 3/4 of the volume, and the bottle mouth should be made of cotton yarn. Do not use perforated rubber or cork; after sterilization, do not release steam immediately, but wait until the pressure gauge pointer returns to zero before discharging the remaining gas.

5. Do not sterilize different types of items with different sterilization requirements, such as dressings and liquids, etc. together to avoid losses.

6. Nowadays, there are microcomputer automatic control autoclaves, which only need to release cold air, and then the instrument can be automatically timed at constant pressure, and the power will be automatically cut off and the horn will be sounded when the time is up, which is very convenient to use.
