Product Description

 Portable Pressure Steam Sterilizer / retort sterilizer
Product Name   Portable Pressure Steam Sterilizer
Product Model   DN-280A
Scope of application
This portable pressure steam sterilizer was designed and manufactured based on the regulation of national pressure vessel design and other relevant provisions, with Food and Drug Administration Product Registration Certificate and Sanitation Products Disinfection Permits. It comes with full-featured sterilization control system and easy to operate. The highlight is on the function of safety control

1. you will be unable to open the retort lid when there is still some pressure inside the retort chamber
2. no pressure raise in the sealed retort under wrong operation.

This product is made from high quality stainless steel which can meet sanitary request of the sterilization in hospital, dental clinic, school, food and chemical industrial and biological research. This retort can be also used as a sterilization equipment in pilot plant.
Sterilization principle
     Pressure Steam Sterilizer is designed for the use of heat to kill microorganisms principle. Sterilization principle is to use the principle of gravity displacement of the steam from the top down in the sterilizer, the cool air is discharged from the vent, replaced by cold air discharge saturated steam, the use of the latent heat released by steam sterilization to achieve the article . The advantage of using steam heat sterilization method that has a strong bactericidal effect, which can increase the water content of bacterial protein, making it easy to solidification due to heat, the acceleration process dead microorganisms.

Steam sterilizer / steam retort Sterilization principle
Moist heat sterilization describes sterilization techniques that utilize hot air that is heavily laden with water vapor and where this moisture plays the most important role in the sterilization. Heating an article is one of the earliest forms of sterilization practiced. The various procedures used to perform moist heat sterilization process cause destruction of micro-organisms by denaturation of macromolecules.
High pressure in Moist heat sterilization process
A more commonly used method when extended heat is not a concern is to use an autoclave or pressure cooker. When sterilizing in this way, samples are placed into a steam chamber on a shelf or raised floor, and the chamber is closed and heated so that steam forces air out of the vents or exhausts. Pressure is then applied so that the interior temperature reaches 121°C, and this temperature is maintained for between 15 and 30 minutes. This elevated temperature and pressure is sufficient to sterilize samples of any commonly encountered microbes or spores. The chamber is then allowed to cool slowly or by passive heat dissipation; it is rare for forced cooling to be applied, or for pressure to be vented deliberately. Pressure sterilization is the prevailing method used for medical sterilization of heat-resistant tools, and for sterilization of materials for microbiology and other fields calling for aseptic technique.
In cases when items need to be sterilized for immediate use, flash sterilization may be employed. Flash techniques generally run for the minimum time, temperature, or pressure, and may sacrifice some safeguards, such as the abilities to validate with biological indicators or prevent contamination. Additional protocols are generally taken to mitigate the sacrifices; flash sterilization equipment is often kept in an operating room's sterile field, steam-penetrative protective packaging may be used to prepackage items, and specially designed rigid sterilization container systems can be reused.
An easy way to understand the sterilization principle
In retort chamber, high temperature steam raise to top position and cold air in retort chamber will move to the chamber bottom which result to the complete drainage of the cold air from the retort chamber. When the temperature interior the retort chamber is 121degree C, and pressure controlled at 0.1~0.2Mpa, holding this temperature and pressure 10 to 30 minutes so that all the Bacteria and microbes will be killed and the product will be sterilized and gain a longer shelf life.
